Description

  The present invention relates to a monitoring device for a house or the like, and more particularly to improvement of a monitoring device suitable for the security of a house or the like.

  In a monitoring device, particularly in a security device such as a house, that is, a monitoring device suitable for crime prevention, fire, etc., for example, a sensor that detects an abnormality and an abnormal signal output from the sensor are operated to activate an image of the monitoring camera. There is known a control device including a control device that captures the image and a monitoring control server that transmits an image captured by the control device via a communication line.

In this monitoring device, as described above, the monitoring camera is actuated using the abnormal signal as a trigger to capture the monitoring location, and the user can check the captured image (see, for example, Patent Document 1). .
JP 2002-15390 A (FIG. 1)

  By the way, in the monitoring device as described above, it is better to be able to grasp various abnormal situations at the monitoring place. Therefore, in addition to the infrared sensor that detects the intruder into the monitoring place, the opening / closing state of the window is detected. It would be preferable for the user to include switches that detect the load applied to the floor by an intruder, a temperature sensor that detects a fire, a gas sensor that detects gas leakage, and the like.

  However, in the case of a thermal sensor using the pyroelectric effect or the thermoelectromotive force effect, the infrared sensor outputs a voltage higher than the reference voltage when it is not irradiated as an abnormal signal when irradiated with infrared rays, Some sensors increase or decrease the electrical resistance of the element due to temperature rise, while others output higher voltages than the normal reference voltage as abnormal signals, while others output lower voltages. Further, if the gas sensor is of a semiconductor type, the electric resistance of the element is reduced when gas leakage is detected, so that a voltage higher than the normal reference voltage is output as an abnormal signal.

  As described above, whether to output a voltage higher or lower than the reference voltage output in normal time when the sensor detects an abnormality depends on the sense principle.

  Therefore, in a monitoring device that receives an abnormal signal input from a sensor, it can be determined whether the voltage signal output from the sensor provided in the monitoring device in advance is an abnormal signal. If the sensor is replaced with a new one, the abnormal signal may not be recognized. To enable the monitoring function, the specified type and type of sensor must be used. Could not add to monitoring device.

  Therefore, the present invention has been developed to improve the above-described problems, and an object of the present invention is to provide a monitoring device that can easily replace and add a sensor.

  The monitoring apparatus according to the present invention is a monitoring apparatus that recognizes an abnormality in a monitoring place when an abnormality signal is input from a sensor that detects an abnormality in the monitoring place. The abnormality signal is predetermined with respect to a voltage signal that the sensor normally outputs. The problem can be solved by setting and changing the voltage signal to either a high voltage signal or a predetermined voltage signal to be a low voltage.

  In addition, the monitoring device of the present invention is a monitoring device that recognizes an abnormality at a monitoring location when an abnormal signal is input from an individual sensor that detects the abnormality at the monitoring location. The problem can be solved by setting and changing for each sensor either a voltage signal having a predetermined high voltage or a predetermined voltage signal having a low voltage with respect to the signal.

  According to the monitoring device of the present invention, it is possible to set and change so that a voltage signal that is a predetermined high voltage or low voltage is recognized as an abnormal signal with respect to a voltage signal that the sensor normally outputs. Regardless of the type, the sensor can recognize an abnormal signal when an abnormality is detected, the sensor can be replaced with another type or type, and the versatility and practicality of the monitoring device can be improved. It is also possible to add other types of sensors to the monitoring device.

  The present invention will be described below based on the embodiments shown in the drawings. FIG. 1 is a diagram illustrating a system configuration of a monitoring apparatus according to an embodiment. FIG. 2 is a flowchart of a processing procedure for setting and changing the recognition of the abnormal signal in the monitoring device according to the embodiment. FIG. 3 is a flowchart of a processing procedure for changing whether or not a control signal can be output in the monitoring apparatus according to the embodiment. FIG. 4 is a flowchart illustrating an operation when an abnormal signal is input to the monitoring device according to the embodiment.

  As shown in FIG. 1, the monitoring device according to one embodiment includes a monitoring camera 1 installed in a house or the like, a plurality of input terminals 40, 41, 42, 43 that connect sensors for detecting an abnormality, A control unit 3 that operates the monitoring camera 1 to acquire an image when receiving an abnormal signal, and a server 5 to which information including image information is transmitted from the control unit 3 via a communication unit 4 such as the Internet. Has been.

  The communication means 4 only needs to be capable of information communication, and is not limited to the Internet, and may be a wired, wireless, mobile phone communication network, or the like.

  The monitoring camera 1 will be described in detail below. The monitoring camera 1 includes a CCD (charge coupled device, not shown) and a lens (not shown), is configured as a CCD camera, and can take a picture of a monitoring place such as a house. In addition, two input terminals 40 and 41 among the input terminals are connected to the infrared sensor 21 and the temperature sensor 22, respectively.

  And the infrared sensor 21 is installed in the location which can sense the presence or absence of the infrared rays which the intruder in the monitoring place emits, and the temperature sensor 22 is installed in the location which can detect the temperature of the monitoring location. .

  In this case, the infrared sensor 21 is a pyroelectric effect type sensor that senses the presence or absence of infrared rays emitted by an intruder to the monitoring place, outputs a low voltage signal during normal times, and outputs a high voltage voltage during abnormal conditions. Output a signal. The temperature sensor 22 is, for example, a thermistor whose electrical resistance increases as the temperature rises, and outputs a voltage signal having a low voltage when the temperature is higher than normal.

  In the monitoring apparatus in this embodiment, an abnormality is detected by the infrared sensor 21 when the intruder enters the monitoring place, and a temperature abnormality is detected by the temperature sensor 22 when the temperature is abnormal at the monitoring place. Become.

  In this embodiment, the control unit 3 includes four input terminals 40, 41, 42, and 43, an A / D converter 31 that converts an analog image signal output from the monitoring camera 1 into a digital signal, an input terminal 40, A / D converter 32 that converts an analog voltage signal input through 41, 42, and 43 into a digital signal, a compression circuit 34 that captures the converted image signal and compresses image information, and control in the monitoring device A main control unit 35 that processes the procedure, a flash ROM that stores the control procedure, and a ram that stores information generated when the arithmetic processing unit 35 processes the control procedure (Romdom access Memory) And a storage device 36 configured to include a plurality of output terminals 37a, 37b, 37c, and 37 that receive a command from the main control unit 35. Control signal and the output control unit 38 capable of outputting is configured to include a communication interface 39 that enables information exchange with the communication means 4 in.

  The surveillance camera 1 is connected to the main control unit 35, and can perform zooming, panning, and photographing in accordance with commands from the main control unit 35.

  Further, one of the output terminals 37a, 37b, 37c, and 37d in the control unit 3 is connected to the illumination device 6 that irradiates the photographing range of the monitoring camera 1, and the other output terminals 37a, 37b, 37c, and 37d are connected. One is connected to an alarm device 7 capable of generating an alarm sound.

  In this case, the output control unit 38 can output a voltage as a control signal to the illumination device 6 and the alarm device 7 via the output terminals 37a, 37b, 37c, and 37d, respectively. In addition, the alarm device 7 can generate and extinguish an alarm sound.

  And if this control part 3 judges that the voltage signal from the infrared sensor 21 or the temperature sensor 22 is an abnormal signal fundamentally, it will operate the monitoring camera 1 and will image | photograph a monitoring location, The image is compressed by the compression circuit 34 and the compressed image information is transmitted to the server 5 from the communication interface 39 via the communication means 4 together with its own recognition ID.

  The control unit 3 can select whether or not to output control signals to be output to the output terminals 37a, 37b, 37c, and 37d via the output control unit 38. This output permission / inhibition can be set by a command input to the control unit 3 from a portable terminal or a terminal (hereinafter referred to as a terminal or the like) 10.

  Therefore, for example, the infrared sensor 21 detects that an intruder has entered the monitoring place as an abnormality, the voltage signal is input to the input terminal 40, and if the voltage signal is an abnormality signal, the control unit 3 When the judgment is made, it is possible to activate the illumination device 6 and / or the alarm device 7 together with the photographing of the monitoring location of the surveillance camera 1, or not to activate both of them.

  If the lighting device 6 is turned on prior to the operation of the monitoring camera 1, the infrared sensor 21 detects that there is an intruder at the monitoring location and the monitoring camera 1 captures the monitoring location. In addition, the intruder can be specified even when the abnormality occurs at night.

  Further, if an alarm is generated in the alarm device 7, a timely warning can be given to an intruder, and theft can be prevented beforehand.

  That is, the operation of the monitoring device for the abnormal signal can be linked not only to the photographing of the monitoring camera 1 but also to the lighting device 6 and the alarm device 7 connected to the monitoring device.

  Further, in this monitoring device, an abnormal signal can be output individually corresponding to the abnormal type of the sensor means 2, but this control unit 3 corresponds to the abnormal signal corresponding to the abnormal type. The user can select whether or not to output the control signal.

  Therefore, for example, the illumination device 6 is turned on for an abnormal signal of the infrared sensor 21, but an alarm sound can be generated by the alarm device 7 for the abnormal signal of the temperature sensor 22. .

  In this way, in this monitoring device, since it is possible to select whether or not the control signal can be output, it is possible for the user of the monitoring device to perform an operation according to his / her preference, and to set the user Therefore, it is possible to realize a security system with a high degree of freedom.

  On the other hand, the server 5 includes a communication interface 51 that enables information exchange with the communication unit 4 and a specifying unit that specifies a user and a monitoring place by referring to the user database 52 based on the recognition ID transmitted from the control unit 3. 53, an e-mail creating unit 54 for creating an e-mail, an information processing unit 55 for processing information transmitted from the control unit 3, and an image database 56 for storing image information.

  In the server 5, when the recognition ID and the image information are received from the control unit 3, the specifying unit 53 specifies the user and the monitoring place by referring to the user database 52 based on the recognition ID, and the information processing unit 55 stores the image information in the image database 56, and the mail creation unit 54 sends the mail address of the user's terminal 10 or the like registered in the user database 52 in advance to the mail of the content in which the abnormality occurred. Create, attach image information, and send an e-mail to the e-mail address.

  The mail creation unit 54 can convert the format of the image information so that the user matches the terminal 10 that receives the email, and the communication interface 51 matches the terminal 10 that the user receives the email. Thus, the communication protocol can be appropriately converted.

  Further, when the server 5 transmits mail, the telephone service server may be used once.

  In addition, the user can directly access the monitoring device 1 from the terminal 10 or the like via the communication means 4 to remotely operate the monitoring camera 1, the lighting device 6, and the alarm device 7.

  Specifically, when the user gives a command from the terminal 10 or the like to the control unit 3, the surveillance camera 1 takes a picture of the monitoring location, pans and zooms the surveillance camera 1, and further sends a control signal to the control unit 3. By making it output, the lighting device 6 can be turned on / off, the alarm device 7 can generate an alarm sound or the alarm sound can be extinguished.

  In this monitoring device, when the control unit 3 recognizes that each voltage signal input from the sensor means 2 to the input terminals 40, 41, 42, 43 is an abnormal signal, a predetermined monitoring operation is performed. However, each abnormal signal recognized by the control unit 3 is set and changed to either a voltage signal that becomes a predetermined high voltage or a voltage signal that becomes a predetermined low voltage with respect to the voltage signal that the sensor means 2 normally outputs It is possible to do.

  Specifically, this setting is performed according to the processing procedure shown in FIG. 2, and this processing procedure is stored in the storage device 36 of the control unit 3 and is controlled via the communication means 4 from the user terminal 10 or the like. If there is an access to the unit 3, it is executed as an interrupt process, and in step 80, the control unit 3 requests input of a recognition ID and password.

  When the user receives the recognition ID and password from the terminal 10 or the like, the process proceeds to step 81 where the control unit 3 refers to the recognition ID and password stored in the storage device 36 and enters the input recognition. It is determined whether the ID and password match.

  As a result of this determination, if the recognition ID and the password match, the process proceeds to step 82. If not, the process ends, and the process is not resumed unless there is another access.

  In the above example, the recognition ID is input. However, when a unique user ID is given to the user, the determination may be made based on the match between the user ID and the password.

  In step 82, the user selects either monitoring device control or output settings. Specifically, a character string “control”, “output setting” and “input setting” and a selection button are displayed in front of each character string on the display device of the user terminal 10 or the like, and the user uses the selection button. To prompt the above selection.

  Then, when the user selects control of the monitoring apparatus, the process proceeds to the above-described remote operation process. When the output setting is selected, the process proceeds to an output setting process described later, and when the input setting is selected, the process proceeds to step 83.

  In step 83, an input terminal to which an abnormal signal is input is selected. In this embodiment, the input terminals 40 and 41 to which the infrared sensor 21 or the temperature sensor 22 is connected are selected. Specifically, since there are four input terminals, a character string “input 1”, “input 2”, “input 3”, and “input 4” and a character string of each character string are displayed on the display device of the user terminal 10 or the like. A selection button is displayed before and the user is prompted to make the selection using the selection button.

  If the character string “infrared sensor” can be associated with the character string “input 1”, “infrared sensor” may be displayed instead of the character string “input 1”. Similarly, “temperature sensor” may be displayed for “input 2”.

  In step 84, input settings related to the sensor selected by the user are performed. In this embodiment, since there are four input terminals 40, 41, 42, and 43, for each of the input terminals 40, 41, 42, and 43, a voltage signal that is normally output by a sensor connected to each input terminal is obtained. When the control unit 3 recognizes a voltage signal having a predetermined high voltage as an abnormal signal, conversely, when “high” is recognized, a voltage signal having a predetermined lower voltage than the normal voltage signal is recognized as an abnormal signal. In order to prompt the user to select “low”, “high” and “low” are displayed on the display device of the terminal 10 or the like to prompt the user to select the user. Is stored in the storage device 36.

The setting information includes, for example, four input terminals 40, 41, 42, and 43. Therefore, the setting information is related to the abnormal signal of the infrared sensor 21 as the abnormal signal set value I _N (N = 1, 2, 3, 4). if setting information, the value of the abnormality signal setting value I ₁ is set, if the setting information associated with abnormal signal of the temperature sensor 22, the value of the abnormality signal setting value I ₂ is set, respectively the storage device It is stored in 36 flash ROMs.

The value of the abnormal signal set value I _N (N = 1, 2, 3, 4) is set to 1 meaning high or 0 meaning low.

In this embodiment, the control unit 3 recognizes that the voltage signal input from each of the input terminals 40, 41, 42, and 43 is an abnormal signal based on the abnormal signal set value I _N described above. Will be decided.

  Subsequently, in step 85, in order to prompt the user to finish the input setting, a character string “end setting” and “continue setting” and a character string before each character string are displayed on the display device of the user terminal 10 or the like. A selection button is displayed on the screen, and the user is prompted to make the selection using the selection button.

  When the user selects the end of setting, the setting process is ended. When the user desires to continue the setting, the process proceeds to step 83.

When the above setting is completed, the control unit 3 performs a restart process. During restart, but the monitoring device program is executed following the OS (Operating System), this time, the abnormality signal setting value I _N stored in the flash ROM of the storage device 36 in step 84 is read only once, When the monitoring device program is executed, the read abnormal signal setting value _IN is always a valid value during subsequent processing on the monitoring device program.

  Therefore, unless the restart process is performed, the output set value set in step 84 is not valid, and the output set value changed by the output setting is valid only after the restart process is performed. It becomes.

  Further, when performing the restart process, the control unit 3 transmits information indicating that the restart process has been performed together with the identification ID and information on the output setting value to the server 5 as restart information.

In the server 5 that has received this transmission, first, the specifying unit 53 refers to the user database 52 based on the identification ID, specifies the user and the monitoring location, and then the mail creating unit 54 stores the mail registered in the user database. addressed to the address, the monitoring device is a content of the abnormality signal setting value I _N set in the step 84 that it has restarted create an e-mail as text, to the terminal or the like 10 of the user.

Therefore, whenever the user changes the output setting in the monitoring device, the user can always confirm that the monitoring device has been restarted, and can confirm again the abnormal signal setting value _IN that the user has changed.

  In the above description, the voltage signal output from the sensor unit 2 in the normal state is set and changed so that a voltage signal having a predetermined high voltage or low voltage is recognized as an abnormal signal. It may be possible to set and change the values of the high voltage and the predetermined low voltage.

  In this monitoring device, as described above, setting and changing are performed so that a voltage signal that is a predetermined high voltage or low voltage is recognized as an abnormal signal with respect to the voltage signal that the sensor means 2 outputs in normal time. Because it is possible, it is possible to recognize an abnormal signal when the sensor detects an abnormality regardless of the type and type of the sensor, and the sensor can be replaced with another type or another type. It is possible to improve the performance, and it is also possible to add other types of sensors to the monitoring device.

  Subsequently, when the user selects “output setting” in step 82, the control signal output to the output terminals 37a, 37b, 37c, and 37d of the control unit 3 is set according to the processing procedure shown in FIG. Is called.

  In step 90, a sensor that outputs an abnormal signal is selected. In this embodiment, specifically, the infrared sensor 21 or the temperature sensor 22 is selected. In this embodiment, since there are four input terminals, a character string “input 1”, “input 2”, “input 3” and “input 4” and a character string of each character string are displayed on the display device of the user terminal 10 or the like. A selection button is displayed before and the user is prompted to make the selection using the selection button.

  If the character string “infrared sensor” can be associated with the character string “input 1”, “infrared sensor” may be displayed instead of the character string “input 1”. Similarly, “temperature sensor” may be displayed for “input 2”.

  In step 91, an output setting related to the sensor selected by the user is performed. In this embodiment, since there are four output terminals 37a, 37b, 37c, and 37d, on and off are selected for each of the output terminals 37a, 37b, 37c, and 37d. 3 stores the setting information in the storage device 36.

The setting information includes, for example, four output terminals 37a, 37b, 37c, and 37d, so that the output setting value F _XN (X = 1, 2, 3, 4, N = 1, 2, 3, 4) is used. If the setting information is related to the abnormal signal of the infrared sensor 21, the value of the output setting value F _1N (N = 1, 2, 3, 4) is set, and the setting information related to the abnormal signal of the temperature sensor 22 is set. If there is, the value of the output set value F _2N (N = 1, 2, 3, 4) is set and stored in the flash ROM of the storage device 36, respectively.

The value of the output set value F _XN (X = 1, 2, 3, 4, N = 1, 2, 3, 4) is set to 1 meaning on or 0 meaning off.

In this embodiment, whether or not the control signal can be output to each of the output terminals 37a, 37b, 37c, and 37d is determined based on the output set value F _XN described above.

  Subsequently, in step 92, in order to prompt the user to finish the output setting, a character string “end setting” and “continue setting” and a character string before each character string are displayed on the display device of the user terminal 10 or the like. A selection button is displayed on the screen, and the user is prompted to make the selection using the selection button.

  When the user selects the end of setting, the setting process is ended. When the user desires to continue the setting, the process proceeds to step 90.

When the above setting is completed, the control unit 3 performs a restart process in the same manner as at the end of the input setting process. At the time of restart, the monitoring device program is executed following the OS (operating system). At this time, the output set value F _XN stored in the flash ROM of the storage device 36 is read only once at the above step 94, In executing the monitoring device program, the read output setting value F _XN is always a valid value during the subsequent processing on the monitoring device program.

  Therefore, unless the restart process is performed, the output set value set in step 91 is not valid, and the output set value changed by the output setting is valid only after the restart process is performed. It becomes.

  Further, when performing the restart process, the control unit 3 transmits information indicating that the restart process has been performed together with the identification ID and information on the output setting value to the server 5 as restart information.

  In the server 5 that has received this transmission, first, the specifying unit 53 refers to the user database 52 based on the identification ID, specifies the user and the monitoring location, and then the mail creating unit 54 stores the mail registered in the user database. To the address, an e-mail is created with text indicating that the monitoring device has been restarted and the contents of the output setting value, and transmitted to the user terminal 10 or the like.

  Therefore, whenever the user changes the output setting in the monitoring device, the user can always confirm that the monitoring device has been restarted, and can check again the output setting value that the user has changed.

  If the user does not receive the e-mail, the monitoring device is not performing the restart process, so confirm that the changed abnormal signal setting value or output installation value is not valid. Thus, the user can confirm that the setting change has failed, and there is no risk of operating the monitoring device without noticing the setting change mistake.

  Further, when the abnormal signal setting value or output setting value is changed even though the user has not changed the setting of the monitoring device, the abnormal signal setting value can be obtained by a third party without permission by receiving the e-mail. Or the output set value has been changed, or for some reason, for example, the power supply is turned off once, the user can know that the monitoring device has been restarted, and by checking the abnormal signal set value or output set value information If there is no change in the set value, or if there is no abnormality in the abnormal signal set value or output set value, it is possible to immediately recognize the abnormality of the monitoring device, and the user can immediately cope with these abnormal situations. .

  That is, in this monitoring device, not only the degree of freedom of setting for operation is increased, but also the safety can be increased because the user can immediately cope with an abnormal situation.

  Although only the restarted information may be transmitted during the restart process, in this case, it is not possible to immediately know whether the monitoring device itself is abnormal or the output setting value has been changed, The user can be notified of the abnormality and given an opportunity to access the monitoring device, and the user can visually confirm the monitoring location by remote operation, so the crime prevention performance is improved.

  In this embodiment, at the time of restart, the server 5 creates an e-mail and transmits the e-mail to the user's terminal 10 or the like. Instead, the user's portable terminal is a cellular phone. In such a case, the control unit 3 may directly call the mobile phone and inform the user that the restart process has been performed by voice.

  Incidentally, in the present embodiment, the setting and change of the abnormal signal set value, the setting and change of the output set value, and the remote operation, the control unit 3 is directly accessed from the user terminal 10 or the like. A program for executing the above-described output change and remote operation processing is stored in a storage device (not shown) of the server 5 so as to access the server 5, and the control unit 3 stores the output setting value. The minimum information necessary for the change and the remote operation may be transmitted, or when an information input device such as a keyboard can be directly connected to the control unit 3 to input information. May access the control unit 3 directly from this information input device so that the above settings and changes, operation of the surveillance camera, etc. can be performed.

  The operation of the monitoring apparatus configured as described above will be described with reference to the flowchart shown in FIG.

  In step 100, the monitoring device determines whether or not an abnormal signal is input from the sensor means 2. If there is an abnormal signal input, the process proceeds to step 101, and if there is no abnormal signal input, It continues to determine whether or not there is repeated input until a repeated abnormal signal is input.

The abnormal signal of whether or not an input judgment, whether the voltage signal inputted to each input terminal 40, 41, 42, 43 meets the criteria set by the above-described abnormality signal setting value I _N It will be judged by.

  Note that the determination in step 100 is that there is an abnormal signal when the infrared sensor 21 and / or the temperature sensor 22 of the sensor means 2 outputs an abnormal signal. Further, when a sensor is added to the other input terminals 42 and 43, if an abnormal signal is input in the same manner, it is determined that there is an abnormal signal.

Subsequently, at step 101, the control unit 3 generates an output flag Z _N (N = 1, 2, 3, 4) for outputting a control signal to each of the output terminals 37a, 37b, 37c, 37d.

Output flag _{Z N} are each one of the output terminals 37a, 37b, 37c, a value indicating whether or not to output a control signal to 37d, in this embodiment, the output flag _{Z 1} to the output terminal 37a correspondingly, below, the output flag _{Z 2} output terminal 37b, output flag _{Z 3} to the output terminal 37c, an output flag _{Z 4} to the output terminal 37d, respectively correspond.

Upon generation of the output flag Z _N, when only the infrared sensor 21 is outputting an abnormality signal, the output flag Z _{N =} F _1N, if only the temperature sensor 22 is outputting an abnormality signal, When the output flag Z _N = F _2N and both the infrared sensor 21 and the temperature sensor 22 output an abnormal signal, the value of the output flag Z _{N is} the value of the logical sum of F _1N and F _2N. .

Then, in step 102, among the output flag _{Z N,} If the value is 1 the corresponding output terminals 37a, 37b, 37c, and outputs a control signal to 37d.

  Further, in step 103, the control unit 3 drives the monitoring camera 1 to photograph the monitoring location, compresses this image information by the compression circuit 34, and temporarily stores it in the storage device.

  In step 104, the control unit 3 transmits the compressed image information together with the identification ID from the communication interface 39.

  Subsequently, the process proceeds to step 105, and when the arbitrarily set time has elapsed, the control unit 3 stops outputting the control signal and ends this process.

  In this monitoring apparatus, the processing from step 100 to step 105 described above is repeated, and abnormality of the monitoring location is always detected and monitoring location is continuously monitored.

  The processing at the monitoring place is as described above. On the other hand, when the server 5 receives the information from the control unit 3 in step 104, the specifying unit 53 specifies the user, and the mail creating unit 54 displays the user's terminal or the like. The text and image information indicating that an abnormality has been detected are transmitted to 10. Note that information on the occurrence time of the abnormality may be included in the text of the e-mail.

  Further, the control output may be stopped by allowing the user to stop the control output by sending a remote operation command from the terminal 10 or the like to the control unit 3.

  As described above, since the voltage signal output from the sensor unit 2 in a normal state can be set and changed so that a voltage signal having a predetermined high voltage or low voltage is recognized as an abnormal signal, the user can set the degree of freedom. Therefore, it is possible to realize a security system with a high degree of freedom.

  And, for example, in this monitoring device, the operation of the monitoring device for the abnormal signal can be linked not only to the photographing of the monitoring camera 1, but also to the lighting device 6 and the alarm device 7 connected to the monitoring device, or It is possible to prevent both of them from operating, and even if the time of occurrence of an abnormality is night, it is possible to identify an intruder and give a timely warning to the intruder. This can prevent theft.

  The shape of the output terminal and the control signal are arbitrarily set. For example, if the shape of the output terminal is the same as that of the outlet and the control signal is set to an AC voltage of 100 V, it is used particularly for crime prevention or disaster. Not only devices that can be used, but also household devices such as radios, televisions, washing machines, etc. can be activated, which allows intruders who have entered unmanned surveillance locations to perceive life sounds and steal It is also possible to prevent this.
