[0014]
Next, the operation at the time of the sensor set + answering set (crime prevention mode) for recording an image picked up by the camera device 4b when the human sensor 4a of the sensor camera 4 is detected will be described. First, when the absence setting button B1 of the base unit 1 is pressed, a screen for selecting a “sensor camera notification sound present” mode and a “sensor camera notification sound absent” mode is displayed on the video display monitor 11. This can set whether or not to sound a notification sound when receiving a sensor input signal in the master unit 1, and in the “sensor camera notification sound present” mode, depending on the type of sensor input signal, when the sensor input signal is input It is determined whether or not a notification sound is emitted from the speaker 14. In the “no sensor camera notification sound” mode, the notification sound is not sounded from the speaker 14 when the sensor input signal is input, regardless of the type of the sensor input signal. Here, the “sensor camera notification sound present” mode is selected.
[0015]
Then, the absence setting button B1 and the set display LED 1 are turned on, and the sensor set + absence set state is set. When a sensor input signal is output from the human sensor 4a in this state, the master unit 1 switches the switches SW1 and SW2 so as to connect to the sensor camera slave unit 4. The sensor input signal is a signal different from the call signal output by the camera-equipped doorphone sub unit 3, and the voice circuit block 13 can recognize the sensor input signal and the call signal separately. The audio circuit block 13 further determines whether or not to sound a notification sound from the speaker 14 according to the type of sensor input signal.
[0016]
The sensor input signal output from the sensor camera slave unit 4 includes a sensor input signal with a notification sound (signal with a notification sound) that causes the master unit 1 and the sub-base unit 2 that have received the sensor input signal to generate a notification sound, There are two types of sensor input signals without notification sound (notification signal no signal) that do not sound the notification sound. This is linked to the brightness sensor or timer function of the camera device 4b, so that either a notification sound presence signal or a notification sound absence signal is output according to the brightness or time around the sensor camera slave unit 4. It can be realized by setting. For example, when linked with a brightness sensor, it is possible to automatically switch to output a signal with a notification sound at daytime and a signal without a notification sound at night.
[0017]
FIG. 6 shows the operation of the master unit 1 when the sensor input signal output from the sensor camera slave unit 4 is a notification sound presence signal. After the audio circuit block 13 to which the sensor input signal (signal with a notification sound) has been input sounds a notification sound (for example, pororon) from the speaker 14, the video display monitor 11 rises and enters the calling state, and the call display LED 2 is turned on. Flashes. Then, the image signal from the camera device 4b is input to the video display monitor 11 via the switches SW1, 2, the transformer T1, the amplifier AMP1, and the switch SW3, and three images are recorded in the memory in the video display monitor 11. Further, after sounding the notification sound from the speaker 14, the audio signal from the microphone 4c is immediately input to the audio circuit block 13 via the switches SW1, 2, and the sensor input signal is stored in the memory in the audio circuit block 13. A voice of 16 seconds is recorded from the input.
[0018]
This calling state continues for 30 seconds from the input of the sensor input signal. When the call button B2 of the base unit 1 is pressed in this calling state, the image signal sent from the door phone sub unit 3 with the camera is displayed on the video display monitor 11. Can be displayed and monitored. At this time, the call display LED 2 is turned off. This monitoring state is terminated one minute after the call button B2 is pressed or by pressing the call button B2 again.
[0019]
Next, FIG. 7 shows the operation of the master unit 1 when the sensor input signal output from the sensor camera slave unit 4 is a signal without notification sound. The voice circuit block 13 to which the sensor input signal (signal without sound notification) is input does not sound a sound notification (for example, pororon) from the speaker 14, and the video display monitor 11 is not operated, and only the call display LED 2 is displayed. Flashes. Then, the image signal from the camera device 4b is input to the video display monitor 11 via the switches SW1, 2, the transformer T1, the amplifier AMP1, and the switch SW3, and three images are recorded in the memory in the video display monitor 11. Further, the audio signal from the microphone 4c is input to the audio circuit block 13 via the switches SW1 and SW2, and the audio for 16 seconds is recorded in the memory in the audio circuit block 13 from the input of the sensor input signal. The three images can be recorded by setting an appropriate time in accordance with the movement of the crime prevention mode of the illumination at the imaging location after inputting the sensor input signal. For example, the images are recorded after 3 seconds, 6 seconds, and 9 seconds. Set to Alternatively, the latter two pictures may be recorded in accordance with the sensor input signal re-input timing.
[0020]
Then, the calling state without the notification sound continues for 30 seconds from the input of the sensor input signal. When the call button B2 of the base unit 1 is pressed in this calling state, the video display monitor 11 is started up, and the camera-equipped doorphone sub unit 3 The sent image signal can be displayed and monitored. At this time, the call display LED 2 is turned off. This monitoring state is terminated one minute after the call button B2 is pressed or by pressing the call button B2 again.
[0021]
In the above description of the operation, the case where the base unit 1 selects the “sensor camera notification sound present” mode in which it is determined whether or not the notification sound is emitted from the speaker 14 when the sensor input signal is input depending on the type of the sensor input signal will be described. However, regardless of the type of the sensor input signal, the operation when the “no sensor camera notification sound” mode in which the notification sound is not output from the speaker 14 when the sensor input signal is input will be described below.
[0022]
First, after the absence setting button B1 of the base unit 1 is pressed, the “sensor camera notification sound” mode is selected from the “sensor camera notification sound present” mode and the “sensor camera notification sound absent” mode on the video display monitor 11. Select here. Then, the absence setting button B1 and the set display LED 1 are turned on, and the sensor set + absence set state is set.
[0023]
Further, by interlocking with the brightness sensor and the timer function, the “sensor camera notification sound present” mode and the “sensor camera notification sound absent” mode may be switched according to ambient brightness, time, and the like. For example, when linked with the brightness sensor, the mode can be automatically switched to the “sensor camera alarm sound” mode at daytime and the “sensor camera alarm sound absent” mode at night.
[0024]
The operation of the base unit 1 to which the sensor input signal from the sensor camera slave unit 4 is input in the “no sensor camera notification sound” mode is notified by the sensor input signal in the “sensor camera notification sound present” mode. The operation is the same as that in the case of a soundless signal and is shown in FIG.
[0025]
Next, when the answering setting button B1 is pressed in the sensor set + answering state, the answering setting button B1 and the set display LED 1 are turned off, and the sensor setting + answering set is released. The operation of the base unit 1 in this released state is shown in FIG. 8, no operation is performed by the sensor input signal from the sensor camera slave unit 4, and the audio circuit block 13 does not sound the notification sound from the speaker 14. Recording and recording are not performed when the display monitor 11 is not operating. However, manual monitoring is possible.
[0026]
In this embodiment, the number of images to be recorded in the memory in the video display monitor 11 is three. However, the number of recorded images can be changed by the setting of the master unit 1, and may be set to, for example, one. .
