After the camera A3 works by power, the camera A3 transmits the field video data out through the GPRS module A4 and the wireless mobile network; the remote user can master the site situation in real time, and good safety advantage can be obtained. Through the aforesaid, when someone is close to the house door within a certain time in this novel application (camera A3 and GPRS module A4, when warning subcircuit etc. do not have the electricity, standby current 5mA)), the video monitoring equipment body is in the state of losing power, when the outdoor personnel has not opened the door after a certain time (it is possible that the criminal of law violation prizes the door or unblanks), just the work of getting power and with on-the-spot video signal teletransmission, play under the good safety action prerequisite, can also reach the power saving purpose.

In practical situations, after the mobile phone motherboard a6 receives the short message content, the keyboard of the mobile phone motherboard a6 indicates that the light emitting diode VL emits light under the function of the keyboard, so that the high level output by the anode of the light emitting diode VL is reduced voltage and limited current through the resistor R to trigger the conduction of the silicon controlled rectifier VS, and then the buzzer B2 is powered on to sound and visually prompt that the person in the material management room has abnormal conditions at home of the resident and checks the short message content in time (mainly preventing the short sound of the mobile phone motherboard from being too small and the prompting time from being limited, and the person in the material management room does not hear the prompt). After the thyristor VS is turned on, the wireless transmitting circuit module a7 will work, and because the two contacts of the first wireless signal transmitting button S are connected together, the wireless transmitting circuit module a7 will transmit the first path of wireless close signal at this moment. Until the personnel in the subsequent object management room close the power switch SK, the buzzer B stops sounding, and the wireless transmitting circuit module A7 also stops transmitting wireless signals (until the power switch SK is closed and the power switch SK is opened to prepare for the next use).

As shown in fig. 1, 2, 3, 4, 5, and 6, after the wireless transmitting circuit module a7 transmits the first path of wireless close signal, the wireless receiving circuit module A8 receives the first path of wireless close signal within a range of 1500 meters, and further, the pin 4 of the wireless receiving circuit module A8 outputs a high level, and the high level is reduced voltage and limited current through the resistor R4 to enter the base of the NPN triode Q3, so that the NPN triode Q3 is turned on and outputs a low level at its collector to enter the negative power input terminal of the buzzer B1, and the buzzer B1 is powered on to generate a loud sound (until the power switch S is turned off). Through the aforesaid, this is novel if there is the resident family to take place unusually, managers does not on duty in thing pipe room, receiving mechanism can send wireless signal for thing pipe personnel's suggestion mechanism, the suggestion it in time gets back to and looks over specific user's family and has taken place the abnormal conditions in thing pipe room, thing pipe personnel according to the concrete user position of living that the SMS shows digit, just can arrive the scene and find the condition very first time, the criminal behavior that will probably take place eliminates in the state of sprouting, this novel can gain better security effect, and improved product market competition. In fig. 4, 5 and 6, resistances R1, R5, R7, R6 and R, R4 are 1M, 470K, 1K, 47K, 4.7K and 1K, respectively; the model numbers of NPN triodes Q1, Q4 and Q3 are 9013; the model of the PNP triode Q5 is 9012; relay K1 is a DC12V relay; the buzzers B, B2 and B1 are active continuous sound buzzer alarm finished products of SF12V, SF5V and SF5V types respectively; the thyristors VS and VS1 are plastic-sealed one-way thyristors of model MCR 100-1; the electrolytic capacitor C1 was model 10 μ F25V.
