As shown in fig. 1, 2 and 3, the power input ends 1 and 2 pins of the power module A1 and the two poles of the ac 220V power supply are respectively connected by wires, the power output ends 3 and 4 pins of the power module A1 and the power input end relay K1 positive electrode power input end of the detection circuit and the emitter electrode of the NPN triode Q1, the relay K3 positive electrode control power input end and the negative electrode control power input end of the control circuit, the 1 pin and the 2 pin of the power input end short message module A4 of the alarm circuit are respectively connected by wires, and the normally closed contact end and the normally open contact end of the power output end relay K1 of the detection circuit are respectively connected with the 1 pin of the signal input end time relay module A3 of the control circuit and the positive electrode power input end of the relay K3 by wires.

After the camera body 1 is powered on, the camera body 1 remotely transmits on-site image data through optical fibers, and a remote monitoring person can know on-site conditions in real time through a display screen and the like. In the utility model, when no one gets into the monitoring area of camera body 1 outside three meters (specific interval is adjustable, say district enclosure corner personnel pass through less region), the 3 foot of pyroelectric detection module A2 does not export high level, then relay K1 can not get the electricity actuation, and the positive and negative dipoles of motor reduction gears M1 of later stage also can not get the electricity, and glass board 52 is located camera body 1's upper end perpendicularly, like this, camera body 1 normally clear gathers on-the-spot video image. When a person enters the monitoring area of the camera body 1 within three meters, the 3-pin output high level and the high level of the pyroelectric detection module A2 are divided by the adjustable resistor RP1 and the resistor R1, the voltage reduction and the current limiting of the resistor R2 enter the base electrode of the NPN triode Q1, the collector electrode of the NPN triode Q1 is conducted to output the high level to enter the negative electrode power supply input end of the relay K1, the relay K1 is electrified to suck the control power supply input end and the normally open contact end of the relay K1 to be closed, the control power supply input end and the normally closed contact end of the relay K3 are electrified to suck the control power supply input end and the normally open contact end of the relay K3 to be closed, and the time relay module A3 cannot work electrically. After the relay K3 is electrified and attracted, the power input ends of the positive electrode power supply and the negative electrode power supply of the motor reducing mechanism M1 are electrified, the power output shaft drives the toughened glass plate to rotate anticlockwise by about 180 degrees, the glass plate 52 rotates to the front end of the shell of the camera body 1, the lens of the camera body 1 is completely shielded, and illegal entering personnel are prevented from violently smashing the lens (although the thicker glass plate can influence the definition of the lens, the scene video image can be continuously collected and transmitted to the far end). When the glass plate 52 is rotated into position, the magnet CT approaches the reed switch GH, and the internal contacts of the reed switch GH are opened. Because the two wiring ends of the reed switch GH are connected in series between one normally open contact end of the relay K3 and one power input end of the motor reducing mechanism M1 through the lead, the motor reducing mechanism M1 loses power at the moment, and the motor reducing mechanism M1 is prevented from driving the glass plate to rotate anticlockwise and uncontrollably, so that the toughened glass plate 52 cannot effectively shade the front end of the lens.

As shown in fig. 1, 2 and 3, when a person entering the site leaves the range of the detection head of the pyroelectric detection module A2, the 3 pin of the person does not output a high level any more, then the relay K1 cannot be electrified and closed, the control power input end and the normally open contact end of the relay K1 are opened, and the control power input end and the normally closed contact end of the relay K1 are closed after the relay K1 is powered off, so that the relay K3 cannot be electrified and closed any more, the control power input end and the normally open contact end of the relay K3 are opened, and the time relay module A3 can be electrified and operated. After the time relay module A3 is powered on, a high level (for example, 3 seconds) is output to the positive power input end of the relay K2 by a 9-pin for a certain time under the action of an internal circuit, so that the control power input end and the normally open contact end of the relay K2 are powered on, the negative positive electrode power input end of the motor speed reducing mechanism M1 is powered on after the relay K2 is powered on, the power output shaft drives the toughened glass plate to rotate clockwise by about 180 degrees, the glass plate 52 rotates to the upper end of the shell of the camera body 1, and the lens of the camera body 1 is not shielded any more, and the camera body normally shoots. When no tool is used for destroying the camera body and the lens, the mercury liquid level in the mercury switch W can not submerge two contacts, then the short message module A4 can not send out a short message, when the tool is used for destroying the camera body and the lens, the mercury liquid level in the mercury switch W can submerge the two contacts at the moment of vibration due to the vibration acting force of the damage, then the 3 feet of the short message module A4 can input a low-level signal, then the short message module A4 can send out a short message stored in the short message module A4, after the mobile phone of a relevant person with the remote end connected with the short message module A4 receives the short message, the situation that a person is in violent damage to the camera body 1 on the spot can be known for the first time, and various losses of a monitoring area can be reduced as far as possible.
