The outer diameter of the outer end of the upper part of the baffle plate 2 is larger than the outer diameter of the lens 4 of the wireless camera body. When the shielding plate 2 is in a vertical state, the upper part of the shielding plate is positioned at the front end of the lens 4 of the wireless camera body and completely shields the lens, the magnetic acting force of the magnet sheet 3 at the left end acts on the left reed pipe GH1, the movable contact and the fixed contact inside the reed pipe GH1 are opened, when the shielding plate 2 rotates by 90 degrees, the lens 4 is not shielded at the upper part of the shielding plate, the magnetic acting force of the magnet sheet 3 at the right end acts on the reed pipe GH2 at the right lower part, and the movable contact and the fixed contact inside the reed pipe GH2 are opened.

Through the above, after a person enters the fortification area, the lens can be opened, and the on-site image shooting work is ensured. When a person leaves the site, the person is no longer in the detection range of the detection head of the photoelectric detection switch A2, the 3 pins of the photoelectric detection switch A2 do not output high level any more and enter the base electrode of the NPN triode Q1, the NPN triode Q1 is cut off, further the PNP triode Q2 is cut off and the negative power supply input end of the relay K1 is powered off, the relay K1 is powered off and does not attract the two control power supply receiving ends and the two normally open contact ends to be opened respectively, the two control power supply input ends and the two normally closed contact ends to be closed respectively, and meanwhile, the relay K2 is powered off and does not attract the two control power supply input ends and the two normally open contact ends to be opened, so that the wireless camera body A3 can be powered off and does not work any more. After the relay K1 loses power and does not attract the two control power receiving ends and the two normally closed contact ends of the relay K1 to be closed respectively, the negative pole and the positive pole of the motor speed reducing mechanism M1 can be electrified, the power output shaft of the motor speed reducing mechanism M1 drives the shielding plate 2 to rotate anticlockwise, when the shielding plate 2 rotates to be close to a vertical state, the lens 4 is shielded by the shielding plate 2, the magnetic acting force of the left magnet piece 3 acts on the left reed pipe GH1, the movable contact and the static contact inside the reed pipe GH1 are opened, and because the two wiring ends of the reed pipe GH1 are connected between one normally closed contact end of the relay K1 and the negative pole power supply input end of the motor speed reducing mechanism M in series through the wires, the motor speed reducing mechanism M can lose power and does not drive the shielding plate to move any more, and the phenomenon that the rotation angle is too large and brings adverse effects to the whole work of equipment is avoided. Through the above, nobody when seting up defences regional activity, the camera lens can be sheltered from and wireless camera body can lose the electricity, has realized having saved the electric energy purpose from this to prevented as far as possible that the camera lens is dirty to the adverse effect that image acquisition effect brought.
