Anti-shielding switcher for video surveillance camera

Abstract

The invention relates to an anti-shielding switcher for a video surveillance camera. The anti-shielding switcher comprises a box body and a cover body clamped on the box body. A window and a chamber are arranged on the box body. A guide shaft is arranged in the chamber. A magnet which is capable of rotating around the guide shaft is arranged on the guide shaft. A driving lever which can rotate with the magnet is connected on the magnet. A coil support is disposed outside the magnet. A coil which can drive the magnet to rotate is arranged on the coil support. A slide sheet which is positioned between the box body and the cover body and can move with the rotation of the driving lever is connected on the driving lever. An infrared cut-off filter and a glass sheet which are capable of switching and aiming at the window with the movement of the slide sheet are arranged on the slide sheet. Since the anti-shielding switcher is isolated by the box body and the cover body, the magnet is not easily subjected to external electromagnetic interference and thus does not affect product performance. The anti-shielding switcher for the video surveillance camera is simple in assembling procedures and is convenient for installation.

Description
