Description

technical field [0001] The invention relates to a photoelectric anti-theft system. Background technique [0002] At present, there are various types of anti-theft and alarm products on the market. However, the existing anti-theft and alarm products (such as electronic anti-theft devices, infrared alarms, etc.) have complex structures and expensive prices, and their deployment and control areas are narrow in application: now most of the electronic anti-theft alarms for households are Installed at the door, when the door lock is improperly opened, the anti-theft device will be activated to give a sound alarm, and when the thief enters in other ways (such as turning the window), it will not work; Window radar alarms, if you want to achieve a full range of three-dimensional control alarm devices in the family, you must install alarms at the door, window and each room of the residential area, which increases the cost of use. Contents of ...
