Application

Intelligent security- burglar alarm

Wireless infrared detection alarm, uses advanced signal analysis and processing technology. When the intruder enters through the detection area, it sends alarm signal to control panel.

the PIR sensor is suitable for home, residential area, factory, shopping mall, warehouse, and offices.

 

FAQ

1.Can PIR sensor detect animals?

PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human.

 

2.Do PIR sensors work through glass?

No, alarm motion sensors do not work through glass. most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. this is why motion sensors will generally not work through windows, which are usually insulated.
