    Anti-theft alarm system infrared detection function


    [ Content summary ] The function of the infrared detector needs to be used together with the burglar alarm system, that is, it needs to be used with the alarm host in the alarm system, and cannot be used alone. This is the infrared detector of the burglar alarm system. For the function of the infrared detector, we will explain it in detail below for everyone.

    Infrared Detectors


    How infrared detectors work

    After an infrared detector is installed in a shop or home, if an intruder enters the shop or home illegally after setting up an arm, the infrared detector will work at this time, it can detect the human body, and then immediately report the alarm The signal is transmitted to the alarm host, so why the infrared detector must be used together with the alarm host, and then the alarm host will call the user's pre-stored phone number to alarm, and at the same time, activate the alarm siren to scare off intruders.

    The eight major features of infrared detector detection

    (1) Good environmental adaptability, visible light, no matter whether it is at night or in bad weather, it will not bring any bad influence to the infrared detector;

    (2) Concealment is very good, usually receiving signals from the target passively, it is stronger and better than radar and laser detection, and it is not easy to be interfered by any substance;

    (3) Compared with radar systems, infrared detectors are not only small in size, light in weight, but also lower in power consumption;

    (4) The spectral response of the detection is extended from short barge to long wave;

    (5) From unit development to pluralism, from pluralism development to focal plane;

    (6) Development of a wide variety of detectors and systems for infrared detectors;

    (7) Development from single-band detection to multi-band detection;

    (8) Development from a refrigeration type detector to a room temperature detector;

    The infrared detector uses advanced signal analysis and processing technology to provide ultra-high detection and anti-false alarm performance. When an intruder passes through the detection area, the detector will automatically detect human activities in the area; if there is a dynamic movement phenomenon, It sends an alarm signal to the control host.
