What is an infrared fence alarm?
Infrared fence (also called "infrared railing") is a kind of active infrared radiation. It uses multiple beams of infrared light to shoot. The transmitter emits infrared light to the receiver in the form of "low frequency emission and time division detection". When any two or more rays emitted by the transmitter are blocked for more than 30ms, the receiver immediately outputs an alarm signal. When a small animal or small object blocks one of the lights, the alarm will not output an alarm signal.
Advantages of the infrared fence alarm:
2. Intelligent light intensity detection: reduce power consumption and reduce false alarms;
4. Cross-infrared radiation: completely avoid direct sunlight interference (unique technology);
Application of infrared fence alarm:
Infrared fence is a new type of home anti-theft guard window and balcony front-end product that replaces the "iron bunker" and traditional technology to prevent the use of door and window magnetic control switches, curtain detectors, etc., and is powerful with various anti-theft alarm controllers. Anti-theft alarm system. Depending on how it works, it can also be extended for a variety of uses, such as indoor parking lot entrance and exit vehicle detection.
Infrared fence alarms are widely used in urban security, community, factories, companies, schools, homes, villas, warehouses, resources, petroleum, chemicals, gas transmission and distribution and many other fields.
Infrared fence alarm product features:

Active infrared technology is commonly used in perimeter infrared radiation systems, and is available in a variety of distance specifications.
Passive infrared detectors, can be divided into double, three and so on! More use in indoor alarm systems.
The infrared radiation system is composed of transmitting and receiving devices, and the transmitting end actively emits infrared waves and receives at the receiving end! Passive infrared is passively sensing the infrared waves emitted by the human body! That is to say: an active infrared that emits an infrared signal, which does not emit an infrared signal itself, but detects an infrared wave of a human body or an object to become a passive infrared. The electronic pulse fence system is mainly composed of a set of pulse emission, alarm and integrated controller and electronic fence. Typically, the electronic fence is installed outdoors, along an existing wall (such as a brick wall, concrete wall, or iron fence) with a probe attached to the proximal end. It is tangible in appearance, similar to the grid. Infrared radiation: It uses infrared light to emit diodes through LED infrared light, and then performs focusing processing through optical mirrors to transmit light to a long distance, which is accepted by the light receiver. An alarm is issued when the light is blocked.
