The siren with dual infrared beams provides reliable perimeter security and minimizes false al when falling from fallen leaves, birds, etc. The lens optical system enhances the beam intensity and has excellent immunity to false al caused by rain, snow, fog, etc. This is an alarm two-beam photoelectric infrared detector, install them in opposite positions. Then there is an infrared region between the two detector parts. When someone passes through the infrared zone and adjusts the response time, the detector will send an alarm signal to the security alarm host (not included here) that uses 2 power adapters to work. Real-time report of holographic points. High-power unique displacement receiving and transmitting components. Full function inspection, environment adaptation and fault lock.
