Dependable & Secure: This Yohii laser alarm with dual infrared beams offers reliable perimeter protection, reducing false alarms caused by falling leaves, birds, etc. Lensed optics enhance beam strength and provide excellent resistance to false alarms from rain, snow, mist, etc. Principle: This is a two-beam photoelectric infrared detector (ABT) with a range of 60m. Install the units at opposite positions. An infrared zone is then created between the two detector components. When someone crosses the infrared zone for the adjusted response time, the detector sends an alarm signal to the security alarm host (not included) and works with 2 power adapters. Powerful Function: Holographic spot real-time reporting. Unique displacing receiving and transmitting parts with high power. Full-function self-checking, environmental self-adaptation, and trouble locking. Durable: The powerful automatic adjustment design automatically adjusts transmit power based on environmental conditions, greatly extending the operational endurance of the launching tube while reducing power consumption. Scope of Application: Ideal for installation in security systems for schools, office buildings, hospitals, home yards, etc
