1. Technical Features
1. Patented appearance, the shell is thickened with imported PC material, anti-aging, anti-violent damage, durable (patent).
2. Sealed and waterproof design, protection level reaches IP66, suitable for indoor and outdoor installation in various environments;
3. Adopt the company's professional intrusion detector research and development test database + exclusive rake encryption algorithm to effectively filter out various possible false alarms, and only alarm for real intrusions.
4. A variety of alarm trigger conditions are optional, and users can set arbitrarily according to the on-site environment, with better stability and stronger applicability.
5. Four operating frequencies are optional, which can achieve 360° no dead angle prevention around the target area, and the detectors do not interfere with each other.
6. Intelligent temperature compensation and environmental self-adaptation design, calmly cope with various complex environments.
7. The receiver comes with a color LED display, real-time display of signal strength and working parameters, the working status of the detector is clear at a glance, and the installation and debugging are accurate and quick (patent).
8. The internal display circuit is designed for automatic dormancy, which is energy-saving and environmentally friendly.
9. Optimized military-grade devices, suitable for -40℃ ∽ +70℃ ambient temperature, regardless of severe cold and heat, the detector's working quality is as stable as a rock.
10. Three-dimensional protection design, intruders can be reliably detected in various forms such as drilling, climbing, squatting, run-ups, and ladders, and there is nowhere to hide!
