Among the most technologically advanced detectors available, the WS4904 passive infrared detector (PIR) achieves superior detection and false alarm prevention through digital signal analysis. Digital information is more accurate analyzed using software and is not subject to signal degradation caused by amplification, noise, distortion or signal clipping. Built with reliable 433 MHz technology, the detectors features the latest low-power RF technology to extend battery life.

Features:

• Reliable 433 MHz technology
• Provides pet immunity up to 27 kg
• Digital signal analysis for consistent detection throughout the coverage pattern
• Patented Multi-Level Signal Processing (MLSP) for accurate detection of human IR energy over a broad range of temperatures.
• High traffic shutdown
• 1 Long-life lithium battery included.
