Ceiling-mounted motion detectors use an advanced quad-PIR element to provide consistent detection regardless of the direction of movement. The BV-500 offers even more security with its integrated glass break detector.

Temperature compensation for:
• Improved pickup in critical temperatures
• Patented Multi-Level Signal Processing (MLSP) for accurate detection of human infrared energy across a wide range of temperatures
• Sensitivity adjustment for detector configuration for normal or harsh environments
• Protection against high levels of static and voltage transients
• Exceptional immunity to white light
• Excellent immunity to radio frequency (RF)
• Digital signal analysis for uniform detection across the entire coverage pattern
