PIRAMID Indoor Sensors feature a unique proprietary microwave design, also known as Stereo Doppler, that detects the motion of the intruder, and with digital sensitivity control, a 10-position switch adjusts the amount of movement required to initiate an alarm. The PIRAMID Indoor sensors offer false alarm-free performance over a variety of applications. The stereo Doppler technology features two receiving channels that have the ability to eliminate vibration and randomly moving objects as sources of false alarms. Special filtering also facilitates exceptional immunity to birds and small animals.
PIRAMID sensors offer reliable volumetric detection (and protection) in the most extreme environmental conditions and the highest security sites. All models come in a rugged and durable housing offering maximum protection against RFI and EMI interference.
