Dual technology indoor sensors
RANGE : Depending on the model and application, the PIRAMID Indoor series range from SDI-76 which is 75 ft. x 75 ft. (22mx22m) and 100 ft. x 10 ft. (30mx3m) for the SDI-77 model; 75 ft. x 75 ft. (22mx22m) for the Ultra High Security versions featuring special requirements of the US military and government agencies and a Microwave only version with a 50 ft. x 50 ft. (15mx15m) and 100 ft. x 60 ft. (30mx18m) for the SDI-76MW AND SDI-77MW models respectively
RELIABILITY : Like its outdoor family members, 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
PERFORMANCE : The PIRAMID Indoor models provide exceptional performance in all environments and customization depending on application
Building upon the reliability and success of PROTECH’s Outdoor PIRAMID Dual Technology family of sensors, a range of sensors also exists for indoor security.
The PIRAMID XL Indoor, PIRAMID Indoor Microwave and PIRAMID XL High Security sensors are all based on the stereo Doppler technology.
PIRAMID Indoor sensors feature a unique proprietary microwave design (termed 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.
Special filtering 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.
