Protech Technologies SDI-76M-HS1 Indoor Motion Sensor, High Security, 75' x 75', Fluorescent Filter Module

The Protech SDI-76M-HS PIRAMID is an Ultra High Security indoor intrusion sensor engineered to meet the stringent requirements of U.S. government and military agencies.

The HS Series enhances the standard PIRAMID dual-technology platform by integrating multiple special high-security features and upgraded supervision elements designed for mission-critical detection.

Using the PIRAMID architecture, the SDI-76M-HS combines Stereo Doppler microwave detection with a dual-element passive infrared sensor, providing true dual-technology discrimination. The M-version HS sensors include a field-configurable And Gate / Or Gate switch, allowing the installer to choose between maximum false-alarm rejection (AND) or maximum sensitivity (OR), depending on security protocol and room geometry.

The HS platform delivers a Probability of Detection greater than 0.95 with a very low NAR/FAR, making it suitable for environments requiring elevated trust and continuous monitoring.
