Interlogix motion sensors have the most advanced and sophisticated optics in the security industry. The EV1116 and EV1116AM are powerful 16m volumetric PIRs that feature the latest optical mirror technology of the 1000 series. To increase detection coverage, the 1000 series sensors use the 3Brid orthogonal curtain design. This is a horizontal mirror structure that produces curtains with vertical orientation to detect infrared. This orthogonal invention is the key in adding curtains to the mirror without sacrificing signal strength, nor increasing the size of the sensor. The EV1116/AM produces 11 continuous curtains at 16m distance.

The EV1000AM series incorporates industry leading anti-masking via active infrared technology. This advanced technology protects from the most advanced sabotage attempts including device penetration as well as wood, metals, ceramics, cardboard, paper, glass, PVC, spray-paint, lubricants and many other masking substances. The addition of dynamic pyro and circuitry diagnostics further ensure that the devices have not been tampered and are always in their correct operational state.
