The Night Vision Security Enhancer, Night VISER, is an infrared illuminator and motion-sensing system from ARA Security Systems of Albuquerque, New Mexico. The portable, rugged, rapidly deployable, wireless system works with night-vision goggles. Four disposable nodes are linked to a hand-held remote via a radio-frequency signal. When the motion sensor is triggered, a signal is sent indicating a breach, and the illuminator comes on to highlight the threat. At night, intruders can’t see the light unless they are wearing night-vision goggles. In day mode, the infrared is turned off, and operators are notified by radio.
