With the on-camera technology of analyzing person and vehicle shapes, RLC-523WA offers accurate detections, and thus greatly reduces the false alarms on trivial objects’ movements. Once an intruder is detected, the camera’s spotlights and siren will be triggered or manually activated to warn off the would-be criminal. Built-in mic & speaker allow you to listen and talk back to whoever the camera catches in real time. With 360° pan & 90° tilt, this PTZ camera allows you to view your world from every angle and can follow the moving person automatically. RLC-523WA provides you with a clearer visual quality & smoother live viewing experience. RLC-523WA with infrared LEDs provides 190ft IR night vision & its spotlights ensure color night vision. Its motorized varifocal lens provides a wide viewing angle, and its 5X optical zoom allows you to zoom in for astonishing details or zoom out for maximum coverage. RLC-523WA supports both 2.4 GHz and 5 GHz (5.8 GHz) frequencies to ensure better performance for camera networking.
