4 Channel B/W Wireless 2.4GHz Video System

Monitor can be hooked up to a VCR for recording, built-in microphone for audio monitoring, frequency modulation (FM) ensures great picture and sound quality, built-in IR illumination provides images in the darkest location, video function on monitor can be turned off for audio monitoring only, range up to 110yd. View up to four cameras via a single monitor ; manual or auto scan for multiple cameras ; adjustable scan time interval : 4 or 8 seconds. Easy installation and connection, camera sits on a shelf or tabletop, or may be permanently mounted on a wall. Portable system: for the ultimate in portability, the camera and monitor are both mains or battery powered.
Both PAL and NTSC compatible, 2.4GHz eliminates interference and provides superior quality to 900MHz, 433MHz RF, or IR wireless devices, directional high-gain antennas reduce interference and provide superior performance.
