This wireless outdoor security camera features phase shifting technology to eliminate interference from other 2.4 GHz devices allowing for further distance, more channels and cleaner video. Line of sight wireless transmission distance is over 1200 feet. Also since the transmitter is paired with your receiver your privacy is assured. The video is encoded/decoded using MPEG 4 compression for 720 x 480 resolution.
The DGT-W1 also comes with an audio microphone located in the power cable so you can also hear what is taking place on the video wirelessly. The DGT-W1 provides full color images during the day and automatically switches to B/W at night, with its 24 infrared LEDs the night vision range is 25 to 30 feet. If longer night vision distance is needed an infrared illuminator can be used along side the camera.
Multiple camera and receiver pairs can be used in the same area without interference due to the phase shifting technology. The digital receiver can be plugged into a TV for simply viewing the images or plugged into a VCR or digital video recorder for recording the images.
