This new ultra digital wireless technology is the solution to interference problems with wireless monitors. It provides secure video with exceptional image quality and crisp audio. The encrypted frequency hopping technology guarantees privacy and prevents traditional interference from other technology devices such as cordless phones, wireless routers and microwave ovens. The Camera can be placed on a flat surface like a table or a dresser, or wall mounted. The Camera comes with built-in battery packs. Receiver comes with cradle for recharging. The Power Saver Mode turns the display and audio off on the receiver, until the Camera detects noise. Once noise is detected from the camera, the receiver will alert you with the alarm, and will automatically turn on the display and audio. Audio Detection Sensitivity can be adjusted by scrolling up or down on the Camera's Sound Alarm Trigger. The audio detection is so sensitive it can detect the faintest of sounds. The camera image can be displayed as PIP on a TV. This allows the user to monitor the camera, while watching TV. The Out of Range notification message is designed to notify you when the camera and receiver are not able to communicate with a strong signal. This allows for camera placement adjustments to help prevent image loss when actively monitoring. When the camera and receiver can no longer communicate with each other a No Signal message will appear. Audio / Video Out (A/V Out) The A/V Cable plugs into the cradle (or receiver) outputs, and into a TV/VCR or Monitor. This digital monitor is the very latest in Wireless Digital Technology with excellent video quality and audio quality. It comes with a built in stand & belt clip.
