Our compact, handheld video monitoring system lets you keep an eye on baby from anywhere in your home. It allows a close up angle or an entire view of the nursery and features advanced 900 MHz technology for crisp, clear transmission from distances up to 300 feet away. Special Night Vision with infrared technology lets you monitor baby without disturbing slumber, even in total darkness. Plus the camera automatically awakens from sleep mode when it hears sound above a level that you set. Additional features include up to two camera monitoring with the same receiver, AC and battery operation (each uses 4 AA batteries, not included) and AV cable for connection to TVs or VCRs.
