The Angelcare movement and sound monitor deluxe plus offers both sound and movement monitoring in one device. With a range of up 820 feet and eight channels to minimize interference, the monitor offers continuous or voice activated sound transmission and will sound an alarm when no movement is detected for 20 seconds. For convenience, the monitor features a temperature display and sound and movement indicator lights. The deluxe plus system includes two parent units and two "under the mattress" sensor pads.
From the Manufacturer
Mom and dad sleep tight too, knowing their child has drifted safely off to dreamland thanks to this upgraded version of the Angelcare AC401, our best, most-advanced baby movement & sound monitor. It comes with 2 Sensor Pad movement detectors for added reassurance and 2 state-of-the-art Parent Units – so mom and dad can both keep an eye on the nursery from the kitchen, garage, home office, family room or anywhere else in the home. Features an easy to find locator too. IMPORTANT: The AC401 Deluxe Plus Movement & Sound Monitor IS DESIGNED FOR ONE CHILD ONLY because the Sensor Pads are connected to the same circuit. Therefore the alarm will not sound if movement is detected on just one of the Sensor Pads. *Note: The Sensor Pad can be used with a regulatory standard baby mattress, whatever the size or thickness. However, it cannot be used with memory foam mattresses, dual sided, mattresses with a hollow frame or Purflo mattresses.
