Bottom line

The Angelcare AC401 Deluxe Movement and Sound Monitor includes a sensor pad that sounds an alarm after 20 seconds if motion isn't detected. It also has a traditional audio monitor that offers best-in-class range, according to experts. But getting the sensor pad installed correctly makes this monitor a bear to set up, and false alarms can frazzle parents' nerves, reviewers warn.


Best-in-class range and excellent clarity. Experts say the Angelcare AC401 Deluxe Movement and Sound Monitor's range is as good as or better than top audio monitors. Clarity is marginally lower than other highly rated sound monitors, and eight channels help keep interference to a minimum. Users say the movement sensor is effective as long as the baby is directly on top, but older babies may roll away and trigger false alarms. The Deluxe Plus model (Est. $160) includes two pads for better coverage. Some say the monitor detects ceiling fans and other ambient movements, reducing its sensitivity to the baby. The motion alarm sounds in the nursery, which can wake a sleeping baby during a false alarm.

Ease of use

Time-consuming setup. Testers say the Angelcare AC401 Deluxe Movement and Sound Monitor takes time to set up. There must be a stable surface between the crib mattress and base, and some cribs require the addition of a more solid crib base. Parents may experience false alarms before they get the motion-sensitivity setting right. The monitor can run on A/C power or rechargeable batteries. Several parents are unimpressed with battery life, but the monitor fared well in expert tests in that category. Parents can choose sound or vibration alerts, and the parent unit has signal lights. When using the motion sensor, parents can choose silent or ticking mode. There is also voice activation to minimize white noise.

Lifestyle features

Multiple features win praise, but beware of recalled units. The Angelcare AC401 Deluxe Movement and Sound Monitor has a number of extras, including a pager, temperature tracker, night-light and belt clips on the two included parent units. Unlike motion sensors that don't monitor for sound, the Angelcare has a longer usable life for most families, who likely will stop using a motion-only monitor when baby is between 6 and 12 months old. The nursery units are wired, including the sensor pad. In November 2013, Angelcare recalled 600,000 monitors after two infants pulled the sensor-pad cords into their cribs and strangled themselves. The company has provided rigid cord covers to remedy the problem.
