Angelcare Movement and Sound Monitor AC401

Product information

The Angelcare Movement and Sound 2-in-1 monitor detects your baby’s sound and movement, even the slightest breathing movement. If your baby is still for 20 seconds, you'll be alerted.

Complete with variable sensitivity settings and a unique combination of 8 channels and 2 frequencies, the SensorPad emits crystal clear transmission within a 250m range. Both units are mains or battery operated and the rechargeable parent unit is portable for added convenience. Simply clip the small portable parent unit to your belt and monitor your baby on-the-go.

Features of the Angelcare Movement and Sound Monitor AC401:

  • Under-the-mattress SensorPad: The SensorPad monitors all your baby’s movements, even the slightest breathing movements. An alarm will sound if no movement has been detected for 20 seconds. Features variable sensitivity settings. Works on all mattresses except memory foam mattresses.
  • Portable rechargeable Parent Unit: Clip the small portable Parent Unit to your belt and monitor your baby on the go. Battery unit lasts for up to 8 hours, when fully charged.
  • Crystal clear transmission: Enjoy crystal clear sound transmission and security with the unique combination of 8 channels and 2 frequencies.
  • Out of range indicator: With a 250m range, you can go further without losing touch. Alarm sounds if connectivity is broken.
  • Volume control and vibration alert: Adjust the sound levels to suit you and monitor your baby even with the sound off.
  • Temperature display and control: Monitors and shows the temperature in baby’s room with the temperature indicator on the Parent Unit. Alarm sounds if the temperature is too high or low.
  • Full colour digital display: The colour LCD screen on the Parent Unit clearly displays a number of monitoring features, so even if the sound is off you’ll know what’s going on.
  • Nightlight: The halo on the Nursery Unit acts as a soothing nightlight and allows you to check your baby with minimal disruption.
  • Hold and mute: If, for example, you need to feed or change your baby the sound and movement alarm can be temporarily deactivated.
  • Continuous sound monitoring: The Angelcare system can be set to continuous or voice-activated sound monitoring. Microphone sensitivity is adjustable so you can hear all sounds in baby’s room or just when baby cries.

Please follow the instruction manual when you install this monitor. Place the nursery unit at least 3 feet away from the cot and make sure the sensor pad cord is well out of baby's reach by wrapping it around the leg of the cot and securing it with cable ties.

Q & As

Angelcare Movement and Sound Monitor AC401 4.4 5 31 31
Anxiety preventer Great product and a great anxiety preventer. Put's you at peace of mind if worried out cot death and child temperature. Senor pad could be larger or have the ability to daisy chain an additional pad for larger cots. 27 December 2014
Such peace of good The unit works brilliantly. We have had it set of a few times (in 14mths) but mainly due to the sensor pad being positioned badly (in the travel cot) OR on a couple of occasions our son has been curled up right in the corner of the cot - and I think asleep VERY soundly....BUT on the plus side when the alarm has gone off...he has we are assured that all is ok. Definitely worth the money. We bought this when it was twice the current price and I don't regret it at all. 26 December 2014
Peace of mind Easy to setup, easy to use and provides so much peace of mind. We have twins and have bought two (obviously for separate cots). They provide us with the ability to sleep soundly in the knowledge that we will be alerted to any issues. Just remember to switch them off when you pick up the child out of the cot. 09 December 2014
Piece of mind Having this for our newborn is piece of mind for us during the day and night when she is at sleep. 08 July 2014
Good but with flaws Overall pleased with the monitor, which was bought to replace a sound only monitor. The movement mat really gives me peace of mind and is working well even though my son has taken to rolling right to the side of the cot. However there are a couple of design flaws that really annoy me. The biggest being that the sound on the parent unit switches off after a period of quiet - although it comes back on automatically once a noise is detected, it's after the noise happens so if your baby just gives a little short sleep noise then you won't hear that itself, you will just be aware that a noise has happened because the monitor starts transmitting sound again. Personally I would have preferred a constant sound transmission, or at least for the automatic shut off to be an optional feature. Also there's no clock on the monitor so when I'm woken in the night I can't immediately see the time to consider what it is my baby likely wants - a feed or just to be resettled etc. Once my son is a bit older and we don't feel the need to monitor his movement, we will switch back to our old sound only monitor but for now I'm definitely pleased we're using it. 23 April 2014
Product as expected Bought this product based on the reviews and awards for my newborn. He has not yet slept in his cot to use it but it was easy to set up and install. Hopefully it'll prove to be as good as all the reviews. 08 April 2014
customer service the aftercare is brilliant I dropped monitor and cracked face and I got replacement cover posted and delivered in two days 03 February 2014
Great baby monitor I bought this monitor for my first baby and have been delighted with it. It provides so much peace of mind, and definitely works (as the alarm has gone off whenever I have lifted my baby out of his crib and forgotten to switch it off). The portable monitor allows you to keep an ear on your baby all around the house. I'd recommend it to anyone. 20 November 2013
