Our extensive, independent testing reveals the best - and the worst - baby monitors available to buy.
We unearth the monitors that have the longest battery life and the best signal, and weed out the models where the sound quality is so poor or the picture so fuzzy that you won't be able to tell if your baby needs you or not.
If you're worried about stories you've read about wi-fi baby monitors being hacked, you'll be relieved to hear that we test for security and privacy as well.

The last thing you want is your baby monitor running out of battery when you're in the middle of using it, and you won't want to be annoyed by the constant beep of the battery warning in the middle of the night.

A baby monitor is no use if the sound and/or picture quality aren't good enough to actually use it to monitor. We put the sound and image to the test in a number of ways, so you can have confidence that your monitor will make it clear exactly when your baby needs you.
Our lab experts don't stop at testing the main features, our investigations also check how easy each baby monitor will be to use in your day to day life.
