A baby monitor is an essential purchase for expectant parents, as it will give you the peace of mind of being able to check on your sleeping baby wherever you are in your home Unfortunately, these monitors are the kind of device which you are unlikely to have any experience of until the time comes when you need one, and it can be difficult to know which type to buy 

There are three basic kinds of monitor: audio, video, and movement or breathing 

The audio monitor is the most popular kind, and at its most basic consists of a transmitter that you place in your baby's nursery, and a receiver that lets you 'listen in', alerting you if your baby starts to cry or otherwise shows signs of waking The very cheapest modules will have a fixed receiver that needs to be plugged into a wall socket for power, but most models nowadays have a rechargable mobile receiver which you can carry from room to room, or even outside so long as you stay in range 

The range of your monitor system will depend on a number of factors, including the construction of your home - thicker walls will reduce the range - and any sources of interference such as neighbouring monitor systems, computer wireless networks, and even microwave ovens with some models 

Interference is less of a problem these days, as most models will now let you select from a range of channels to operate on, so if you do encounter interference problems, you can switch to a new channel to hopefully clear things up Some units only feature two or four channels which you have to manually select, while the more advanced designs now have hundreds of channels which will be selected automatically to minimize interference in the current conditions
