What affects the range of your baby monitor?

You'll never be able to reach the maximum indicated range of a baby monitor. That's because the manufacturer measures this in an unrealistic situation without any interference, such as a room without furniture and walls or an open field. The range of DECT baby monitors, analogue baby monitors, and digital baby monitors is about 50m indoors. PMR baby monitors have a larger range, from 500m up to 2km. WiFi and dual mode baby monitors have the largest range. It's unlimited as long as you have a strong WiFi signal.

Thick concrete walls affect the range of a baby monitor. Do you live in a newly-built house or in an apartment complex? Those are usually made with reinforced concrete, so the range of the baby monitor won't be as large as indicated on the box in that case. The signal will also be worse on a different floor. A WiFi baby monitor doesn't have this problem. You may need a WiFi extender to get a stable connection on every floor.

Newly-built houses are usually well-insulated with wall insulation and triple glazing, for example. The better the insulation of your house, the more it affects the range of your baby monitor. If you live in a well-insulated house, it's better to choose a WiFi or dual mode baby monitor. With a stable WiFi connection, these provide unlimited range. This way, you can be sure that you hear your child when you're on a different floor or enjoying the sun in the back of the garden.

In addition to concrete walls and the insulation, other signals also affect the range. It could be a router close to the nursery, the microwave, or your neighbor's devices. Analogue baby monitors are affected by this the most. Heating up something in the microwave could cause interferences in the sound. Are there many users on the WiFi network? A WiFi or dual mode baby monitor can also be affected by that.
