Sound monitors
Sound monitors work through radio waves and have a reception distance of between 60 and
500 metres.. They have two units: one unit is positioned close to the baby to detect any
sounds it makes, the other is positioned beside you for monitoring. The units are either
mains or battery operated.
Mains-operated monitors are the simplest and cheapest - but both you and your baby must
be positioned near a plug which limits their flexibility. They are ideal if you spend most
of your time when youre away from the baby in one room, or for monitoring the baby
at night if your bedrooms are some distance apart. They are not suitable if you wish to
monitor the baby while out in the garden or while moving from room to room.
Battery-operated monitors are entirely portable. Some come with rechargeable batteries,
others with adapters for mains use. Rechargeable units save the expense and fuss of
batteries but need to be maintained. Check that the monitor can be used while recharging.
Adapters restrict the mobility of the monitor but save on batteries.
Features to look for
- A moving lights display. This allows you to mute your babys sounds but still
receive an indication that he is becoming distressed.
- A choice of two channels. This can help improve transmission and may be essential if you
live in a flat or terraced house where you may pick up interference from a
neighbours unit
- A volume control
- A night light on the baby unit
- A low power warning signal
- A stand
- A belt clip on the parent unit. Particularly useful if you are going to be moving around
from room to room or out in the garden
- Rechargeable batteries
- An adapter, so that a battery-operated unit can be used on the mains
A sound and vision monitor allows you to watch your baby on a black and white portable
screen as well as hear him. Using infra-red technology and a small camera, the system
allows you to see the baby even when he is sleeping in a darkened room. These monitors are
expensive (at least £300) but can also be used for other domestic security purposes. Less
expensive vision monitors can be bought for use in conjunction with your own television
and video.
