Analog Video Monitors for Babies

This is a continuous process that, in its essence, breaks the sound and video into smaller parts and then puts it back together.

The cross signal is what that travels between the baby monitor and its receivers can be picked up by other people who use the same or similar baby monitors. In general, it is a problem for people in densely populated areas, such as urban homes and apartment buildings.

If you consider using an analog system it may be worth talking to neighbors with infants and toddlers to see if they use the same model.

Digital Monitors
