The Philips baby cam offers extra reassurance while your baby is sleeping. This wireless colour baby camera and monitor lets you watch your little one on your own TV and make precious home videos without disturbing your child using your own DVD or VCR. This system will grow with your child and this means you can keep your eye on your child while they are playing in another room. If the signal is interrupted, an alarm will sound and with a choice of channels, there is no need to worry about interference. However, one thing I would mention is be careful if you have other wireless devices this could cause interference on the monitor.
