Multi-room Monitoring A good number of baby monitors only have one radio transmitter and one or more portable receivers that make it possible for parents to listen in on their babies all day and all night long. If you prefer to have one radio transmitter in every room, there are actually a smaller number of choices. A camera or a number of cameras are installed in the baby s room and live video feed are transmitted to a TV or LCD receiver. These video devices can either be wired or wireless devices. The most basic application of a wired video baby monitor is to provide live video feed from the room of the baby to the room of the parents. However, there are also baby monitors that are installed by professionals. Unlike the baby monitors off the shelf, professionally installed ones usually make use of high end gadgets in watching over your baby. The Types of Baby Monitors Basically there are two types of baby monitors: audio and video baby monitors. From the simple transmitter and receiver device, different baby monitors have been developed. Currently, there are two types of baby monitors: video baby monitors and audio baby monitors. Video baby monitors, as the name implies, use video footages for overseeing events in the room where the baby is located. Luckily, there are several ways on how to, if not eliminate, at least minimize the existence of interference. On top of the list is changing the channel or frequency of your baby monitor. If two devices are running on the same frequency, it will cause interference. So to prevent this from happening, you should try to change the frequency of either device. As a result of sticking to this course of action, the monitor gets to capture the initial accessible signal that will give out the most excellent reception and not impinge on your other wireless gadgets in the process. 5. Consider purchasing a digital baby monitor. If you want to ensure that your next-door neighbors won't be able to pick up the transmitted sounds from your baby monitor, purchase a digital version instead of an analog one.
