A baby monitor is especially useful when your little one is still very young. By means of the receiver, you will be able to monitor awakenings in the middle of the night. In this way, you will know when your baby needs feeding, a diaper change or, perhaps, your mere presence and the comfort of your touch. A great example of this is the video baby monitor. Video baby monitors make use of cameras instead of just the usual transmitter with microphone device. 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. For example, if you want to leave your baby in the living room for a while, you can get the device from the baby s room and transfer it to the living room without going through the difficulty of moving the wires. The Disadvantages of Wireless Baby Monitors If such devices have advantages, then it is possible that they also have disadvantages. 1) Signals coming from wireless devices usually clash with other signals from other wireless devices running on the same frequency. When this clashing occurs, wireless interference occurs. So to avoid interference, change the frequency of your baby monitor every once in a while and make sure that the frequency you use does not clash with frequencies of other devices. These devices have enough electricity in them to cause shock. 3) Baby monitors always come with a manual or an instruction booklet. Always follow the instructions of the manufacturer religiously so as not to encounter any problems with the device that you purchased. 4) Baby monitors, especially the parents units are very handy and can easily be carried around. Wireless Baby Monitors can be used to either audio or video baby monitors.
