Video monitorsallow you to see and hear your child by combining sound and video just like miniature TV sets. They use a small camera either mounted on the wall, table or crib to transmit the images into the LCD display. They are usually portable and come with multiple cameras and even night vision. Sensory monitorsdetect the baby s slightest movements even during sleep. What is the difference between the two-way monitor and one-way monitor? One-way monitors from the name itself, basically only transmit sound through a single channel wherein parents can hear the sounds that their baby makes from the other end. However, the much-improved two-way monitors can allow parents to talk back to their child with their own portable transmitter. A typical baby monitor set consists of two parts: a radio transmitter and a portable receiver. The radio transmitter must be positioned 8 to 10 feet away from your baby's crib. Then again, you can always position it closer to the baby for better reception of sounds. The signal picked up by the radio transmitter is then passed on to the portable receiver, which can be carried effortlessly around the house. The better the technology, the better monitoring will be. Disadvantages of Using Professional Wireless Baby Monitors LCD The biggest disadvantage of using professional wireless baby monitors is its cost. Compared to using off the shelf gadgets, professional ones will cost way much higher. This is expected of course since you will be given the best possible baby monitoring system they can provide. Because of this trend, as well as the necessity for better portability, a good number of modern baby monitors are currently equipped with ultra-small receivers. Most baby monitors these days also come with receivers that have belt clips. This feature allows parents to carry the device around without much effort. By simply positioning one radio transmitter in each room, you can listen to the sounds coming from your baby's room even if you're busy with house chores or other stuff. Then again, this added capability comes with a number of drawbacks. The baby monitors could interfere with each other. For that reason, you need to make sure that they are set in different frequency bands; otherwise, you will only be able to hear irritating electronic screeches.
