LCD or Liquid Crystal Display are the choice of manufacturers in video baby monitors since it is light, and is the best mobility wise compared to CRT devices. Baby monitors that use live video feeds may only be of two things: wired or wireless. Wireless devices are convenient and are the good partners for video baby monitors that use LCD screens as the parents unit. You and your next-door neighbors may utilize similar channels and wind up hearing noises from each other's homes. Cordless telephones may also interfere with your signal. In case interference is a big issue for you, you can always look for something that utilizes the so-called no-interference technology or has additional security features. Wireless interference may come as irksome sounds, static sounds or buzzing sounds. In video monitors, interference may come in the form of fuzzy or static reception. These wireless interferences are usually caused by other wireless devices around the house like the wireless phone or a router. Other wireless baby monitors from your neighbor s house can also cause interference. There are even some devices that will let you send commands to the baby s device to play different music to hush him or her back to sleep. Both types of baby monitors, audio and video, can either be wired or wireless. The wireless devices may, in some cases, be more advantageous than the wired devices since you will be able to go anywhere anytime for as long as both devices are within range. These solutions are often in the form of gadgets that have the potential of making life a lot easier for the middle-class, working parents. Then again, if you live in an apartment building with a dozen or more tenants, you could come across a number of additional setbacks every time you try to use a wireless device. Because of the huge possibility of the electromagnetic energy used in the digital technology of modern baby monitors, a lot of parents are fearful for the safety of their child. But on the other hand, manufacturing companies of these digital monitors claim that the amount of radiation that their baby monitors emit are at levels that do not pose serious danger to children.
