So to aid you with your wanting to watch your baby 24 hours a day, 7 days a week, you may want to consider using wireless baby monitors night and day. What are Baby Monitors? Baby monitors are devices, either audio or video, that can help you check up on your baby even if you are not physically present with him or her. Having more than one receiver makes it possible for both parents to keep a closer eye on their little bundle of joy. You may also keep the second receiver on stand by in case your main one runs out of battery juice. In addition, an extra receiver may also come in handy especially if you have a tendency to lose things like phones, remote controls, etc. Although this can be an addition cost, the price you pay in order to take pleasure in its portability is certainly worth it. What are the disadvantages of Baby Monitors? First and foremost, baby monitors work more efficiently between ground floor and first floor areas. However, if your home is made of thick concrete walls or has aluminum siding, then this can terribly decrease the strength of the transmitted signal. What to Look For in a Baby Monitor Clarity of the Reception (whether audio or video) and less static is always a good quality for the baby monitor to become effective in child safety. This allows you to clearly hear or see the activities of the child better. A good monitor must always be handy. A compact and portable monitor will easily provide you with comfort as you carry it around the vicinity. This holds true with the devices called baby monitors which are used by parents to watch over their babies. But these devices all have their limitations.

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. Phillips is one of these manufacturing companies that claim that the level of electro-smog released by their gadgets are 10,000 times lower from the safety norms that are accepted internationally.
