Range The size of your house, as well as the distance of the nursery from your bedroom or other vital parts of your home need to be taken into consideration. If you live in a small apartment or if your baby's room is only a couple of rooms away, then virtually any type of baby monitor will suffice. On the other hand, parents who own bigger houses or live in multi-story residences require a device that has a longer range. Wireless baby monitors are usually equipped with switches that allow parents to change frequencies easily. The next option in fixing interference is by properly placing the baby monitor, both the baby s and the parent s units, in the proper location. What does it mean by proper location? It means that the baby monitors should be placed as far away as possible from other wireless devices. Baby Monitors Basically, baby monitors are devices that parents can use to be able to observe their baby even if they are not in the same room. The most simple baby monitors make use of a simplex transmitter and receiver system. In the baby s room, a transmitter device with microphone is installed while the parents have a receiver device with a speaker. 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. Fortunately, there are ways to solve these kinds of problems like adjusting channels or changing frequencies. 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. In the case of using baby monitors in blocks of flats with a dozen or more tenants, the devices may encounter several problems which include interference. Instead of just being able to hear your baby, you can now actually talk back to him or her. 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.
