The audio baby monitor receives and sends sound so that the parent could hear the baby from a distance. The video monitor on the other hand works like a tiny TV by having a camera record the baby s movements while the parent could watch on a small screen receiver. And the sensory monitor is a movement detector that alarms the parent when it cannot perceive any movement from the child for more than 20 seconds. The receiver, instead of just having speakers, already has LCD screens installed along with them. Video baby monitors have also taken advantage of the current technology of the Internet. With the video baby monitor installed in the room, parents can access the cameras and view the conditions of their babies even when they are at the office. This is true with wireless baby monitors. The most disadvantageous aspect of these wireless devices is interference. 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. Remember that the base unit of your cordless phone should be switched on last. 3) Purchase a digital baby monitor instead. To make sure that your neighbors will not be able to pick up the sounds transmitted by your baby monitor, buy a digital type as an alternative to the analog version. This way, you can rest assured that the only sounds you'll hear are the ones that have originated from your baby's room. " A solution developed to counter this problem simply states that parents should put the baby monitor as far away as possible from the child without sacrificing the quality of monitoring. This way, exposure to the harmful waves is, if not eliminated, at least minimized. This next issue can be a disadvantage for some people but not for others. This includes wireless phones, cell phones, and routers. 3) Prioritize Your Baby Monitor If it is unavoidable that you use wireless devices other than the baby monitor, make sure that you prioritize your baby monitor. Before switching on any other wireless device, switch your baby monitor first. This will help the device get the best reception.
