Heart Beat Monitor This feature is a must for the device that you will choose since no apnea monitor is 100 percent accurate in detecting cessation of breathing. This will serve as a backup in case the apnea monitor fails to detect apnea because it will also manifest in the heart rate of the baby. Another must have feature is a remote alarm. Resolving Wireless Baby Monitor Interference Baby monitors are devices that help parents watch over their babies. But no matter how these gadgets may seem to help, there are times when they become annoying especially when you encounter interferences. Baby monitors, specifically wireless ones, may experience a lot of interferences especially when you live in flats with short proximity from other tenants. The Different Types of Baby Monitors Our children are our most valuable possessions. If only it was possible to be able to watch over them 24 hours a day, 7 days a week, then you would. This is most especially true when it comes to babies since they are dependent on their parents with everything that they do. A smaller house or apartment might not need as much range especially if one lives in an area where there may be a lot of interference such as cell phones and other monitors that could disrupt the signals. But it is also important to consider the user s activity, especially if work might require him or her to be of farther distance from the child. You should at least get a hold of answers for questions such as: "Will I need to recharge it frequently?" Interference Since a baby monitor is basically a wireless device, it is highly possible to experience interference with the signal. You and your next-door neighbors may utilize similar channels and wind up hearing noises from each other's homes. For example, if you want to leave your baby in the living room for a while, you can get the device from the baby s room and transfer it to the living room without going through the difficulty of moving the wires. The Disadvantages of Wireless Baby Monitors If such devices have advantages, then it is possible that they also have disadvantages.
