Since babies are still quite photo or light sensitive, switching off the lights will greatly benefit them. And with you having a video baby monitor with night vision capability, will still be at ease since you will still be able to see your baby clearly on your monitor. Wireless Baby Monitors Baby monitors can be wireless or wired. It is more important when you live in a flat where there are a lot of people and strangers can easily come and go. 2) Just like with any electronic device, do not let your baby monitor, either the transmitter or receiver, get in contact with water. These devices have enough electricity in them to cause shock. From time to time, their receivers are able to pick up signals from their neighbors' wireless devices baby monitors included. Because of these occurrences, a lot of people have made it a point not to mention any private or confidential information while the baby monitor is switched on. Interference with cordless phones and wireless routers is also a common problem. 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. After that you can switch on all other devices but you should always have the cordless phone switched on last. Another way to fix interference issues is by using digital baby monitors instead of analog ones. The latest digital technology has incorporated some fixes to solve interferences. The only setback with this solution is that it may cost you a little bit more. One-way monitors from the name itself, basically only transmit sound through a single channel wherein parents can hear the sounds that their baby makes from the other end. However, the much-improved two-way monitors can allow parents to talk back to their child with their own portable transmitter. Parents who have children with separation anxiety often prefer this type of monitor, as hearing a familiar voice could usually calm the child.
