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. But as much as you would like to always stay beside your child, it is inevitable that there are other things that also need to be taken care of. Doing two things at the same time, watching over your baby and doing your other household chores, seem quite impossible. So what do you do? You can use baby video monitors. But as long as one knows how to set certain prevention methods such as placing the monitor at a safe distance from the baby (at least one meter) and not adding a lot of other appliances inside the baby s room such as televisions or computers, then much harm on the child s health can greatly be prevented. 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. Both modes have their own advantages and disadvantages. But as of today, parents usually prefer the wireless devices over wired ones for reasons of mobility. With wireless devices, parents can go anywhere around the house while still being able to keep tabs over their babies. The only setbacks of wireless baby monitors are that it can be more expensive to wired devices and they are also prone to interference. This feature allows you to immediately know that something's going on without even hearing the sounds. Double Receiver Opting for baby monitors with two receivers is an excellent idea; that is, if you don t mind shelling out more money than you're supposed to. At present, there are certain brands on the market that offer buyers with an option to buy additional receivers.
