Multi-room Monitoring A good number of baby monitors only have one radio transmitter and one or more portable receivers that make it possible for parents to listen in on their babies all day and all night long. If you prefer to have one radio transmitter in every room, there are actually a smaller number of choices. Almost all types of monitors, whether audio or video, can be wired or wireless. It all comes down to budget and preference. The Advantages of Wireless Baby Monitors As have been mentioned, the most advantageous feature of a wireless baby monitor is mobility. Imagine being able to move around the house doing all the necessary chores without losing the ability to watch over the baby. If you intend to use the video monitor at only one location, then you may opt to use the wired version. But if you intend to use the video monitor in different places all over the house then it would be a good idea to avail of the wireless devices. Take note though that wireless video monitors also have their limitations. Even if the lights in the baby s room are switched off, with the help of the night vision baby monitors, you can easily see your baby. They will work perfectly well in low light environment and even in total darkness. Since babies are still quite photo or light sensitive, switching off the lights will greatly benefit them. Basically, a baby monitor, also known as a baby alarm, is a device that can be used to monitor your children or babies even if they are located in a separate room than yours. It is a simplex transmitter and receiver system that can be used to remotely listen for different noises made by your kids and babies. A light alarm that activates whenever it picks up sound is always a good feature of the gadget. This becomes very useful in instances wherein you might be preoccupied with loud noises in the area such as the sound of the television or vacuum. This will at least keep you alert and aware if the baby is making noises.
