Unlike the baby monitors off the shelf, professionally installed ones usually make use of high end gadgets in watching over your baby. The Types of Baby Monitors Basically there are two types of baby monitors: audio and video baby monitors. Audio baby monitors only make use of sounds while video baby monitors make use of a camera and transmitter to send video feeds to a LCD receiver. During night time when the lights are already switched off, you can still continue the surveillance of your baby. Low lit environments and dark rooms is not a problem with the help of the night vision feature. Another special feature that some video baby monitor provides is the baby cam feature. With the use of the Internet, parents will be able to keep track of their baby. 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. You can transfer from room to room or while even in the bathroom and still you won t lose track of what is happening to your baby. With the digital technology, privacy is kept since it broadcasts private signals that only you, the parents, have access to. Another dilemma that has plagued analog baby monitors before is the range. There is no total mobility since parents can easily get out of range from the baby unit. But with digital monitors, the range of the devices has been extended making it more possible for the parents to roam around the house without worrying of getting out of range. 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. All they need is a computer with Internet access and voila! Always follow the instructions of the manufacturer religiously so as not to encounter any problems with the device that you purchased. 4) Baby monitors, especially the parents units are very handy and can easily be carried around. Always remember to carry the units with care because they may break. These are just some of the things you can do to resolve interference when using baby monitors in blocks of flats.
