Luckily, technology has made it possible for manufacturers to create baby monitors for deaf people. A regular baby monitor alerts parents each time their little bundles of joy need attention. The device usually functions by means of transmitting sound from the baby's room to a portable receiver that can be conveniently placed inside a pocket or strapped around the waist. 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. But if you do have the money for it then by all means, then go ahead and purchase one. 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. Disadvantages of Digital Baby Monitors Digital baby monitors do also have their fair share of disadvantages. Every now and then, your baby monitor may compete with these wireless devices for better signal reception. For that reason, it is better to purchase one that features a channel adjustment capability. This way, you can change frequency bands every time you encounter interference problems. Of course, you also need to factor in the cost of buying a baby monitor. Some models even have extra capabilities including a video monitoring feature and an option that lets your baby hear your comforting voice. Factors To Consider When Buying A Baby Monitor Low-battery Indicator As much as possible, you should purchase a baby monitor that has a low-battery indicator. In this way, you will be alerted whenever your batteries need replacement. Another advantage is that the digital models do not have as much static and they give a clearer sound quality so you can hear your baby better. Video monitorsallow you to see and hear your child by combining sound and video just like miniature TV sets. They use a small camera either mounted on the wall, table or crib to transmit the images into the LCD display.
