The digital receivers, whether a microphone or s camera, are also more sensitive to sound and visuals respectively. One problem of analog baby monitor devices is the fact that there are instances when neighbours can actually tap in to the signal of your baby monitors and listen. With the digital technology, privacy is kept since it broadcasts private signals that only you, the parents, have access to. Video baby monitors make use of cameras instead of just the usual transmitter with microphone device. A camera or a number of cameras are installed in the baby s room and live video feed are transmitted to a TV or LCD receiver. These video devices can either be wired or wireless devices. The most basic application of a wired video baby monitor is to provide live video feed from the room of the baby to the room of the parents. 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. They are usually portable and come with multiple cameras and even night vision. Sensory monitorsdetect the baby s slightest movements even during sleep. The radio transmitter must be positioned 8 to 10 feet away from your baby's crib. Then again, you can always position it closer to the baby for better reception of sounds. The signal picked up by the radio transmitter is then passed on to the portable receiver, which can be carried effortlessly around the house. There have been a lot of reported cases by parents that they are getting signals from the baby units that are not relevant to the baby or the environment. Instead, they receive muffled, indefinable, and sometimes almost inaudible sounds which resemble voices and words coming from a human. When examined by experts, these sounds can t be technically explained. With baby monitors, you can keep track of your baby s even if you are doing something else in the proximity of your house. Types of Baby Monitors Baby monitors have evolved through the years. From the simple transmitter and receiver device, different baby monitors have been developed. Currently, there are two types of baby monitors: video baby monitors and audio baby monitors.
