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. The major set-back of this variety is the tendency of other receivers picking up the same signal that your monitor transmits, thus less privacy and disturbances are possible. On the other hand, the digital model may cost a little more but it provides more privacy and usually has a wider range of reception than analog. However, the growing concern of many is whether these hi-tech gadgets can be considered safe for our health, especially in gadgets such as baby monitors that are usually placed in such a close distance to children. A lot of parents nowadays fear that if they use a digital monitor to help them keep watch of their child, they might be exposing their offspring to too much of electromagnetic radiation and this may cause significant damage to the child s nervous system. Mobile baby monitors are examples of such useful devices that make parenthood more manageable than you would expect, especially if you're a single mom or dad. What is a Mobile Baby Monitor? In essence, a mobile baby monitor is a radio transmitter coupled with a receiver. The set is synchronized to a predetermined frequency band that gives off a frequency modulation (FM) signal once it is switched on. Unfortunately, such instances could take place quite often if you live in a flat with very close (as in proximity) next-door neighbors. There are actually a number of ways to get rid or avoid interference issues when using baby monitors inside an apartment building. Here are some of them: 1) Change the frequency band. 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. And with you having a video baby monitor with night vision capability, will still be at ease since you will still be able to see your baby clearly on your monitor.
