What are EVPs EVP is short for the term Electronic Voice Phenomenon. EVPs pertain to sounds or voices that are allegedly coming from beyond the grave. In the world of the ghost hunters, EVPs are voice recordings that are sent by ghosts or souls that have not moved on. These are sometimes used to prove that there really is life after death. 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. The high-end versions can cost as much as $300 dollars or more. Heart Beat Monitor This feature is a must for the device that you will choose since no apnea monitor is 100 percent accurate in detecting cessation of breathing. This will serve as a backup in case the apnea monitor fails to detect apnea because it will also manifest in the heart rate of the baby. Another must have feature is a remote alarm. This is one advantage of going pro. Another advantage is that there is usually customer support that will be willing to help you in case you encounter any problems. Just a few presses on the dial pad of the phone and you will right away be presented with several solutions to the problem you are experiencing. These things will not only serve as your guide, they will also help you pick out the best type or brand for your little one. Range The size of your house, as well as the distance of the nursery from your bedroom or other vital parts of your home need to be taken into consideration. If you live in a small apartment or if your baby's room is only a couple of rooms away, then virtually any type of baby monitor will suffice. Some doting parents also make use of this feature to calm their babies down by talking to them over the baby monitor. Also, when your child is old enough to speak, you can surely have chats by means of this nifty device. Other Fun Features Newer models of baby monitors now come with a number of fun attributes.
