A baby monitor is a valuable tool for keeping an eye on baby. You can not only hear your baby, you can watch your baby sleep. This Infant Optics monitor has night vision, which allows it to work even in the dark. The receiver screen is 2.4 inches of full color, even in the dark! At 30 frames per second, you will have clear view of your baby’s every move. The technology is amazing for the price. 2.4 Ghz of wireless technology means that you get reception for over 600 feet in the open, and 150 feet in an enclosed area. (If you are at a bar-b-que next door, you can still have your eyes on your baby). Since it uses night vision, there is no reason to turn on the lights when checking on your child. Added bonus, the data being sent to your receiver is encrypted, so you don’t have to be concerned about someone else picking up the visual feed from your baby monitor. The powerful microphone has a voice activation mode… so it only draws power when it’s needed. After 3 minutes of silence, the microphone goes into sleep mode. This baby monitor has only the functions you need, and not a load of extra bells and whistles that will cost you money for things you don’t use. It is easy to use, and looks great.
