Wireless systems use radio frequencies that are designated by governments for unlicensed use. For example, in North America frequencies near 49 MHz, 902 MHz or 2.4 GHz are available. While these frequencies are not assigned to powerful television or radio broadcasting transmitters, interference from other wireless devices such as cordless telephones, wireless toys, computer wireless networks, radar, Smart Power Meters and microwave ovens is possible.
Baby monitors help you keep a watchful eye on your little one when they are asleep or awake ÃÂ they offer peace of mind and are a Baby Registry favorite. Browse our selection to find the solution that's right for your family ÃÂ compare a baby monitor with a camera, one that may be operated using a smart device, models which offer twoÃÂway communication, the ability to pan, zoom, tilt and enjoy wide angle views, units with night vision capabilities and more. Video baby monitors make it easy for you to keep tabs on your child whether you are in another room or enjoying a night out and have a sitter at home; more sophisticated units allow you to monitor multiple children in different rooms. WiFi baby monitors let you stay connected via a secure connection to your smartphone, tablet or computer so you can log in and check on your baby from anywhere. Audio monitors give you the reassurance that your child is resting peacefully so you can move around without missing a peep.
Some audio/video monitors filter out "normal" sounds and motions. The receiver is supposed to turn on only when your baby makes an unusual motion or sound, such as crying or rolling over when he's waking up from a nap. This feature is designed to extend battery life, although the receiver should be docked for overnight monitoring to keep the battery charged. We haven't tested any models with this feature, so we don't know how well it works.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
