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.
iBaby currently works with iOS devices and provides parents with instant video and audio monitoring of their baby from wherever they are. As long as you're connected to the Internet, either via a Wi-Fi or 3G/4G network, and have the complementary iBaby Monitor app installed, you can pan and tilt the monitor to get a better view, and use the built-in audio feature to speak to your baby and offer gentle shushes if she starts to rouse. There is even a motion and sound detector that will alert you, based on the level of sensitivity you've selected.
Bought this reasonably priced monitor after I dropped the other (very expensive) handheld in the toilet. Don’t ask! Anyhow, this baby monitor works great! Great picture on the monitor. They only thing is - the screen doesn’t shut off after a certain timeframe of being on. And there isn’t an option but to have the screen lit up all night in your bedroom. It’s super bright and I have to turn the screen in another direction away from my face. I do miss being able to redirect the camera with the video monitor buttons like my last one. To reposition camera you have to go into the baby’s room. Another odd thing is... maybe just to me, but I like hearing if my baby moves or repositions himself. And the monitor doesn’t pick that up. It also doesn’t pick up the sound machine (which is set to “rain” and or the humidifier). I only know he is awake if he makes a sound or starts playing with his few toys in the crib.
Gone are the days of silently peeking into the nursery to check on your napping baby and then, whoops, accidentally waking them up (“No, no, please no!”). A baby monitor uses a camera to watch over the crib, while you carry a handheld device that lets you know what’s going on with your child at any given moment, no matter where you are in your home. There are also other monitors that track sleep or breathing either with a clip or sock.
