The Problem
A lot of baby monitor on the market these days are using the 2.4GHz or 5.6Ghz unlicensed spectrum. What’s that you say? Well think of it this way, all wireless devices (including your mobile phone, free-to-air television, radio, 2-way radio etc…) use the same kind of technology: radio waves. The government leases the different frequencies to different groups based on what they want to use it for and how much money they pay.
That leaves the rest of us with our Cordless Phones, Home WiFi, Wireless Doorbells and you guessed it, Baby Monitors, with a small range of frequencies to use that don’t require a license. This means that many devices you buy are competing for the airwaves.
Many devices are now digital, so you won’t actually get much audible interference… perhaps the odd drop out or two, but you may notice that while using your microwave oven (this actually sends out static in the 2.4GHz range), talking on your cordless phone or listening in on your baby monitor etc… Things like your WiFi might slow down.
The Solution
So we want something like that fancy baby monitor that can send a picture to your TV, but not have it cause drop outs on your phone or slow your internet.
Most devices come with software that allow you to connect via an iPhone or Android app, letting you tune in when you’re out. Great for checking up that your kids aren’t running amok when being babysat by the grandparents!
The great thing is, these cameras aren’t any more expensive (sometimes a lot cheaper) than the standard video monitors you’re likely to find in a baby shop.
