We use a Tomy one:
Works pretty well. Video with infrared, temperature sensor, night-light with rotating colours, and two-way sound (so you can tell baby to shut up without having to get up from the X-factor).
We still have it in our 3 year olds room, so we can make sure she is sleeping instead of getting up to play as soon as we go downstairs.
And we've bought a second camera for our latest arrival. (Both cameras can talk to one screen).
Only really suffers from interference when the microwave is on or if the phone is next to it and downloading something.
Pricey new, but usually a few bargains on eBay.
I was skeptical about a video monitor first time around as the missus was already quite fretful and had us literally tiptoeing round the house - but actually it really helped her relax because she could see that baby wasn't really waking up every time one of us farted.
is the baby not sleeping in your room for a few months?
Fair point. No rush. You'll probably have the baby in your room for the first six months or so anyway, especially if your missus is breastfeeding.
They come with a built in alarm that is loud enough.
Loud enough to hear a baby choking on its own vomit when you are downstairs with the telly on?
Remarkably good hearing you have.
