It's nothing new, but thought I'd try it - £2.99 on the App store. Watch all your home web cams from your iPhone. Works on pc or mac. Probably android too.
Just got a puppy so it'll be useful when I'm out to make sure he's not eating the furniture. Handy for catching burglars too - or at least watching them walk off with your laptop. It's got a motion sensor you can set to trigger recordings. Got it rigged up to two cams - dead easy to set up. All kinds of espionage activity may ensue.
