AtHome Video Streamer instantly turns your Mac computer into a video surveillance camera. Pairing with AtHome Camera App, you can access and control the home security camera from anywhere at anytime.
Features
Remote monitoring on the go: Watch live video via 3G/4G or WiFi anytime anywhere using your iPhone/iPod/iPad.
Motion detection: Whenever motion is triggered, the 30-second video will be recorded, with email and push notification to inform you of the event.
Like most free apps there is no manual or even hints on how to use it.
They even left off the link to the developer.
At least to me it's not very intuitive either.
