Hi all, trying to upgrade a friends security cam system so he can view a camera feed in another building. Building is linked to where the cam feed is via a WIFI bridge, so need to get the feed on to IP somehow. Camera feed is a standard composite analogue one, currently connected to a dumb screen. Feed is from a camera mounted remotely, so changing the camera to an Ethernet one is not an option.

So far all the solutions I've come across have been varying shades of stupidly expensive. Anyone got any thoughts on an inexpensive solution to the problem?

Complicating factor is that the current location of the feed is going to be a major pain to cable to the nearest ethernet port - so a WIFI interface would be ideal. But if there is a reasonable cabled solution out there we'll bit the bullet and figure out how to run the cabling...

My current line of thinking is a Raspberry Pi embedded PC (http://www.raspberrypi.org/) plus a USB video capture thingy. Would take a bit of hacking to make it work I suspect, and the Raspberry Pis as not available as yet... Surely there must be something like this out there already - just need composite video in on one side, and Ethernet out on the other...
