General :: Phone To Phone Wireless Camera?

I would like to use an old deactivated phone as a wireless camera, not over WiFi, but something like AdHoc(I think).

Where my deactivated (old) phone can broadcast a wifi network that my other phone will be able to connect and view the cam's video.

Something like: Old Phone(No internet/service) makes a WiFi AP that Another Phone can connect to and view the video the Old Phone is streaming.

I've found tons of IP cams which use an existing wireless network, but I want the old phone to be used as the wireless router.
