General Forum - Wireless webcam/spycam for prank? - Page 1

This is something I've never looked into before so so advice would be much appreciated from you good folk Setting up a prank on a mate and we want to film it as it won't be something we'll be able to watch so wondering on tips for what would be best to do.

Basically it will be in the corridor of his flats, where another mate also lives, so we can use his wireless router if that helps. Need to setup some sort of camera in the corridor to record it (so the camera would need to be battery powered). Would need to be small too so that it won't be noticed (thinking of attaching it to the ceiling)

Obviously just looking for something cheap as it won't be reused really, can anyone point me in the right direction please?
