The Null Device
First there were cinema verité, DOGME 95 and machinima, and now we have "Video Sniffin'". This latest technique in improvised guerilla filmmaking involves finding a (presumably unsecured) wireless CCTV camera and acting out a scene from your underground film in front of it, whilst recording its signal using a receiver:
Young people from the local YMCA and others used a cheap video receiver from a high street store to ‘sniff’ the streets for CCTV cameras. After finding 24 cameras or ‘hotspots’ they then asked shop owners if they could make a film by acting out in front of their CCTV cameras and recording the signal. The shop owners were very surprised and happy for the young people to create a film this way.
