Suspicionless surveillance does not become okay simply because it's only victimizing 95% of the world instead of 100%.

How to fool a criminal?  First, order a fake CCTV camera.  It looks pretty authentic and, once the batteries are installed, flashes red on and off once a second.  Semi-convincing but proper CCTV can be made to react to movement, so regular flashes are not as realistic.

Maybe design a better circuit which flashes two LEDs randomly to simulate both target acquisition (red) and data transmission or recording (green).

To make the battery requirements minimal, program a small micro-controller to flash the lights. Include in the code the ability to "sleep" when required to further minimise energy requirements.

Wired and ready to go

A little bit of soldering...

Damn small those soldering points!

 ...and then sneak the whole thing into the barrel of the fake camera.

Which begs the obvious question - where are the real cameras? ;)

P.S. Computer music for the CCTV video footage provided for by...a computer!
