Implant the camera and have it take a feed direct off the optic nerve. Implant the wireless in the head too with some local storage to cover when there is no signal. Active monitoring so if the signal drops for any length of time agents are dispatched to the last known location.
Wouldn't work for me. First time it breaks or is damaged, I get charged 50% of the "Unsubsidised" cost of the phone when issued (£250), then the subsequent times I get charged 100% (£500). The phones are replaced about every 3 -4 years, so in theory I could be charged from £250 to £500 for having a 4 year old phone break on me. This comes straight from my wages as a deduction on my payslip.
