Covert/Undercover Surveillance Equipment

[cmorning]

I am trying to find a decent covert/undercover system (audio and video) for our narcotics unit. So far I've found the Oculus system and a system from Adaptive Digital Systems. I need to find one more for quote purposes. The units I'm looking at cost around $10,000 or so. Any ideas of another system would be greatly appreciated....Thanks, CLM
