Excuse the crummy pics. Introducing the OkeyCam 7000
This is a home made wireless target cam for long range shooting. It runs off a motorcycle or car battery. It uses a plain old camcorder camera, and a 2.4 Ghz wireless digital link. The goal was to design something that has at least a 1000 yard range with good battery life. The transmitter puts out less than a watt, and runs on 12 volts. The camera runs on 7 volts, so there's an on-board voltage regulator. The system draws a little less than an amp, so battery life estimate is simply the amp hour rating of the battery. Everything was done to permit fairly rough handling, but it's obviously not bullet proof. It will last until somebody puts a 6mm hole in it .
Back at the shack, there's a high gain receive antenna, the receiver, and a wall mounted flat TV. Since the transmitter is fairly low power, we needed lots of antenna gain. I think the guys are going to test it today. we cobbled the system together and tested it at 100 yards before the conversion to DC power. It had lots of headroom, and should perform well without adding any more antenna gain. Last time I was out there, the antenna wasn't dead on the berms. I wanted to go out for the tests, but am in ammo hell right now.
Anyway... that's my story. We'll see how it works.
