I've worked with digital video cameras for years, though it's been a little while since I've had to buy a mount. In my line of work we often build our own.
The Panavise deluxe mounts in Stevekur1's link are flexible and useful. I've used them quite a bit in the lab. You can set them up quickly and they're reasonably stable. Manufacturers and resellers of good mount equipment include Panavise, Pelco, Newport, Edmund Optics, and others.
Most camera mounts use a 1/4-20 thread. With a little effort you could fashion your own mount out of wood or MDF, a 1/4-20 bolt, some washers, and whatever you want to affix the thing to a wall.
A flexible but pricey solution could be to buy a good-quality tripod with a separable head. You could then fashion mounts on the wall to accept the head. The head would allow you to tweak out the angle and position of the camera. The presence of multiple mounts would allow you to move the camera to different positions (overhead, looking at the front of the rack from behind the head string, etc.). You could use the tripod close to the table for certain shots. This would be a much more expensive option than using a cheap Panavise mount.
A few considerations:
1. Does your camcorder's camera mount have a plastic thread or a metal thread? Choose the 1/4-20 bolt accordingly.
2. Plan for accessibility. If the back end of the camera is too close to the wall it'll be a pain to connect/disconnect it from the mount, to attached cables for a monitor, etc.
3. You may appreciate having extra lights when you're shooting video.
Good luck.[/QUO
