We call ours eyeCamD; you can call yours BETTER and CHEAPER! Stop paying $400, $500 or more for document cameras right now. Using a few supplies from your local hardware store, you can use a high quality webcam as a document camera with TONS more functionality.
-Logitech 9000 webcam (8 mega pixels, the Avervision CP150 is 3.2 mega pixels)
-PVC pipe (we used 1/2")
-3 layers of 1/2" MDF (Medium Density Fiberboard-kind of like particleboard but heavier) glued together to form a heavy base
-You can use velcro to affix the camera to the camera arm if needed or you can cut a slot for the bottom "leg" of the camera to go through.
-If you're into appearances, you can use black plastic paint to paint the PVC parts.
-If you're going to paint the base, coat it with a glue/water mixture first to seal the MDF or else you will use a whole can of paint on one base. No kidding. We did it.
In our district, shop students are making bases for our campuses. It's a great lesson for them and we're getting a really superior document camera as well as saving $16,500 for EACH of three new campuses that would have had Avervision document cameras!
