If you want exact data, you might need special testers. Actually, the most important spec of the camera is its resolution. The chips determine the resolution. When you buy a camera, you should choose the proper CCD and its project. It is not hard to identiy the CCD model.

Some of our customers also have this kind of demands. Frankly, I also want to make this kind of course for my customers.

What I had seen the oldest cameras came from an old fatory. Frankly, I didn't know its real function. I asked the guy. He said that it used for checking radiative things. Horrible

Anyone who can suggest some useful Expo in US?

faint, the poor guy.

LOL. Funny.

LOL. Kind of dirty...

There are many choices. It is based on the environment and the needs. You should describe detailedly about the shop. Normally, the shop would use dome cameras and box cameras. For example, if the shop sells diamands, you'd better choose famous brand with high definition, WDR , low illumination function, etc.

Kenny, For the current conditions, you'd better choose a camera with Sony CCD. It's better choice. Based on your budget, if it's enough, you could choose some cameras manufacured by Sony, Panansonic, Samsung, etc. If your want to save money, you could buy some cameras manfactued by China facotory. Indeed, most of the cameras are manufacured in China, even Sony, Samsung and other famous brands. Obviously, no company would manufacture cameras in USA. It costs too much. Andy
