What is the camera's shooting range? How much is the diameter?
Can you say what the next camera, mobile phone, computer, monitor, or what?
The lens used in the camera is similar to the SLR camera, and is arranged in the order of 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm, 24mm and so on. The smaller the number of millimeters, the wider the picture taken by the lens, but the closer the distance is; the larger the number of millimeters, the narrower the screen taken by the surveillance camera, but the farther the distance is.
