How to select lens for CCTV Camera ?
The first specification to consider when choosing a security camera lens is its focal length. The focal length of a lens determines both the range and distance of its field of vision. The basic rule to remember is that a smaller focal length will lead to a wider viewable range. Conversely, a larger focal length will have a more narrow field of vision, but it will also have a farther range. A 2.8mm lens has a horizontal viewing Angle of about 110°. A 3.6mm lens with a 90° horizontal viewing Angle, 4mm with a 75°horizontal viewing angle, 6mm with a 60°horizontal viewing angle, 12mm with a 25°horizontal viewing angle.
