Choosing a suitable lens for your security camera, you need first to determine how far you want to monitor the scene. A 4mm lens will give a 72 degree visual angle of view for a person's face detail in about 30 feet. This will be adequate for most home or small office surveillance system. Based on this calculation, a 8mm lens will give a 40 degree visual angle and zoom in 2 times of the view in the same distance.

The higher the number of the focal length, the more telephoto the effect. *However- this has nothing to do with the actual size of the lens itself. You can obtain a 3.6mm lens which can range in physical size from 1mm (on a micro pinhole type camera) to the size of a soda can (for much larger security type cameras).

A typical highway lane is about 3m wide. To see the full width of a four lane highway you will want a viewing width of about 50 feet. For the distance behind you, you will want to see at least 10 car lenghts in order to make safe lane changes. If we use a car lenght of 3m for the calculation, you will want to see an area of 15m wide at 30m back. All camera angles will suffice for back-up or rear-view systems.

While a larger number of lens on a camera gives a lenticular print a wider angle of view of the 3D effect, as in all facets of photography, the quality of a 3D photograph is more determined by the skill of the photographer than the equipment used.
