How do I choose the right lens for my security camera?
Detailed to a greater extent in the A1 Security Cameras Blog (How to Choose the Best Lens for Your Security Camera), choosing the right lens for your security camera is specific to the area being monitored. For small spaces that require a narrow view or focus, 6mm to 12mm lenses are perfect. For hallways, rooms inside of a home, or offices, the 2.8mm lens is perfect.

Typically, security cameras use one of three types of concave lenses, a monofocal lens, varifocal lens, and zoom lens. These lenses come in various sizes with examples like:

What is the difference between a 2.8mm and 4mm lens?
The differences between 2.8mm to 4mm are not significant, but there are differences in these and lenses similarly different in size. The smaller of the two provides a detailed depiction of objects within view and features a slightly wider view at that. However, the 4mm lens produces clearer footage at a slightly farther distance.
