Should you use a 2.8mm or 4mm lens for CCTV? (multiple scenarios tested)

When shopping for a security system, you can often choose between a 2.8mm and 4.0mm lens camera for the same price. So, which camera should you choose? Well, it depends on the scenario. Typically a 2.8mm camera will have a 20% wider field of view, but the 4.0mm camera will have 20% better image quality. Therefore, which camera you choose will depend on your specific scenario. In this video, we showcase multiple scenarios to compare the strengths and weaknesses of both lens options. We also compare both cameras against a varifocal 2.8 - 12mm dome. If you want to view something far in the distance, you should consider a dedicated varifocal lens camera.
