What's the difference?

What's the difference between 2.8mm & 3.6mm we hear you ask?

We understand that CCTV systems may seem complex, and it's impossible to tell what the difference between one camera and another is, so we want to make it really easy for you.

A security camera lens size determines the field of surveillance view and zoom level that the camera provides. A 3.6mm lens is designed to provide an approximate 78° field of view and is the perfect camera in most CCTV applications.

Most people think that a 3.6mm lens won't show a large field of view, but as you can see from the below images, there's not a huge difference between a 2.8mm and 3.6mm lens.

As you can see in the images below, you still get an extremely detailed field of vision and depending on your installation and what you want as an end result, you will find that a 3.6mm lens is actually more beneficial than a 2.8mm lens.

We've also created a handy comparison document that you can download.

The images shown are taken from our UNV 4MP Fixed Lens Turret Cameras.
