Product Description

The lens of a surveillance camera is the camera’s window to the world. This is a piece of glass (or in some cases, a piece of plastic). The lens focuses the light from the outside world onto the image sensor of the CCTV camera.

There are 2 general types of lenses for security cameras. Fixed and Varifocal Lenses. I will expand on this a little later.

The Focal Length of a Surveillance Camera

Security surveillance cctv camera lens MJ3621A

Ok – back to the focal length of a surveillance camera. The focal length is the gap between the image sensor and the lens. A CCTV Camera’s focal length is measured in millimetres (mm). This is the distance between the lens and the image that is required for a particular lens to produce a sharp image.

You will see an image that is out of focus if the distance between the image sensor and the lens is not exactly right.
