Please see below a description of what sized lenses come with the IP cameras and what to expect from them.

Fixed 2.8mm Lens/Fixed 3.6mm Lens

A fixed lens CCTV camera lens has a set viewing angle. This means the lens cannot be zoomed, focused or adjusted in any way, the camera lens comes fixed and focused ready to install.. Our 2.8mm/3.6mm fixed lens gives you a wide angle of view as demonstrated in the images on the left. This type of camera is well suited to most areas internally or externally, the wide lens can capture incredible detail over multiple areas such as car parks, factories, supermarkets, airports etc.

Varifocal 3.3-12mm Lens

Compared to a fixed lens, on a varifocal lens you have the ability to change the zoom and focus of this lens. This must be done manually at the camera itself, at either side of the lens. We recommend to change the zoom and focus of your camera once the camera is mounted and is connected to a NVR. Our 3.3-12mm varifocal lens can give you a wide angle of view when zoomed out and focused but when zoomed in, the lens will give you a narrow angle of view. The more you zoom in, the better the detail. The more you zoom out, the less the detail but the wider the area covered. For example, you are able to cover a large open area or you are able to zoom this camera in for a narrow detailed image.

Motorised 3.3-12mm Lens

Motorised lenses are available in some models, this means you are able to change the zoom of this camera from your NVR or via the web browser interface and the camera will automatically change the focus. Because it’s motorised it means you don’t have to change it manually at the camera itself, this can save you a lot of time. Our 3.3-12mm motorised lens can give you a wide angle of view when zoomed out and focused but when zoomed in the lens will give you a narrow angle of view. The more you zoom in, the better the detail. The more you zoom out, the less the detail but the wider the area covered. The biggest benefit from the motorised lens is that it will give you the most perfect focus everytime, something that cannot be guaranteed with a manual lens. The camera resolutions are that high, it will be a shame if you had a manual lens slightly out of focus.

Both the motorised and manual varifocal lens both have the same angle of view, please see examples of these on the left hand side of this text. Please click images to view in their true resoultion.
