Fixed 2.5 mm F1.8 lens for 1/3 sensors

The Bluecctv LB-CLB0205 is a wide-angle surveillance accessory with a fixed 2.5 mm focal length and an F1.8 aperture. It is designed for cameras using a 1/3 inch image sensor. This lens suits installers who need a broad field of view in a compact form factor.

Practical limits of the fixed wide-angle design

The 130° angle of view captures a wide scene but cannot be adjusted for narrower coverage. The fixed focal length prevents optical zoom or framing changes after installation. The F1.8 aperture supports low-light imaging yet depth of field remains shallow at close distances. Buyers who need variable focal lengths or remote zoom control should select a varifocal lens instead.

Questions about this item

Should I choose the 2.5mm focal length or a longer one for my camera?

The 2.5mm focal length gives a 130° angle of view, ideal for wide-area coverage on a 1/3 image sensor.

What does the F1.8 aperture mean for night-time recording?

The F1.8 aperture gathers more light, helping the sensor produce brighter, clearer footage in low-light conditions.
