Theia SL940P 4K compatible varifocal telephoto lens can be used for remote surveillance and license plate recognition.
It is designed for sensors such as 1/2.5" 5MP and 1/2.3" 4K resolution.
Excellent IR correction allows day/night operation without the need to refocus when switching to IR illumination.
The lens can be adjusted for focal lengths from 9-40mm, ensuring the right image details.

Similar to Theia's other lenses, the SL940P is a high-quality lens that allows installers to take full advantage of the high resolution of HD and multi-megapixel cameras. The lens can be used on cameras with resolutions up to five megapixels and provides a sharp image from edge to edge.
The lens is IR corrected for use with true day/night cameras. This IR correction focuses IR light from artificial lighting to the same plane as visible light, so the image remains sharp when the day/night camera switches to night mode, unlike lenses without IR that require refocusing.
