Theia Techologies Llc SL940A 9-40mm 5MP Telephoto Lens

Product Description

The THEIA TECHOLOGIES LLC SL940A is a 9-40mm varifocal telephoto lens engineered for 5-megapixel imaging systems operating in both day and night conditions. Covering a focal length range of 9 to 40mm, it delivers the optical reach required for long-distance surveillance and monitoring applications. The day/night design accommodates both visible light and near-infrared illumination, making it suitable for cameras deployed in variable or low-light environments. Installation is performed by security integrators and camera system technicians. The SL940A is a single-unit lens shipped in an each (EA) quantity.

The SL940A is intended for use in IP camera and megapixel camera installations where variable zoom and telephoto reach are required. Typical applications include perimeter security, parking lot monitoring, building access points, and wide-area surveillance where targets may be at extended distances. The 9-40mm zoom range provides flexibility for adjusting field of view during commissioning without swapping lenses. It is suited to both indoor and outdoor installations when paired with a weather-protected camera housing.
