The extra digital XD02812GMP is a compact CCTV zoom lens with a 2.8–12 mm focal length range designed for 1/2.7" image sensors. It provides HD resolution imaging and a variable field of view from wide-angle to short telephoto, making it adaptable for a range of surveillance setups. The lens is built for fixed-mount installation on compatible security cameras and supports common indoor and outdoor monitoring needs where adjustable framing and detail are required.

Advantages

The lens offers flexible framing thanks to the 2.8–12 mm zoom, allowing easy switching between wide coverage and tighter subject focus without changing the camera position. Its optical design is matched to 1/2.7" sensors to preserve image sharpness and resolution at HD quality. The fixed-mount form factor simplifies installation and alignment in both dome and box camera housings. The lens is suitable for continuous surveillance use and maintains consistent performance across typical lighting conditions encountered in security applications.

How to use

Mount the lens into a compatible CCTV camera housing or directly onto a camera that accepts fixed-mount lenses for 1/2.7" sensors. Adjust the focal length between 2.8 mm and 12 mm to set the desired field of view and framing. Focus the lens according to the camera’s focusing mechanism or manual focus ring until the image appears sharp on the monitor. After initial setup, perform test recordings or live-view checks under typical lighting conditions to confirm coverage and detail levels, and make small adjustments as needed.

Usage recommendations

For optimal results, choose a focal length near 2.8 mm for broad-area coverage and near 12 mm for detailed observation of distant subjects. Maintain correct focus and periodically verify alignment after environmental changes or maintenance. Use appropriate housings and weather seals for outdoor installations to protect the lens from moisture and dust, and ensure adequate scene illumination for best HD image quality.
