This 5MP industrial zoom surveillance camera lens is built for longrange security and inspection tasks that require clear detail at distance. It fits standard CSmount CCTV cameras and offers a manual aperture for precise exposure control. The 550mm focal length provides strong telephoto reach for applications where identifying distant objects is . Key benefits Longrange observation: 550mm focal length delivers magnification for perimeter monitoring, traffic observation, and facility surveillance. resolution support: Optimized for 5 megapixel cameras to preserve image detail at extended distances. Precise exposure control: Manual aperture lets you set the iris for the balance of depth of field and light when automatic control is not available. Easy integration: Standard CS mount ensures compatibility with many CCTV and industrial camera bodies that accept CSmount lenses. Industrial use readiness: Designed for performance in surveillance and inspection contexts that demand reliable optical reach. Important attributes Function: Telephoto surveillance lens for longdistance imaging and monitoring. Resolution support: Suitable for 5MP camera sensors. Mount type: CS mount for straightforward mechanical and optical compatibility with CSmount camera systems. Aperture: Manual aperture control for deliberate exposure and depth of field adjustments. Focal length: FL 550mm, providing narrow field of view and strong magnification for distant targets. Use scenarios Perimeter security: Monitor fence lines, entry points, and large outdoor sites where subjects are often far from the camera. Traffic and parking enforcement: Read signs or capture vehicle details at a distance on highways, bridges, or large lots. Industrial inspection: Observe distant equipment, stacks, or infrastructure components where close access is limited. Installation and compatibility notes Mount to any camera accepting CSmount lenses. Confirm sensor resolution and physical clearances before installation. Use a stable mount or tripod due to magnification; vibrations will affect image sharpness at 550mm. Manual aperture requires user adjustment when lighting conditions change or when depth of field needs to be controlled. This lens provides a focused, practical optical solution when long focal length and 5MP imaging are required for surveillance or inspection tasks.
