CCTV Fixed Lens 3MP 2.5mm CSMount NonZoom Lens for CCTV and DSLR Short description A compact 2.5mm fixed focal length lens designed for HD video and imaging systems. Supports up to 3MP resolution and fits cameras with a CS mount. Nonzoom construction provides a stable, consistent field of view for surveillance and wideangle imaging applications. Key benefits Clear HD imaging: Designed for use with 3MP sensors to deliver sharp, resolution images for monitoring and recording. Simple installation: CSmount interface makes the lens compatible with a wide range of CCTV cameras and camera bodies that accept CS mounts or adapters. Consistent framing: Fixed, nonzoom focal length removes zoom variability and helps maintain a predictable coverage area once installed. Wide coverage: The short 2.5mm focal length provides broad scene coverage, reducing the number of cameras needed to monitor larger areas. Low maintenance: Fewer moving parts than zoom lenses, which simplifies setup and reduces potential points of failure. Specifications and compatibility Focal length: 2.5mm fixed (nonzoom) Resolution support: Up to 3MP HD Mount type: CS mount Intended use: CCTV and DSLR imaging systems compatible with CSmount lenses Practical applications Retail and entrance monitoring: Capture wide entrances and checkout areas with a single lens to monitor customer flow and activity. Indoor room and corridor surveillance: Provide consistent, wide coverage in offices, hallways, and public spaces where a fixed field of view is preferred. Wideangle imaging for documentation: Use with compatible DSLR setups for broad scene shoots such as interior spaces or archival imaging where a fixed wide focal length is required. Installation and use tips Confirm your camera accepts CSmount lenses or use the appropriate adapter before installing. Because this is a fixed, nonzoom lens, set camera position and orientation to achieve the desired coverage before final mounting. Verify sensor compatibility with 3MP resolution to ensure full image detail. This lens is intended for users who need a straightforward, reliable fixed focal length solution for HD surveillance and wideangle imaging tasks.
