HD 3 Megapixel CCTV Lens 16mm CS Mount F1.4 Aperture 1/2.5 inch for Surveillance Cameras Quick overview This 3 megapixel CCTV lens delivers resolution imaging for surveillance camera systems that accept CS mount lenses and 1/2.5 inch sensor format. The 16mm focal length and fast F1.4 aperture provide a focused field of view and improved performance in low light conditions, making it suitable for medium to long range monitoring. Key benefits resolution imaging: Optimized for 3 megapixel sensors to capture sharper detail and clearer video. Better low light performance: Large F1.4 aperture allows more light to reach the sensor, reducing noise and improving image quality in dim environments. Precise field of view: 16mm focal length narrows the viewing angle for capturing distant subjects with greater detail. Easy integration: Standard CS mount fits most surveillance cameras designed for 1/2.5 inch sensors, allowing quick installation and reliable alignment. Main specifications and function Image resolution support: 3 megapixel Focal length: 16mm Mount type: CS mount Maximum aperture: F1.4 Sensor format compatibility: 1/2.5 inch Intended use: Surveillance CCTV cameras Compatibility and installation Designed for surveillance cameras that accept CS mount lenses and have a 1/2.5 inch sensor format. Compatible with CCTV systems where a midtelephoto focal length is required to focus on distant targets or narrow scenes. Simple mechanical installation into a CS mount camera; adjust focus and secure in position for results. Performance notes The combination of 16mm focal length and F1.4 aperture balances distance coverage and light gathering to produce clearer images at moderate to long ranges. Optimized for use with 3 megapixel sensors to take advantage of the lens resolution capability. Typical applications Parking lot and perimeter monitoring where targeted long range detail is needed to identify vehicles or incidents. Entrance, gate, or driveway surveillance to capture faces and license plates at a distance. Indoor corridor or aisle monitoring in warehouses and retail settings where a narrow field of view and good low light sensitivity improve identification. What this lens solves Improves image clarity for mid to long range surveillance tasks. Enhances performance in low light scenarios where smaller aperture lenses would struggle. Provides a straightforward upgrade path for systems that require higher detail on 1/2.5 inch sensors. Technical compatibility checklist Confirm camera accepts CS mount lenses. Confirm camera uses a 1/2.5 inch sensor format. Ensure 16mm focal length meets your field of view and distance requirements. This lens is a practical choice when improved resolution, better low light capability, and a narrower field of view are required for surveillance applications.
