Among the myriad of options available, the 1/2.8″ 2.8mm Wide Angle CCTV Lens (Model: S02812812018) stands out as a remarkable choice, offering a blend of superior optical performance and versatile features.

Key Specifications

Image Format and Sensor Compatibility

The S02812812018 lens is designed specifically for 1/2.8″ image format sensors, ensuring seamless integration with a range of high-definition CCTV cameras. It is particularly compatible with popular sensor models such as IMX322, IMX290, and IMX291, all of which are renowned for their 3-megapixel resolution capabilities. This compatibility ensures that users can leverage the full potential of their CCTV systems, capturing detailed and clear images even in challenging lighting conditions.

Optical Performance

• Focal Length: With a 2.8mm focal length, this lens offers a super wide-angle view, making it ideal for monitoring large areas with a single camera. The wide field of view (FOV) reduces the number of cameras needed for comprehensive coverage, thereby lowering installation and maintenance costs.
• Field of View (FOV): The lens provides an impressive Horizontal Field of View (HFOV) of 120 degrees, with variations depending on the sensor used (e.g., 135° for IMX291). This expansive view ensures that no detail escapes the camera’s gaze, enhancing security and surveillance effectiveness.
• Resolution: Supporting 3-megapixel resolution, the S02812812018 lens delivers crisp and clear images, allowing for easy identification of individuals and objects within the monitored area.
• TV Distortion: Despite its wide-angle capabilities, the lens maintains TV distortion below 26%, ensuring that images remain true to life without significant warping or distortion.
