CS-Mount Lens – CS0812712F3

CS0812712F3 is IR corrected 1/2.7″ CS-mount low-light sensitive lens with 50° diagonal FOV, F1.2 aperture, and 0.3m M.O.D for security surveillance.

1/2.7″ 8mm F1.2 CS-Mount IR Corrected Lens

This 8mm CS-mount IR corrected lens is designed for 1/2.7″ sensors, delivering 3MP resolution, F1.2 aperture, and a 50° diagonal field of view. Its fixed focal design and IR correction support stable imaging for security cameras and day-and-night surveillance systems.

Product Core Highlights

• 8mm Fixed Focal Length — Provides a balanced field of view for medium-distance surveillance and monitoring applications.
• F1.2 Large Aperture — Allows more light to reach the sensor, supporting image capture in challenging low-light conditions.
• IR Corrected Optical Design — Helps maintain focus consistency when cameras switch between visible and infrared illumination.
• 3MP Resolution Support — Suitable for 3MP security cameras and surveillance imaging systems using 1/2.7″ sensors.
• CS-Mount Compatibility — Integrates directly with a wide range of CS-mount CCTV and security camera platforms.

8mm CS-Mount IR Corrected Lens Applications

Core Application Scenes

This CS-mount IR corrected lens is designed for surveillance systems that require reliable imaging under changing illumination conditions. The 8mm focal length provides a narrower field of view than typical wide-angle security lenses, making it suitable for monitoring entrances, corridors, access points, parking areas, perimeter zones, and other medium-distance scenes.

The F1.2 aperture is particularly useful for security cameras operating under limited ambient light. Combined with IR correction, the lens can maintain more consistent optical performance when a camera changes between daytime visible-light imaging and nighttime infrared illumination.

The manual focus structure and fixed iris make the lens suitable for applications where the camera is installed and calibrated during deployment rather than continuously adjusted during operation.

Designed for professional security surveillance and day-and-night monitoring applications.

Frequently Asked Questions

Q: What sensor size is this 8mm lens designed for?
A: This lens is designed for 1/2.7″ image sensors and supports up to 3MP resolution.

Q: Is this lens a fixed focal lens or zoom lens?
A: It is a fixed focal lens with an 8mm focal length. The “Zoom” specification is fixed, so the focal length cannot be continuously adjusted.

Q: What is the field of view of the 8mm lens?
A: The lens provides a 50° diagonal, 40° horizontal, and 30° vertical field of view on the specified 1/2.7″ sensor.

Q: What is the advantage of the F1.2 aperture?
A: F1.2 provides a relatively large aperture, allowing more light to reach the image sensor and supporting surveillance imaging in low-light environments.

Q: Why is IR correction important for a security camera?
A: IR correction helps the lens maintain more consistent focus when the camera operates under visible light and infrared illumination, which is important for day-and-night surveillance.

Q: Does this lens use a CS mount?
A: Yes. The lens uses a standard CS mount and is intended for compatible CS-mount camera platforms.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.3m, allowing the lens to focus on subjects from approximately 0.3 meters away under the specified optical configuration.

Q: Can this lens be used for CCTV surveillance?
A: Yes. Its 8mm fixed focal length, F1.2 aperture, 3MP resolution support, CS mount, and IR corrected design make it suitable for CCTV and day/night security camera applications.
