CS-Mount Lens – CCL117080MPCS

CCL117080MPCS CCTV lens 1/1.7″ 8mm IR corrected CS-mount lens 12MP IMX226 F1.8 day night security fixed Iris

8mm CS-Mount 12MP Wide Angle IR Corrected CCTV Lens

The 8mm CS-mount CCTV lens is designed for 1/1.7″ sensors and delivers 12MP high-resolution imaging with a 56° horizontal field of view. Featuring an F1.8 fixed aperture, IR-corrected optical design, and 8mm BFL, this lens provides controlled wide-angle coverage for professional surveillance and monitoring systems that require both scene coverage and image detail.

Product Core Highlights

• 12MP High Resolution – Supports detailed image capture for high-resolution surveillance cameras.
• 8mm Controlled Wide-Angle Coverage – Provides 56° horizontal FOV for monitoring a defined area without the extreme perspective of ultra-wide lenses.
• F1.8 Aperture – Provides a relatively bright optical configuration for surveillance applications operating under changing lighting conditions.
• IR Corrected Design – Helps maintain focus consistency across visible and near-infrared wavelengths for day/night CCTV systems.
• 1/1.7″ Sensor Support – Designed for high-resolution camera platforms using 1/1.7″ image sensors.

CS-Mount Lens Applications & Compatible Devices

Core Application Scenes

The 8mm focal length and 56° horizontal FOV give this lens a more controlled viewing angle than shorter wide-angle CCTV lenses. This makes it suitable for applications where the camera needs to cover a defined area while maintaining useful image detail toward the center and edges of the scene.

With 12MP resolution, the lens is well suited to high-resolution surveillance cameras used for monitoring building entrances, corridors, retail spaces, office areas, parking facilities, industrial sites, and controlled outdoor zones.

Unlike an ultra-wide lens intended to capture an entire scene from a very short distance, this 8mm configuration is better positioned for targeted area surveillance, where excessive scene distortion or overly broad coverage is not the primary objective.

Designed for high-resolution targeted surveillance applications, the lens can be integrated into professional CCTV cameras, IP security cameras, commercial monitoring systems, and fixed-position security platforms equipped with a CS-mount interface.

Targeted Security Monitoring

The 56° horizontal FOV provides a useful balance between coverage and scene control. It can be used when a security camera needs to monitor a specific entrance, passageway, retail aisle, production area, or outdoor zone rather than an extremely large panoramic area.

The 8mm focal length can also help system designers create more application-specific camera coverage by positioning the camera at an appropriate working distance from the target area.

For engineers selecting focal length based on sensor size and required coverage, TOWIN’s Lens Selection Guide provides additional guidance on matching lens characteristics with imaging requirements.

High-Resolution CCTV Imaging

The combination of 1/1.7″ sensor format and 12MP resolution makes this lens suitable for modern high-resolution security cameras where image detail is important.

Potential applications include:

• Building entrance monitoring
• Retail and commercial surveillance
• Office and facility security
• Parking area monitoring
• Industrial facility surveillance
• Warehouse monitoring
• Access-point monitoring
• Outdoor fixed-position CCTV

The lens is particularly useful where the camera must capture a defined monitoring area while retaining enough resolution for detailed image analysis.

Day & Night Surveillance

The IR-corrected optical design makes this lens suitable for surveillance cameras that operate under both visible light and near-infrared illumination. IR correction helps reduce focus shifts when a camera changes between daytime imaging and nighttime operation with IR LEDs.

This makes the lens appropriate for 24/7 security cameras, day/night IP cameras, perimeter monitoring systems, building security cameras, and other CCTV platforms using near-infrared illumination.

For systems requiring broader coverage, TOWIN also offers Wide Angle Lenses, while the Distortion Guide can help engineers evaluate the trade-off between field of view and geometric distortion.

Compatible Devices

This 8mm lens can be integrated with:

• 1/1.7″ 12MP CCTV cameras
• High-resolution IP security cameras
• Fixed surveillance cameras
• Day/night security cameras
• Commercial monitoring cameras
• Building security systems
• Retail surveillance systems
• Parking and facility monitoring cameras
• Industrial monitoring cameras

Why Choose This 8mm CS-Mount Lens?

Frequently Asked Questions

Q: What sensor size is this 8mm CS-mount lens designed for?
A: This lens is designed for 1/1.7″ image sensors and is suitable for compatible high-resolution CCTV and IP camera systems.

Q: What is the field of view of the 8mm lens?
A: It provides a 70° diagonal FOV, 56° horizontal FOV, and 40° vertical FOV.

Q: Is this an ultra-wide-angle CCTV lens?
A: No. The 8mm focal length provides controlled wide-angle coverage rather than the extremely broad perspective associated with ultra-wide lenses.

Q: Does this lens support 12MP cameras?
A: Yes. The lens is specified for 12MP resolution and is designed for high-resolution imaging systems using a compatible 1/1.7″ sensor.

Q: Is the 8mm lens suitable for day and night surveillance?
A: Yes. Its IR-corrected optical design makes it suitable for CCTV cameras that use near-infrared illumination during nighttime operation.

Q: What type of camera mount does this lens use?
A: It uses a CS mount and can be installed on compatible professional CCTV and security camera platforms.

Q: Is this a low-distortion lens?
A: No. With a specified distortion of -16%, it should be positioned as a controlled wide-angle CCTV lens rather than a low-distortion lens.

Q: What applications are suitable for this 8mm CCTV lens?
A: It is suitable for targeted surveillance applications such as building entrances, retail areas, parking facilities, offices, warehouses, industrial sites, and other fixed monitoring zones.
