CS-Mount Lens Applications & Compatible Devices

Core Application Scenes

The combination of a 5mm focal length, 87° horizontal FOV, 12MP resolution, and 1/1.7″ image format makes this lens suitable for applications that require broad scene coverage without moving to an extremely short focal length.

It is particularly suitable for high-resolution fixed surveillance cameras, where the camera needs to monitor entrances, corridors, indoor areas, commercial spaces, or outdoor zones while retaining sufficient image detail for security analysis.

The 5mm focal length provides a more controlled viewing angle than ultra-wide 2–3mm lenses, making it a practical choice when excessive scene expansion is undesirable. The 12MP optical capability is also well suited to cameras requiring detailed image capture across a relatively wide monitoring area.

Designed for high-resolution wide-area surveillance applications, this lens can be integrated into professional CCTV cameras, IP surveillance systems, security monitoring equipment, and other imaging platforms using a CS-mount interface.

Compatible Devices

This lens can be used with:

• 1/1.7″ high-resolution CCTV cameras
• 12MP IP security cameras
• Fixed surveillance cameras
• Indoor and outdoor monitoring cameras
• Commercial security camera systems
• Building entrance monitoring systems
• Retail and facility surveillance cameras
• Industrial area monitoring cameras
• Day/night security cameras with near-infrared illumination

For systems where lens and sensor matching is critical, TOWIN’s Sensor Guide can help engineers evaluate sensor format compatibility, while the Lens Selection Guide provides additional guidance for choosing focal length, FOV, and lens configuration.

Wide-Area Surveillance with High Image Detail

The 87° horizontal FOV offers broad scene coverage while the 12MP resolution helps preserve image detail. This balance makes the lens useful for monitoring spaces such as building entrances, retail interiors, reception areas, corridors, parking zones, and facility perimeters, where both coverage and image clarity are important.

The -43% distortion specification should not be marketed as a low-distortion feature. Instead, the lens should be positioned around its wide-angle coverage and high-resolution imaging capability. For applications where geometric accuracy is a primary requirement, users can refer to TOWIN’s Distortion Guide when evaluating alternative optical configurations.

Day & Night Surveillance

The IR-corrected design makes this lens particularly relevant to surveillance cameras that operate under both visible-light and near-infrared illumination. IR correction helps maintain a more consistent focal position when lighting conditions change, supporting applications that use IR LEDs for nighttime monitoring.

This makes the lens suitable for 24/7 CCTV systems, security cameras with IR illumination, building surveillance, perimeter monitoring, and other day/night imaging environments.

Why Choose This 5mm CS-Mount Lens?

Frequently Asked Questions

Q: What sensor size is this 5mm CS-mount lens designed for?
A: This lens is designed for 1/1.7″ image sensors and is suitable for high-resolution CCTV cameras using this sensor format.

Q: What is the horizontal field of view of this lens?
A: The lens provides an 87° horizontal FOV, with a 114.4° diagonal FOV and 62° vertical FOV.

Q: Is this a wide-angle CCTV lens?
A: Yes. With an 87° horizontal field of view at a 5mm focal length, it is positioned as a wide-angle CCTV lens for broad-area surveillance.

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

Q: Is this lens suitable for day and night surveillance?
A: Yes. The lens is IR corrected, making it suitable for CCTV systems that switch between visible-light imaging and near-infrared illumination.

Q: What type of mount does this lens use?
A: This lens uses a CS mount, making it suitable for compatible professional CCTV and security camera platforms.

Q: Is this lens a low-distortion lens?
A: No. The specified distortion is -43%, so it should be positioned as a wide-angle lens rather than a low-distortion optical solution.

Q: Can this lens be used for industrial monitoring?
A: Yes. It can be considered for industrial monitoring cameras where wide-area coverage and high-resolution imaging are required, provided the camera system is compatible with the 1/1.7″ format and CS mount.
