CS-Mount Lens Applications & Compatible Devices

Ultra Wide-Area Security Surveillance

The defining characteristic of this lens is its exceptionally broad field of view. With 131° horizontal FOV and 99° vertical FOV, a single camera can capture a very large scene from a fixed installation position.

Designed for ultra wide-angle CCTV surveillance applications where maximizing scene coverage is more important than maintaining low geometric distortion.

Typical environments include large indoor spaces, building entrances, retail areas, public facilities, corridors, lobbies, and other locations where a broad field of view is required.

High-Resolution Wide-Angle Monitoring

Unlike conventional wide-angle CCTV lenses designed around lower-resolution camera systems, this lens supports 12MP imaging on a 1/1.7″ sensor. This makes it suitable for surveillance platforms where both extensive coverage and high-resolution image capture are required.

The combination of 12MP resolution and an extremely wide FOV can be useful when security operators need to capture more of the surrounding environment while retaining detailed image information for analysis.

Large Indoor Space Monitoring

The 131° horizontal FOV is particularly useful for indoor environments where a camera needs to observe a large area from a relatively centralized position. Potential applications include warehouses, retail stores, exhibition spaces, commercial buildings, transportation facilities, and large corridors.

The ultra-wide optical configuration can help reduce blind areas in fixed-camera installations, although final camera quantity and placement should always be determined according to the actual site geometry.

For projects requiring different focal lengths or sensor formats, TOWIN’s CS-Mount Lenses portfolio provides additional interchangeable lens options.

IR-Assisted Day/Night Surveillance

The IR Corrected design makes this lens suitable for security cameras operating under both visible and near-infrared illumination. This is particularly relevant for surveillance systems using IR LEDs for nighttime monitoring.

By optimizing optical performance for IR-assisted operation, the lens can help maintain more consistent focus when illumination conditions change between daytime visible light and nighttime infrared lighting.

Security Cameras Requiring Maximum Scene Coverage

The 3.2mm focal length is well suited to applications where coverage is the primary optical requirement. It can be considered for cameras positioned to monitor entrances, open indoor areas, retail floors, lobbies, halls, and other spaces where a conventional 6mm or longer focal length would provide insufficient coverage.

Because the specified distortion is < -64%, this lens should be selected when broad coverage is the priority rather than rectilinear image geometry. It should not be promoted as a low-distortion lens.

Compatible Devices

This lens can be considered for:

• CS-mount 12MP CCTV cameras
• 1/1.7″ high-resolution security cameras
• Ultra wide-angle surveillance cameras
• IR-assisted night vision cameras
• Large-area indoor monitoring systems
• Retail security camera systems
• Warehouse surveillance cameras
• Building entrance monitoring systems
• Commercial facility security cameras
• Fixed-position high-resolution monitoring equipment

For projects where field of view needs to be matched with sensor size and installation distance, TOWIN’s Lens Selection Guide can help evaluate the required optical configuration.

Frequently Asked Questions

Q: What type of camera is this 3.2mm CS-mount lens designed for?
A: This lens serves CS-mount camera systems equipped with 1/1.7-inch image sensors, ideal for high-resolution CCTV cameras that demand ultra-wide scene coverage.

Q: How wide is the field of view of this lens?
A: The lens provides a 160° diagonal FOV, 131° horizontal FOV, and 99° vertical FOV, making it an ultra wide-angle configuration for fixed surveillance applications.

Q: Is this a 12MP CCTV lens?
A: Yes. The specified resolution is 12MP, making the lens suitable for compatible high-resolution camera systems using 1/1.7″ sensors.

Q: Is the 3.2mm lens a fixed focal length lens?
A: Yes. This lens carries a fixed 3.2 mm focal length and fixed zoom configuration. It delivers consistent framing after installation.

Q: Why is IR correction important for this CCTV lens?
A: IR correction helps reduce wavelength-related focus shifts when the camera changes between visible-light and near-infrared illumination. This is particularly useful for surveillance systems using IR illumination at night.

Q: Is this lens suitable for wide-area surveillance?
A: Yes. Its 131° horizontal and 99° vertical FOV make it particularly suitable for applications requiring exceptionally broad scene coverage from a fixed camera position.

Q: Is this a low-distortion lens?
A: No. The specified distortion is below -64%, so this lens is not intended for low-distortion imaging. Its primary advantage is maximizing field of view rather than preserving rectilinear geometry.

Q: Is this lens a fisheye lens?
A: The 160° diagonal FOV is extremely wide, but the supplied specification does not identify the lens as a fisheye design. It is therefore more appropriate to describe it as an ultra wide-angle lens unless the optical design documentation specifically classifies it as fisheye.
