2MP 3.6mm CS-Mount Wide Angle IR Corrected CCTV Lens

This 2MP 3.6mm CS-mount wide angle CCTV lens delivers a 91° horizontal field of view, F1.6 aperture, and IR-corrected optical performance for broad-area CCTV surveillance. Its short 3.6mm focal length is designed for security cameras that need to capture a wide scene from a fixed installation position.

Product Core Highlights

• 3.6mm short focal length provides broad scene coverage for fixed-position CCTV.
• 91° horizontal FOV captures a wide monitoring area from a single camera position.
• F1.6 aperture provides a relatively bright optical configuration for indoor surveillance.
• 2MP resolution supports standard high-definition security camera applications.
• IR-corrected optics help maintain focus consistency across visible and near-infrared wavelengths.

Applications & Compatible Devices

Core Application Scenes

This 3.6mm CS-mount wide angle CCTV lens is designed for surveillance locations where the camera needs to capture a large surrounding area rather than concentrate on a distant target. Its 91° horizontal field of view makes it suitable for fixed cameras positioned near the monitored scene.

Typical applications include building entrances, reception areas, corridors, retail stores, small offices, indoor public spaces, and general security monitoring. The short focal length allows a camera to cover a relatively broad area without requiring a motorized zoom mechanism.

The lens is especially useful when the installation position is predetermined and the required viewing angle remains relatively constant. Once manually focused, its fixed 3.6mm configuration provides stable framing for continuous surveillance.

The F1.6 aperture and IR-corrected optical design further support indoor CCTV applications where lighting can change between daytime and nighttime operation or where infrared illumination is used.

For selecting the correct lens according to sensor format, installation distance, and required field of view, engineers can refer to Towin’s Lens Selection Guide.

Compatible Device List

• 1/2.7″ 2MP CCTV cameras: Designed for security camera systems using 1/2.7″ image sensors with 2MP imaging requirements.
• CS-mount security cameras: Compatible with camera bodies using the CS mounting interface.
• Wide-area indoor surveillance cameras: Suitable for offices, retail spaces, reception areas, corridors, and other indoor locations.
• Entrance monitoring cameras: The 91° horizontal FOV provides broad coverage around doors and access points.
• General security monitoring equipment: Suitable for fixed-position cameras where wide scene awareness is required.
• Day/night CCTV cameras: IR correction supports systems using near-infrared illumination for nighttime monitoring.

For integrated security applications, this lens can be evaluated with Towin’s Smart Security solutions.

Optical Selection Considerations

The 3.6mm focal length and 91° horizontal FOV provide significantly broader coverage than longer fixed focal lenses such as 8mm, 12mm, and 16mm configurations. This makes the lens more appropriate for nearby scenes and areas where a camera must capture a larger portion of the environment.

The actual coverage will depend on the 1/2.7″ sensor dimensions and the camera’s mounting distance. Engineers can use Towin’s Focal Length Calculator to estimate the required focal length for a specific scene.

Although the lens provides a 91° horizontal field of view, no distortion specification is supplied. Therefore, it should be classified as a Wide Angle Lens rather than a Fisheye Lens based on the available specifications. Applications requiring controlled geometric distortion should be evaluated using the Distortion Guide.

Frequently Asked Questions

Q: What type of lens is this 3.6mm CS-mount lens?
A: It is a 2MP fixed focal CCTV lens with a 3.6mm focal length, CS mount, F1.6 aperture, manual focus, and IR-corrected optical performance.

Q: What is the horizontal field of view of this lens?
A: The specified horizontal field of view is 91° when used with the stated 1/2.7″ image format.

Q: Is this 3.6mm lens a wide angle lens?
A: Yes. Its 91° horizontal field of view provides broad scene coverage and makes it suitable for wide-angle CCTV surveillance applications.

Q: Is this lens a fisheye lens?
A: It is not classified as a fisheye lens based on the supplied specifications. Although the 91° horizontal FOV is wide, there is no information confirming a fisheye optical design or the characteristic extreme distortion associated with fisheye lenses.

Q: Is the focal length adjustable?
A: No. The lens has a fixed 3.6mm focal length. Focus is manually adjusted during installation.

Q: What camera sensor is this lens designed for?
A: The specified image format is 1/2.7″, and the lens is rated for 2MP imaging applications.

Q: What does IR corrected mean on this lens?
A: IR correction reduces focus shifts between visible and near-infrared wavelengths and helps maintain consistent focus in day/night CCTV systems.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.1m, allowing the lens to focus on relatively close subjects when required by the camera installation.
