Wide Angle Lens – CCL12703324MP

CCL12703324MP 3.3mm M12 wide angle lens for 1/2.7″ 2MP sensors, featuring 136.8° FOV

3.3mm M12 Wide Angle Lens | 1/2.7″ CCTV Lens

This 3.3mm M12 wide angle lens is designed for compact camera modules that require an exceptionally broad viewing area within a short optical package. With a 1/2.7″ image format, 136.8° diagonal FOV, 111° horizontal FOV, and 57° vertical FOV, it provides extensive scene coverage for close-range monitoring and embedded imaging systems. The 17.39mm TTL makes the lens particularly suitable for camera designs where installation depth is limited.

With 2MP resolution, a fixed F2.4 aperture, manual focus, and a fixed focal length, this lens offers a straightforward optical configuration for compact surveillance and embedded camera applications. Its M12X0.5 mount allows integration with compatible camera boards and modules, while the 4G optical construction provides a compact solution for applications where wide-angle coverage and reduced lens length are key design requirements.

Key Product Highlights

• 136.8° Ultra-Wide Diagonal FOV — Captures an exceptionally broad scene, helping reduce blind areas when the camera is installed close to the monitored area.
• 111° Horizontal Coverage — Provides extensive lateral coverage for indoor monitoring, entrances, compact security devices, and embedded cameras.
• 17.39mm Short TTL — The shorter optical length helps address installation-depth limitations in compact camera housings and embedded imaging devices.
• Compact M12X0.5 Mount — Designed for camera modules using the widely adopted M12 interface, simplifying integration into space-constrained equipment.
• 3.3mm Fixed Focal Configuration — Provides predictable wide-angle coverage without the mechanical complexity of a zoom or varifocal system.

M12 Wide Angle Lens Applications

This lens is best suited to compact imaging systems where maximum scene coverage and short installation depth are more important than geometric accuracy. Its combination of 3.3mm focal length, 136.8° diagonal FOV, and 17.39mm TTL makes it particularly useful for close-range monitoring and embedded camera designs.

Core Applications

• Compact Indoor CCTV Cameras — The ultra-wide viewing angle allows a single camera to monitor a large indoor area from a relatively short distance, making it useful for rooms, entrances, corridors, and small commercial spaces.
• Smart Home Security Cameras — The compact M12 design and short TTL help camera manufacturers integrate wide-angle optics into small enclosures where internal installation space is limited.
• Door and Entrance Monitoring — The 111° horizontal FOV can cover a broad entrance area, helping capture people or activity approaching from different directions.
• Embedded Vision Modules — The fixed focal length and 17.39mm TTL are well suited to embedded camera boards where optical simplicity and reduced installation depth are important.
• Indoor IoT Cameras — The wide-angle configuration provides broad scene awareness for connected monitoring devices used in homes, offices, retail environments, and other indoor spaces.
• Small-Form-Factor Monitoring Devices — The M12X0.5 interface enables integration into compact devices that cannot accommodate longer C-Mount or CS-Mount optical assemblies.

Compatible Devices

The lens is designed for 1/2.7″ 2MP camera configurations, with the listed FOV based on the OV2710 reference. It can be integrated into compatible M12 camera boards, compact CCTV modules, embedded vision cameras, smart security devices, and other imaging equipment supporting an M12X0.5 lens interface.

For manufacturers requiring additional M12 optical configurations, TOWIN’s M12 Lenses portfolio provides different focal lengths and optical designs. For broader security-camera requirements, Megapixel CCTV Lenses offer additional options.

The specified TV distortion of <-16% indicates that this model prioritizes very wide-angle scene coverage rather than precision geometric reproduction. Therefore, it is better suited to monitoring and situational-awareness applications than dimensional inspection or applications where straight-line preservation is critical. For those requirements, TOWIN’s Low Distortion Lenses are a more appropriate category to evaluate.

When selecting the lens for a specific camera module, customers should verify the sensor format, active image area, mechanical clearance, focus position, and required field of view. TOWIN’s FOV Calculator can also help evaluate focal length and field-of-view requirements.

Frequently Asked Questions

Q: What sensor size is this 3.3mm M12 lens designed for?
A: This lens is designed for a 1/2.7″ image format, with the listed field-of-view specifications referenced to the OV2710 sensor.

Q: What is the field of view of this M12 wide angle lens?
A: The lens provides a 136.8° diagonal FOV, 111° horizontal FOV, and 57° vertical FOV in the specified OV2710 configuration.

Q: Is this a fixed focal length lens?
A: Yes. The lens has a fixed 3.3mm focal length and does not provide zoom or varifocal adjustment.

Q: What aperture does this lens use?
A: The lens uses a fixed F2.4 aperture and fixed iris configuration.

Q: What is the advantage of the 17.39mm TTL?
A: The 17.39mm TTL provides a relatively short optical package, which can simplify integration into camera housings and embedded devices where available installation depth is limited.

Q: Is this lens suitable for CCTV cameras?
A: Yes. Its ultra-wide FOV, 1/2.7″ image format, 2MP resolution, and compact M12X0.5 interface make it suitable for various compact indoor CCTV and security camera applications.

Q: Is this lens suitable for precision machine vision inspection?
A: It is generally not the preferred choice for precision measurement because its specified TV distortion is below -16%. Applications requiring accurate dimensional measurement or geometric reproduction should consider a dedicated low-distortion machine vision lens.

Q: Can this lens be used with other sensors besides OV2710?
A: The listed FOV values are based on the OV2710 configuration. Evaluate compatibility with another sensor according to its active image area, sensor format, optical position, and mechanical interface.
