ITS Lens – C252312M5

C252312M5 is 5MP 25mm F1.2 low distortion ITS lens,In “F1.2 ITS Lens“, ITS usually refers to lenses related to the Intelligent Transportation System.

25mm F1.2 C-Mount 5MP ITS Lens for Traffic Monitoring

This 25mm F1.2 ITS lens is a high-aperture C-Mount lens designed for intelligent transportation systems, traffic monitoring, license plate recognition, and long-distance road imaging. With a 2/3″ image format, 5MP resolution, 25.5° diagonal FOV, and manual iris, focus, and zoom adjustment, it provides flexible optical control for demanding traffic surveillance environments.

The F1.2 aperture is particularly valuable for low-light traffic monitoring, helping maintain image brightness when illumination changes from daytime to nighttime. Its 25mm focal length provides a relatively narrow field of view for focused road scenes, vehicle identification, and traffic analysis.

Product Core Highlights

• F1.2 large aperture provides strong light-gathering capability for traffic monitoring in low-light and nighttime conditions.
• 5MP high-resolution imaging supports vehicle, license plate, and road-scene recognition applications.
• 25mm focal length with 25.5° diagonal FOV provides focused coverage for targeted traffic monitoring zones.
• Manual iris, focus, and zoom adjustment allows installers to optimize image performance for different lighting and monitoring distances.
• C-Mount compatibility makes the lens suitable for a broad range of professional traffic cameras and industrial imaging systems.

F1.2 ITS Lens Applications

Core Application Scenes

This F1.2 ITS lens is designed for intelligent transportation and traffic surveillance systems that require high image brightness, controlled field coverage, and flexible optical adjustment.

Its 25mm focal length is suitable for monitoring defined areas of a roadway rather than extremely wide scenes. The F1.2 aperture is especially useful where traffic cameras must capture vehicles under changing illumination, including dusk, nighttime, and poorly lit road environments.

Typical applications include:

• Intelligent transportation systems (ITS)
• Traffic monitoring
• License plate recognition (LPR/ANPR)
• Vehicle identification
• Roadside surveillance
• Intersection monitoring
• Toll station monitoring
• Highway surveillance
• Traffic violation detection
• Vehicle counting and classification
• Road safety monitoring
• Urban traffic management

Designed for intelligent transportation and low-light traffic monitoring applications.

The combination of focal length, sensor size, and FOV is important when selecting an ITS lens. Our Lens Selection Guide can help engineers evaluate the appropriate optical configuration.

Compatible Device List

This 25mm C-Mount ITS lens can be integrated with:

• Traffic monitoring cameras
• ANPR/LPR cameras
• Highway surveillance cameras
• Intelligent traffic cameras
• Roadside monitoring systems
• Toll station cameras
• Intersection monitoring cameras
• Vehicle recognition systems

For traffic applications requiring detailed vehicle or license plate imaging, the camera sensor and lens should be selected together. The Sensor Guide provides additional information about sensor format and lens compatibility.

Optical Design Considerations

The 2/3″ image format and 25mm focal length provide a relatively focused field of view of 25.5° diagonal, 20° horizontal, and 15° vertical. This makes the lens appropriate for applications where the monitoring area is clearly defined.

The F1.2 aperture is one of the key advantages of this lens. A larger aperture allows more light to reach the sensor, which can be beneficial when capturing moving vehicles under low illumination.

The manual iris allows the optical system to be adjusted according to the lighting environment, while manual focus and zoom provide installation flexibility for different monitoring configurations.

For applications where image geometry affects recognition or analysis, distortion should also be considered. Learn more through our Lens Distortion Guide.

Frequently Asked Questions
