Product Advantages
70mm Long Focal Length
The 70mm focal length provides a narrow viewing angle, making the lens suitable for applications that need to focus on distant or relatively small targets rather than capture a wide scene.
Narrow 4° Horizontal Field of View
With a 4° horizontal FOV, the lens provides concentrated scene coverage and can help isolate specific areas or targets in long-distance monitoring applications.
2MP Imaging for 1/3″ Sensors
The lens is designed for 1/3″ image sensors and supports 2MP resolution, providing a suitable optical configuration for monitoring systems using this sensor format.
Compact M12×0.5 Mount
The M12×0.5 mount allows integration into compact camera systems while maintaining a long 70mm focal length. This makes the lens useful for applications where a small camera interface and narrow field of view are required.
0.5m Minimum Object Distance
The 0.5m minimum object distance provides flexibility for installations where the target may be relatively close while still requiring the narrow-angle characteristics of a long focal length lens.
Manual Focus
The manual focus configuration allows installers or system integrators to adjust the optical focus according to the actual target distance and camera installation conditions.
Applications
Long-Range Monitoring
The 70mm focal length and 4° horizontal FOV make this lens suitable for long-range observation where the camera needs to concentrate on a specific area or target rather than provide broad scene coverage.
Security and Surveillance Cameras
The narrow field of view can be useful for security systems requiring focused monitoring of entrances, restricted areas, corridors, facilities or other defined targets. For broader security imaging requirements, explore TOWIN’s Smart Security Lens Solutions.
Traffic and Road Monitoring
A long focal length lens can be used for selected traffic monitoring configurations where the camera is positioned away from the observation area and requires a narrow viewing angle. For dedicated ITS applications, see TOWIN’s Smart Traffic Lens Solutions.
Industrial Monitoring
The narrow FOV can support industrial monitoring systems where a camera needs to observe a specific machine, production area or distant target without capturing an unnecessarily wide scene. Explore TOWIN’s Machine Vision Solutions for additional industrial imaging applications.
Remote Observation Systems
The compact M12×0.5 interface combined with a 70mm focal length makes this lens suitable for selected remote observation and embedded camera systems requiring focused, narrow-angle imaging.
