Application Scenarios & Compatible Devices
Target Applications & Industry Deployment
This 5MP fisheye lens is specifically optimized for wide-area situational awareness and situational monitoring where spatial constraints prevent multi-camera arrays. It excels in CCTV panoramic security surveillance, such as corridor ceilings, intersection monitoring, and smart video doorbells, capturing cross-room activities within a single frame. In industrial and automated settings, it functions as a highly reliable machine vision lens or FA lens, deployed on robotic arms, AGVs (Automated Guided Vehicles), and warehousing robots for navigation, obstacle avoidance, and macro proximity sensing down to 0.2 meters. Furthermore, its lightweight 22.9mm T.T.L. makes it a premier choice for Drone & UAV lenses, providing drone pilots and autonomous mapping software with a stable, sweeping layout of the terrain below.
Hardware Compatibility List
- Sensor Compatibility: Optimized for large-format sensors up to Max ø8.0mm, perfectly matching 1/2.5″, 1/2.7″, and 1/2.8″ image sensors, including Sony IMX347 and Aptina MT9P031.
- Surveillance Systems: Fully compatible with Hikvision, Dahua, and Tuya Smart IoT low-profile panoramic IP camera modules.

Frequently Asked Questions
- Q: Does this 2.5mm lens have an integrated IR Cut Filter (IRCF)?A: Yes, the lens features a 6G+IRCF structure, which includes a built-in Infrared Cut Filter to block unwanted IR light during the day, ensuring accurate color rendering for your security or vision system.
- Q: Will this M12 lens fit a standard C-mount or CS-mount camera?A: This is natively an M12x0.5 thread lens (S-mount). To use it with a C-mount or CS-mount industrial camera, you will need a standard M12-to-CS mount mechanical adapter.
- Q: How severe is the image distortion on this lens?A: The optical distortion is rated at <-68%. Because this is an ultra-wide fisheye lens designed for panoramic coverage, this barrel distortion is intentional to capture the extreme 186° field of view. Images can be digitally dewarped via software if straight lines are required.
- Q: What is the Minimum Object Distance (M.O.D.) for focusing?A: The Minimum Object Distance is 0.2 meters (7.87 inches), allowing it to capture sharp images of objects that are positioned very close to the lens module.
- Q: Can this lens handle outdoor weathering and temperatures?A: Absolutely. Built with a 6G (6 all-glass layers) optical design, it avoids the thermal focus shift common in cheap plastic lenses, ensuring consistent sharpness across outdoor security and drone applications.
- Q: Is this lens compatible with the Sony IMX347 sensor?A: Yes. It is fully compatible with the Sony IMX347 sensor, yielding a maximum diagonal field of view of 186° and a horizontal field of view of 176° at full 5MP resolution.
