Frequently Asked Questions
Q: What does “IR Corrected” mean and why is it beneficial?
A: Visible light and infrared light focus at different points on a sensor due to wavelength variations. An IR Corrected Lens uses specialized optical glass to bring both light types into the exact same focal plane, preventing blurry images when your camera switches to nighttime IR mode.
Q: Is the <-8% TV distortion suitable for security applications?
A: Yes. In surveillance and traffic management, wide coverage is prioritized over zero distortion. A profile of <-8% barrel distortion is standard for a 90° wide-angle layout, allowing the lens to capture broad, multi-lane road views or wide entryways.
Q: Can I use this M12 lens on a 1/3″ security sensor module?
A: Absolutely. This lens is fully backward-compatible with smaller formats such as 1/2.7″, 1/2.8″, and 1/3″ sensors. Using a smaller sensor will slightly crop the field of view, but you will achieve outstanding center clarity with absolutely zero corner vignetting.
Q: How does the F2.2 aperture improve performance at night?
A: An F2.2 aperture is quite large, meaning it allows significantly more ambient light to hit the CMOS sensor compared to restrictive F3.5 or F4.5 lenses. This reduces digital noise, speeds up shutter response, and delivers cleaner footage in low-light environments.
Q: Does this lens include a built-in IR-cut filter on the barrel?
A: To maximize day/night surveillance utility, this lens is designed without a permanent IR-cut block, allowing near-infrared light to pass through. It is highly recommended to pair this lens with a motor-driven IRC switcher on your camera board.
Q: What is the Minimum Object Distance (M.O.D.) for this model?
A: The M.O.D. is 0.3 meters (30 cm). This ensures that everything from 30 cm out to infinity remains beautifully sharp and detailed, making it perfect for tracking passing vehicles or pedestrians at varying distances.
