Frequently Asked Questions
Q: Why does this lens have an optical distortion rating of <-18%?
A: This lens is an ultra-wide angle/fisheye lens. To achieve a massive 110° diagonal coverage in a compact design, a certain level of barrel distortion is optically necessary. This allows the camera to maximize tracking coverage and capture entire rooms or multi-lane road entryways, which can be easily corrected digitally if needed.
Q: What is the benefit of the 2G2P lens component structure?
A: The hybrid 2 Glass + 2 Plastic element construction balances cost and performance. The 2 glass elements provide high scratch resistance and thermal stability to prevent image defocusing under direct summer sunlight, while the 2 plastic elements utilize precision molding to correct optical aberrations.
Q: Will this lens maintain sharp focus during nighttime operation?
A: Yes. This lens features an integrated IR filter structure and specialized optical coatings designed to minimize focus shifts between visible light and infrared light. When paired with external 850nm or 940nm infrared LEDs, it delivers clear and crisp night vision.
Q: Can I use this 1/2.5″ format lens on a smaller 1/3″ sensor module?
A: Absolutely. It is fully backward-compatible. When installed on a smaller 1/3″ sensor, the image crop factor will reduce the field of view slightly (acting like a crop mechanism), but you will gain excellent center resolution with zero corner vignetting.
Q: How close can this wide-angle lens focus on a target?
A: The Minimum Object Distance (M.O.D.) is 0.1 meters (10 cm). This allows the camera module to capture extremely sharp images of nearby objects or hand-held IDs, which is essential for video doorbells and biometric access turnstiles.
Q: Is the F2.5 aperture suitable for outdoor low-light conditions?
A: Yes, an F2.5 aperture is relatively bright for an ultra-wide board lens. It permits a high volume of light transmission to the CMOS sensor, which reduces digital image noise and ensures bright, low-noise footage at dusk or in dimly lit hallways.
