- Security & IoT Systems: Seamless drop-in compatibility with Tuya smart home platforms, Hikvision/Dahua low-profile dome housings, and generic M12 camera modules.
- Embedded Hardware: Easily mounts onto Raspberry Pi high-quality camera assemblies, Jetson Nano developer boards, and multi-lens industrial USB camera setups.
- Customization Services: Available with modified total optical lengths (TTL), specialized anti-reflective (AR) coatings, or custom IR bandpass filter wavelengths upon bulk orders.
Designed for high-definition security and automotive surround-view applications.
Frequently Asked Questions
Q: Can this 4 Megapixel lens be paired with a standard 1080P (2MP) camera board?
A: Yes, absolutely. Using a premium 4MP rated lens on a lower-resolution 2MP or 720P sensor will significantly enhance overall image sharpness and edge-to-edge optical performance.
Q: Is the built-in IR cut filter removable for night vision applications?
A: No, this specific version features a permanently integrated 6G+IR cut filter config to ensure accurate daytime color reproduction. For specialized infrared night vision utilizing 850nm/940nm illuminators, we can provide a version without the IR cut filter upon request.
Q: What are the advantages of a 6G lens composition over cheaper alternatives?
A: The 6G configuration consists of 6 layers of premium precision glass. Unlike plastic lenses (like 2P or 2G2P) which expand and blur under heat, a 6G lens maintains strict structural integrity, preventing thermal defocusing in blazing dashboards or freezing winter weather.
Q: How do I adjust and lock the focus during my hardware assembly?
A: The lens features a manual M12x0.5 screw thread. You gently rotate the lens into your camera mount until the video output is sharp at your designated distance, then secure it in place using a standard M12 lock nut or optical adhesive.
Q: Does a distortion rate of <36% mean my video will look heavily warped?
A: For a 128-degree ultra-wide lens, a distortion of less than 36% represents a well-balanced wide view with moderate barrel effects. It captures a spacious panorama without the extreme circular “globe” distortion found in typical 170° fisheye lenses.
