Upgrade your CCTV system with clarity and flexibility. The Hikvision HV5721D-12MPIR is a premium varifocal lens designed for 12-megapixel cameras.

Why choose this lens?
Fixed-focus lenses often limit what your camera can capture — either too wide or too narrow. With the HV5721D-12MPIR you get the best of both: flexible zoom, high resolution and refined exposure control. The result? Clearer images, better coverage and a lens that grows with your system.

Installation & setup tips
- Ensure your camera’s sensor size matches (1/2.8″ or 3/4″ compatibility) to avoid vignetting.
- Mount the camera securely, set live view, then adjust the zoom (5.7-21 mm) to frame the scene, followed by focus.
- Check the DC auto-iris input on your camera or controller to ensure the lens auto-adjusts exposure correctly.
- Use a C/CS adapter if your camera uses a C-mount rather than CS-mount to maintain proper focus distance.
- For outdoor use, install the lens inside a weather-proof housing and keep the lens clean with a lint-free cloth.
