High-performance optics for professional CCTV installations. The Hikvision TV0550D-4MPIR offers a versatile 5–50 mm zoom range with DC auto-iris control, tailored for 4-megapixel cameras and CS-mount systems. Designed with IR correction, wide coverage and durable build, it is ideal for modern security setups across South Africa.
Why this lens makes a difference
Fixed lenses often limit your coverage and image clarity. This varifocal lens allows you to adjust framing on site — from wide area monitoring to tighter detail capture — while the auto-iris maintains consistent exposure under changing light conditions. For system integrators and serious users, that means better footage and fewer compromises.

- Corridors or access-ways where variable zoom is needed from broad coverage to closer detail.
- Upgrades for existing 4 MP CCTV systems where the original lens limits performance.
- Installers needing reliable optics for commercial builds in South Africa.
Installation & integration tips
- Ensure camera sensor spec matches (1/2.7″ or 1/3″) to avoid vignetting or poor coverage.
- Set live-view feed and adjust zoom and focus for optimal framing before final locking screws.
- Use a compatible auto-iris driver or camera input to fully benefit from DC auto-iris; otherwise expect manual iris behaviour.
- Lock zoom/focus screws after calibration to avoid drift from vibration or tampering.
- For outdoor setups, mount inside a weather-proof housing and keep lens clean using a micro-fibre cloth only.
Better optics mean better footage.
If you’re serious about surveillance performance, the TV0550D-4MPIR gives you control over field-of-view, exposure and clarity. Give your system the upgrade it deserves and monitor with confidence.
