Precise Frame Adjustment – Varifocal Lenses

Varifocal lenses with manual iris adjustment are the most flexible solution for industrial cameras. They allow for manual and precise adjustment of the image zoom (focal length) and focus during camera installation.

This gives you full control over the frame – allowing the camera to see exactly what you want it to see, without needing to physically move the camera closer or further away.

Advantages of varifocal lenses:

• Flexibility: One lens (e.g., 2.8-12mm) covers the range from a wide angle to a significant zoom, making selection easier.
• Precision: Ability to accurately "frame" the monitored area, such as an entrance gate, door, or parking lot.
• Versatility: Ideal for situations where it is difficult to precisely determine the required fixed focal length before installation.

Zoom and focus adjustments are made manually using rings on the lens. These are the most frequently chosen lenses by professional CCTV installers.
