Why do I need a motorized focus lens?

If your application requires observing targets at different distances (e.g., a PTZ camera looking at a gate 50m away, then a fence 500m away), a motorized lens is essential to refocus for maximum sharpness.

Yes, the ZV-LERV series supports "One-Push Auto Focus" via the web interface or API, locking onto the sharpest image in milliseconds.

ZV-LERV100HC | 640x512 12μm 100mm Motorized Lens IP Thermal Module | Long Range Auto-Focus Core | for perimeter security system Integration

640 100mm Motorized Focus Thermal Imaging Module | 640x512 VGA Core

ZV-LERV100HC | Precision Remote Focusing for Long-Range Surveillance up to 2000m.

Pixel-Sharp at 2km+, Regardless of Climate

Unlike athermalised lenses, the motorised 100mm lens delivers Active Focus—actively compensating for thermal drift during extreme temperature swings (e.g., desert day/night cycles). Maintain crisp, reliable imagery at 2km+ ranges in harsh conditions across deserts, tundra, and coastal zones.

<1s Focus Response for Radar Slew-to-Cue

Engineered for radar-photonic integration: achieves target clarity in under one second upon radar cueing. Ideal for border surveillance, maritime patrol, and critical infrastructure where instant visual confirmation is non-negotiable.
