Sharp at 1km+, Even in Harsh Climates
Unlike athermalised lenses, the 75mm motorised optic features Active Focus—actively correcting thermal drift during extreme temperature shifts (e.g., desert day/night cycles). Delivers pixel-sharp imagery at 1km+ ranges across deserts, highlands, and coastal environments.
<1s Response for Radar Slew-to-Cue
Rapid focus acquisition (<1 second) enables seamless integration with radar tracking systems. Instant visual confirmation upon cue—critical for border surveillance, maritime domain awareness, and perimeter protection.

FAQs
Q: Why do I need a motorized focus lens?
A: 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.
Q: Can it auto-focus?
A: Yes, the ZV-LERV series supports "One-Push Auto Focus" via the web interface or API, locking onto the sharpest image in milliseconds.
