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-LERV025HC | 640x512 12μm Uncooled 25mm Motorized Lens IP Thermal Imaging Core | Vehicle & UGV Vision

640 25mm Motorized Lens IP Thermal Module | Wide-Angle Vision for UGV & Security

ZV-LERV025HC | Wide-Field Situational Awareness | Motorised Precision | AI-Ready

Command Your Surroundings

The 25mm motorised lens delivers an expansive 17.4° × 14° field of view—optimised for real-time situational awareness in dynamic environments. Ideal for driver vision enhancement (DVE) and mobile robotics navigation where peripheral threat detection and obstacle avoidance are critical.

Clarity That Algorithms Trust

Pixel-sharp thermal imagery at 1080p output ensures reliable AI analytics performance. Consistent focus across the wide field eliminates blind spots that compromise automated detection in perimeter security and autonomous operations.
