One System, Every Range
The 35mm motorised lens delivers true depth-of-field flexibility—instantly refocus from near-field equipment inspection to far-field perimeter monitoring. Surpasses fixed-focus athermalised designs where operational versatility is non-negotiable.
Precision Input for Smarter AI
Algorithm-ready imagery with consistent edge-to-edge sharpness maximises AI intrusion detection accuracy. Eliminates the subtle defocus of fixed lenses that compromises analytics reliability—critical for automated security in dynamic environments.

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.
