Can I really adjust the zoom from my phone after installation?

Yes. Dahua motorised varifocal cameras support remote zoom and focus adjustment via the DMSS app (iOS and Android) and the NVR's live view menu. No physical camera access required.

Varifocal vs PTZ — which do I need?

Varifocal sets a fixed zoom level for continuous monitoring of a defined scene. PTZ actively moves and follows targets in real time. Use varifocal when you know the scene; use PTZ when you need dynamic coverage across a large or unpredictable area.

What lens range does the 2.7–13.5mm cover?

Wide (2.7mm): full driveway, broad shopfront, wide room from ceiling. Tight (13.5mm): long corridor, car park lane entry, licence plate capture at 15–20m. Everything in between is adjustable remotely.

Is there a varifocal camera for coaxial cable sites?

Yes — the Dahua 4K Starlight HDCVI motorised dome delivers 8MP resolution and motorised zoom over existing coax. Works with Dahua HDCVI DVRs, no IP network required.

Which varifocal cameras support AcuPick footage search?

WizSense 3-series varifocal models support AcuPick when paired with a compatible Dahua AcuPick NVR. This lets you search recorded footage by clothing colour, vehicle colour, or vehicle type in seconds. See our Dahua dual-light camera kits for compatible varifocal bundle options.
