Compact motorized-lens mini dome

DS-2CD2543G2-LIZS2UY product overview

The DS-2CD2543G2-LIZS2UY is a compact 4 MP mini dome that combines short-range motorized lens adjustment, Smart Hybrid Light, AcuSense person and vehicle filtering and dual-microphone audio. It is intended for entrances, corridors and compact exterior locations where a low-profile housing and post-installation framing adjustment are useful.

Core capabilities

Compact adjustable framing

The motorized 2.8-4 mm lens provides a limited but useful range for refining scene width after mounting.

Smart Hybrid Light

Compatibility and pre-order checklist

✓Confirm whether the LIZ2UY or LIZS2UY variant is required.
✓Validate the 2.8-4 mm framing range against the actual mounting distance.
✓Check NVR or VMS support for smart events, audio and alarm interfaces.
✓Calculate PoE load and local memory-card retention.
✓Confirm white-light use, audio policy and environmental exposure before commissioning.

Frequently asked questions

Is this a 2.8-12 mm varifocal dome?

No. The listed model uses a much shorter 2.8-4 mm motorized range. It is intended for framing refinement, not long-range optical zoom.

What is the difference between LIZ2UY and LIZS2UY?

The S suffix identifies additional interface functionality in the family. Confirm the exact audio and alarm requirements against the ordered variant.

Does Smart Hybrid Light always turn on white light?

No. Behavior depends on the configured lighting mode and event rules. Select the mode that matches the site and local light restrictions.

Can it record without an NVR?

The camera supports local memory-card recording, but system features, retention and event management should be planned against the complete deployment.

Related planning resources

Compare network camera collection, review network video recorders, plan with network transmission equipment, or use the IPC and NVR matching guide.
