Low-profile AcuSense mini dome family

DS-2CD2543G2-I(WS) product overview

The DS-2CD2543G2-I(WS) family is a compact 4 MP mini dome for discreet indoor or outdoor monitoring. Human and vehicle classification, a built-in microphone, fixed-lens choices and IR illumination support entrances, corridors and small commercial spaces, while the S and W suffixes identify interface and Wi-Fi options.

Core capabilities

Compact camera profile

The mini dome format fits entrances, corridors and low-ceiling locations where a large housing is undesirable.

Relevant event filtering

AcuSense classification supports human and vehicle targeting for motion, line-crossing and intrusion events.

Audio-ready family

All listed options include a microphone; IS and IWS variants add the specified audio and alarm interfaces.

Wired or Wi-Fi option

The W suffix identifies Wi-Fi capability, while wired Ethernet and PoE remain important variant checks.

Compatibility and pre-order checklist

✓Select the exact I, IS or IWS variant instead of relying on the family name alone.
✓Choose the 2.8 mm or 4 mm lens according to scene width and target detail.
✓For IWS, confirm Wi-Fi coverage, security policy and whether wired PoE is still preferred.
✓Check NVR or VMS support for AcuSense events, microphone audio and alarm interfaces.
✓Review audio privacy, memory-card retention, mounting and weather sealing.

Frequently asked questions

What do I, IS and IWS mean for this product family?

The base I variant provides the core camera functions, S identifies added audio and alarm interfaces, and W identifies Wi-Fi capability. Confirm the exact ordered variant.

Should I choose the 2.8 mm or 4 mm lens?

Choose 2.8 mm for a wider overview and 4 mm for a narrower view with more target detail at the same distance.

Does the camera record audio?

A built-in microphone is listed, but recording depends on configuration, recorder support and local privacy rules.

Is Wi-Fi always enabled on every variant?

No. Wi-Fi is suffix-dependent. Verify the IWS variant, regional radio requirements and site signal quality before relying on wireless connectivity.
