Hikvision DS-2CD2543G2-IWS Wi-Fi Product Overview
The Hikvision DS-2CD2543G2-IWS(2.8mm) is a 4MP AcuSense fixed mini dome network camera with 2.4GHz Wi-Fi connectivity. Its 1/3-inch progressive-scan CMOS sensor records at up to 2688 × 1520, while the fixed 2.8mm F1.6 lens provides a wide 104.3° horizontal field of view.
The camera supports IEEE 802.11b/g/n wireless networking at up to 300Mbps under compatible conditions, while retaining a wired 10/100Mbps Ethernet interface and PoE support. It also includes infrared illumination up to 30 metres, 120dB WDR, human and vehicle classification, a built-in microphone, external audio and alarm interfaces and memory-card support up to 512GB.
Key Benefits
-
Detailed 4MP video: captures up to 2688 × 1520 at up to 25fps in 50Hz mode or 30fps in 60Hz mode.
-
2.4GHz Wi-Fi: supports IEEE 802.11b/g/n wireless networking with a manufacturer-rated data rate up to 300Mbps.
-
Wired or wireless networking: includes Ethernet and PoE as well as Wi-Fi; a separate power connection is still required when Wi-Fi is used without PoE.
-
Wide fixed view: the 2.8mm lens provides a 104.3° horizontal field of view.
-
Night and backlight performance: 30m infrared and 120dB WDR support darkness and high-contrast scenes.
-
AcuSense classification: supported events can distinguish human and vehicle targets.
-
Built-in microphone and interfaces: integrated audio capture plus external audio and alarm connections.
-
Protected compact housing: IP67 weather resistance and IK08 impact resistance.

Wi-Fi Installation and Performance
The camera uses the 2.4GHz Wi-Fi band and still requires electrical power. It can be powered by 12V DC when connected wirelessly or by PoE when using Ethernet. The quoted wireless speed and range are manufacturer test-condition maximums; walls, interference, channel congestion, antenna orientation and access-point capability can reduce real-world performance.
Detection, Audio and Compatibility
AcuSense can classify human and vehicle targets for supported motion and perimeter events. The built-in microphone captures audio, while separate audio and alarm input/output interfaces support compatible external equipment. Hikvision does not state a built-in speaker for this model.
Confirm local Wi-Fi coverage, network security, NVR compatibility, PoE or 12V power, memory-card requirements and mounting accessories before ordering. Wi-Fi connectivity does not mean the camera operates without a power supply.
Frequently Asked Questions
