Introduction to the DS-2CD2E43G2-U 4MP AcuSense Mini Dome and its key features
DS-2CD2E43G2-U — 4 MP AcuSense mini dome (4 mm)is a compact in‑ceiling/mini‑dome IP surveillance camera designed for discreet indoor security in retail, offices, corridors and reception areas. It combines a 4 MP sensor (2688 × 1520) with Hikvision's AcuSense deep‑learning analytics to classify human and vehicle targets, reducing common false alarms caused by lighting changes, small animals or moving objects.
Key features at a glance include high‑resolution imaging up to 30 fps, 120 dB WDR and 3D DNR for challenging light conditions, a fixed 4 mm lens with an approximately 84° horizontal field of view, on‑board microSD storage up to 512 GB, one‑way audio via a built‑in microphone, and flexible power options (PoE 802.3af or 12 VDC). The unit supports industry standards like ONVIF and common integrations such as Hik‑Connect and Hik‑Central.
Detailed description of specifications and benefits
The DS-2CD2E43G2-U uses a 1/3" progressive scan CMOS sensor to deliver crisp 4 MP video at up to 30 frames per second. With a minimum color illumination of 0.005 lux (F1.6, AGC ON), the camera performs well in dim indoor lighting — a common scenario in corridors, storerooms and late‑night retail. The 120 dB Wide Dynamic Range (WDR) combined with 3D Digital Noise Reduction (3D DNR) helps preserve details in scenes that include both bright and dark areas, while BLC/HLC options help manage strong backlight and highlight suppression.
This SKU ships with a fixed 4 mm lens (M12 mount) offering roughly an 84° horizontal field of view (≈100° diagonal). The tilt range of 0°–75° supports easy in‑ceiling adjustment so installers can fine‑tune coverage without changing the camera body or lens. The DORI guideline for the 4 mm lens gives a practical sense of detection and recognition ranges (Detect ≈85 m; Observe ≈34 m; Recognise ≈17 m; Identify ≈9 m), making the camera well suited to confined indoor spaces where single‑camera coverage is required.
AcuSense analytics are a primary selling point. Using deep‑learning models, the camera can classify motion events as human or vehicle and apply perimeter protection rules (line crossing and intrusion). This reduces time wasted on false alarms generated by moving vegetation, shadows or small animals and makes event notifications more relevant. For security teams and retailers, this increases operational efficiency when monitoring multiple feeds or when relying on event‑based recordings.
Efficient video encoding is supported with H.265/H.265+ and H.264/H.264+ codecs, enabling lower bandwidth and storage consumption without sacrificing image quality. Multiple streams and ROI (region of interest) support allow simultaneous live viewing and recording at different resolutions. Bitrate options range from 32 Kbps to 8 Mbps.
The built‑in one‑way microphone supports AAC, G.711 and MP3 codecs with noise filtering to improve audio clarity in indoor environments. For local storage, the camera accepts microSD/SDHC/SDXC cards up to 512 GB, and network storage options include NAS (NFS/SMB/CIFS) with ANR support to ensure recordings continue during temporary network outages.
Network connectivity is via a single RJ45 10/100 Mbps port with PoE (802.3af) support, simplifying installation in ceilings where power outlets may be limited. Power consumption is low — around 3.2 W on 12 VDC and approximately 4.2 W when powered over PoE — making it energy efficient for multi‑camera deployments. The camera body is plastic with dimensions Ø93.9 × 117.5 mm and is intended for indoor use (no IP rating specified). Operating temperature ranges from −10 °C to 50 °C, suitable for typical indoor environments.
The unit carries common certifications such as CE, FCC, UL and RoHS. Sellers should check packaging for UKCA if deploying in the UK. On the software side, the camera supports ONVIF Profile S/G for interoperability with third‑party NVRs and VMS, and integrates natively with Hikvision services such as Hik‑Connect, iVMS and Hik‑Central for centralized management and cloud features.
Use cases and scenarios where the camera excels
- Retail stores:Mounted in ceilings above aisles, POS areas or entrances, the camera provides high‑resolution coverage and human detection to reduce false alarms while capturing clear footage for loss prevention and customer flow analysis.
- Office environments:Ideal for reception areas, corridors and shared spaces where discreet ceiling mounting preserves aesthetics. AcuSense analytics reduce nuisance alerts from lighting changes or HVAC‑driven shadows.
- Healthcare and clinics:Where privacy and reliable detection are important, the mini dome offers clear imagery and one‑way audio for monitoring waiting rooms or entrances without being overly intrusive.
- Education and campuses:For indoor hallways, common rooms and administrative offices, the camera balances resolution and analytics to identify relevant incidents while reducing false alarms from routine student movement.
- Small‑to‑medium enterprise deployments:Its PoE compatibility, low power draw and built‑in storage options make it easy to deploy in small businesses that lack centralized infrastructure.
Comparisons with similar products in the market
Within its category — compact indoor AI‑enabled dome cameras around the 4 MP class — the DS-2CD2E43G2-U competes on price, analytics and versatility. A few comparative points:
- Vs. higher‑end fixed domes (premium brands):Some premium vendors offer metal housings, higher PoE+ power budgets, IP-rated bodies and advanced onboard analytics. Those cameras may deliver better low‑light or day/night performance, but they typically come at a significantly higher price. The DS‑2CD2E43G2-U is positioned as an affordable option that still offers practical AI features.
- Vs. entry‑level non‑AI cameras:Traditional 4 MP non‑AI domes may be slightly cheaper but lack AcuSense‑style classification. For environments where reducing false positives matters (busy retail or variable lighting), the AcuSense model reduces operational costs associated with reviewing irrelevant alerts.
- Vs. rival brands with similar analytics:Other vendors (for example, manufacturers offering person detection or deep‑learning analytics) provide comparable capabilities. Differences often boil down to ecosystem and integration: Hikvision cameras will integrate natively with Hik‑Central/Hik‑Connect, while other vendors have their own platforms. Choose based on existing infrastructure, preferred VMS support and long‑term management needs.
Customer feedback and testimonials
While individual experiences vary, aggregate feedback from installers and end users for cameras in this class typically highlights:
- Reliable indoor image quality and sufficient detail for identification at typical office and retail distances.
