Introduction: Meet the DS-2CD3146G2-ISU (2.8mm)(H) — 4MP AcuSense Fixed Dome
The DS-2CD3146G2-ISU is a compact, metal-bodied IP network camera designed for reliable indoor and outdoor surveillance. Branded as a 4MP AcuSense dome with a 2.8 mm fixed lens, it pairs Hikvisions DarkFighter low-light imaging with AcuSense deep-learning classification to deliver clear 2688 1520 video while reducing false alarms. Rugged IP67 weatherproofing and IK10 vandal resistance make it suitable for exposed installations, while PoE, onboard microSD storage (up to 512 GB), HDMI output and third-party app support (HEOP) broaden integration options.

Detailed specifications and benefits
The DS-2CD3146G2-ISU uses a 1/3" progressive-scan CMOS sensor delivering 2688 1520 resolution. The fixed 2.8 mm F1.4 lens provides an approximately 101 horizontal field of view, making it well suited to corridor, entrance and small-to-medium area coverage without the need for frequent repositioning. Low-light performance is a standout: DarkFighter technology produces usable colour images at just 0.003 Lux, and the cameras Smart IR (850 nm) extends surveillance to about 30 m at night when illumination is required.
Advanced image processing features such as 120 dB True WDR handle scenes with direct sunlight or backlighting, preserving detail in both shadows and highlights. Multiple compression formats (H.265+, H.265, H.264+, H.264) reduce bandwidth and storage needs while maintaining image quality. The camera supports up to four video streams and can record at up to 25/30 fps in regions with those frame rates, with bit rates configurable between 32 kbps and 8 Mbps for optimized network use.
AcuSense classification separates human and vehicle targets from other motion events, dramatically reducing nuisance alerts triggered by foliage, small animals, or lighting changes. The cameras AI compute capability (1.5 TOPS) and platform memory (system memory and Smart RAM) support robust on-device analytics as well as HEOP for third-party app integration. For installers and operators, this means more accurate alarms and better use of operator time and storage resources.
Onboard audio I/O (1 in / 1 out) and alarm I/O (1 input / 1 output) enable local event-triggered actions like sirens, recorded announcements or external sensor integration. An HDMI output (720p/1080p options) allows for local display. Network compatibility includes ONVIF S/G/T, HTTPS/TLS, and 802.1X, making the camera compatible with a wide range of VMS and NVR solutions for flexible deployment.
The unit supports PoE (IEEE 802.3af, Class 3) and 12 VDC power, drawing a maximum of approximately 10 W when powered by PoE. For storage, microSD/microSDHC/microSDXC cards up to 512 GB are supported, plus NAS options via NFS and SMB/CIFS with ANR. Physically, the camera is a compact Ø 119 90 mm dome weighing ~440 g and is rated for -10C to 40C operation. The metal housing provides IP67 ingress protection and IK10 impact resistance, ideal for exposed or public-facing locations.
Where this camera excels: practical use cases
The DS-2CD3146G2-ISU is versatile and suited to many common surveillance scenarios:
- Perimeter and boundary monitoring:IP67 weatherproofing and IK10 vandal resistance make the camera durable for perimeter fences, gates and compound edges, while AcuSense reduces false alarms from wind-blown vegetation.
- Car park and driveway surveillance:The combination of 4 MP resolution, wide field of view and human/vehicle classification ensures vehicles and people are captured with enough detail for recognition and incident verification.
- Retail and entrance monitoring:DarkFighter low-light performance keeps color images in dimly lit entryways, and AcuSense helps isolate human activity from benign motion.
- Transit hubs and public areas:Robust housing plus local audio/alarm options support interactive responses to incidents in busy, semi-public spaces.
- Integrator and system deployments:ONVIF and HEOP compatibility simplify integration into third-party VMS and analytics ecosystems, making it attractive to installers and integrators.
Comparisons with similar cameras on the market
When evaluating mid-range dome cameras, buyers typically compare three factors: image quality, analytics accuracy, and environmental robustness. The DS-2CD3146G2-ISU sits competitively across these axes.
Compared with older Hikvision models lacking AcuSense, the DS-2CD3146G2-ISU offers significantly fewer false alarms thanks to deep-learning human/vehicle discrimination. Image quality and low-light performance are also upgraded with DarkFighter and True WDR, which can be decisive for installations with mixed lighting conditions.
Competitors such as Dahuas WizSense series deliver similar human/vehicle detection and low-light capabilities. Differences often come down to user interface, integration, and ecosystem specifics: Hikvisions HEOP and ONVIF support make this camera easy to integrate into many third-party systems. Performance in the field—accuracy of classification, false alarm rates, and low-light color fidelity—will be comparable for good implementations, but regional support, firmware updates and partner ecosystem can affect the final choice.
Premium brands often lead on features such as advanced optics, extreme thermal ranges, and longer official warranties. The DS-2CD3146G2-ISU, however, delivers strong value with high-resolution imaging, capable AI, and excellent ingress/security ratings at a lower price point. For many commercial and light-industrial deployments the value proposition is compelling unless a specialized premium feature is required.
Price and value proposition
Suggested retail pricing is listed at149.00(check with your retailer for currency and local pricing). The provided cost price is113.78.

For real-world validation, ask your supplier for reference installations or seek online reviews specific to the DS-2CD3146G2-ISU or closely related Hikvision AcuSense models.
Installation, compliance and practical considerations
Installation is straightforward: power via PoE simplifies cabling and centralized power management, while a 12 VDC option is available if PoE is not present. For reliability and warranty considerations, professional installation is recommended. Check local regulations and product labelling for CE/UKCA compliance and confirm operating temperature suitability for your site (rated -10C to 40C). Also plan for storage capacity when using high-resolution continuous recording; microSD cards up to 512 GB or networked storage (NAS) can alleviate local recording limitations.
