Introduction: what the Hikvision DS-2CD2746G2-IZS is and its key features
The Hikvision DS-2CD2746G2-IZS is a purpose-built 4 MP network (IP) dome camera that combines advanced low-light imaging, on-board deep‑learning analytics and flexible lens control into a vandal- and weather-resistant package. Key features include a 4 MP (2688 × 1520) sensor, DarkFighter low‑light technology with up to 40 m smart IR, a motorised 2.8–12 mm varifocal lens, and HikvisionAcuSense analytics for human/vehicle classification and perimeter detection. The unit supports PoE (802.3af) for simplified installation, H.265+ video compression for efficient storage and bandwidth use, and carries rugged IP66/IK10 ratings for exposed outdoor or high-risk indoor sites.
Detailed description of specifications and benefits
At the heart of the DS-2CD2746G2-IZS is a 1/3" progressive-scan CMOS delivering 4 MP resolution at up to 30 fps. The cameraA9s motorised 2.8 6 12 mm lens provides a horizontal field of view from about 108B0 down to 30B0, allowing installers or operators to remotely adjust between wide-area coverage and tighter, detail-focused views without physically accessing the device. The F1.4 aperture supports better light collection, improving image clarity in lower-light scenes.
DarkFighter technology and smart IR extend usable imaging into challenging lighting conditions: colour imaging is possible down to around 0.003 Lux (F1.4, AGC on) and the IR provides 0 Lux B/W capture up to approximately 40 m. Combined with 120 dB True WDR and image enhancement features like 3D DNR, HLC and BLC, the camera handles high-contrast scenes (for example, entrances with backlight, headlights or bright shop windows) while limiting noise in low-light situations.
A standout capability is HikvisionA9s AcuSense deep-learning analytics: the device can classify moving targets as human or vehicle, capture faces, and trigger perimeter events such as line crossing, intrusion and region entrance/exit. These on-board analytics significantly reduce false alarms from animals, leaves or weather, making alarm streams and recorded clips far more actionable.
For video efficiency, the camera supports H.265+/H.265 and H.264 compression with triple-stream output—helpful when integrating with NVRs, VMS or cloud services while balancing storage and network constraints. Local storage is supported via microSD (datasheet references up to 256 GB; some documentation lists 512 GB depending on firmware/variant—confirm the maximum supported capacity with the supplier or manufacturer). The device is ONVIF Profile S/G/T compatible for broader system interoperability.
Network connectivity is standard RJ45 10/100 Mbps and the camera supports common security controls (TLS/HTTPS, IPv6). PoE (802.3af) simplifies installation by permitting power and data over a single cable; the camera can also use 12 V DC as an alternative. Power draw is modest (approx. 10.5 612.5 W max).
Designed for exposed installations, the housing meets IP66 weatherproofing and IK10 impact resistance. Operating temperature spans from 60 B0C to 60 B0C with up to 95% non-condensing humidity tolerance, suiting a wide range of climates and demanding outdoor environments.
Use cases and scenarios where the camera excels
- Retail and hospitality:The combination of 4 MP detail, motorised varifocal lens and AcuSense analytics makes this camera well suited for storefronts, entrances and point-of-sale areas. Operators can remotely adjust the FOV to monitor queueing or focus on specific counters, while human/vehicle filtering reduces nuisance alerts.
- Perimeter and site security:For business parks, schools or light industrial perimeters, the cameraA9s long-range IR, True WDR and reliable classification help detect and verify intrusions in day/night conditions. IK10 vandal resistance adds resilience on lower poles or exposed mounting points.
- Commercial properties:Office campus entrances, car parks and loading docks benefit from the flexible lens and analytics. The device provides a balance of situational awareness (wide-angle views) and detail capture (zoomed views for license plates or faces when positioned correctly).
- Critical infrastructure and transport hubs:Where false alarms must be minimised and reliable low-light performance is required—such as station entrances or perimeter fencing—AcuSense classification and DarkFighter imaging deliver practical advantages.
- Systems integrator deployments:The DS-2CD2746G2-IZS is tailored for installers needing ONVIF compatibility, PoE-powered simplicity and remote lens adjustment during commissioning and fine-tuning of coverage.
Comparisons with similar products on the market
When choosing a camera in this class consider three main axes: image quality, analytics capability, and environmental robustness. The DS-2CD2746G2-IZS competes favourably in all three, particularly where on-device deep-learning analytics are required rather than relying solely on NVR-side analysis.
Compared with fixed‑lens 4 MP domes, the motorised varifocal lens is a major operational advantage: installers can adapt the field of view post-install without physical adjustments, saving time and reducing ladder work. Against higher-resolution alternatives (e.g., 8 MP models), the 4 MP sensor represents a cost-effective compromise—delivering sufficient detail for many surveillance tasks while lowering bandwidth and storage requirements.
Against rival brands, similar feature sets exist (low-light variants, motorised lenses and analytics). What often differentiates choices are the specifics of analytics implementation, ecosystem compatibility and after-sales support. HikvisionA9s AcuSense has a track record of improving alarm accuracy in many deployments; however, integrators should evaluate how it performs under local scene characteristics and confirm interoperability with chosen VMS/NVR solutions, especially in environments with mixed manufacturer devices.
Customer feedback and reviews
While individual reviews vary by installation and expectations, common themes from installers and end users evaluating this camera type include:
- Positive notes on low-light performance: DarkFighter imaging often yields usable colour images in low-light conditions where standard cameras would switch to B/W early.
- High appreciation for motorised varifocal functionality: the ability to remotely adjust focal length during commissioning and after installation is frequently cited as a major time-saver.
- Analytics value: AcuSense human/vehicle classification is typically praised for reducing false alarms, although integrators stress the importance of scene tuning and firmware currency for best results.
- Robustness in outdoor installations: IP66 and IK10 ratings are seen as important for exposed sites, though correct sealing and cable management are repeatedly recommended to maintain ingress protection.
Note: exact opinions will depend on firmware version, scene calibration and the specific unit supplied. Confirm warranty and supplier support terms at point of purchase.
Conclusion: why this camera is a strong choice
The Hikvision DS-2CD2746G2-IZS offers a compelling blend of image quality, low-light capability, flexible optics and on-board deep-learning analytics in a rugged dome design. For projects that require reliable human/vehicle classification to reduce false alarms, combined with the convenience of motorised varifocal control and PoE-powered installation, this camera represents a practical mid-range solution.
With a suggested retail price around 249 (check your local currency and supplier pricing), it sits in a segment that balances performance and cost. System designers and installers should confirm microSD capacity limits, firmware variant details and compatibility with their chosen NVR or VMS. When specified and commissioned correctly, the DS-2CD2746G2-IZS is well suited to retail, perimeter, commercial and transport applications where dependable day/night imaging and actionable alerts are priorities.
