Introduction to the Hikvision DS-2CD2786G2-IZS(C)
TheHikvision DS-2CD2786G2-IZS(C)is an 8MP (4K) AcuSense DarkFighter motorised varifocal dome network camera designed for demanding commercial and premium residential surveillance. Combining high-resolution imaging with deep-learning analytics, low-light colour capability and a robust, weather- and vandal-resistant enclosure, this camera targets installations where image detail and reliable detection are essential. Key highlights include a motorised 2.8–12 mm lens, DarkFighter low-light performance, AcuSense human/vehicle classification and up to ~40 m of IR illumination.
Key features at a glance
- Resolution:8MP (3840 × 2160) 4K sensor for crisp, high-detail footage.
- Low-light imaging:DarkFighter technology for colour images down to 0.003 Lux.
- Motorised varifocal lens:2.8–12 mm, F1.4 with remote zoom and focus (approx. 108°–46° horizontal FOV).
- Analytics:AcuSense deep-learning features including human/vehicle classification, face capture and perimeter protection.
- Durability:IP66 weatherproofing and IK10 vandal resistance for outdoor use.
- Flexible power and storage:PoE (802.3af) or 12 VDC, local microSD up to 256 GB, NAS support.
Detailed specifications and benefits
- Sensor:1/1.8" progressive CMOS delivering 3840 × 2160 resolution. The larger sensor size and progressive readout help capture fine detail and reduce motion artifacts in busy scenes.
- Frame rate:Up to ~25 fps at 50 Hz (or 24–30 fps at 60 Hz) in 4K, suitable for smooth evidence-grade video without excessive bandwidth.
- Signal-to-noise ratio (SNR):≥ 52 dB, which contributes to cleaner images and better performance in mixed-light environments.
- Motorised varifocal 2.8–12 mm, F1.4:Remote zoom and focus let installers tailor the field of view on-site or from the control room without physical access to the camera. The fast F1.4 aperture admits more light for superior low-light image clarity.
- Field of view:Approximately 108° at the wide end to 46° at the telephoto end, making the camera versatile for both wide-area coverage and medium-distance identification tasks.
- Minimum illumination and IR:Colour operation down to 0.003 Lux (AGC on) and B/W to 0 Lux with IR active. The 850 nm IR with smart supplement light reaches to roughly 40 m, useful for extended night monitoring.
- True WDR 120 dB:Handles scenes with strong backlight or contrasting bright/dark areas so important subjects remain visible.
- Noise reduction:3D DNR reduces visual noise in low-light footage without blurring key details.
- Compression:H.265 / H.264 (and enhanced H.265+/H.264+ variants) to reduce storage and bandwidth demands while preserving image quality. Multiple configurable streams, ROI and SVC support enable optimized delivery to recorders and remote viewers.
- AcuSense deep-learning analytics:Automatic human/vehicle classification significantly reduces false alarms triggered by animals, weather or vegetation. Perimeter protection (line crossing, intrusion), and face capture add layers of actionable intelligence.
- Local and network storage:microSD/SDHC/SDXC up to 256 GB for on-device recording; NAS (NFS/SMB/CIFS) and ANR support for redundancy during network outages.
- Power:12 VDC ±25% (max ~10.5 W) or PoE 802.3af (max ~12.5 W). PoE simplifies installation by combining power and data on one cable.
- Protocols:ONVIF compatibility and native integration with Hikvision platforms such as Hik-Connect, iVMS-4200 and Hik-Central, enabling centralized management and recording.
- Ingress protection:IP66 for reliable operation in rain, dust and many outdoor conditions.
- Vandal resistance:IK10-rated housing for protection against impact and tampering in public-facing or exposed locations.
- Dimensions and weight:Ø153.5 mm × 133.2 mm; approx. 1080 g — compact for a dome of this capability yet substantial enough to deter casual tampering.
Use cases and scenarios where this camera excels
The DS-2CD2786G2-IZS(C) is designed for environments that demand high resolution, reliable analytics and robust physical protection. Typical applications include:
- Commercial campuses and retail sites:Use the 4K resolution and motorised zoom to monitor large storefronts, loading docks and car parks. AcuSense analytics help prioritize human and vehicle events and reduce nuisance alarms from animals or weather.
- Transportation hubs:Train stations, bus depots and airports benefit from the combination of wide-angle coverage and the option to zoom in for identification. Low-light DarkFighter performance and long-range IR are valuable during night operations.
- Perimeter and critical infrastructure:IP66 and IK10 ratings make it suitable for outdoor perimeter protection, while AcuSense rules and true WDR handle challenging lighting conditions at gates and entrances.
- Residential estates and gated communities:For premium residential deployments, the camera offers discrete dome styling with high-quality night imaging and face capture for visitor verification.
- Banking and financial facilities:Where identification and evidence-quality imaging are required, the 4K sensor and intelligent analytics provide clear recordings for investigations.
Comparisons with similar products in the market
Within the 4K varifocal dome category, the DS-2CD2786G2-IZS(C) competes on three main fronts: image quality, analytics, and ruggedness.
- Image quality:Many competitors offer 8MP sensors, but the combination of a 1/1.8" sensor and DarkFighter technology gives this Hikvision model an edge in low-light colour performance compared with standard low-light sensors that revert to monochrome earlier.
- Analytics:The AcuSense deep-learning suite is a differentiator for reducing false positives compared with older motion-only systems or those without specific human/vehicle classification. Competing brands offer similar AI-based features, but integration depth and tuning tools vary by vendor.
- Physical protection and installation:IP66 and IK10 are common for higher-end outdoor domes; where this model stands out is the motorised varifocal lens with remote control, which saves installation time compared with fixed-lens 4K domes that require physical access for focus and framing.
- Value:With a suggested retail price around $299, this model positions itself competitively against other 4K AI-enabled domes from global brands. Buyers should weigh feature sets, warranty, local support and platform compatibility when comparing models.
Customer feedback and typical reviews
While individual reviews vary by installation and expectations, installers and end users commonly report the following observations:
- Positives:Praised for excellent daytime and night-time image clarity, the convenience of motorised zoom and the effectiveness of AcuSense in cutting down false alarms in perimeter and entry applications. Integrators appreciate PoE support and ONVIF compatibility for smooth NVR integration.
- Constructive notes:Some users note the need for careful setup of analytics thresholds to balance sensitivity and false alarms, and that advanced features are best unlocked when integrated with Hikvision management platforms. As with any sophisticated camera, getting optimal results requires proper placement, configuration and network planning.
