Detailed specifications and benefits

This section breaks the camera's technical capabilities into practical benefits so you can judge how it will perform in real installations.

• Sensor:1/1.8" progressive-scan CMOS delivering 4 MP (2688×1520) at up to 25/30 fps. Benefit: higher resolution across a wider field of view enables better identification of people and objects without needing an extremely long focal length.
• Minimum illumination & DarkFighter:Colour to 0.0008 Lux (F1.2, AGC ON) and true B/W with IR to 0 Lux when needed. Benefit: exceptional low-light performance maintains situational awareness after dusk and in poorly lit areas, reducing the need for auxiliary lighting.
• WDR 120 dB:Wide dynamic range helps balance bright and dark areas in scenes with contrast, such as entrances with backlighting.
• Compression:H.265/H.264 with H.265+ enhancements, multiple streams, ROI and SVC. Benefit: efficient bandwidth and storage use while preserving critical detail for forensic review.

• Motorised 2.8–12 mm varifocal, F1.2:Wide-angle 114.6° to narrower 41.8° horizontal field of view. Benefit: remote focal length adjustment during commissioning or via an NVR/client simplifies setup and allows operators to reframe without physical access.
• Pan/Tilt/Rotate:Pan 350°, Tilt 0–85°, Rotate 350°. Benefit: near-complete orientation flexibility inside the dome for precise coverage of complex scenes like parking lots, perimeters and building façades.

• Human & vehicle classification:Deep-learning algorithms classify triggers to reduce false alarms from animals, leaves or weather. Benefit: fewer nuisance alerts and faster response to genuine security events.
• Perimeter protection & face capture:Line crossing, intrusion, enter/exit detection and supported face capture provide targeted alert types for different security policies.

• Built-in dual-array microphone and 2 W speaker:Enables two-way audio and pre-recorded or live deterrence messages. Benefit: active deterrence can sometimes stop incidents before escalation.
• Strobe/siren (SL model) and alarm I/O:Strobe and siren add visual/audible deterrence while alarm inputs/outputs let the camera integrate with third-party sensors and triggers.

• On-board storage:microSD up to 512 GB and support for ANR/NAS. Benefit: local buffering during network outages and flexible retention strategies.
• Power:12 VDC or PoE+ (IEEE 802.3at), ~16–18 W max. Benefit: PoE+ simplifies cabling for networked deployments and ensures sufficient power for motorised operation and deterrent features.
• Ingress & impact resistance:IP66 and IK10 rated metal housing. Benefit: reliable outdoor operation in rain, dust and against vandal attempts.
• Operating range:−30 °C to 60 °C, making it suitable for many harsh environments.

Use cases and scenarios where this camera excels

The DS-2CD2746G2H-IPTRZS2U/SL is built for installations that need clear video, intelligent alarms and flexible framing across medium to large outdoor scenes. Typical use cases include:

• Commercial car parks and multi-level parking areas:Wide-angle coverage at short focal lengths to monitor many bays, with the ability to zoom into incidents. Human/vehicle classification reduces alarm noise from moving foliage or weather effects.
• Retail and shopping centre exteriors:Monitoring entrances, loading zones and pedestrian flows. Active deterrence can be used to warn would-be thieves or loiterers in targeted areas.
• Office and industrial perimeters:Perimeter intrusion detection combined with PTZ framing adjustments helps verify alarms and capture useful forensic video before and after events.
• Transport hubs and critical infrastructure:DarkFighter low-light capability and face capture are valuable for operations that run 24/7 and require good human identification in low illumination conditions.
• High-end residential and estates:A single intelligent dome can replace multiple fixed cameras thanks to its motorised zoom and broad field of view, while deterrent features add a psychological barrier to intrusion.

Comparisons with similar products on the market

When choosing a motorised dome in the 4 MP class, consider how the DS-2CD2746G2H-IPTRZS2U/SL stacks up against typical alternatives.

• Compared with fixed-lens AcuSense cameras, the PTRZ dome adds remote framing and zoom flexibility, reducing the need to install multiple cameras to cover varied areas. The /SL variant further adds built-in strobe and siren for integrated deterrence.
• Higher-end Hikvision PTZ domes may offer longer optical zoom ranges or faster slewing but at higher cost and often with a larger physical footprint. The DS-2CD2746G2H is a compromise that provides motorised zoom and wide coverage while keeping a compact dome form factor and simpler wiring.

• Axis and some European brands emphasise low-latency streaming, robust cybersecurity features and long product lifecycles. Axis models with similar optics may carry premiums for brand and certain platform integrations.
• Dahua offers comparable feature sets in motorised domes (varifocal lenses, analytics and IR). Differences often come down to software ecosystems, analytics performance in real environments and local support/warranty terms.
• Important differentiators for the Hikvision model are the DarkFighter low-light performance and the AcuSense classification algorithm. Buyers should match analytics reliability, integration needs (ONVIF/Hikvision ecosystem), and procurement rules in their region.

Customer feedback and reviews

Public testimonials for this exact SKU may vary by region and reseller. Below are representative themes commonly reported by installers and end users of Hikvision AcuSense motorised domes. These are generalized observations rather than verbatim customer quotes, intended to give a practical sense of real-world experience.

• Positive themes:Installers praise the motorised varifocal for simplifying commissioning and the DarkFighter sensor for producing colour images in very low light. Security managers often highlight reduced false alarms thanks to AcuSense classification, and the integrated deterrent features are noted as useful when coordinated with site response policies.
• Considerations reported:Some integrators caution that PoE+ budget must be checked before installation due to the camera's higher power draw when using motorised movement and deterrent outputs. Others advise verifying local procurement or regulatory restrictions for Hikvision products in certain markets.
• Reliability and support:Organizations often report long-term satisfaction when cameras are installed by qualified technicians and when firmware is kept current. As with any networked device, good network design and secure credentials help avoid operational problems.

Conclusion — why this camera is a strong choice

The Hikvision DS-2CD2746G2H-IPTRZS2U/SL is a versatile, capability-rich motorised PTRZ dome that balances resolution, low-light performance and intelligent analytics for demanding outdoor security scenarios. Its 4 MP sensor and DarkFighter technology deliver clear evidence-grade video after dark, while the motorised 2.8–12 mm lens and near-full pan/tilt/rotate range give installers and operators the flexibility to frame scenes remotely. On-board AcuSense analytics reduce false alarms and sharpen event relevance, and active deterrence features allow immediate site-level responses to suspicious behaviour.

Durable IP66 and IK10 construction, support for PoE+, local microSD storage and H.265+ compression make the camera practical for real-world deployments where reliability, bandwidth and storage efficiency matter. When compared to fixed-lens models or higher-end PTZs, this dome occupies a useful middle ground: more flexibility than a fixed camera but more compact and cost-effective than a full PTZ turret with long-range optics.

Before purchase, verify local regulations regarding procurement and use of Hikvision equipment, confirm CE/UKCA and warranty terms with the supplier, and ensure your network and PoE+ infrastructure can support the camera's needs. With those checks in place, the DS-2CD2746G2H-IPTRZS2U/SL is well suited for commercial, industrial and high-end residential sites that require intelligent detection, effective low-light imaging and integrated deterrence in a rugged outdoor package.

Note:Suggested retail pricing and availability vary by region and reseller. Product warranty is typically three years; confirm exact terms with your supplier prior to purchase.
