Introduction: Meet the Hikvision DS-2CD2747G2HT-LIZS
The Hikvision DS-2CD2747G2HT-LIZS is a professional-grade outdoor IP dome camera that combines modern low-light imaging with flexible optics and smart analytics. Marketed as a 4 MP ColorVu motorised varifocal dome, it delivers 2688 × 1520 resolution from a large 1/1.8" progressive CMOS sensor, a motorised 2.8–12 mm F1.2 lens for remote zoom and focus, and hybrid illumination (white light plus IR) that produces full-colour images in very low-light conditions. Built to withstand outdoor conditions (IP67, IK10) and supporting PoE for simplified installation, this model is aimed at commercial and demanding residential surveillance applications where true-colour night detail and reliable analytics are priorities.

Detailed specifications and benefits
At the heart of this dome is a 1/1.8" progressive-scan CMOS sensor paired with a motorised 2.8–12 mm F1.2 lens. The combination provides flexible framing options: a wide horizontal field of view of roughly 114.6° at 2.8 mm for broad area coverage, narrowing to about 41.8° at 12 mm for licence-plate or face-detail focus. The F1.2 aperture helps gather light in low-light situations, improving signal-to-noise and enabling more usable colour information.
ColorVu smart hybrid lighting pairs white light with IR (850 nm) to deliver full-colour images even in very low light. Where pure starlight technology may produce monochrome images at night, ColorVu provides colour information that can be critical for identification, such as clothing, vehicle colour, or signage. The camera reports a minimum sensitivity down to 0.0008 Lux (F1.2, AGC on) and achieves 0 Lux with supplemental light, with an illumination range up to 40 m under the built-in light.
Efficient codecs are included to reduce bandwidth and storage demands. The camera supports H.265/H.265+ and H.264/H.264+, with support for ROI and SVC as well as multiple streams for monitoring and recording. On-board microSD storage (up to 512 GB) enables local recording and ANR (Automatic Network Replenishment) when connectivity is intermittent. Network-attached storage via NFS or SMB/CIFS is also supported.
AcuSense-based analytics provide people/vehicle classification and common intelligent event types such as line crossing, intrusion, tamper detection and region entry/exit. These analytics help reduce false positives compared with basic motion detection, making event-driven recording, alerts and search more accurate.
The unit supports industry-standard network and security features: ONVIF (Profiles S/G/T), HTTPS, 802.1X, TLS 1.1/1.2/1.3 and SRTP, and allows up to 32 concurrent users—important for larger sites or integrator access.
Designed for outdoor deployment, the camera has a metal housing rated IP67 for ingress protection and IK10 for impact resistance. Operating range spans from −30 °C to 60 °C and up to 95% non-condensing humidity. PoE (IEEE 802.3af Class 3) simplifies wiring and can supply power alongside data (max ~12.5 W), while 12 VDC is an alternative power option. Dimensions are compact for a domed design (Ø141 × 112 mm) with a weight of approximately 820 g.
Use cases and scenarios where this camera excels
The DS-2CD2747G2HT-LIZS is suited to any outdoor environment where colour detail at night, flexible framing and reliable analytics are needed. Typical scenarios include:
- Perimeter and entrance surveillance:ColorVu lighting helps capture vehicle colours and distinguishing clothing at gates, access roads, and building entrances even after dark.
- Car parks and loading yards:The motorised varifocal lens lets installers quickly set wide-area coverage or zoom into lanes and bays to monitor activity and incidents.
- Retail exteriors and forecourts:Full-colour night images aid incident investigation and loss prevention, while AcuSense helps reduce nuisance alarms from animals or foliage movement.
- Transport hubs and public spaces:Robust ingress protection and vandal resistance make the camera a reliable option for outdoor shelters, station approaches and pick-up zones.
- Professional security installations:Integrators specifying PoE cameras for enterprise projects will value ONVIF compatibility, advanced cybersecurity support and flexible storage options.
How it compares to similar products in the market
When sizing up competitors, consider three broad axes: low-light performance, analytics capability, and installation flexibility.
Low-light imaging:The ColorVu hybrid approach is distinct from sensors that rely solely on traditional IR or starlight technologies. Compared with basic IR-only cameras, ColorVu retains colour information after dusk, which can be decisive for identification tasks. Starlight-type cameras can provide impressive low-light sensitivity but often produce monochrome images as light levels fall; ColorVu avoids that compromise by adding controlled white light.
Analytics:AcuSense classification (people vs vehicle) places this model above basic motion-detection cameras in environments prone to false positives. For sites requiring advanced analytics like face recognition or license plate recognition, specialised models or external VMS/edge analytics may be preferable, but for general-purpose alarm reduction and event tagging, AcuSense is a practical balance of performance and cost.
Optics and installation:The motorised 2.8–12 mm varifocal lens provides greater installation flexibility than fixed-lens domes and simplifies commissioning because zoom and focus can be adjusted remotely. Compared to PTZs, a varifocal fixed dome offers a cost-effective middle ground—no moving pan/tilt but better detail control than a fixed lens.
Compression and storage:H.265+ optimisations and ROI/SVC support help reduce bandwidth and storage requirements compared with older H.264-only cameras, a factor that benefits multi-camera deployments and cloud or on-premises storage economics.
Customer feedback and installer impressions
There are no verified public customer testimonials included here. However, common feedback themes from professional installers and users of similar Hikvision ColorVu/AcuSense cameras include:
- Image quality:Many installers report that ColorVu provides usable colour detail at night that speeds incident resolution and evidence gathering.
- Ease of setup:Motorised zoom and PoE reduce install time compared with manual-focus models, especially on elevated mounts.
- Analytics value:AcuSense often reduces false alarms and improves the relevance of alerts sent to operators or security staff.
- Operational notes:Integrators recommend regular firmware updates and careful configuration of the white light behavior (scheduling/trigger rules) to avoid nuisance lighting or privacy concerns in sensitive areas.
Installation, compliance and practical considerations
For reliable outdoor performance, professional installation is recommended. Key considerations include correct mount selection and positioning to optimise field of view, PoE-powered switches or midspans with sufficient power budget, network segmentation and secure configuration (HTTPS, 802.1X, TLS) to reduce exposure, and ongoing firmware maintenance. Verify CE/UKCA and any local regulatory requirements with your supplier prior to purchase. The manufacturer specifies a maximum local microSD of 512 GB for on-board recording if network storage is not used.
Conclusion: Why choose the DS-2CD2747G2HT-LIZS?
The Hikvision DS-2CD2747G2HT-LIZS balances high-quality imaging, low-light colour capability and practical installation features in a robust outdoor package. Its 4 MP sensor delivers clear detail, the motorised 2.8–12 mm lens provides flexible framing without physical rework, and ColorVu hybrid lighting ensures colour information in conditions where ordinary cameras would switch to monochrome. AcuSense analytics help reduce nuisance alarms and make event-driven workflows more reliable, while H.265+ and ROI/SVC help control bandwidth and storage costs across multi-camera sites.
For commercial perimeters, car parks, retail exteriors and other outdoor areas where night-time colour and dependable analytics matter, this model is a compelling choice. Integrators will appreciate PoE support, ONVIF compatibility and the rugged IP67/IK10 construction. Consider network security, white-light configuration and maintenance processes in your deployment plan to get the best operational results.
Suggested retail guidance: the product is positioned in the professional mid-range; ask your supplier about current pricing, bulk discounts and warranty/service options to match project requirements.
