Introduction to the Hikvision 4 MP ColorVu PTRZ Motorised Dome
Hikvision DS-2CD2747G2H-LIPTRZS2U/SL— marketed as the 4MP ColorVu PTRZ Outdoor Dome Camera — is a professional motorised dome IP camera designed for continuous, high-quality colour surveillance in outdoor environments. Combining a 4 MP sensor, a motorised 2.8–12 mm varifocal lens with remote pan/tilt/rotate/zoom (PTRZ) capability, hybrid illumination (IR + powerful white light), and on-board deep-learning analytics, this camera targets sites that need reliable detection, classification and visible deterrence around the clock.
Key highlights include full-colour low-light capture down to very low lux levels (and effectively 0 lux when white light is active), PoE+ for simplified installation, IP66 and IK10-rated housing for harsh outdoor conditions, and smart features such as face capture, person/vehicle classification and perimeter protection to reduce false alarms.
- Resolution:4 MP (2688 × 1520) at up to 30 fps for clear detail.
- Hybrid illumination:IR plus white-light supplement for 24/7 colour imagery and active deterrence.
- Motorised PTRZ:2.8–12 mm varifocal lens with remote control for fast framing and flexible coverage.
- Analytics:Deep-learning features including face capture, object classification and perimeter protection.
- Ruggedised:IP66 weatherproof and IK10 vandal-resistant body for outdoor deployments.
Detailed specifications and benefits
This camera packs a comprehensive specification set that balances image quality, smart functionality and site resilience. Below is a breakdown of the most important technical details and the practical benefits they deliver.
- Image sensor:1/1.8" progressive-scan CMOS delivering 4 MP resolution. Benefit: higher pixel density than many 2 MP devices, allowing readable detail at greater distances.
- Lens:Motorised varifocal 2.8–12 mm. Benefit: remotely adjustable field of view (≈114.6°–41.8° horizontally) simplifies commissioning and allows operators to fine-tune coverage without climbing ladders.
- Min. illumination / aperture:Max F1.2; colour ≈ 0.0028 lux at F1.2 and 0 lux when white light is active. Benefit: delivers meaningful, colour-identifiable images in conditions where typical cameras would be monochrome or unusable.
- Compression:H.265/H.265+ and H.264/H.264+. Benefit: efficient bandwidth and storage usage, especially over long-term recording.
- Streams:Up to 3 simultaneous (main / sub / third) for recording, viewing and analytics without reconfiguring the camera.
- WDR:130 dB. Benefit: improved detail in scenes with both bright and dark areas such as entranceways with backlighting.
- Hybrid IR + white light:Combined illuminators extending effective monitoring to roughly 40 m with white-light assistance. Benefit: white light provides colour at night and supports active deterrence (visible light + optional siren/strobe).
- Smart illumination:The camera can manage when to use IR vs white light, reducing nuisance lighting while preserving colour evidence when needed.
- Analytics:Face capture, person/vehicle classification and perimeter protection (line crossing, intrusion, region entry/exit). Benefit: proactive alerting and reduced false positives through target-type filtering.
- Audio & deterrence:Built-in dual-array microphone, speaker and alarm I/O (1 in / 1 out). Benefit: supports two-way audio, recorded audio evidence and live deterrence messages.
- Network security:ONVIF S/G/T, HTTPS, TLS 1.1–1.3, 802.1X. Benefit: integration flexibility and secure communications when deployed properly.
- Power:PoE+ (IEEE 802.3at) or 12 V DC. Benefit: PoE+ simplifies outdoor deployments by delivering power and data over one cable when combined with compliant switches.
- Storage:microSD up to 512 GB, NAS support (NFS/SMB), and ANR. Benefit: local fallback recording and flexible retention strategies.
- Build:IP66 and IK10 rated; dimensions Ø155 × 140.4 mm with ~820 g weight. Benefit: resilience to weather, dust and attempted vandalism typical of exterior camera installations.
Use cases and ideal scenarios
The DS-2CD2747G2H-LIPTRZS2U/SL is well-suited where continuous, colour-capable monitoring, flexibility of coverage and a robust exterior rating are required. Typical deployments include:
- Retail fronts and shoplines:Colour detail helps identify clothing, vehicle colours and signage; motorised zoom lets operators focus on till areas or entrances when incidents occur.
- Car parks and vehicle ingress/egress points:Person and vehicle classification reduces false alarms from shadows or animals while white light reveals plate and occupant details at night.
- Perimeter and fence lines:Combined analytics and perimeter protection for line crossing and intrusion, with active deterrence to discourage trespassers before escalation.
- Building entrances and public spaces:Wide horizontal field of view at the short end of the lens and the ability to zoom in remotely makes it flexible for both overview and incident investigation.
- High-end residential and small campus installations:Where owners want visible deterrence and high quality night-time colour imaging without sacrificing discrete installation options.
Installation notes: mount on a firm surface with adequate clearance for PTRZ movement, use IP-rated conduits or glands for outdoor cabling and ensure PoE supplies meet IEEE 802.3at to avoid underpowering the camera.
How it compares with similar products
Within the market, the DS-2CD2747G2H-LIPTRZS2U/SL occupies a niche between fixed varifocal cameras and full PTZ domes. Compared with fixed outdoor ColorVu models, it adds remote PTRZ capability so you can change framing and zoom without camera replacement. Against larger PTZ domes, it offers simpler mechanical movement focused on pan/tilt/rotate/zoom for targeted coverage while keeping a compact dome footprint.
Against competitor offerings from other major OEMs, the principal differentiators are Hikvision's ColorVu hybrid-light technology and integrated analytics at this resolution point. Some competing models may offer higher optical zoom ranges or different form factors; others might prioritise edge analytics or cloud-first workflows. Key decision factors are desired zoom range, analytics accuracy, integration requirements (ONVIF vs proprietary), and active deterrence features like built-in white light and speaker/siren.
From a cost perspective, with a suggested retail price around 329.00 (cost price 262.97 indicated), this camera aims to provide strong value for installations that need both continuous colour evidence and smart alarm reduction without moving to larger, more costly PTZ platforms.
Customer feedback and practical observations
While individual reviews vary by installation and expectations, common themes from installers and site managers for this class of device include:
- Positive remarks on night-time colour clarity when white light engages — provides immediate visual context that IR-only cameras cannot.
- Appreciation for the motorised lens and remote framing — reduces site visits for field-of-view adjustments and speeds commissioning.
- Noted benefits of on-board analytics in cutting down nuisance alarms, particularly for perimeter sites with busy backgrounds.
- Practical comments to ensure PoE+ power supplies to meet peak power use when white light and audio deterrence are active, and to keep firmware updated for security and feature enhancements.
If you are sourcing this camera for a specific project, consult installers familiar with local regulations and ensure integration testing with your VMS/NVR of choice.
Conclusion: why choose the Hikvision ColorVu PTRZ dome?
The Hikvision DS-2CD2747G2H-LIPTRZS2U/SL is a well-rounded outdoor surveillance camera that blends continuous colour imaging, a motorised varifocal PTRZ mechanism, rugged construction and useful analytics into a single compact dome. It excels where identification-level colour detail at night matters, where remote framing is valuable, and where perimeter analytics can reduce false alarms and focus operator attention.
For system designers and installers looking for an outdoor camera that reduces the need for multiple device types (deterrence, analytics, two-way audio) while remaining relatively straightforward to deploy via PoE+, this model offers a practical balance of capability and value. As always, validate power budgets, mounting details and VMS compatibility during planning to get the most from the camera on day one and over its operational life.
