Introduction: Meet the Hikvision DS-2CD2647G3-LIZSY
The Hikvision DS-2CD2647G3-LIZSY is a 4 MP outdoor IP bullet camera from Hikvisions ColorVu/Pro family designed to deliver clear, full-colour images around the clock. Combining a 1/1.8" progressive-scan CMOS sensor, a motorised 2.8012 mm F1.2 varifocal lens and Smart Hybrid Light (white LED plus IR), this model aims to solve the common trade-off between night-time visibility and scene context. On-board deep-learning analytics, two-way audio with a dual-microphone array and active deterrence features (strobe and audio alarm) make the camera well suited for perimeter protection, entrances, car parks and other exterior surveillance needs.

Detailed specifications and practical benefits
At the heart of the DS-2CD2647G3-LIZSY is a 1/1.8" progressive-scan CMOS sensor capable of 4 MP resolution (2688D7 1520). The larger sensor size and fast F1.2 varifocal lens allow more light to reach the sensor, improving low-light performance and depth of field. The motorised 2.8012 mm lens lets installers remotely adjust focal length and focus without physically accessing the camera, speeding up commissioning and enabling precise framing of critical areas.
Hikvisions ColorVu 3.0 technology provides continuous colour imaging in very low light. With a quoted minimum illumination of 0.0005 Lux (F1.2, AGC ON) and "0 Lux with light," the camera retains colour detail that IR-only systems commonly lose. The Smart Hybrid Light system integrates white LEDs and IR LEDs, supplying up to 60 m of supplemental illumination when needed. The practical benefit is clearer identification of clothing, vehicle colours and scene context at night, which is often critical for investigations and live monitoring.
Support for H.265 and H.264 compression (including H.265+/H.264+ variants) reduces bandwidth and storage requirements without compromising image quality. Image processing features such as WDR, 3D DNR, BLC/HLC and ROI allow the camera to handle high-contrast scenes (for example, a bright entrance with shadowed periphery) and optimise storage usage by prioritising important regions in the frame.
On-board deep-learning analytics provide person and vehicle classification, helping to filter out irrelevant motion and reduce false alarms triggered by animals, foliage or weather. When an alarm event is detected, the camera can trigger active deterrence: a visible strobe and an audio alarm. This combination enables immediate, automated response to suspicious activity, potentially preventing incidents before escalation.
The camera includes a dual-microphone array with environment noise filtering and two-way audio via an integrated speaker. Audio codecs supported include G.711, G.722.1, G.726, MP2L2, PCM, MP3 and AAC-LC. Network protocols are comprehensive (TCP/IP, HTTP/HTTPS, RTSP, ONVIF S/T/G, IPv6, 802.1X), making the unit interoperable with many VMS/NVR systems. Local storage via a microSD slot provides redundancy (resellers note support up to 512 GB), while PoE simplifies cabling for power and data over a single run.
With IP67 weatherproofing, IK10 vandal resistance and NEMA 4X anti-corrosion listing, the camera is built for exterior use in harsh environments, from coastal sites to industrial yards. Operating specifications spanning -30 °C to 60 °C and up to 95% non-condensing humidity mean reliable performance where temperature extremes are expected.
Use cases and scenarios where the camera excels
- Perimeter and gate security:Wide field of view at the 2.8 mm end and telephoto reach at 12 mm make the camera suitable for both broad perimeter monitoring and focused observation of gates or access points.
- Car parks and vehicle screening:ColorVu colour imaging lets security teams capture vehicle colours and plate backgrounds more reliably at night than IR-only cameras. The vehicle classification analytics help filter events to those that matter.
- Retail exteriors and shopfronts:Two-way audio and active deterrence are useful at retail entrances and loading bays to interact with or deter suspicious visitors.
- Industrial sites and utility yards:Rugged ratings (IK10, IP67, NEMA 4X) make this model suitable for corrosive or impact-prone locations where equipment resilience is essential.
- Residential estates and gated communities:High-resolution colour imaging and audio support for remote interactions increase situational awareness for security staff and management.
How it compares to similar products
A number of factors distinguish the DS-2CD2647G3-LIZSY from both lower-end and premium alternatives:
- Compared with 2 MP/4 MP fixed-lens cameras:The motorised varifocal lens offers flexibility in the field and remote adjustment, reducing installation time and the need for repeat site visits. The ColorVu system gives a real advantage over IR-only units when colour detail at night is important.
- Compared with higher-resolution models (6 MP+):Higher-resolution cameras deliver more pixels for cropping and long-range identification, but they increase bandwidth and storage demands. The 4 MP balance in this model tends to be a practical compromise for many sites: sufficient detail with more efficient resource use.
- Compared with rival brands:Competing products may offer similar optics or illumination features, but Hikvisions integrated ColorVu and on-board deep-learning analytics provide a well-integrated package. When choosing, consider factors such as VMS compatibility, data protection requirements and local support/service availability.
- Motorised vs manual varifocal:Motorised control is a convenience and operational advantage, particularly for inaccessible mounting points or sites where camera coverage needs to be tweaked remotely.
Customer feedback and reviews
Across installer and end-user feedback channels, this family of Hikvision ColorVu cameras typically receives positive comments for night-time colour performance, ease of framing with the motorised lens and the deterrence value of the strobe and audio features. Representative observations include:
- "Colour at night is a real step up from our old IR units; we can now read shirts and car colours in live view."
- "Remote lens adjustment saved us two site visits during commissioninga real time-saver for our team."
- "Built toughwe mounted several near the coast and they held up to salt spray and storms."
Some installers note the importance of checking PoE class, power budgets and the official datasheet for exact power and connector variants before ordering to ensure compatibility with existing infrastructure.
Conclusion: Why choose the DS-2CD2647G3-LIZSY?
The Hikvision DS-2CD2647G3-LIZSY is a versatile and rugged outdoor bullet camera that balances image quality, low-light colour performance and practical deployment features. Its 4 MP sensor provides clear detail while the motorised 2.8012 mm F1.2 lens and ColorVu 3.0 illumination make it particularly strong for nighttime situational awareness. On-board AI analytics reduce false alarms, and active deterrence tools (strobe and audio) give security teams options to respond automatically to incidents.
For organisations seeking reliable perimeter, car park or storefront surveillance with effective night-time colour capture and remote adjustment capability, this camera is a compelling choice. The suggested retail price sits at approximately $399, representing a mid-range investment for commercial-grade capability and ruggedised construction. Always consult the official datasheet and a qualified installer for wiring, power and site-specific configuration to get the best results from the camera in your deployment.
