Hikvision 4MP ColourVu Motorised Varifocal Bullet Camera, Audio & Siren DS-2CD2647G3-LIZS2UY/SL

Introduction: Hikvision 4MP ColourVu Motorised Varifocal Bullet Camera

The Hikvision DS-2CD2647G3-LIZS2UY/SL is a 4MP outdoor ColourVu motorised bullet camera designed for continuous, high‑quality colour surveillance in challenging lighting conditions. Combining a large 1/1.8" progressive CMOS sensor, a fast F1.2 motorised 2.8–12 mm varifocal lens and Hikvisions Smart Hybrid Light system (white + IR), this camera delivers clear, full‑colour footage at night as well as strong daytime performance. It also integrates dual microphones, a speaker and a siren for two‑way audio and active deterrence, plus on‑board deep‑learning analytics such as person/vehicle classification and perimeter protection.

• 4 MP resolution(2688 1520) for detailed images.
• ColourVu + Smart Hybrid Lightfor full‑colour low‑light imaging with supplemental illumination to ~60 m.
• Motorised 2.8 12 mm F1.2 varifocal lensproviding an adjustable horizontal field of view from approximately 114.6 41.8.
• Built‑in audio and alarm: dual array microphones, speaker, siren and line in/out for two‑way communication and active alerts.
• Advanced video features: H.265/H.264 compression, WDR 130 dB, 3D DNR and EIS for stable, clean footage.
• Rugged outdoor build: IP67, IK10 and NEMA 4X ratings for reliable operation in harsh environments.
• Deep‑learning analyticsfor person/vehicle classification, face capture and perimeter protection.

• Sensor and resolution:1/1.8" progressive CMOS delivering 2688 1520 (4 MP). Benefit: higher pixel count for clearer identification of faces, license plates and small scene details compared with lower‑resolution 2MP cameras.
• Motorised varifocal lens 2.8 12 mm, F1.2:offers remote adjustment of field of view and focal length during installation, reducing time on ladders and enabling precise framing from a single mount point.
• Minimum illumination:colour 0.0005 Lux @ F1.2 (0 Lux with light). Benefit: retains useful colour information in very low ambient light when ColourVu and the white light are engaged.

• Smart Hybrid Light (white + IR):dynamically balances white LED and IR illumination to produce natural full‑colour images at night while extending detection range. Benefit: colour evidence after dark and less reliance on ambient street lighting.
• Supplement light range:up to ~60 m. Benefit: long reach for perimeter and parking area surveillance.

• Compression:H.265 and H.264 with H.264+ support. Benefit: reduced bandwidth and storage requirements without significant loss of image quality.
• WDR 130 dB, 3D DNR, EIS:Wide dynamic range for backlit scenes, noise reduction for clear low‑light images, and electronic image stabilization to reduce motion blur—useful for busy entrances and moving objects.
• Frame rate:Up to 25/30 fps (region dependent) for smooth motion capture.

• Built‑in dual array microphones, speaker and siren:enables two‑way communication and audible warnings. Benefit: verify incidents remotely and deter intruders in real time.
• Audio codecs:G.711, G.722.1, G.726, MP3, AAC‑LC for flexible integration with recording systems and NVRs.

• On‑board storage:microSD up to 512 GB for edge recording and redundancy if network connectivity is lost.
• Network:ONVIF S/T/G and common secure protocols (HTTPS/TLS), making the camera interoperable with many third‑party NVRs and VMS platforms.
• Power:12 VDC (max 14.5 W) or PoE IEEE 802.3at (Class 4, max 18 W) for flexible deployment and simplified cabling.

• Operating temperature:-30 60 C, and rugged IP67/IK10/NEMA 4X bodies for reliable outdoor use.
• Security features:HTTPS/TLS and user authentication help protect access to streams and device settings.

The DS-2CD2647G3-LIZS2UY/SL is well suited to a range of commercial and institutional deployments where high‑quality colour imaging and active deterrence are priorities:

• Car parks and perimeter security:Long supplemental light range and ColourVu make it easier to capture plate numbers and distinguish colours at night, while analytics reduce false alarms by classifying vehicles and people.
• Retail exteriors and storefronts:Two‑way audio and siren support loss prevention by allowing security staff to communicate with, warn or deter suspicious individuals instantly.
• Commercial campuses and industrial sites:Rugged ingress and impact ratings ensure reliable operation in exposed environments; motorised zoom enables flexible mounting and precise coverage from a single camera location.
• Critical infrastructure and transportation hubs:High dynamic range and analytics help detect intrusions, line crossings and suspicious activity across large outdoor zones.
• Remote or intermittently connected sites:Up to 512 GB local storage provides buffering and local retention if network links are unreliable.

When comparing the Hikvision ColourVu motorised 4MP bullet to other options on the market, consider several dimensions: low‑light colour capability, analytics, audio/deterrence features, durability and total cost of ownership.

• Vs. standard low‑light cameras (2MP/3MP Starlight models):ColourVus dedicated white light keeps images in colour at night where Starlight sensors often fall back to monochrome—useful for identifying clothing or car colours. The 4MP resolution also yields more detail than many 2MP units.
• Vs. rival manufacturers offering white‑light solutions:Competing models from other vendors (Dahua, Uniview) also offer white light and analytics; choice often comes down to platform compatibility (ONVIF and vendor VMS), firmware ecosystem and regional support. Hikvision typically offers a broad feature set and competitive pricing for the included analytics and audio features.
• Vs. higher‑end fixed‑lens or PTZ cameras:PTZs provide wider coverage but at higher cost and complexity. The motorised varifocal bullet offers a middle ground: remote optical framing and powerful analytics at a lower price point than PTZ while delivering focused, high‑quality images.

Below are common themes reported by installers and end users who choose ColourVu motorised bullets for outdoor surveillance (representative feedback):

• "Colour at night changed how we investigate incidents — we can now see car colours and clothing without relying on streetlights."
• "The motorised lens saved us time during installation and let us fine‑tune views without re‑mounting."
• "Integrated audio and siren proved useful for deterring intruders in a large retail car park."
• "PoE power and local microSD meant the camera kept recording during brief network outages."

The Hikvision DS-2CD2647G3-LIZS2UY/SL combines strong image quality, full‑colour night capability and practical features such as motorised varifocal optics, onboard deep‑learning analytics and built‑in audio/siren into a rugged outdoor package. For sites that need reliable 24/7 evidence‑grade colour surveillance—car parks, retail exteriors, commercial campuses and perimeter zones—this model offers a compelling balance of performance, versatility and cost effectiveness. Its PoE support, on‑board storage and industry‑standard network compatibility simplify deployment and integration with existing systems.

As with all security installations, professional installation is recommended to ensure correct positioning, power/networking and compliance with local regulations.
