DS-2CD2147G3-LIS2UY 4 MP ColorVu Hybrid-Light Dome Camera (4 mm)

DS-2CD2147G3-LIS2UY 4 MP ColorVu Hybrid-Light Dome Camera — Introduction and Key Features

The DS-2CD2147G3-LIS2UY is a fixed 4 MP network dome camera from Hikvision designed for demanding outdoor surveillance where colour detail and active deterrence matter. Branded with Hikvisions ColorVu technology and a Hybrid Smart Light (white light + IR), this dome delivers full-colour imaging in very low light and switches to IR when needed for seamless 24/7 coverage. The S2U variant adds dual array microphones, an on-board speaker/siren and active visual alerts to support live-guard and active deterrence workflows. Ruggedised with IP67, IK10 and NEMA 4X ratings, the camera is built to withstand harsh outdoor environments.

• Colour at night:ColorVu F1.0 optics and hybrid lighting produce detailed colour images in low-light conditions that normally require IR-only imaging.
• Active deterrence:Speaker/siren and white light flashes (S2U variant) enable audible/visual warnings to deter intruders in real time.
• Smart analytics:Deep-learning based person/vehicle classification, face capture and perimeter protection reduce false alarms and improve detection accuracy.
• Flexible deployment:PoE or 12 VDC power options, on-board microSD storage up to 512 GB and broad protocol support (ONVIF S/G/T, HTTPS, 802.1X) simplify integration.
• Rugged construction:IP67, IK10 and NEMA 4X make it suitable for exposed outdoor installations.

• Superior low-light colour:The F1.0 aperture and ColorVu processing let the camera gather much more light than typical lenses, producing recognisable colour images at ambient illuminations where other cameras would switch to monochrome IR. This is critical when colour is needed for evidence: clothing, vehicle colours, signage and license plate background details.
• Hybrid lighting for versatility:Combining white LEDs and IR extends the cameras usefulness across lighting conditions. White light can be used for detailed colour capture and deterrence, while IR preserves covert observation when required.
• Accurate detections, fewer false alarms:Deep-learning analytics distinguish people and vehicles more effectively than motion-only triggers. This reduces time wasted on irrelevant alerts and improves situational awareness.
• Secure network integration:Support for ONVIF and secure protocols (HTTPS, 802.1X) makes integration with VMS and enterprise networks straightforward while supporting modern security best practices.
• Rugged, low-maintenance design:IP67, IK10 and NEMA 4X ratings mean resistance to water ingress, impacts and corrosion  ideal for coastal, industrial or exposed public settings.

Use Cases and Scenarios Where the Camera Excels

The DS-2CD2147G3-LIS2UY is particularly valuable where both recognisable colour imagery and active deterrence are required. Typical use cases include:

• Retail and commercial entrances:Capture clear, colour images of faces and clothing at night for loss prevention and incident investigation. The active speaker/siren can warn intruders or unwanted behaviour in near-real time.
• Perimeter security for offices and warehouses:Use person/vehicle classification and perimeter protection rules (line crossing, intrusion) to focus attention on real security events and trigger active deterrence lighting if needed.
• Parking lots and access roads:Colour capture at low light aids in identifying vehicle colours and other details; the wide horizontal field of view from the 4 mm lens covers broader areas with fewer cameras.
• Critical infrastructure and utilities:Rugged construction and corrosion resistance (NEMA 4X) suit harsh environments while intelligent analytics provide reliable alarm inputs for SOC workflows.
• Schools and campuses:Two-way audio and visible warnings help manage behaviour and allow security staff to interact remotely when required.

How It Compares to Similar Products

Comparing the DS-2CD2147G3-LIS2UY with other cameras helps highlight where it adds the most value.

• Standard IR domes typically switch to monochrome imaging in low light and rely solely on IR illumination, losing colour detail. The ColorVu hybrid approach preserves colour, improving identification and situational context.
• Hybrid white light also enables active deterrence visual cues, which IR-only cameras cant provide.

• 4 MP resolution yields higher detail for distant subjects and allows more effective digital cropping without losing recognisability. This is particularly useful for identifying faces and vehicle details from moderate distances.
• Higher resolution combined with ColorVu means both more pixels and better low-light quality, giving a notable edge in evidentiary scenarios.

• Many manufacturers now offer low-light colour solutions; differences come down to aperture, sensor size, image processing and hybrid lighting implementation. The DS-2CD2147G3-LIS2UYs 1/1.8" sensor, F1.0 aperture and hybrid light with active deterrence features place it competitively among mid-range to premium outdoor dome cameras.
• Integration maturity (ONVIF support, H.265 efficiency, WDR 130 dB) and rugged ratings (IP67/IK10/NEMA 4X) make it a robust choice when environmental resilience and analytics are needed together.

Customer Testimonials and Installer Feedback

Official customer reviews for specific SKUs like the DS-2CD2147G3-LIS2UY vary by market and reseller. If vendor-supplied testimonials are not available, common feedback themes from installers and security teams using Hikvision ColorVu hybrid cameras include:

• "Noticeably improved night-time footage: teams often report that colour details captured at dusk or in street-lit areas are far more useful than IR-only recordings."
• "Reduced false alarms and better detection: deep-learning analytics cut down time spent reviewing motion-only alerts and increase the proportion of meaningful notifications."
• "Simpler deployments: PoE power and ONVIF compatibility speed up integration with existing VMS solutions, and on-board microSD gives a reliable local backup option."
• "Active deterrence works: projects that tested the flashing white light and audio warnings reported fewer repeat incursions in pilot zones."

For purchase decisions, request reference installations or demo footage from your reseller to confirm performance in environments similar to your site.
