Hikvision DS-2CD2647G2T-LZS 4MP ColorVu Bullet Camera

Hikvision DS-2CD2647G2T-LZS 4MP ColorVu Bullet Camera

The DS-2CD2647G2T-LZS is a 4MP outdoor bullet camera purpose-built for color surveillance in near-total darkness—a capability that separates it from traditional infrared designs. At 0.0005 Lux with F1.0 aperture, this camera captures usable color detail in lighting conditions where IR cameras default to grayscale. The integrated white light supplementation extends to 60 meters, making it practical for large perimeter areas without requiring separate floodlights.

Key Features

• ColorVu Technology (0.0005 Lux): Records true color at minimal illumination—critical when facial recognition, vehicle plate capture, or clothing detail matters. IR-only cameras lose this color data permanently, forcing forensic teams to work with contrast-only images.
• 1/1.8" Progressive Scan CMOS Sensor: Larger sensor footprint than typical 1/2.8" designs means each pixel captures more light. Translates to cleaner images in dusk and pre-dawn hours without cranking gain to the point of noise.
• Motorized Varifocal Lens (2.8–12mm, F1.0): F1.0 maximum aperture is exceptionally bright—more light reaches the sensor than typical F2.0 designs. The varifocal range (105.4° to 56.4° horizontal FOV) lets you dial in coverage at installation without swapping lenses. DORI specifications: detection at 66.8–110.4m, recognition at 13.4–22.1m, identification at 6.7–11m depending on focal length chosen.
• 130dB Wide Dynamic Range (WDR): Simultaneous backlighting and shadow detail—necessary when the camera views bright parking lot entrances against dark building returns or glare from vehicle headlights.
• H.265 and H.264 Encoding (up to 30fps full 4MP): H.265 cuts bandwidth and storage footprint nearly in half versus H.264 at equivalent quality, a tangible cost reduction across 24/7 multi-camera deployments. Sub-stream and optional third-stream options allow simultaneous transmission at different resolutions—critical for mobile remote viewing over constrained networks.
• AI-Powered Detection (Motion, Line Crossing, Intrusion, Face Capture): On-camera deep learning filters noise and false alarms. Line crossing and region intrusion detection reduce alert storms from blown leaves or passing vehicles; face capture feeds automated identification workflows.
• IP67/IK10 Rating: Dust-tight and fully submersible to 1 meter for 30 minutes—handles rain, snow, washdown spray. IK10 rating withstands 20J impacts, relevant for high-traffic outdoor sites.
• PoE Powered (Max 18W, 802.3at): Operates on standard 95-watt switch ports without straining power budgets. No separate 12V power supply lines to run, simplifying both installation and future expansions.
• microSD/microSDHC/microSDXC Storage (up to 512GB): ANR (Automatic Network Replenishment) on the card continues recording if network connectivity drops, then syncs footage once reconnected. Onboard storage acts as a hedge against NVR buffer loss.
• Ethernet Connectivity (10/100M RJ-45): Standard single-cable PoE deployment. HTTPS, 802.1X, watermarking, and IP filtering lock down access. Supports 32 concurrent users across three privilege levels.

Integration and Compatibility

The DS-2CD2647G2T-LZS integrates with Hikvision IP cameras via ONVIF standards, iVMS-4200 client software, Hik-Connect cloud, and Hik-Central management platforms. Pair with network video recorders running H.265 decoding to maximize storage efficiency across multi-camera systems. Standard PoE power planning applies—confirm switch availability before ordering multiple units.

When to Choose a Different Model

If your lighting conditions allow standard daylight operation and color at night is not a priority, a lower-cost 4MP outdoor bullet without ColorVu will suffice. If you need 8MP or higher resolution for distant identification or crowd counting, consider a higher-megapixel variant in the same outdoor IP camera family. If the deployment is purely indoors with stable lighting, an indoor turret or compact bullet will be more cost-effective.

Frequently Asked Questions

Q: Does the DS-2CD2647G2T-LZS require separate white light floodlights?

A: The built-in white light supplement covers up to 60 meters, reducing or eliminating the need for external lighting in most outdoor scenarios. Extremely large open areas (parking lots over 200 feet) may still benefit from perimeter floods for uniform illumination.

Q: What is the difference between ColorVu and traditional IR night vision?

A: ColorVu records true color at minimal ambient light; IR records only grayscale. For facial recognition, vehicle registration plates, and clothing description, color is irreplaceable. IR excels in total darkness but trades color for range.

Q: Can I adjust the white light brightness, or does it activate automatically?

A: The white light features smart supplement activation—it intelligently turns on based on ambient light levels rather than running continuously. You can configure activation thresholds and intensity levels within the camera's settings.

Q: What NVR or storage system works with the DS-2CD2647G2T-LZS?

A: Any ONVIF-compliant NVR or recorder supports this camera. Hikvision NVRs (DS-7600 series and above) are optimized for it, but third-party platforms from other vendors will work if they decode H.265.

Q: Is the lens interchangeable, or is it fixed to the camera body?

A: The motorized varifocal lens (2.8–12mm) is factory-mounted and motorized, not user-swappable in the field. You adjust focal length via the NVR or client software during commissioning.

Q: How much storage does 24/7 recording consume on the microSD card?

A: At 4MP with H.265 encoding and standard bit rates (2–4 Mbps), a 512GB card typically stores 7–14 days of continuous footage, depending on scene complexity and motion. H.264 reduces this to 4–7 days at equivalent quality.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The DS-2CD2647G2T-LZS (often searched as DS 2CD2647G2T LZS) fills a real gap in outdoor surveillance: effective nighttime identification without sacrificing color. The 0.0005 Lux specification with F1.0 aperture is the operative metric here—it's not marketing fluff. Most 4MP bullets sit at 0.01–0.03 Lux, meaning they require 20–60 times more ambient light or force you into grayscale IR territory. At twilight, during overnight incidents, or in low-ambient urban settings (parking garage exits, back-alley perimeters), this camera keeps color detail while competitors default to monochrome.

Technical Highlights:

• 1/1.8" CMOS and F1.0 Aperture: Pixel size and light transmission compound—this sensor collects roughly 2.5 times more photons per unit area than a typical 1/2.8" F2.0 design at equivalent megapixel count. In practice: cleaner, less-noisy 11 PM footage without cranking ISO to useless levels.
• H.265 Encoding at Full 4MP 30fps: Storage and bandwidth math: H.265 yields 40–60% file size reduction versus H.264 at equivalent quality. Over 12 months on a single camera, that's 2–3 TB of saved storage. Across a 16-camera deployment, you're looking at 32–48 TB reduction—a material capex difference.
• AI Face Capture and Line Crossing Detection: On-camera processing means fewer false-alarm notifications and smarter forensic indexing. The face capture output feeds directly into identification workflows without requiring a separate analytics server license.
• 60m White Light Supplementation: Eliminates the false binary between IR (poor color) and external floods (wiring, maintenance, power draw). 60 meters covers most parking lots and perimeters without additional infrastructure.

Deployment Considerations:

• Lens Commissioning Requires NVR or Client Access: The 2.8–12mm motorized lens is adjusted remotely, not via an onboard dial. You must have the NVR or iVMS-4200 client running to zoom to the correct focal length at installation. Budget 30 minutes for initial focus tuning.
• PoE Power Budget Watch: At 18W max draw, this camera is friendly to standard 802.3at switches, but daisy-chaining multiple ColorVu models on a single 95W switch requires arithmetic. Four cameras = 72W; five cameras risk overcurrent lockout. Verify switch capacity before expanding.
• Storage Calculation Baseline: At H.265 and 4MP with typical motion-weighted bit rates (2–3 Mbps), expect roughly 10 days of 24/7 recording on a 512GB microSD card. If retention policy mandates 30 days, plan for dual-card redundancy or mandatory NVR recording in parallel.

Deploy the DS-2CD2647G2T-LZS for perimeter-security scenarios where dusk-to-dawn color identification and facial recognition are operational priorities: parking-lot access control, warehouse loading-dock surveillance, or facility entrances where lighting is minimal and cost per incident is high. It's not a universal outdoor bullet, but for the specific use case—color imaging in near-darkness without IR—it's the right engineering choice.
