Detailed specifications and benefits
The DS-2CD2047G2H-LIU uses a 1/1.8" progressive-scan CMOS sensor and delivers a maximum image resolution of 2688 × 1520 (4 MP). The combination of a large sensor and an F1.0 fixed 4 mm lens increases light-gathering capability, which translates to better detail and lower noise in dim scenes. Image enhancement features such as BLC, HLC, 3D DNR and Defog help maintain clarity in challenging lighting and weather conditions. With a quoted signal-to-noise ratio ≥ 52 dB and 130 dB WDR, this camera is well-suited to scenes with high contrast lighting.
ColorVu technology allows the camera to retain colour information down to 0.0005 Lux (with AGC on), and the Smart Hybrid Light system pairs IR and white light to provide full-colour images even at 0 Lux when white light is triggered. The supplement light range of up to 40 m makes it capable of illuminating larger driveways, yards and entryways while the 850 nm IR ensures passive night visibility if white light is not desired.
The camera supports H.265/H.264 codecs (plus their streamlined variants H.265+ and H.264+) and offers MJPEG on the sub-stream. It can output up to 25/30 fps at full 4 MP resolution (region dependent) and supports multiple streams (main, sub, third) with up to six simultaneous live viewers. Bitrate control from 32 Kbps to 8 Mbps combined with efficient compression reduces storage and network load while preserving image quality where it matters.
Built-in deep-learning analytics allow human/vehicle classification, reducing false alarms caused by moving foliage or small animals. Perimeter protection rules such as line crossing and intrusion detection provide actionable alerts for security operators. Active deterrence tools include a built-in strobe and an audible alarm, plus two-way audio through the on-board microphone and speaker (speaker output ≈ 1.2 W, with common audio codecs supported). These features let you detect, verify and deter incidents proactively.
The DS-2CD2047G2H-LIU connects via a standard RJ45 10/100 Mbps Ethernet port and supports common protocols including TCP/IP, HTTPS, RTSP and ONVIF (Profile S/T), enabling integration with third-party VMS and NVRs. Local storage is supported via microSD/microSDHC/microSDXC (up to 512 GB), while NAS (NFS, SMB/CIFS) and ANR provide redundancy in case of network interruptions. Power options include 12 VDC (0.54 A, max 6.5 W) or PoE (IEEE 802.3af, Class 3, max 8 W) for flexible installations.
Built in a metal housing (Ø 74.4 mm × 179.2 mm, ≈ 510 g), the camera is designed for outdoor use with an operating temperature range of -30 °C to 60 °C and an IP67 ingress protection rating. This rugged build ensures long-term reliability in exposed locations, from cold winters to hot summers.
Certifications include UL 62368-1, CE-LVD, CE-EMC and RoHS. Warranty and support terms depend on the supplier and purchase channel; confirm warranty coverage with your reseller or installer. Professional installation is recommended to meet local wiring, mounting and safety regulations.
Use cases and scenarios where the camera excels
The DS-2CD2047G2H-LIU is tailored to applications that require reliable colour imaging at night, proactive deterrence and accurate object classification. Examples include:
- Residential perimeter and driveway monitoring:Capture licence plates, faces and clothing colours at night without relying solely on monochrome IR footage. The hybrid light can be set to trigger only when needed to reduce unwanted illumination.
- Retail entrance and storefront surveillance:Use human/vehicle classification to reduce false alarms, and the two-way audio to communicate with visitors or deter suspicious behaviour.
- Commercial properties and parking areas:Benefit from 4 MP detail and long-range supplemental lighting to monitor larger areas such as parking lots, loading bays and perimeters.
- Education and public spaces:Deep-learning analytics and perimeter rules help security teams focus on real threats rather than nuisance detections.
- Small business and branch offices:PoE compatibility simplifies deployment where access to power is limited and microSD/NAS support provides flexible recording choices.
Comparisons with similar products on the market
When evaluating the DS-2CD2047G2H-LIU, it helps to compare it across several dimensions: night-time colour performance, analytics, build quality and cost of ownership.
- Color vs IR-only cameras:Traditional IR cameras switch to monochrome at night and rely on IR reflectivity, which loses colour information. The ColorVu hybrid approach keeps colour detail in low light and uses white light on demand for 0 Lux colour images — a major advantage for forensic clarity.
- Against other ColorVu / hybrid-light models:Many manufacturers offer similar hybrid-light products; the DS-2CD2047G2H-LIU stands out with a large F1.0 aperture and 4 MP resolution, striking a balance between sensitivity and detail. If you need wider area coverage or longer focal lengths, other SKUs in the same product family may offer different lenses (e.g., 2.8 mm, 6 mm).
- Analytics and smart features:The inclusion of on-board deep-learning human/vehicle classification and perimeter protection is comparable to offerings from other mainstream vendors. The benefit here is reduced false positives and greater actionable alerts without relying entirely on backend analytics.
- Price and total cost:With a suggested retail price around 149.00 (check current supplier pricing), this camera typically offers a cost-effective mix of night-time colour capability, analytics and PoE convenience compared with higher-end multi-sensor or PTZ solutions. For budget-conscious projects, 2 MP ColorVu units may be less expensive but at a trade-off in resolution.
Representative customer feedback and reviews
Below are concise, anonymised examples of the kind of feedback installers and end users commonly report when using the DS-2CD2047G2H-LIU. These are representative summaries rather than direct quotes from named individuals.
- Installer perspective:"Easy PoE installation, solid metal build and reliable outdoors. Customers appreciate the colour night images — makes identifying vehicles and clothing much easier than IR-only cams."
- Business owner:"Improved deterrence after we enabled the strobe and audio alarm. Few false alarms thanks to the human/vehicle classification — our security team spends less time reviewing alerts."
- Homeowner:"Clear pictures of the driveway at night. The camera handled winter temperatures without issues and we liked having local microSD backup in case the network drops."
As with any security product, results depend on placement, lighting setup and configuration. Professional tuning of motion/analytics thresholds and positioning will maximise performance and minimise false positives.
Conclusion — why this camera is a great choice
