Introduction: Meet the DS-2CD2387G2H-LISU/SL 8MP ColourVu PoE Turret
The DS-2CD2387G2H-LISU/SL is an 8 MP (4K) ColourVu fixed‑turret network camera designed for situations where clear, actionable colour imaging and active deterrence are required around the clock. Combining full‑time colour capture, Smart Hybrid Light (white light + IR), deep‑learning analytics and onboard active deterrence (strobe + speaker), this turret camera is positioned as an all‑in‑one IP CCTV solution for residential and commercial perimeter surveillance, retail spaces, parking areas and contractor installations.
Key highlights: 8 MP (3840 × 2160) resolution, full‑time ColourVu for vivid colour in low light, Smart Hybrid Light up to 30 m, built‑in microphone and speaker with audio alarm, human/vehicle classification and perimeter analytics, plus PoE (IEEE 802.3af) or 12 VDC power and IP67 weatherproofing.
Detailed specifications and benefits
At the heart of the DS-2CD2387G2H is a 1/1.8" progressive scan CMOS sensor delivering up to 8 MP resolution (3840 × 2160). Fixed lens options (2.8 mm or 4 mm, F1.0) let you choose a wider field of view (H 108.8° for 2.8 mm) or a slightly narrower, more focused scene (H 93.3° for 4 mm). The large aperture (F1.0) and ColourVu technology enable very low‑light colour imaging—minimum illumination is as low as 0.0008 Lux with AGC enabled, and the camera can capture full‑colour images even when ambient light is minimal.
The camera combines white light and IR in a Smart Hybrid Light system. White strobe illumination provides colour images and acts as a visual deterrent, while IR extends detection capability in truly dark scenes. Supplement light can reach up to 30 m, and the IR uses an 850 nm wavelength. This hybrid approach gives clear identification options at night—footage with colour is typically more useful for recognition than monochrome IR images.
The DS-2CD2387G2H supports 130 dB WDR and multi‑mode noise reduction (3D DNR, BLC/HLC, defog), which helps preserve detail in high‑contrast scenes (for example, a bright sky and dark ground). Modern codecs are supported (H.265 / H.264 variants including optimized + versions) to reduce bandwidth and storage needs without sacrificing image fidelity. The camera can output main, sub and third streams for flexible recording and remote viewing.
One of the major differentiators is the built‑in deep‑learning analytics: human/vehicle classification, face capture and perimeter protection functions (line crossing, intrusion, region entry/exit). These capabilities reduce false alarms and allow more intelligent event triggers. When an incident is detected the camera can trigger active deterrence: a white strobe light and configurable audio alarm/siren via the built‑in speaker. Combined, these features both notify operators and can discourage unwanted behaviour in real time.
Audio is supported with a built‑in microphone and mono speaker. Multiple audio codecs are available (G.711, G.722.1, G.726, MP3, AAC‑LC) for compatibility with different recording systems. Local storage via microSD/microSDHC/microSDXC supports cards up to 512 GB; network storage (NFS/SMB/CIFS) and ANR are supported for redundancy during network interruptions. For power and data the camera accepts PoE (IEEE 802.3af, Class 3) or 12 VDC ±25%, with power consumption roughly 10.5 W (PoE) or 9 W (12 VDC).
The turret is IP67 rated for outdoor use and runs across a wide operating temperature range (−30 °C to 60 °C), making it suitable for exposed sites in varied climates. Physical dimensions are compact (Ø138.3 mm × 115.4 mm) and it weighs approximately 820 g, keeping installation straightforward for wall or ceiling mounting.
Use cases and scenarios where this camera excels
- Perimeter and property protection:For homes, schools, offices and industrial sites that require 24/7 colour identification and a visible deterrent, the ColourVu and strobe/siren combination provides both evidence capture and a response mechanism to intrusions.
- Retail and loss prevention:Retail environments benefit from high‑resolution colour images to identify people, clothing and vehicle details. Deep‑learning classification helps reduce false alarms from foliage or animals and focuses alerts on human or vehicle events.
- Car parks and driveways:The 4K resolution captures licence plates, vehicle makes and colours at a distance, while active deterrence and face capture add further investigative value.
- Construction and contractor sites:Outdoor, temporary or semi‑permanent sites need rugged cameras with flexible power options—PoE simplifies deployment and ColourVu improves incident capture after dark.
- Small campuses and multi‑site deployments:Built‑in analytics reduce dependency on constant operator monitoring and help scale surveillance with automated alarms routed to an NVR or cloud service.
How it compares with similar cameras on the market
Compared to legacy IR‑only cameras, the DS-2CD2387G2H stands out for its full‑time colour capability and Smart Hybrid Light. IR‑only models deliver good night contrast but lose colour information that can be crucial for identification; ColourVu keeps colour fidelity in low light and the strobe adds a deterrent function many IR cameras lack.
Against other 4K PoE turret cameras, this model competes on three fronts: sensor/aperture performance (1/1.8" with F1.0), onboard analytics (deep‑learning human/vehicle classification and face capture) and active deterrence (speaker + strobe). Some competing cameras may match 4K resolution but lack the hybrid lighting system or advanced analytics, making the DS-2CD2387G2H a stronger option where night‑time identification and false‑alarm reduction are priorities.
Compared with dome form factors, turret cameras can be easier to position for angled views and often provide equivalent image quality with simpler mounting. Dome cameras may appeal when tamper protection and a lower profile are required, while turret cameras like this model balance visibility (helpful for deterrence) and performance.
What customers and installers typically say
Publicly available feedback for cameras with similar feature sets generally praises the combination of 4K resolution and full‑colour nighttime imaging for improving identification and evidence value. Installers often highlight PoE support as a major convenience—one cable for power and data—plus the usefulness of onboard storage for redundancy.
Common installer notes include: ensure proper PoE switch provisioning (IEEE 802.3af, Class 3) and that mounting sites consider the camera’s field of view (2.8 mm vs 4 mm) relative to the area being covered. For permanent mains work or certain outdoor junctions, many installers remind customers to follow local electrical regulations and use qualified electricians for fixed power connections.
Where users offer constructive criticism, it typically relates to fine‑tuning analytics for a particular environment (for example, adjusting detection zones to lower false triggers from nearby roads or foliage) and ensuring firmware updates are applied for the best performance and security.
Conclusion: Why the DS-2CD2387G2H-LISU/SL is a strong choice
For buyers seeking a compact, rugged 4K turret camera that prioritises night‑time identification and active deterrence, the DS-2CD2387G2H-LISU/SL is a compelling option. It blends high‑resolution imaging with ColourVu and Smart Hybrid Light, advanced deep‑learning analytics to cut false alarms and provide meaningful alerts, and practical deployment features like PoE and microSD storage. The addition of a built‑in speaker and strobe light means the camera can actively respond to events rather than simply recording them—useful in retail, parking or perimeter security scenarios.
At a suggested price point of approximately 209 (price may vary by region and reseller), this camera targets users who need more than a basic camera: a single‑device solution for detection, identification and deterrence. Before purchase and installation, consult the manufacturer datasheet and quick start guide for up‑to‑date firmware, mounting instructions and compliance details (CE/UKCA) and, if necessary, engage a qualified installer to meet local electrical and building regulations.
In short: the DS-2CD2387G2H-LISU/SL delivers excellent night‑time colour performance, practical analytics and active deterrence in a weatherproof turret package—making it a versatile choice for many modern surveillance needs.
