The Hikvision DS-2CD2166G2H-ISU is a 6 MP fixed-dome network camera with DarkFighter low-light technology, built-in microphone (SU version), deep-learning human/vehicle classification, and optional lens configurations (2.8 mm, 4 mm) including a black-finish 2.8 mm variant — ideal for versatile installations in both indoor and outdoor environments.
The Hikvision DS-2CD2166G2H-ISU combines advanced imaging, smart analytics, and ruggedised design in a single unit. With a 1/2.4″ progressive-scan CMOS sensor capturing up to 3200 × 1800 resolution (6 MP), it ensures detailed images suitable for recognition and analysis. It features DarkFighter technology for exceptional performance in extremely low-light conditions (colour at 0.001 lux) and 120 dB true WDR for handling strong backlight or high-contrast scenes.
Lens options: choose between a wide-angle 2.8 mm lens (horizontal field ~114.8°) and a tighter 4 mm lens (horizontal ~94°) depending on coverage needs. A black finish variant in 2.8 mm is also available for more discreet aesthetic applications. The cameras are built for outdoor/harsh installation: IP67 rated for dust/water ingress and IK10 vandal-resistant.
On the analytics side, it includes built-in deep-learning classification of humans and vehicles, supported by smart IR (up to 30 m range), on-board audio via built-in microphone, H.265+/H.265/H.264+ compression for efficient bandwidth/storage use, and an array of network/security features (ONVIF, TLS/HTTPS, 802.1x, etc.). The flexible lens and variant options make it well suited for retail, commercial, campus, car-park, or city-infrastructure projects.

Traveller’s Installer Tips
Choose the lens variant depending on your field of view requirement: 2.8 mm for wide coverage (e.g., lobby areas, retail floor), 4 mm for narrower or more focused coverage (e.g., drive-way, corridor).
If aesthetic matters (e.g., hotel facade, dark ceiling) consider the black 2.8 mm variant for less visual impact.
Ensure appropriate height/angle to exploit the wide field of the 2.8 mm lens without distortion near edges.
Use PoE where possible for simpler wiring; verify your switch supports IEEE 802.3af Class 3.
For outdoor installation: ensure mount and junction box allow weather-sealing (IP67) and protect from direct sunlight or reflection that can interfere with low-light performance.
Use the built-in microphone (SU version) if audio capture is required — confirm compliance with local audio recording laws.
Configure the smart audio/video analytics (human/vehicle) to reduce false alarms in high traffic areas.
When installing IR zone: ensure no reflective surfaces in front of the camera lens that might bounce IR back and reduce image clarity.
Label model variant clearly (lens and colour) on installation documents for future service or expansion.
Maintain firmware updates for analytics and security enhancements.
Frequently Asked Questions (FAQs)
Q: What lens sizes are available for this model? A: It’s available in fixed 2.8 mm and 4 mm lenses. A black 2.8 mm variant is also offered for less conspicuous mounting.
Q: Does this camera perform well in very low light? A: Yes. It uses DarkFighter technology and supports colour imaging down to 0.001 lux, plus IR to ensure performance at night.
Q: Is the camera suitable for outdoor or harsh environments? A: Yes. It is rated IP67 for dust/water resistance and IK10 for vandal protection.
Q: What is DORI (Detect/Observe/Recognise/Identify) distance for each lens? A: For 2.8 mm: Detect ~64 m, Observe ~25 m, Recognise ~12 m, Identify ~6 m. For 4 mm: Detect ~77 m, Observe ~30 m, Recognise ~15 m, Identify ~7 m.
Q: Can I use this with my existing network and VMS? A: Yes. It supports standard protocols (ONVIF Profile S/G/T), H.265+/H.264, and can be integrated into most professional VMS platforms.
Q: What power options are there? A: You can power it via 12 V DC input or PoE (IEEE 802.3af Class 3) which simplifies wiring.
Q: Does it include audio? A: The “SU” variant includes a built-in microphone. Other variants may not have audio capability.
Q: Can I mount it on walls or ceilings? A: Yes. The dome form allows flexible mounting (ceiling or wall) with 3-axis adjustment (pan, tilt, rotate) for correct orientation.
