Product SKU: DS-2CD20166G3-IUY-SL
Product Overview
The Hikvision DS-2CD20166G3-IUY/SL is a 16 MP Gen3 AcuSense outdoor bullet network camera designed for ultra-high-detail surveillance with intelligent human and vehicle classification plus active deterrence. Its 1/1.8-inch progressive scan CMOS sensor captures up to 4608 × 3456 resolution, while the 2.8 mm fixed lens provides a wide 94.5° horizontal field of view for entrances, driveways, building perimeters and general commercial monitoring. Powered by DarkFighter low-light technology, 130 dB true WDR and up to 40 m smart IR help maintain useful image detail across challenging day and night scenes. The /SL version adds a white strobe light, audible warning, built-in microphone and speaker, allowing supported events to trigger immediate local visual and audible deterrence.
Key Capabilities
16 MP Ultra-High-Definition Imaging
The 1/1.8-inch sensor captures up to 4608 × 3456 resolution, providing extremely high image detail for applications where identifying smaller scene details is more important than achieving the highest frame rate.
AcuSense Human & Vehicle Classification
Deep-learning classification allows supported motion and perimeter events to focus on people and vehicles, helping reduce nuisance alerts caused by less relevant movement within the scene.
Active Strobe Light & Audio Alarm
The /SL model combines a white strobe light with an audible warning speaker, allowing supported alarm events to trigger an immediate local deterrence response at the camera location.
DarkFighter Low-Light Performance
Powered by DarkFighter technology and a bright F1.6 aperture, the camera reaches colour illumination levels as low as 0.0008 lux before infrared illumination is required.
130 dB True WDR
True 130 dB Wide Dynamic Range helps retain useful detail in scenes containing both strong backlighting and deep shadow, including entrances, gates and loading areas.
40 m Smart Infrared
Smart 850 nm infrared illumination provides night coverage up to 40 metres and supports 0 lux operation when IR is active.
Best For
- High-Detail Commercial Surveillance: 16 MP resolution suits sites where retaining fine image detail across a wide scene is a priority.
- Building Entrances: Wide 2.8 mm coverage, 130 dB WDR and human/vehicle filtering suit entrances with changing light and frequent movement.
- Perimeter Deterrence: White strobe and audible warning can provide an immediate visible and audible response to supported events.
- Outdoor Properties: IP67 protection and NEMA 4X anti-corrosion performance support demanding exterior installations.
- Evidence-Focused Recording: The 16 MP sensor is useful where image resolution is prioritised over maximum frame rate at the highest setting.
Why Choose the DS-2CD20166G3-IUY/SL
The DS-2CD20166G3-IUY/SL combines very high 16 MP image resolution with AcuSense classification and active deterrence in a compact bullet format. Its white strobe, built-in speaker and microphone add capabilities beyond a conventional fixed camera, while DarkFighter performance, 130 dB true WDR and 40 m IR help maintain useful image detail across difficult lighting conditions. The camera also supports local microSD storage, PoE, H.265+ compression, face capture and multiple smart perimeter functions. Available through Security Wholesalers, this 2.8 mm version is particularly well suited to wide-area installations where image detail, human and vehicle filtering and local deterrence are all important.
Buyer Decision Tips
Buyer Tip: At the full 4608 × 3456 resolution, the camera supports up to 12.5 fps in a 50 Hz system. If smoother motion is more important than maximum pixel count, 4608 × 2592 supports up to 20 fps and 4K or lower resolutions support up to 25 fps.
Buyer Tip: The 2.8 mm lens provides a wide 94.5° horizontal field of view. Choose this version for broad scene coverage; where tighter framing or greater pixel density on distant subjects is required, the compatible 4 mm or 6 mm versions may be more suitable.

Ideal Use Cases
Building Entrances
The wide 2.8 mm field of view, 130 dB WDR and human/vehicle filtering suit entrances with strong backlighting and frequent movement.
Warehouse Perimeters
16 MP detail, 40 m IR and active deterrence make the camera useful around external walls, loading areas and access routes.
Retail & Commercial Sites
High resolution and AcuSense classification provide detailed monitoring while reducing alerts from non-human and non-vehicle movement.
Active Deterrence Zones
The white strobe and built-in speaker can provide an immediate local response when supported motion or perimeter events are triggered.
Moderately Corrosive Environments
NEMA 4X protection and Hikvision’s moderate anti-corrosion classification suit supported sites with higher corrosion demands than standard installations.
Choosing the Right Model
- Choose the 2.8 mm version if: You need broad coverage over entrances, driveways, yards or general surveillance areas.
- Consider the 4 mm or 6 mm versions if: The priority is tighter framing and greater pixel density on subjects farther from the camera.
- Choose the /SL model if: White strobe deterrence and audible warning are required as part of the camera response to supported events.
- Check recorder and storage requirements if: You intend to record continuously at 16 MP, as maximum-resolution recording requires substantially more storage than lower-resolution configurations and operates at a lower frame rate.
FAQs
- What resolution does the Hikvision DS-2CD20166G3-IUY/SL provide?
The Hikvision DS-2CD20166G3-IUY/SL captures up to 4608 × 3456 resolution from a 1/1.8-inch progressive scan CMOS sensor. At maximum 16 MP resolution it supports up to 12.5 fps in 50 Hz systems, while 4608 × 2592 supports up to 20 fps and 4K or lower resolutions can run at up to 25 fps. This makes it suitable where very high image detail is more important than maximum frame rate.
- How far can the infrared illumination reach?
The DS-2CD20166G3-IUY/SL provides smart infrared illumination up to 40 metres using 850 nm IR. The camera can operate at 0 lux with IR active, while its DarkFighter low-light performance reaches 0.0008 lux in colour at F1.6 before infrared is needed. This combination supports detailed day and night surveillance across typical commercial and perimeter scenes.
- Does the DS-2CD20166G3-IUY/SL include active deterrence?
Yes. The /SL model includes a white strobe light and audible warning for active deterrence. It also has a built-in speaker rated up to 110 dB at 10 cm and a built-in single microphone, allowing local audio capture and alarm warning functions. These features can be linked to supported events to help draw attention to detected activity.
- What AcuSense functions does the DS-2CD20166G3-IUY/SL support?
The camera supports human and vehicle classification based on deep learning. Perimeter protection functions include line crossing, intrusion, region entrance and region exiting, with alarms able to trigger by specified target types such as people or vehicles. It also supports motion detection with human and vehicle filtering, scene change detection and face capture.
- Can the DS-2CD20166G3-IUY/SL be used outdoors?
Yes. The DS-2CD20166G3-IUY/SL is rated IP67 for water and dust resistance and is specified for operation from -30°C to 60°C. Hikvision also lists NEMA 4X anti-corrosion protection with a moderate protection classification. For Security Wholesalers installations, the mounting location, cable entry and network or power method should still be selected to suit the actual site conditions.
- What power and storage options does the DS-2CD20166G3-IUY/SL support?
The camera can be powered by 12 VDC or PoE using IEEE 802.3at Class 4. Maximum power consumption is 15.6 W on 12 VDC and 19 W on PoE.
