Product SKU: DS-2CD20126G3-IUY-SL
Product Overview
The Hikvision DS-2CD20126G3-IUY/SL is a 12 MP Gen3 AcuSense outdoor bullet network camera designed for 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 × 2592 resolution, while the 2.8 mm fixed lens provides a wide 94.2° horizontal field of view for entrances, building perimeters and general commercial monitoring. Powered by DarkFighter low-light technology, 130 dB true WDR and up to 40 m smart IR help preserve useful detail across difficult day and night scenes. The /SL variant adds a white strobe light, audible warning, built-in microphone and speaker, allowing supported events to trigger local visual and audible deterrence. IP67 protection and NEMA 4X anti-corrosion performance further strengthen its suitability for outdoor installations.
Key Capabilities
12 MP Ultra-High-Definition Imaging
The 1/1.8-inch sensor captures up to 4608 × 2592 resolution, providing substantially more image detail than conventional 4 MP or 8 MP cameras when supported by the recorder, network and storage design.
AcuSense Human & Vehicle Classification
Deep-learning classification allows supported motion and perimeter events to focus on people and vehicles, helping reduce unnecessary alerts caused by less relevant movement within the scene.
Active Strobe Light & Audio Alarm
The /SL version 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 relying on infrared lighting.
130 dB True WDR
True 130 dB Wide Dynamic Range helps retain usable detail in scenes containing both strong backlighting and deep shadow, such as 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
- Building Entrances: Wide 2.8 mm coverage, 130 dB WDR and human/vehicle filtering suit busy entry areas with changing light.
- Perimeter Deterrence: White strobe and audible warning can provide an immediate visible and audible response to supported events.
- Commercial Properties: 12 MP resolution supports highly detailed monitoring around offices, warehouses and retail sites.
- Outdoor Installations: IP67 protection and NEMA 4X anti-corrosion performance support demanding exterior environments.
- High-Detail Evidence Capture: The 12 MP sensor is useful where image detail is prioritised over very high frame rate at maximum resolution.
Why Choose the DS-2CD20126G3-IUY/SL
The DS-2CD20126G3-IUY/SL combines very high 12 MP resolution with AcuSense classification and genuine active deterrence in a compact bullet format. Its white strobe, built-in speaker and microphone give it capabilities beyond a conventional fixed camera, while DarkFighter performance, 130 dB true WDR and 40 m IR help maintain useful imagery across difficult lighting conditions. The camera also supports local microSD storage, PoE, H.265+ compression and multiple smart-event functions. Available through Security Wholesalers, this 2.8 mm version is particularly well suited to installations needing wide coverage, fine image detail and human/vehicle-focused alerting from a single outdoor camera.
Buyer Decision Tips
Buyer Tip: At the full 4608 × 2592 resolution, the camera supports up to 20 fps. If a project prioritises smoother 25 fps recording over maximum pixel count, 3840 × 2160 or another supported lower resolution can be selected in a 50 Hz system.
Buyer Tip: The 2.8 mm lens provides a wide 94.2° horizontal field of view. Choose this version for broad area coverage; where tighter framing or greater pixel density on distant subjects is required, the compatible 4 mm or 6 mm variants 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
12 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 speaker can provide an immediate local response when supported perimeter or motion 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’s response to supported events.
- Check storage requirements if: You intend to record continuously at 12 MP, as the higher resolution can increase recorder, network and storage demand compared with lower-resolution cameras.
FAQs
- What resolution does the Hikvision DS-2CD20126G3-IUY/SL provide?
The Hikvision DS-2CD20126G3-IUY/SL captures up to 4608 × 2592 resolution from a 1/1.8-inch progressive scan CMOS sensor. At maximum 12 MP resolution it supports up to 20 fps, while 4K and lower resolutions can run at up to 25 fps in 50 Hz systems. This makes it suitable where very high image detail is required from a fixed bullet camera.
- How far can the infrared illumination reach?
The DS-2CD20126G3-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-2CD20126G3-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 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-2CD20126G3-IUY/SL support?
The camera supports AcuSense-style 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-2CD20126G3-IUY/SL be used outdoors?
Yes. The DS-2CD20126G3-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-2CD20126G3-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. It also includes a built-in microSD, microSDHC and microSDXC card slot supporting up to 512 GB of local storage, plus NAS support and Automatic Network Replenishment.
