Product Overview
Built for commercial and institutional sites where coverage framing, low-light performance, and rugged durability must work together, the DS-2CD3787G3T-LIZSU(Y) is an 8MP Ultra Series dome camera from Hikvision that brings genuine installation flexibility to demanding outdoor and semi-outdoor environments. Featuring a motorised varifocal 2.7-13.5mm lens at F1.2, the field of view can be adjusted remotely from approximately 112 degrees at the wide end down to 41 degrees for focused distance coverage, without repositioning the camera. Equipped with DarkFighter 2.0 and Smart Hybrid Light combining IR and white-light illumination up to 40m, this model maintains detailed colour imaging across changing light conditions. Incorporating an HEOP AI platform, it classifies human and vehicle targets to support more accurate event triggers. The housing carries IP67 weather protection, IK10 vandal resistance, and the -Y anti-corrosion coating for exposed coastal or industrial installations.
Key Capabilities
8MP 4K Resolution
The 3840 x 2160 pixel output from a 1/1.8-inch progressive-scan CMOS sensor captures wide scene detail that holds up under digital zoom during review. This matters for identifying individuals or vehicles across large building frontages, car parks, or campus zones where a fixed-lens camera would require multiple units to match the coverage area.
Motorised Varifocal 2.7-13.5mm Lens
The F1.2 motorised lens allows remote zoom and focus adjustment from wide-area coverage at approximately 112 degrees down to a focused 41-degree view for corridors or entry points. Installers can frame coverage during commissioning or adjust the scene remotely as site requirements change, without physical access to the camera head.
DarkFighter 2.0 Low-Light Imaging
DarkFighter 2.0 improves colour retention and contrast in scenes with minimal ambient lighting, reducing the dependence on supplemental white light for night-time identification. For sites such as transport hubs or educational campuses where lighting levels vary significantly after hours, this translates to more usable footage across a wider range of conditions.
Smart Hybrid Light up to 40m
The integrated IR and white-light LEDs operate as a combined Smart Hybrid Light system, automatically adapting illumination mode to the scene. This allows the camera to deliver full-colour footage when white light is appropriate and switch to discreet IR when colour illumination is not required, across a range of up to 40m from the camera position.
HEOP AI Platform with Human and Vehicle Classification
The onboard HEOP AI-ISP compute platform processes human and vehicle targets directly on the camera, filtering out irrelevant motion triggers from environmental sources. For security teams monitoring high-traffic commercial or institutional sites, this classification layer reduces the volume of non-event alerts reaching the operator and improves response accuracy.
IP67, IK10, and -Y Anti-Corrosion Protection
Full IP67 weatherproofing and IK10 vandal resistance make this dome camera suitable for exposed outdoor mounting points. The -Y variant adds a NEMA 4X-rated anti-corrosion coating across the housing, making it directly appropriate for coastal environments, chemical processing areas, or industrial yards where standard camera housings would degrade over time.
Best For
- Adjustable Coverage Sites: The motorised 2.7-13.5mm varifocal lens makes this camera well suited to installations where the exact field of view needs to be confirmed during commissioning or adjusted post-installation without physical camera access.
- Low-Light Commercial Environments: DarkFighter 2.0 combined with Smart Hybrid Light up to 40m supports sites such as transport terminals, educational campuses, and retail precincts where lighting conditions shift significantly through the night.
- Vandal-Prone or Exposed Outdoor Mounting: IK10 impact resistance and IP67 weatherproofing support ceiling and overhead wall mounting in car parks, building perimeters, and public-access areas where physical tampering or harsh weather is a factor.
- Coastal or Industrial Deployments: The -Y anti-corrosion housing variant is specifically intended for sites near salt air, industrial processing zones, or other corrosive atmospheres where standard camera housings have a shortened service life.
- AI-Assisted Monitoring: The HEOP AI platform with human and vehicle classification suits control room operators and monitoring services where reducing nuisance alerts from non-human triggers is a practical operational requirement.
Why Choose the DS-2CD3787G3T-LIZSU(Y)
The DS-2CD3787G3T-LIZSU(Y) occupies a well-defined position among professional-grade dome cameras for sites that need more than fixed-lens 8MP coverage. The motorised varifocal lens removes the framing guesswork from dome installations on large building facades or campus environments, allowing precise scene adjustment after mounting. DarkFighter 2.0 goes further than standard low-light sensors by preserving colour at very low lux levels, reducing reliance on constant white-light activation. The HEOP AI platform brings human and vehicle classification directly to the edge without requiring a separate analytics server. Combined with 130dB WDR, IK10 impact resistance, and the -Y anti-corrosion option for exposed sites, this is a camera designed for installers and end-users who need lasting performance in environments where a lower-specification dome would not hold up. It is available at Security Wholesalers as part of the Hikvision Ultra Series range.
Buyer Decision Tips
Motorised Varifocal Lens Adjustment: The 2.7-13.5mm motorised lens allows remote zoom and focus control via the camera’s web interface or a compatible Hikvision NVR. During installation, confirm the final mounting height and angle before locking in the focal length. At 2.7mm the horizontal field of view is approximately 112 degrees, suited to open building frontages or courtyards. At 13.5mm the view narrows to approximately 41 degrees, appropriate for monitoring a specific entry point, corridor end, or gate from a distance. Setting the correct focal length at commissioning avoids unnecessary revisits.
-Y Anti-Corrosion Variant: The -Y suffix on this model indicates the housing carries a NEMA 4X anti-corrosion coating applied over the standard IP67/IK10 shell. If the installation site is not subject to salt air, industrial chemicals, or prolonged exposure to corrosive atmospheres, the anti-corrosion treatment is not a deciding factor but does not reduce performance in standard outdoor environments. Specify the -Y variant for coastal properties within approximately 1km of open water, food processing facilities, or sites with chemical wash-down exposure.

Ideal Use Cases
Transport and Transit Facilities
Airports, train stations, and bus terminals require consistent 24/7 imaging across areas that shift between bright daylight and dim overnight conditions. The Smart Hybrid Light system and 130dB WDR handle this contrast range, and the motorised varifocal lens allows framing to be set for platform-length or concourse-depth coverage from a fixed ceiling position.
Educational Campuses
Schools and universities typically have a mix of indoor and outdoor covered areas, corridors, and open assembly zones. The IK10 vandal-resistant dome housing resists opportunistic tampering, the HEOP human classification reduces false alerts from general movement, and the 8MP resolution supports wide-scene coverage from a single camera across large common areas.
Commercial Building Entrances and Lobbies
High-traffic entry points benefit from the 130dB WDR that manages the contrast between bright exterior daylight through glazing and darker interior surfaces. The 8MP output maintains subject detail across the full entry width, and the dome form factor suits ceiling mounting in covered foyers or awning-sheltered building frontages.
Industrial and Coastal Sites
The -Y anti-corrosion coating makes this model directly suitable for outdoor mounting at ports, marine facilities, coastal industrial yards, and processing plants where salt-laden air or chemical exposure would degrade a standard housing. IP67 and IK10 ratings add further durability for high-exposure outdoor positions.
Government and Critical Infrastructure
Sites requiring a high standard of imaging integrity and on-camera AI processing benefit from the HEOP platform’s human and vehicle classification, which reduces alert workload for monitoring operators. The 8MP resolution, DarkFighter 2.0 low-light performance, and robust vandal-resistant dome housing together support continuous monitoring in security-sensitive environments.
Choosing the Right Model
- Choose this model if: You need an 8MP outdoor dome camera with a motorised varifocal lens for adjustable scene framing, combined with DarkFighter 2.0 low-light colour performance, Smart Hybrid Light up to 40m, HEOP AI human and vehicle classification, and the -Y anti-corrosion housing option for exposed or coastal environments.
- Choose a different model if: The installation is purely indoor with stable lighting and no need for varifocal adjustment – a fixed-lens dome camera at the same resolution will typically be lower cost and simpler to configure for straightforward indoor ceiling positions. Similarly, if long-range directional coverage along a fence line or building perimeter is the primary requirement, a bullet-style camera housing may be more appropriate for that mounting geometry.
FAQs
- What is the difference between the standard model and the -Y variant?
The -Y suffix indicates the camera housing carries an additional NEMA 4X anti-corrosion coating over the standard IP67/IK10 shell. This is specifically designed for environments with ongoing exposure to salt air, industrial chemicals, or corrosive wash-down conditions. Both variants carry the same imaging specifications, lens, and AI platform. If the site is a standard outdoor environment without corrosive exposure, both versions perform identically.
- Can the lens be adjusted after the camera is already installed on the ceiling?
Yes. The 2.7-13.5mm motorised varifocal lens can be adjusted remotely through the camera’s web interface or a compatible Hikvision NVR without physical access to the camera. This means installers can fine-tune zoom and focus after the camera is cabled and mounted, and the field of view can be changed later if site layout or monitoring priorities shift.
- Does this camera produce colour footage at night or does it switch to black and white?
This model uses DarkFighter 2.0 and ColorVu 3.0 technology to maintain colour imaging in very low-light conditions. The Smart Hybrid Light system can activate white-light LEDs to support full-colour capture, or use IR illumination when visible light activation is not appropriate. The mode can be configured based on site requirements, allowing colour or IR output depending on the scene and operator preference.
- What does the HEOP AI platform actually classify, and does it require a separate server?
The HEOP AI-ISP platform runs directly on the camera hardware and classifies detected targets as human or vehicle. This processing happens at the edge without requiring an external analytics server or additional software licence. The classification output is used to filter motion alerts so that events triggered by humans or vehicles are separated from general environmental movement, reducing the volume of non-actionable alerts sent to the recording system or operator.
- What is the horizontal field of view at each end of the focal range?
At the wide end of 2.7mm, the horizontal field of view is approximately 112 degrees, suited to covering broad open areas such as building frontages, courtyards, or transport concourses. At the telephoto end of 13.5mm, the horizontal field of view narrows to approximately 41 degrees, which is appropriate for monitoring a specific entrance, gate, corridor end, or point of interest from a ceiling-mounted position at distance.
- Is the DS-2CD3787G3T-LIZSU(Y) suitable for direct outdoor mounting on a pole or wall bracket?
The IP67 rating confirms the housing is sealed against dust and sustained water ingress, making it suitable for exposed outdoor mounting. The IK10 rating confirms it can withstand significant mechanical impact. For pole or wall bracket installation in open outdoor environments, check that the mounting bracket selected is rated for the camera’s weight and wind load conditions at the site. Compatible Hikvision pole mount brackets are available separately.
