Product Overview
Combining Smart Hybrid Light technology with ColorVu colour imaging, the DS-2CD2787G2HT-LIZS is an 8MP 4K motorised varifocal dome camera built for ceiling-mounted installations where both image detail and low-light performance are essential. Housed in an IP67 and IK10-rated dome casing, it suits covered outdoor areas, building entrances, retail floors, car park ceilings, and commercial corridors where the dome profile keeps the installation tidy and tamper-resistant. Featuring a 2.8 to 12mm motorised varifocal lens, the camera allows installers to adjust framing remotely without physically repositioning the unit, a practical advantage in hard-to-reach ceiling positions. It also incorporates 130 dB wide dynamic range for scenes with mixed lighting conditions such as foyer entrances or shopfronts. It is well suited to sites that require consistent identification-grade imaging around the clock, with Smart mode automatically switching between IR and colour depending on whether motion is detected in the scene.
Key Capabilities
8MP 4K Resolution
The 1/1.8″ progressive scan CMOS sensor delivers a 3840 x 2160 image, providing the detail needed for identification at distance in commercial ceiling-mount positions. DORI tele figures show detection at 216m and identification at 22m.
Smart Hybrid Light with ColorVu
In Smart mode, the camera operates on infrared illumination until a vehicle or person enters the scene, at which point white light activates for full-colour imaging. This reduces unnecessary light pollution while still capturing colour detail when it counts.
Motorised Varifocal Lens (2.8-12mm)
The motorised lens allows remote focal length adjustment from 2.8mm (112.3 horizontal FOV) to 12mm (41.2 horizontal FOV), making it straightforward to fine-tune framing after installation without ladder access or physical lens adjustment.
130 dB Wide Dynamic Range
Scenes with strong backlighting such as entrance lobbies, shopfronts with large windows, or covered carpark entries can challenge standard cameras. The 130 dB WDR maintains legible detail in both bright and shadowed areas of the same frame.
IP67 and IK10 Protection
Full dust ingress protection and resistance to water jets makes this dome suitable for covered outdoor positions. IK10 impact resistance adds physical tamper tolerance appropriate for publicly accessible areas such as retail corridors or building entrances.
H.265+ Compression
Efficient H.265+ encoding reduces storage consumption and network bandwidth compared to older compression standards, allowing longer retention periods on an NVR without increasing drive capacity or compromising recording resolution.
Best For
- Commercial Building Entrances: The 130 dB WDR handles the mixed lighting typical of lobby or foyer environments, while IK10 vandal resistance makes the dome casing appropriate for publicly accessible entry points.
- Covered Car Parks and Loading Areas: The motorised varifocal lens allows the camera to be adjusted to cover specific bays or lanes after installation, and Smart Hybrid Light activates colour imaging when vehicles or people are detected.
- Retail Floors and Corridors: The discreet dome form factor blends into ceiling-mounted positions, while 8MP resolution provides the image quality needed to extract usable detail from a wide field of view at standard retail ceiling heights.
- Sites Requiring Low-Light Colour Capture: With a minimum illumination of 0.0028 lux at F1.2 and ColorVu technology, the camera produces colour imagery in conditions where standard cameras would produce only black-and-white or degraded footage.
Why Choose the DS-2CD2787G2HT-LIZS
The DS-2CD2787G2HT-LIZS stands apart from standard fixed-lens dome cameras through the combination of motorised varifocal flexibility and Smart Hybrid Light behaviour. A basic 4MP or fixed-lens dome cannot match the framing control a 2.8 to 12mm motorised lens provides, nor can it replicate the automatic switching between IR and white-light colour modes based on motion events. The 4K sensor on a 1/1.8″ CMOS chip delivers DORI identification distances that lower-resolution models cannot achieve in the same ceiling-mounted position. At the same time, the IK10 dome housing handles the physical demands of commercial and semi-public environments better than a lighter turret or bullet form factor would. Available through Security Wholesalers, this camera is suited to installers and integrators who need a single versatile dome that handles 4K detail, extreme backlighting, and low-light colour capture in one unit.
Buyer Decision Tips
Lens Zoom Range and Ceiling Height: The 2.8 to 12mm motorised range covers a wide spread of ceiling heights and zone sizes. At 2.8mm the horizontal FOV reaches 112.3 degrees, useful for wide-area coverage at lower ceilings. At 12mm the FOV narrows to 41.2 degrees, which is appropriate for longer corridor runs or focused entry points. Confirm the ceiling height and the zone you need to cover before assuming the widest or tightest setting will suit the site.
Smart Hybrid Light Mode Selection: The camera supports 3 lighting modes. 24/7 colour mode keeps white light active continuously. IR mode provides black-and-white imaging in dark conditions. Smart mode, which is the key differentiator for this model, uses IR by default and switches to white light only when a person or vehicle is detected. For sites where constant white light illumination would be intrusive or unwanted, Smart mode is the recommended configuration and should be set during commissioning.

Ideal Use Cases
Retail Store Ceilings
The dome form factor mounts flush to ceilings without the visible profile of a bullet camera. The 8MP sensor and motorised zoom allow one camera to cover a wide sales floor at 2.8mm or zoom in on a specific aisle or counter position at 12mm.
Building and Office Foyers
The 130 dB WDR addresses the backlight challenge common in foyers where large glass facades or bright exterior light create difficult exposure conditions. The IK10 casing handles the physical access demands of a public lobby environment.
Covered Car Parks
Smart Hybrid Light activates white-light colour imaging when a vehicle or pedestrian enters the scene, capturing clothing colour, vehicle colour, and plate area with more detail than IR-only cameras in the same position.
Commercial Corridors and Stairwells
In corridor ceiling positions where access for lens adjustment is difficult after installation, the motorised varifocal lens allows framing to be set or corrected remotely. The tele DORI identification range of 22m suits longer corridor runs.
Semi-Outdoor Covered Areas
With IP67 dust and moisture resistance and IK10 impact tolerance, the dome is suited to covered walkways, awning-protected loading dock areas, and undercover building perimeters where weather exposure is partial rather than direct.
Choosing the Right Model
- Choose this model if: You need 4K resolution in a ceiling-mounted dome with motorised lens adjustment, IK10 vandal resistance, and the ability to automatically switch between IR and colour imaging based on detected motion. The Smart Hybrid Light feature is a key differentiator for sites where constant white-light illumination is not appropriate.
- Choose a different model if: The installation site is fully exposed outdoors on a wall without shelter, where a bullet housing with directional mounting would provide a more weather-resistant and purpose-built configuration. Equally, if the budget does not require 4K or motorised zoom, a fixed-lens 4MP dome will cover many of the same indoor ceiling positions at a lower cost.
FAQs
- What is Smart Hybrid Light and how does it differ from standard ColorVu?
Standard ColorVu cameras use white light continuously to produce colour imagery at night. Smart Hybrid Light adds a third operating mode where the camera uses infrared illumination by default and switches to white light only when a person or vehicle is detected in the frame. This means colour detail is captured when an event occurs, without the constant white light output of a full-time ColorVu setup. - What ceiling heights is the 2.8 to 12mm motorised lens suited to?
At 2.8mm the horizontal FOV of 112.3 degrees suits lower ceilings of 3 to 4 metres where wide-area coverage of a room or sales floor is required. At 12mm the narrower 41.2 degree FOV is more appropriate for higher ceilings, longer corridors, or focused views of a specific entry point. The motorised adjustment allows the framing to be refined after installation without physically accessing the camera. - Is the DS-2CD2787G2HT-LIZS suitable for outdoor installation?
Yes. The IP67 rating confirms protection against dust ingress and water jets, and the IK10 dome casing provides resistance to physical impact. The camera is suited to covered outdoor positions such as undercover car parks, entry canopies, and covered walkways. Direct exposure to driving rain in an unsheltered wall-mount position would be better addressed by a bullet housing, but the dome handles most semi-outdoor ceiling-mounted environments. - What DORI identification distance does this camera achieve?
At the tele end of the motorised zoom (12mm), the camera achieves an identification distance of 22 metres and a detection distance of 216 metres. At the wide end (2.8mm), the identification distance is 9 metres with detection at 87 metres. The appropriate zoom setting will depend on the distance to the subject in the scene. - Does this camera support two-way audio?
The confirmed product specifications do not include a built-in microphone and speaker. Two-way audio capability is not confirmed for this model and should not be assumed based on the available product data. - What compression format does the DS-2CD2787G2HT-LIZS use and how does it affect storage?
The camera uses H.265+ compression, which is the most efficient format in the Hikvision codec range. Compared to H.264, H.265+ can significantly reduce file sizes for equivalent image quality, allowing longer retention periods on the same NVR storage capacity or reducing the drive size required for a given retention target at 4K resolution. - Where can I find the full datasheet for this camera?
