Product Overview
Combining Smart Hybrid Light with full-colour AcuSense imaging, the DS-2CD2787G2HT is an 8MP vandal dome camera built for ceiling mounting in demanding indoor and covered outdoor environments where both image quality and lighting flexibility are critical. Featuring a motorised varifocal lens spanning 2.8-12mm, the camera allows installers to dial in field of view without physically adjusting a lens, making it particularly practical for high-ceilings, corridors, or hard-to-access mounting positions. Equipped with a Super Confocal F1.0 aperture and ColorVu technology, it produces full-colour footage even in near-darkness, while Smart mode triggers white light only when a person or vehicle is detected. It also includes AcuSense deep learning to classify people and vehicles separately from environmental motion such as rain or animals. The IK10 vandal resistance and IP67 weather sealing make this dome suited to retail, commercial facilities, covered car parks, and external wall positions where the dome housing needs to withstand physical contact.
Key Capabilities
Smart Hybrid Light with 3 Modes
Operators can select IR-only mode for discreet long-range monitoring, white light mode for constant colour capture, or Smart mode where white light activates automatically when a person or vehicle is detected, then reverts to IR when the scene is clear.
ColorVu with F1.0 Super Aperture
The Super Confocal F1.0 large-aperture lens gathers significantly more light than standard optics, allowing the camera to render vivid colour footage at night without relying solely on artificial illuminators. The precision confocal design maintains sharp focus across both IR and visible light.
AcuSense People and Vehicle Classification
Deep learning algorithms analyse motion events and distinguish people and vehicles from non-relevant triggers such as animals, leaves, and rain. This reduces unnecessary alert notifications and allows footage searches to be filtered by human or vehicle categories.
Motorised Varifocal 2.8-12mm Lens
The motorised varifocal lens covers a 2.8-12mm focal range, enabling remote zoom and focus adjustments from the NVR or camera interface. This is especially useful for ceiling-mounted domes at height where manual lens adjustment would require scaffolding or ladder access.
130dB Wide Dynamic Range
The 130dB WDR rating allows the camera to produce usable detail in scenes with extreme contrast, such as a ceiling-mounted dome covering a lobby entrance where bright exterior light floods in from behind subjects approaching the desk or door.
IK10 Vandal Resistance and IP67 Sealing
The IK10-rated dome housing resists 20 joules of impact force, suitable for mounting in publicly accessible areas such as retail floors, stairwells, and covered outdoor positions. IP67 sealing protects against dust ingress and direct water exposure, covering covered car park and external wall installations.
Best For
- Commercial Ceilings and High-Mount Positions: The motorised varifocal lens allows installers to frame the scene remotely after mounting, removing the need for repeated ladder access in retail stores, warehouses, or facility entrances with high ceilings.
- Entrances and Lobbies with Backlight: The 130dB WDR handles the harsh contrast found at building entrances where exterior daylight creates silhouetting, allowing faces and clothing detail to be captured on people approaching from outside.
- Covered Outdoor and Semi-Exposed Areas: IP67 and IK10 ratings together make this dome suited to covered car parks, building overhangs, and external wall positions where weather exposure and vandalism risk are both present.
- Sites Needing Actionable Night Alerts: AcuSense classification combined with Smart Hybrid Light white light triggering means that when a person or vehicle appears at night, the camera captures full-colour footage and issues an alert categorised by target type rather than general motion.
Why Choose the DS-2CD2787G2HT
The DS-2CD2787G2HT offers a combination that a standard fixed-lens dome at this price tier cannot match: motorised remote zoom, a Super Confocal F1.0 aperture, and Smart Hybrid Light that actively shifts between IR and white light based on target detection rather than simply switching on a floodlight. An entry-level 8MP dome will capture resolution, but it will not give the installer remote lens framing, will not classify people versus vehicles via deep learning, and will not selectively trigger colour illumination only when a relevant target appears. The 130dB WDR is also above what most budget domes provide, making this model a practical choice for contrast-heavy environments. The IK10 housing extends viable mounting locations to publicly accessible areas without needing a separate protective enclosure. Available at Security Wholesalers, the DS-2CD2787G2HT is supplied with local warranty support and is compatible with Hikvision NVR infrastructure.
Buyer Decision Tips
Buyer Tip 1 – Lens Framing at Installation: The 2.8-12mm motorised varifocal range provides substantial flexibility, but the resulting field of view at telephoto end is narrower and better suited to corridor-style coverage or distant zone monitoring rather than wide overhead area coverage. If the mounting point is directly above a large open floor, set the lens closer to 2.8mm. If the camera is positioned at the end of a corridor or above an entry path, the telephoto end delivers tighter framing with the DORI data supporting recognition at up to 43 metres in tele configuration.
Buyer Tip 2 – Smart Mode vs White Light Mode: Smart mode conserves lamp life and avoids constant visible illumination by triggering white light only on detected people or vehicles. If the site requires constant full-colour recording regardless of activity, select white light mode instead. Smart mode is the practical default for most commercial sites, but constant white light mode may be preferred at entrances where colour detail on all passing individuals is required at all times, not just during detected events.

Ideal Use Cases
Retail Store Ceilings
The motorised varifocal lens allows framing adjustments after ceiling mounting without returning to site with a ladder. AcuSense classification filters person-related alerts from background movement, supporting loss prevention workflows in staffed and unstaffed retail environments.
Building Entrances and Lobbies
The 130dB WDR manages the backlight created when exterior daylight enters through glass doors or facades. Smart Hybrid Light ensures people approaching at night are captured in full colour when detected, even when the lobby interior lighting is minimal.
Covered Car Parks
IP67 sealing handles the damp and dusty conditions common in multi-storey or basement car parks. The motorised varifocal lens at tele end supports recognition-level coverage at distances that a fixed wide-angle dome could not match from the same mounting position.
Corridors and Stairwells
The IK10 vandal-resistant dome housing withstands deliberate impact in publicly accessible stairwells and service corridors. The tighter end of the 2.8-12mm varifocal range suits the narrower fields needed in corridor-style monitoring where depth coverage is more important than width.
Commercial Facility Perimeters
Where the dome is mounted under an eave or external soffit, IP67 and IK10 together cover both weather exposure and physical tampering risk. The Smart mode white light trigger activates colour capture specifically when a person or vehicle enters the scene after dark, without constant illumination of the area.
Choosing the Right Model
- Choose this model if: The installation requires remote motorised lens framing after mounting, full-colour night vision via ColorVu, AcuSense people and vehicle classification, and a vandal dome housing rated to IK10 and IP67 for use in publicly accessible or semi-exposed locations.
- Choose a different model if: The mounting location is fully indoors with consistent artificial lighting and no vandalism risk – in that scenario a fixed-lens dome at lower cost will provide equivalent daytime image quality without the premium features of Smart Hybrid Light and motorised varifocal. Alternatively, if the site requires pan, tilt, and zoom control with live operator tracking, a PTZ camera would be more appropriate than this fixed-position dome.
FAQs
- What is Smart Hybrid Light and how does it differ from a standard IR camera?
A standard IR camera runs infrared illumination continuously at night, producing black-and-white footage. Smart Hybrid Light adds white light LEDs and a third mode called Smart mode, where the camera defaults to IR but automatically switches to white light when a person or vehicle is detected. This delivers full-colour footage at the moment it is most needed while reducing unnecessary visible illumination the rest of the time. - Can the motorised varifocal lens be adjusted remotely after installation?
Yes. The motorised varifocal lens on the DS-2CD2787G2HT supports remote zoom and focus adjustment through a compatible Hikvision NVR interface or the camera’s own web interface. This means the lens angle can be set, refined, or changed without physically accessing the dome housing, which is particularly useful for ceiling-mounted or elevated installations. - Is this camera suitable for outdoor mounting without additional protection?
Yes. The DS-2CD2787G2HT carries an IP67 weather protection rating, which covers it against dust ingress and sustained water exposure from rain or cleaning. Combined with IK10 vandal resistance, the housing is appropriate for covered outdoor positions such as building soffits, car park ceilings, and external wall brackets without requiring a separate protective enclosure. - What does AcuSense actually do on this camera?
AcuSense uses deep learning to analyse moving objects in the scene and classify them as either people or vehicles. Motion caused by animals, blowing vegetation, rain, and insects is not classified as a security-relevant trigger. This means event alerts and search results can be filtered by human or vehicle categories, reducing the volume of non-relevant notifications the monitoring system generates overnight. - What DORI distances does the DS-2CD2787G2HT achieve?
In wide configuration (2.8mm end), detection reaches 87 metres and recognition-level detail is available at 17 metres. In tele configuration (12mm end), detection extends to 216 metres and recognition reaches 43 metres. These figures are useful for planning mounting height and angle against the specific zone the camera needs to cover. - Does this camera require a specific NVR to use AcuSense and Smart Hybrid Light features?
The Smart Hybrid Light modes can be configured through the camera’s own web interface independently of the NVR. AcuSense classification and filtered event search are most fully utilised when paired with a compatible Hikvision NVR that supports AcuSense event handling. A non-compatible recorder will still receive the video stream but may not present AcuSense-filtered search or categorised alert triggers. This product is available through Security Wholesalers, where staff can advise on compatible recorder pairing. - How does the F1.0 aperture improve night image quality compared to a standard dome lens?
A standard dome lens typically has an aperture of F1.6 or F2.0. The F1.0 Super Aperture on the DS-2CD2787G2HT allows roughly 2.5 to 4 times more light to reach the sensor compared to an F2.0 lens. Combined with the Super Confocal design that maintains focus across both IR and visible light, this produces sharper and more colourful low-light images without relying entirely on artificial illumination at close range.
