Key Capabilities
8MP 4K Resolution
The 1/1.8″ progressive scan CMOS sensor delivers 4K image quality, giving installers the detail needed to cover wide entry points or car park rows without sacrificing clarity at the edges of the frame.
2.8-12mm Motorised Varifocal Lens
The motorised varifocal lens with autofocus allows remote or on-site adjustment of the field of view from 108.1 degrees wide down to 45.5 degrees, removing the need to reposition the camera head once mounted.
AcuSense Human and Vehicle Classification
Deep learning target classification filters alerts by distinguishing humans and vehicles from other motion sources, reducing the volume of nuisance notifications in busy outdoor environments such as car parks and building perimeters.
DarkFighter Low-Light Performance
With a minimum colour illumination of 0.003 Lux at F1.4 and 0 Lux with IR active, this camera maintains usable colour detail under very low ambient light before transitioning to 40m infrared coverage in complete darkness.
120dB True WDR
120dB wide dynamic range retains detail in both bright and shadowed areas simultaneously, which is critical at building entrances where strong backlight from windows or external sunlight would otherwise wash out faces or number plates.
IP67 and IK10 Rated Construction
Full metal housing with IP67 dust and water resistance and IK10 vandal impact rating makes this dome camera appropriate for exposed outdoor ceilings, entry canopies, and locations where deliberate interference is a risk.
Best For
- Outdoor Vandal-Exposed Mounting Points: IK10 impact resistance and IP67 weatherproofing make this dome suitable for exposed car park ceilings, undercover walkways, and building entry points where weather and deliberate damage are ongoing concerns.
- Sites Where Framing Flexibility Matters: The 2.8-12mm motorised varifocal lens lets installers adjust coverage angle on-site or remotely, which is useful when camera placement is fixed but the monitored area may change, such as retail floors or reception zones.
- High-Alert Commercial Environments: AcuSense human and vehicle classification reduces false triggers in locations with frequent background motion, including landscaped perimeters, outdoor dining areas, and busy driveways.
- Backlit Entry and Exit Points: 120dB true WDR handles strong contrast scenes at building entrances, loading dock doorways, and gatehouse windows where light from outside overpowers standard sensors.
Why Choose the DS-2CD2786G2T-IZS
The DS-2CD2786G2T-IZS stands apart from fixed-lens 8MP domes by pairing 4K resolution with a motorised varifocal lens that adjusts between 2.8mm and 12mm, giving installers genuine flexibility without needing to swap hardware when coverage requirements change. A fixed-lens dome at the same resolution commits you to one field of view from the moment it is mounted. This model also brings AcuSense deep learning classification into the frame, filtering alerts to confirmed human and vehicle motion rather than reacting to every passing shadow or insect near the IR illuminator. The 1/1.8″ DarkFighter sensor performs down to 0.003 Lux in colour mode and extends to 40m IR range in darkness, while the IK10/IP67 housing handles installation in exposed outdoor positions. Audio and alarm interfaces provide integration options for external devices. Available through Security Wholesalers, the DS-2CD2786G2T-IZS suits commercial installers who need adaptable, AI-assisted outdoor dome coverage at 4K resolution.
Buyer Decision Tips
Lens Range vs. Coverage Angle: At 2.8mm the horizontal field of view reaches 108.1 degrees, which is wide enough for a single camera to cover a standard double doorway or reception desk. At 12mm the field narrows to 45.5 degrees, giving a tighter view down a corridor or access lane. Decide your monitoring distance and subject width before commissioning so you know where in the 2.8-12mm range you intend to set the lens, as this affects the camera position and mounting height you plan for.
Audio and Alarm Interface Wiring: This camera includes audio and alarm I/O ports, which allow connection of external microphones, speakers, or alarm triggers. These interfaces require additional wiring beyond the standard PoE Ethernet run. Plan cable routes and junction box space during rough-in if you intend to use these features, particularly in finished ceiling installations where pulling additional cable later is difficult.

Ideal Use Cases
Car Park Ceilings and Columns
The IK10 vandal rating and IP67 housing suit open-deck and basement car parks where cameras face deliberate interference. The motorised varifocal lens allows installers to frame specific bays or access lanes without physically repositioning the camera body.
Building Entry and Lobby Overhangs
The 120dB WDR handles strong backlit conditions at building entrances where exterior light floods the frame. At 2.8mm the wide field of view captures the full width of a double doorway, while the motorised lens allows the installer to tighten coverage to the immediate entry zone.
Outdoor Corridors and Walkways
Exposed covered walkways benefit from the combination of IP67 protection against rain and dust and the tiltable dome head, which can be adjusted to face along a corridor length. AcuSense reduces alerts triggered by wind-blown debris or small animals in these long, narrow zones.
Retail and Commercial Perimeter Walls
The 40m IR range and DarkFighter sensor maintain coverage across outdoor retail perimeters after trading hours. AcuSense human and vehicle classification sends alerts for genuine incursions rather than motion from passing traffic or lighting flicker.
Schools and Institutional Campuses
Multi-building campuses benefit from a motorised varifocal dome that can be re-framed as site layouts change without replacing hardware. IK10 protection reduces vulnerability in student-accessible areas, and the 8MP resolution provides detail across wider courtyards and entry points.
Choosing the Right Model
- Choose this model if: You need 8MP 4K resolution in a vandal-rated outdoor dome with a motorised varifocal lens that can be adjusted remotely or on-site, particularly for car parks, exposed building entries, or commercial installations where field of view flexibility is important.
- Choose a different model if: Your installation is indoors in a low-risk environment and a fixed-lens dome would suffice, as a motorised varifocal dome carries a higher cost than a fixed-focal equivalent and the adjustment capability would not be used. Alternatively, if your site requires active deterrence features such as a strobe or audible alarm, a different camera type with built-in deterrence would be more appropriate.
FAQs
- Does the motorised varifocal lens on the DS-2CD2786G2T-IZS support remote zoom and focus adjustment?
Yes. The 2.8-12mm motorised varifocal lens supports remote zoom and autofocus adjustment via compatible Hikvision NVR or software, allowing installers to frame the scene without physically accessing the camera after it is mounted. This is particularly useful in hard-to-reach ceiling or wall positions. - What is the maximum IR range, and does it adjust automatically with the zoom level?
The DS-2CD2786G2T-IZS has a confirmed IR range of up to 40m using 850nm illuminators. As the lens is zoomed in and the field of view narrows, IR intensity is typically concentrated toward the centre of the frame to maintain subject illumination at longer focal lengths. - How does AcuSense classification reduce false alerts in outdoor locations?
AcuSense uses deep learning to distinguish human and vehicle targets from other moving objects such as animals, foliage, or shadows. Only confirmed human or vehicle motion triggers an alert, which significantly reduces the volume of notifications in outdoor areas with frequent background activity such as car parks or landscaped perimeters. - Is the DS-2CD2786G2T-IZS suitable for mounting in exposed outdoor locations?
Yes. The camera carries an IP67 rating for complete dust exclusion and protection against water jets, and an IK10 rating for resistance to impact. The full metal housing makes it appropriate for exposed outdoor ceiling and wall positions, including undercover car parks, entry canopies, and outdoor corridors. - What does the 120dB WDR rating mean in practical terms for entry point monitoring?
120dB true WDR allows the sensor to simultaneously capture detail in very bright areas and deep shadow within the same frame. At building entrances where strong daylight enters from behind subjects, WDR prevents faces or signage from being overexposed or silhouetted, which is a common limitation of cameras with narrower dynamic range. - Does this camera support two-way audio?
The DS-2CD2786G2T-IZS includes audio and alarm I/O interfaces for connecting external audio devices or alarm triggers. The product data confirms an audio interface rather than a built-in microphone and speaker combination, so two-way audio capability depends on the external devices connected to those ports and your NVR configuration. - Where can I find documentation and support for the DS-2CD2786G2T-IZS?
