Product Overview
Combining AcuSense deep-learning analytics with a dedicated analogue BNC test output, the DS-2CD2766G2T-IZS-BNC-BLK is a 6MP motorised varifocal dome camera built for commercial ceiling and wall installations where both imaging performance and installation speed matter. Featuring a 1/2.4-inch progressive-scan CMOS sensor delivering 3200 x 1800 resolution, it captures fine detail across large indoor and outdoor areas. Equipped with a motorised 2.8-12 mm varifocal lens, the field of view can be adjusted remotely via NVR or web interface without physically handling the camera after mounting. The BNC output is a practical installer tool, allowing quick lens alignment on a standard analogue test monitor before the IP network is commissioned. Built with IP67 weatherproofing and IK10 vandal resistance, it suits covered outdoor positions such as building entrances, car park overheads, and warehouse ceilings. The black housing variant is suited to dark or architectural environments where a white dome would stand out. This model is well suited to commercial and institutional projects requiring dependable classification-based detection and flexible framing at install time.
Key Capabilities
BNC Analogue Test Output
The BNC output lets installers connect a standard analogue test monitor directly to the camera during setup, confirming the lens angle and scene framing without establishing a full network connection. This reduces setup time on large commercial jobs significantly.
Motorised 2.8-12 mm Varifocal Lens
The motorised varifocal lens covers a horizontal field of view from 106 degrees at wide end to 35 degrees at telephoto, giving installers the flexibility to frame wide car park overheads or tighter entry-point shots from the same camera model, adjusted remotely after mounting.
6MP Resolution at 3200 x 1800
Six megapixel imaging on a 1/2.4-inch CMOS sensor provides enough pixel density to extract useful detail from subjects at distance. At wider zoom settings, a single camera can cover areas that would otherwise require multiple lower-resolution units.
AcuSense Human and Vehicle Classification
AcuSense deep-learning analytics filters motion events by classifying detected objects as humans or vehicles rather than triggering on general motion. This reduces the volume of irrelevant alerts generated overnight in outdoor commercial environments where foliage, weather, or small animals are common triggers.
IR Night Vision to 40 m
With a minimum illumination of 0.003 lux in colour mode and 0 lux with IR active, the camera maintains usable imaging at night. The IR array extends to 40 m, covering the approach distances typical of building entrances, car park lanes, and covered walkways.
IP67 Weatherproofing and IK10 Vandal Resistance
The IP67 rating prevents dust ingress and withstands water exposure at exposed outdoor positions. The IK10 impact rating means the dome casing resists deliberate physical force, making this camera appropriate for public-facing ceilings, car park columns, and building exteriors where tampering is a realistic concern.
Best For
- Commercial Installation Projects: The BNC test output and motorised varifocal lens make this camera well suited to multi-camera commercial installs where fast alignment and remote field-of-view adjustment reduce time on ladders after mounting.
- Car Parks and Building Entrances: The IP67 and IK10 ratings combined with 40 m IR range make it practical for covered outdoor positions where the dome needs to resist both weather and physical interference.
- Sites Requiring Classification-Based Detection: AcuSense human and vehicle classification is well matched to overnight commercial monitoring where reducing false alarm volume from general motion is a priority for operators and monitoring centres.
- Environments Requiring a Discreet Finish: The black dome housing blends into dark ceiling surfaces, architectural metalwork, and contemporary building interiors where a white camera would attract visual attention or conflict with the fitout.
Why Choose the DS-2CD2766G2T-IZS-BNC-BLK
The DS-2CD2766G2T-IZS-BNC-BLK stands apart from standard 6MP dome cameras because of its BNC analogue output, a feature absent from most IP-only dome models at this resolution. For installers commissioning multiple cameras across a site, the ability to verify lens angle on a portable test monitor before locking off the mount bracket is a practical time-saver. The motorised 2.8-12 mm varifocal lens extends that flexibility further, allowing zoom and focus to be dialled in remotely after the camera is secured. AcuSense classification adds a layer of intelligence that a basic motion detection camera cannot match, filtering events down to human and vehicle detections that are actionable. The IK10 vandal-resistance rating and IP67 weather sealing mean it can be placed in outdoor positions that would compromise a standard indoor dome. Available through Security Wholesalers, the DS-2CD2766G2T-IZS-BNC-BLK is backed by H.265+ compression to keep storage load manageable across multi-channel NVR deployments.
Buyer Decision Tips
BNC Variant vs. Standard Model: The BNC output on this model is specifically intended as an installation and test aid, not a secondary recording output. Final video recording and live monitoring run through the IP network connection only. If your project does not involve site testing with analogue test monitors, a non-BNC variant of the same camera will deliver identical IP performance. Choose this BNC variant when your installation workflow involves portable analogue monitors for lens alignment, or when maintenance access to camera views without network login is a regular requirement.
Motorised Zoom and Mounting Height: The 2.8-12 mm motorised varifocal range works best when the camera is mounted between 2.5 m and 4 m to achieve practical DORI distances for detection and identification. At wider zoom settings from 2.8 mm the camera covers broad areas such as car park bays or warehouse floors. At the 12 mm telephoto end it narrows to a focused corridor or entry channel. Plan the mounting position and target scene before finalising the bracket and cable length, as the motorised adjustment compensates for framing but not for a fundamentally unsuitable mounting location.

Ideal Use Cases
Commercial Car Parks
The IP67 and IK10 ratings make this dome suitable for car park column and ceiling positions exposed to weather and potential impact. AcuSense vehicle classification assists in filtering out irrelevant motion events from parked cars shifting in wind or light reflections.
Building Entrances and Lobbies
Ceiling mounting above entry doors benefits from the motorised zoom to frame the entry channel precisely. The 120 dB True WDR handles the backlight challenge common at glass entry doors, where exterior daylight behind subjects would otherwise wash out facial and clothing detail.
Warehouse and Industrial Interiors
Mounted from ceiling height in warehouses, the 2.8-12 mm varifocal range can be adjusted to cover broad storage bay aisles or narrowed to watch loading dock access points. The black dome finish suits industrial ceiling environments where white housings look out of place.
Multi-Site Commercial Installs
Installers commissioning multiple cameras across large commercial sites benefit directly from the BNC test output, using a portable analogue monitor to confirm each camera’s angle before closing off cable penetrations and locking brackets, avoiding repeat access visits.
Covered Outdoor Perimeters
Under-eave and covered walkway positions that experience periodic rainfall and condensation are served well by the IP67 seal. The 40 m IR range covers typical perimeter approach distances at night, and AcuSense human classification focuses alert generation on genuine intrusion events rather than environmental triggers.
Choosing the Right Model
- Choose this model if: You need a 6MP outdoor dome with motorised varifocal framing flexibility, AcuSense classification to reduce false alerts, and a BNC test output to speed up lens alignment during installation or maintenance.
- Choose this model if: Your installation environment has dark or architectural ceilings where the black housing blends in better than a white dome, or where a white finish would be visually inappropriate for the space.
- Choose a different model if: Your project requires full-colour night imaging rather than IR-based black-and-white low-light performance. A full-colour dome variant with a white-light supplement would be a better match for environments where colour retention at night is critical for identification purposes.
- Choose a different model if: The BNC test output is not a workflow requirement and cost is a constraint. An IP-only dome at the same resolution without the BNC output may be available at a lower price point if the analogue test function adds no value to your specific installation process.
FAQs
- What is the BNC output on the DS-2CD2766G2T-IZS-BNC-BLK actually used for?
The BNC output provides an analogue video signal from the camera that can be viewed on a standard test monitor or portable LCD screen. It is intended as an installation and maintenance aid, allowing the installer to verify the camera’s field of view, lens position, and aim before the IP network is set up. It does not carry recorded footage and should not be connected to an analogue DVR as a primary recording feed. - How does the motorised varifocal lens get adjusted after installation?
The 2.8-12 mm motorised lens can be adjusted remotely through a compatible Hikvision NVR’s camera management interface or through the camera’s own web interface via a browser. This removes the need to physically access the camera after mounting to turn a manual zoom ring, which is particularly useful when the camera is installed at ceiling height or in a difficult-to-reach position. - Does this camera work in complete darkness?
Yes. The DS-2CD2766G2T-IZS-BNC-BLK switches to IR mode at 0 lux, meaning it can operate with no ambient light at all. The IR array illuminates to a range of up to 40 m, producing monochrome imaging in full darkness. In low-light conditions above 0.003 lux the camera retains colour imaging at F1.6 aperture before transitioning to IR. - What does AcuSense classification do differently from standard motion detection?
Standard motion detection triggers on any pixel change within the detection zone, including wind-blown foliage, rain, insects crossing the sensor, or headlight sweeps. AcuSense applies deep-learning analysis to classify moving objects as humans or vehicles before generating an alert. Events triggered by non-human, non-vehicle motion are filtered out, which reduces the volume of notifications sent to monitoring systems or operators significantly on busy outdoor sites. - Is the dome housing suitable for outdoor installation?
Yes. The DS-2CD2766G2T-IZS-BNC-BLK carries an IP67 rating, meaning it is fully dust-tight and can withstand water immersion at shallow depth, covering all typical outdoor rain and wash-down scenarios. The IK10 impact rating confirms the dome casing resists up to 20 joules of impact force, which is sufficient for vandal-exposed positions on building exteriors, car park structures, and public-facing ceilings. - What power options does this camera support?
The camera accepts 12 V DC with a tolerance of plus or minus 25 percent, or Power over Ethernet via IEEE 802.3af Class 3, drawing a maximum of 9.5 W. PoE simplifies cabling on new installations by carrying both data and power over a single CAT5e or CAT6 cable run to the camera, while the 12 V DC option suits retrofits into existing cable infrastructure. - Where can I find compatible mounting brackets for the DS-2CD2766G2T-IZS-BNC-BLK?
Compatible mounting accessories for the DS-2766 series are listed on the product page, including wall mount, pendant, and pole mount bracket options suited to ceiling, wall, and structural column positions. Security Wholesalers stocks a range of Hikvision mounting brackets for this series, and the existing product page includes a bracket selection table to assist with choosing the correct fitting for your installation scenario.
