Product Overview
Built for outdoor perimeter coverage where distance matters, the DS-2CD2T66G2-4I is a 6MP AcuSense Gen 2 bullet camera capable of illuminating scenes up to 80 metres using EXIR technology. The bullet housing makes it well suited to wall and ceiling mounting along building facades, fence lines, driveways, loading areas, and car parks where a clearly directed field of view is required. Featuring Hikvision’s second-generation AcuSense deep learning engine, the camera distinguishes between human and vehicle movement and filters out irrelevant triggers such as small animals, wind-blown foliage, and passing headlights. Equipped with 120dB Wide Dynamic Range and DarkFighter low-light technology, it maintains usable image detail across high-contrast scenes. It also supports on-board storage up to 128GB via microSD, PoE (802.3af), and multiple compression formats including H.265+. This makes it a practical choice for commercial and industrial sites where analytic accuracy and extended night-time reach are both priorities.
Key Capabilities
AcuSense Gen 2 Analytics
Second-generation deep learning classifies moving targets as people or vehicles in real time. This reduces nuisance alerts caused by animals, foliage, or lighting changes, and generates searchable alarm events that make reviewing recorded footage for specific incidents significantly faster.
80m EXIR Illumination
The EXIR array provides uniform infrared coverage out to 80 metres without the hot-spot effect common in standard IR cameras. This makes the DS-2CD2T66G2-4I suitable for monitoring long outdoor approaches, driveways, and extended fence lines in complete darkness.
6MP Resolution at 3072 x 2048
Recording at up to 3072 x 2048 pixels at 20fps provides enough image detail to identify individuals or read vehicle features at distance. The higher pixel count compared to 4MP or 2MP alternatives gives installers more flexibility when cropping or zooming into recorded footage post-event.
120dB Wide Dynamic Range
A 120dB WDR rating allows the camera to capture usable detail in scenes with extreme light variation, such as a building entrance with bright sky behind it or a car park entrance where headlights hit the lens directly during night hours.
DarkFighter Low-Light Performance
DarkFighter technology delivers a minimum colour sensitivity of 0.003 Lux at F1.6 with AGC enabled and 0 Lux when IR is active. This extends usable colour imaging into dimly lit outdoor environments before the camera switches to infrared mode.
Flexible Power and Local Storage
PoE (802.3af, Class 3) allows single-cable installation to compatible switches or NVRs. On-board microSD storage up to 128GB provides a local recording buffer, which is useful for edge-based recording or as a redundancy option if network connectivity is interrupted.
Best For
- Long-Range Outdoor Coverage: The 80m EXIR range makes this camera suited to extended perimeter monitoring such as long driveways, fence lines, rear yards, and loading bay approaches where shorter-range cameras would leave blind spots at night.
- High-Contrast Entry Points: The 120dB WDR helps maintain image quality at entrances, boom gates, and building facades where direct sunlight or vehicle headlights regularly cause overexposure on lower-spec cameras.
- Commercial and Industrial Sites Requiring Targeted Alerts: AcuSense Gen 2 allows security teams to configure alerts specific to human or vehicle intrusion, reducing the time spent reviewing irrelevant motion events across large sites.
- Installations Needing Edge Storage Redundancy: On-board storage up to 128GB provides a local recording backup that functions independently of the network recorder, useful for remote sites or locations with intermittent connectivity.
Why Choose the DS-2CD2T66G2-4I
The DS-2CD2T66G2-4I separates itself from standard 6MP bullet cameras through the combination of AcuSense Gen 2 deep learning and 80-metre EXIR reach. Where a basic motion-triggered camera generates alerts from every cat, wind gust, or shadow, the AcuSense engine classifies events by target type, making alarms actionable rather than noise. The 120dB WDR and DarkFighter sensor extend the camera’s operational range across challenging lighting conditions that would degrade image quality on a standard sensor. H.265+ compression reduces storage consumption without sacrificing resolution, making it compatible with smaller NVR configurations. For installers and end users looking for a proven outdoor bullet with genuine analytic capability rather than a basic motion detector, the DS-2CD2T66G2-4I is available through Security Wholesalers alongside compatible Hikvision recording and mounting accessories.
Buyer Decision Tips
IR Range vs. Lens Selection: The DS-2CD2T66G2-4I ships with a 2.8mm fixed lens, which provides a wide field of view suited to shorter to mid-range coverage. While the 80m IR range gives excellent night reach, the wide-angle lens means subject detail at 60 to 80 metres will be limited. If you need to identify facial features or read licence plates at 30 metres or beyond, consider a narrower lens variant. If your priority is broad scene coverage across a driveway or yard approach with target classification alerts, the 2.8mm and 80m IR combination works well together.
PoE Budget and Class Rating: This camera draws PoE at 802.3af Class 3, which has a maximum power delivery of 15.4W. Confirm that your switch or NVR’s PoE port supports Class 3 on the specific port you intend to use. Some budget PoE switches limit total PoE budget across all ports, which can cause cameras to fail to power when multiple high-draw devices share the switch under load.

Ideal Use Cases
Perimeter Fence Lines
The 80m EXIR range covers extended stretches of fencing in complete darkness. AcuSense Gen 2 ensures alerts are only triggered by people or vehicles crossing the line, not by vegetation movement or small animals.
Industrial Yard and Warehouse Approaches
The bullet housing mounts directly to warehouse walls and eaves, directing coverage across yard entrances and loading areas. Vehicle classification alerts are particularly useful for after-hours monitoring of goods-in and goods-out zones.
Commercial Car Parks
120dB WDR handles the contrast between lit signage, headlight glare, and shadowed parking bays. The camera’s 6MP resolution provides enough detail across a wide bay layout for post-event review of incidents.
Long Residential Driveways
For properties with extended driveways or rural frontages, the 80m night reach provides coverage that shorter-range cameras cannot match. A single camera mounted at the building can cover the full driveway length in infrared mode.
Remote or Off-Grid Monitoring Points
On-board storage up to 128GB via microSD allows the camera to record locally if network access is unavailable or interrupted. This makes it suitable for remote gate entries, rural outbuildings, and construction sites with limited network infrastructure.
Choosing the Right Model
- Choose this model if: You need an outdoor bullet camera with genuine 80m night reach, AcuSense human and vehicle classification, and 120dB WDR for high-contrast environments such as driveways, perimeter fences, car parks, or warehouse approaches.
- Choose a different model if: Your primary requirement is full-colour night imaging in low-light conditions rather than infrared reach. A ColorVu-equipped bullet camera would be more appropriate where colour information in darkness is a priority over IR range. If PTZ capability or a motorised zoom lens is needed for variable focal coverage, a different camera type would better suit that requirement.
FAQs
- What does AcuSense Gen 2 actually do differently compared to standard motion detection?
Standard motion detection triggers on any pixel change in the scene, including leaves, rain, shadows, and small animals. AcuSense Gen 2 uses a deep learning engine to classify moving objects specifically as people or vehicles. This means alarm events are only generated for relevant targets, and those events are tagged and searchable in recorded footage, which can significantly reduce the time required to locate a specific incident during review.
- Is the 80m IR range achievable in all outdoor conditions?
The 80m EXIR specification is the maximum IR illumination distance under ideal conditions. In practice, heavy rain, fog, or dense foliage between the camera and the subject will reduce effective range. For installations where weather conditions regularly affect visibility, treat 80m as the upper limit and plan camera positions with some margin if subject identification at that distance is critical.
- What lens size does the DS-2CD2T66G2-4I come with?
This model is equipped with a 2.8mm fixed lens. The 2.8mm focal length provides a wide field of view, making it well suited to capturing broad scenes such as driveways, open yards, and car parks. It is not designed for narrow-angle long-distance identification tasks where a longer focal length would be required.
- Can this camera record without a network video recorder?
Yes. The DS-2CD2T66G2-4I supports on-board microSD storage up to 128GB. When a microSD card is installed, the camera can record footage locally and independently of an NVR. This is useful for standalone installations, edge recording setups, or as a redundancy layer in sites where NVR connectivity cannot always be guaranteed.
- Does this camera require a PoE switch or can it run on 12VDC?
The DS-2CD2T66G2-4I supports both PoE (802.3af, Class 3) and 12VDC power. PoE is the most common installation method as it allows power and data over a single Ethernet cable. A 12VDC supply is an alternative for locations where a PoE switch is not available or where existing cabling infrastructure uses a direct power supply arrangement.
- What weather rating does the DS-2CD2T66G2-4I carry and is it suitable for direct weather exposure?
The camera is rated IP67, which means it is fully protected against dust ingress and against the effects of temporary water immersion. IP67 is appropriate for outdoor installation in exposed positions including eaves, external walls, and pole mounts in Australian conditions. It does not carry an IK vandal resistance rating, so for installations where physical impact is a risk, a vandal-rated enclosure or housing should be considered.
- Where can I find the datasheet and installation guide for this camera?
The HIK-2CD2T66G2xIx datasheet, quick start guide, and user manual are all available in the Additional Information section below. Security Wholesalers provides these documents directly on the product page so installers can confirm specifications before purchase and reference wiring and configuration details during installation.
