Detailed specifications and benefits
The DS-2CD2T66G2-2I packs a number of hardware and software features that make it a robust option for many outdoor surveillance scenarios. Below are the core specification areas with practical benefits for real‑world use.
- Sensor and resolution:A 1/2.4" progressive‑scan CMOS sensor captures 6 MP (3200 × 1800) video. The higher pixel count translates to sharper images and improved ability to zoom in on faces, license plates and other details without losing clarity.
- Fixed 6 mm lens:With an approximate horizontal field of view of 51° and vertical ≈ 26°, the lens suits fixed monitoring of gates, entrances, car parks and perimeter lines where mid‑range coverage and detail are needed.
- DarkFighter technology:Enables colour imaging at very low light (colour 0.003 Lux @ F1.6), which means better situational awareness and identification at night without relying solely on IR. When detailed colour is vital (vehicle colour, clothing), DarkFighter is an advantage over standard B/W night modes.
- IR (EXIR):An IR variant (the -2I model) provides up to ~60 m of illumination for true night coverage when colour is unavailable.
- 120 dB True WDR:Handles scenes with bright and dark areas—entrances with backlighting or reflective surfaces—preserving detail in highlights and shadows.
- 3D DNR, BLC/HLC:Noise reduction and exposure controls improve image clarity in low light and against strong lights such as headlights.
- AcuSense human/vehicle classification:On‑camera AI filters out many false alarms from motion sources that are not people or vehicles. This reduces notification fatigue and saves operator time and storage by focusing on relevant events.
- Compression:H.265+/H.265/H.264+/H.264 support plus multiple streams helps balance bandwidth and storage needs while maintaining image quality for forensic review.
- PoE and 12 VDC:Power over Ethernet simplifies installation by delivering data and power over a single cable (IEEE 802.3af). A 12 VDC option allows legacy power setups.
- Local storage:microSD support up to 256 GB provides edge recording as a backup or for installations without network recording.
- ONVIF and network compatibility:Standard IP camera networking and ONVIF support (confirm via datasheet) enable integration with many NVRs and VMS platforms, including Hikvision NVRs for full feature access.
- IP67 rating:Fully protected against dust and water jets—suitable for exposed outdoor mounting.
- Operating temperature:Approximately −30 °C to 60 °C for reliable operation in varied climates.
- Compact bullet form:Dimensions and mounting options make for straightforward installation on walls, eaves and poles.
Use cases and scenarios where this camera excels
The combination of resolution, low‑light performance and AI classification makes the DS-2CD2T66G2-2I a versatile choice for several common surveillance applications:
When monitoring long stretches of perimeter fencing or gated property lines, the 6 MP sensor provides detail across moderate distances and the AcuSense analytics reduce nuisance alerts from windblown foliage and small animals.
DarkFighter colour imaging and IR support deliver visibility during night hours—useful for identifying vehicle colours and occupant movement. The camera's WDR also helps for scenes where headlights or streetlights might otherwise obscure detail.
Facing entrances, the camera balances field of view and detail. AcuSense classification makes it easier to focus on people and vehicles, supporting access control and incident review.
For small and medium businesses, and multi‑site deployments, the camera’s affordability, PoE capability and ONVIF compatibility make it easy to standardise devices across locations and manage centrally through compatible NVRs or cloud systems.
How it compares with similar cameras on the market
Within its class, the DS-2CD2T66G2-2I competes on imaging, analytics and price. Here are some practical comparison points:
- Versus basic 2–4 MP cameras:The 6 MP resolution of this model delivers better detail for identification and evidence. Where 2–4 MP cameras might be adequate for general monitoring, the 6 MP option is preferable for applications requiring more forensic detail.
- Versus Hikvision lower‑tier models:AcuSense and DarkFighter are differentiators. Lower‑tier Hikvision cameras lacking AcuSense incur more false alarms and may not capture as much colour detail at night. Choosing the AcuSense model can save time and storage by reducing irrelevant alerts.
- Versus competitor offerings (Dahua, Axis, Uniview, etc.):Many competitors offer similar features (high resolution, WDR, advanced low‑light tech). Axis and other premium brands may provide superior build quality, advanced analytics or broader certification sets at higher prices. Dahua and Uniview often offer comparable specifications at similar price points. The decision often comes down to integration preferences (Hikvision NVRs/VMS), specific analytics performance, support and regional availability.
- Value proposition:At a suggested price of $149.99, the DS-2CD2T66G2-2I delivers an attractive balance of AI analytics, low‑light colour capability and outdoor robustness for the price‑sensitive installer or business owner.
Customer feedback and typical reviews
Publicly available platform reviews specific to this exact model may be limited. However, installer and end user feedback on Hikvision AcuSense/DarkFighter models generally highlights several recurring themes:
- Positive:Many users praise the improved identification from 6 MP resolution and the colour night images from DarkFighter in low‑light conditions. Installers appreciate PoE for simpler cabling and the rugged IP67 housing for outdoor reliability.
- Practical benefits:Users often note fewer false alarms and more relevant event captures after enabling AcuSense filtering, which reduces unnecessary notifications and streamlines review workflows.
- Considerations:Some integrators mention that to unlock the full feature set (AI functions, firmware updates, integration with specific NVRs) it's important to use compatible Hikvision recorders or ensure ONVIF interoperability is tested in advance. As with most security equipment, proper installation, placement and configuration are key to achieving expected performance.
Conclusion: Why choose the DS-2CD2T66G2-2I(6mm)(C)?
