Introduction to the 2MP AcuSense Bullet Camera (DS-2CD2T26G2-4I(2.8mm)(D))
The DS-2CD2T26G2-4I(2.8mm)(D) is a purpose-built 2 MP AcuSense fixed bullet network camera from Hikvision designed for reliable outdoor perimeter and site surveillance. Combining DarkFighter low-light imaging with Hikvision's AcuSense deep-learning analytics, this camera delivers clearer colour images at night, strong performance in challenging lighting, and reduced false alarms through human/vehicle classification. With an IP67-rated enclosure, PoE support and flexible storage options, it is positioned as an accessible yet capable option for businesses and homeowners seeking intelligent, always-on outdoor monitoring. The suggested retail price for this model is approximately $169 (cost price example: $120.01), making it a competitive choice in the entry-to-mid level IP CCTV market.
- Resolution:2 MP (1920 × 1080) for clear, full HD imaging.
- Low-light performance:DarkFighter technology delivers colour imaging down to 0.002 Lux; IR support takes B/W to 0 Lux when needed.
- Analytics:AcuSense deep-learning for accurate human and vehicle classification, helping to cut false alarms.
- Lens and coverage:Fixed 2.8 mm F1.4 lens with approximately 107° horizontal field of view — ideal for wide area coverage.
- Durability:IP67 weatherproof rating for reliable outdoor operation.
- Power & storage:PoE (802.3af) or 12 VDC power options and on-board microSD support up to 256 GB.
Under the hood the DS-2CD2T26G2-4I offers a focused specification set intended to balance image quality, analytic intelligence and cost-efficiency. The 1/2.8" progressive-scan CMOS sensor captures 2 MP video at up to 25/30 fps depending on region, and supports efficient compression formats including H.265/H.264 and enhanced H.265+/H.264+ variants to reduce bandwidth and storage needs.
- Lens:Fixed 2.8 mm, F1.4 — a wide-angle option that is well suited to entranceways, driveways, building frontages and car parks where broad coverage matters.
- DarkFighter low-light technology:Produces usable colour images in very low ambient light (colour to 0.002 Lux) and pairs with Smart IR (850 nm) for clear night views; ideal when colour information at night (clothing, vehicle colours) aids investigation.
- 120 dB WDR:Wide dynamic range handles scenes with strong backlight or mixed lighting so faces and license plates remain discernible in contrast-heavy environments.
- AcuSense analytics:Deep-learning driven human/vehicle classification reduces alarm nuisance from small animals, leaves or light changes and enables targeted perimeter protection and smart event triggers.
- Storage:On-board microSD support (up to 256 GB) allows local recording alongside networked NVR options — useful for redundancy or remote sites where continuous network recording may be limited.
- Networking:10/100 Mbps Ethernet with standard protocols and ONVIF support makes the camera compatible with a wide range of VMS/NVR solutions and third-party systems.
- Power:PoE (802.3af) simplifies installation by carrying power and data over a single cable; a 12 VDC option provides flexibility where PoE is not available.
- IP67 rating:Dust- and water-resistant enclosure suitable for exposed outdoor locations. Operating temperature range from −30 °C to 60 °C supports deployment in many climates.
Practical installation notes: confirm the 2I vs 4I variant when ordering — IR range varies by model (up to ~60 m for 2I and ~80 m for 4I in typical conditions). Also verify local compliance requirements (for example NDAA restrictions in some procurement scenarios) and ensure firmware updates and default credential hardening are performed during commissioning.
The DS-2CD2T26G2-4I(2.8mm)(D) is particularly well suited to outdoor perimeter and wide-area monitoring where intelligent analytics and low-light colour imaging add real value. Typical deployments include:
- Commercial properties and retail exteriors:Monitor shopfronts, loading bays and customer parking areas. AcuSense filtering reduces alarms from non-relevant motion so security teams can focus on vehicle and human events.
- Residential perimeter security:Homeowners and residential complexes benefit from clear night-time colour imagery and the wide 2.8 mm field of view to monitor driveways, gates and garden boundaries.
- Car parks and small lots:Capture wide areas with the 2.8 mm lens and use classification to detect vehicles entering/leaving zones, supporting loss prevention and incident investigation.
- Logistics and delivery bays:Keep a persistent eye on delivery activity with improved night colour detail, helping to identify vehicles and personnel during late shifts or early mornings.
- General outdoor surveillance:For schools, small business campuses, and civic spaces, the camera offers a robust and cost-effective option when combined with an appropriate VMS or recorder.
When considering the DS-2CD2T26G2-4I you will likely compare it to other 2 MP bullet or turret cameras and to higher resolution or specialised low-light models. Key comparative points:
- AcuSense vs basic motion detection:AcuSense’s deep-learning classification typically delivers far fewer false alarms compared with simple pixel-change or motion-based detection used in entry-level cameras. This is a material operational advantage where alarm verification workload matters.
- DarkFighter vs Starlight:Different vendors market their low-light technologies (Hikvision DarkFighter, other brands’ Starlight or low-light sensors). DarkFighter is tuned for retaining colour as long as there is minimal ambient illumination, which helps investigations where colour is an identifier. Some competitors may offer slightly higher resolution or better low-light performance at higher price points.
- 2.8 mm wide lens vs telephoto variants:The wider 2.8 mm lens gives good situational awareness but will not capture long-distance detail like a telephoto lens. If long-range license plate capture is a priority, a camera with a telephoto or varifocal lens or higher resolution (4 MP+) should be considered.
- IP rating and ruggedness:IP67 is common for outdoor models; if impact resistance (IK rating) or extreme-temperature operation is required, review product variants or industrial-grade offerings.
- Price-to-performance:At a suggested price around $169, this model offers strong value for organizations seeking intelligence-driven detection without moving into significantly higher-cost 4K or thermal systems.
Public reviews for this class of Hikvision AcuSense cameras tend to highlight the following recurring themes (summarised from user feedback and installer commentary):
- "Reliable night colour — we can identify vehicle colours at night in many cases, which helps investigations."
- "AcuSense dramatically cut false alarms from trees and animals — alerts are much more relevant now."
- "Easy to install with PoE and compatible with our existing NVR via ONVIF."
- "Good value for money for perimeter coverage, though for long-range detail we'd pick a telephoto lens or higher-res model."
Note: these are representative, anonymised comments reflecting common user experience patterns. Always review third-party reseller reviews and case studies for site-specific feedback before procurement.
The DS-2CD2T26G2-4I(2.8mm)(D) delivers a balanced combination of image quality, intelligent analytics and outdoor durability at an accessible price point. DarkFighter low-light imaging and Smart IR extend useful imaging into night hours, while AcuSense human/vehicle classification reduces unnecessary alerts and helps security teams respond to meaningful events faster. PoE support, microSD local storage and ONVIF compatibility make it easy to deploy in existing networks and NVR ecosystems.
For perimeter and general exterior surveillance where wide coverage, dependable detection and cost-effectiveness are priorities, this Hikvision AcuSense bullet camera is a strong contender. Prospective buyers should confirm the exact IR/variant (2I vs 4I), verify compliance requirements for their procurement environment, and plan for firmware and security hardening during installation to ensure optimal performance and resilience.
