Detailed specifications and benefits
The DS-2CD3686G2T-IZSY blends high-resolution optics, advanced imaging processing and on-camera intelligence to offer benefits across image quality, analytics performance, storage flexibility and environmental robustness.
- Sensor & resolution:1/1.8" progressive scan CMOS delivering 3840 × 2160 (8 MP) — more pixels mean better forensic detail for license plates, facial features and scene context.
- Lens:Motorised varifocal 2.7–13.5 mm (F1.6) — allows remote adjustment of angle of view and zoom without replacing lenses. Horizontal FOV ranges approximately 108° at wide to 46° at tele.
- Low‑light:DarkFighter technology and IR illumination up to 60 m provide usable colour or monochrome images in dim or no‑light conditions.
- Image enhancement:120 dB true WDR, 3D DNR, BLC/HLC and defog help produce usable images in high contrast, noisy or adverse weather scenarios.
- AcuSense deep‑learning:Human and vehicle classification helps reduce false alarms caused by windblown vegetation, small animals or lighting changes. Perimeter protection and people counting add operational value for both security and business intelligence.
- HEOP platform:1.5 TOPS compute with 2 GB eMMC allows third‑party apps and advanced processing to run on the camera, enabling flexible deployments and edge analytics.
- Compression:H.265/H.264 (including H.265+/H.264+ variants) reduces bandwidth and storage costs while maintaining image quality.
- Storage:On‑board microSD support up to 512 GB for edge recording and redundancy.
- Network:10/100 Mbps RJ45 with ONVIF Profile S/G/T and IPv4/IPv6 support for interoperability with VMS/NVR solutions.
- Power:PoE (IEEE 802.3at, Class 4) or 12 VDC — PoE simplifies cabling and installation in many deployments.
- I/O & audio:Audio in/out and 3 alarm inputs/outputs enable integration with external sensors, alarms and audio systems.
- Environmental:Rated −30 °C to 60 °C operation, IP67 ingress protection and IK10 vandal resistance for reliable outdoor use.
Use cases and scenarios where the camera excels
The DS-2CD3686G2T-IZSY is particularly suited to projects where both broad area coverage and analytic accuracy are required. Typical scenarios include:
- Perimeter security:For industrial sites, warehouses and logistics yards, the combination of varifocal optics and AcuSense analytics gives wide coverage and reliable detection of intruders while cutting false alarms from animals or debris.
- Car parks and vehicle areas:Vehicle classification and high-resolution 4K imaging help with incident investigations, vehicle identification and perimeter intrusion detection across large lots.
- Building façades and entrances:Face capture and people counting enable access monitoring and visitor analytics while the varifocal lens lets you fine-tune framing to capture entrance flows.
- Retail perimeters and plazas:People counting and analytics support loss prevention, crowd management and operational insights for busy retail externals or open-area public spaces.
- Transport hubs:Stations and terminals benefit from robust low-light performance and perimeter protection for both safety and security operations.
Beyond these, the camera is a solid choice wherever you need a rugged outdoor device that balances image detail, analytics and installation flexibility.
Comparisons with similar products in the market
When evaluating the DS-2CD3686G2T-IZSY, it helps to weigh its strengths relative to both fixed-lens 4K cameras and competing varifocal models from other major manufacturers.
- Fixed‑lens 8 MP cameras are often less expensive and simpler to configure, but they lack the flexibility to remotely adjust field of view. The motorised 2.7–13.5 mm lens on the Hikvision model means installers can fine-tune framing after installation, reducing the need for rework.
- Varifocal capability also allows one model to cover multiple scene types (wide overview vs. mid-range detail) which can reduce SKU count on projects.
- Many competitors offer 4K varifocal bodies; the DS-2CD3686G2T-IZSY distinguishes itself with Hikvision’s AcuSense deep‑learning suite and HEOP platform. AcuSense’s human/vehicle classification is widely used to cut false alarms — a practical advantage for monitored sites.
- IR range, low-light performance and rugged ratings are comparable to other enterprise-grade outdoor bullets. Price and software ecosystem (VMS compatibility, third‑party app support) are other deciding factors — Hikvision’s broad ecosystem may simplify integration for existing Hikvision-based systems.
In short, if your priority is flexible framing, on-camera deep‑learning analytics and integration into a Hikvision-centric environment, the DS-2CD3686G2T-IZSY is a compelling option. If you need tighter vendor neutrality or specific third‑party certifications, compare ONVIF support and HEOP application compatibility with the alternatives you consider.
Customer feedback and reviews (representative observations)
Publicly available reviews and installer feedback for cameras in this category commonly highlight a few consistent points. The following represent typical, anonymised observations reported by installers and security managers using comparable Hikvision AcuSense cameras:
- Positive:Installers appreciate the motorised zoom for quick on-site setup and the PoE option to reduce cabling. Security teams often report a reduction in nuisance alerts after enabling human/vehicle classification, saving monitoring time and storage.
- Performance:Many users note clear improvement in identification and analytics versus older non-AI cameras, especially in day/night transitions thanks to DarkFighter and IR support.
- Considerations:As with any feature-rich camera, correct configuration (sensitivity, detection zones, firmware updates) is important to maximise analytics accuracy. Professional installation and periodic firmware maintenance are recommended.
Note: These statements are representative of typical feedback for this class of camera and are intended to convey what users generally report rather than specific endorsements.
