Full Technical Description
The Hikvision HiWatch HWI-B121H(C) provides clear Full HD video for homes, shops, offices, warehouses, and small commercial surveillance systems. Its 2MP progressive-scan CMOS sensor captures images at 1920 × 1080 resolution, while the 2.8mm wide-angle lens covers a broad monitoring area.
Key Features
- 2MP Full HD resolution: 1920 × 1080 video at up to 25/30 fps, depending on the video setting.
- 2.8mm fixed lens: Wide-angle coverage for entrances, corridors, shops, and outdoor areas.
- Infrared night vision: Smart IR illumination up to 20 metres according to the manufacturer's datasheet.
- H.265+ compression: Reduces bandwidth and storage requirements.
- PoE support: Simplifies installation with a single network cable for power and data.
- Digital WDR: Helps balance scenes with different lighting levels.
- 3D DNR: Reduces image noise, particularly in low-light conditions.
- Motion detection: Supports motion events and exception notifications.
- IP67 protection: Designed to resist dust and water for outdoor installation.
- Remote monitoring: Supports compatible Hikvision software and network protocols.
The camera is suitable for installations requiring affordable IP surveillance, remote viewing, and straightforward integration with a compatible network video recorder (NVR).
