Stack Camera

Hikvision DS-2DE4225IW-DE(T5) 2MP 25× Network IR Speed Dome adopts 1/2.8" progressive scan CMOS chip. With the 25× optical zoom lens, the camera offers more details over expansive areas. This series of cameras can be widely used for wide ranges of high-definition, such as the rivers, roads, railways, airports, squares, parks, scenic spots, and venues, etc. Empowered by deep learning algorithms, Hikvision AcuSense technology brings human and vehicle targets classification alarms to front- and back-end devices. The system focuses on human and vehicle targets, vastly improving alarm efficiency and effectiveness.

  • Focuses on human and vehicle targets classification based on deep learning
  • Support face capture. Up to 5 faces captured at the same time
  • 1/2.8" progressive scan CMOS
  • High quality imaging with 2 MP resolution
  • Excellent low-light performance with powered-by-DarkFighter technology
  • 25× optical zoom and 16× digital zoom provide close up views over expansive areas
  • Expansive night view with up to 100 m IR distance
  • Support H.265+/H.265 video compression

DORI

The DORI (detect, observe, recognize, identify) distance gives the general idea of the camera ability to distinguish persons or objects within its field of view. It is calculated based on the camera sensor specification and the criteria given by EN 62676-4: 2015.
