More Information


The Hikvision DS-2DE4A225IWG-E is a 2 Megapixel speed dome PTZ camera with 25 x optical zoom, 16 x digital zoom and infrared distance of up to 50 metres. Intelligent Acusense technology greatly reduces the number of false alerts received and high-quality colour images in ultra-low light scenes are achieved thanks to Hikvision's Powered by DarkFighter Low Light Technology. 

Auto tracking allows the camera to automatically follow movement in the scene. Not only does this provide a strong deterrent by giving the impression the camera is being manually operated it also provides close up detail of people and objects that may otherwise have been missed.

Deep Learning with AcuSense Technology


The most common concerns in perimeter protection are trespassing and vehicle break-ins. AcuSense helps you to focus on these events in two ways

  • Alarm will only trigger when the preset intrusion type takes place
  • Related videos are sorted by categories for easier search

Users can focus on alarms triggered by humans and vehicles while false alarms triggered by small animals or other irrelevant objects are vastly reduced



  • High quality imaging with 2 MP resolution, up to 60 fps
  • Excellent low-light performance via Powered-by-DarkFighter technology
  • Clear imaging against strong back lighting due to 120 dB WDR technology
  • Pan and tilt ability enables camera to monitor zones of interest
  • 25 × optical zoom allows for closer viewing of subjects in expansive areas
  • Up to 50 m IR range ensures safety at night
  • Water and dust resistant (IP66)
  • Focuses on human and vehicle targets classification based on deep learning
