Product Details

The Hikvision DS-2CD2146G2-ISU is a 4 Megapixel network dome camera with a 2.8mm fixed lens which uses AcuSense to greatly reduce the number of false alarm notifications received, and produces high quality colour images in ultra low light scenes thanks to Hikvision's Powered by DarkFighter Low Light Technology. It also features a built-in microphone and speaker for real-time 2 way audio security, and an optional interface to add an external speaker.

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

Alongside the AcuSense deep learning capabilities, the DS-2CD2146G2-ISU is complimented by Hikvisions 'Powered by Darkfighter' technology. This allows the camera to stay in colour mode for longer in low light conditions. When small details matter, such as the colour of an intruders clothes, Darkfighter allows for more detailed surveillance for longer periods.

H2.65+ Compression

Hikvision lifts video surveillance to an unprecedented level with its H.265+ codec. In Full HD mode, H.265+ uses less than 20% of the bandwidth of H.264, allowing for live streams of unrivalled quality.

H.265+ also greatly outperforms all its predecessors in terms of storage. Regardless of environment or application, H.265+ reduces the required storage space by more than 80%. In short, H.265+ allows you to kill two birds with one stone: you can now record images at amazingly high resolutions and minimise the required storage capacity. This makes H.265+ the ideal solution for 24-hour surveillance.

Features:

  • High quality imaging with 4 MP resolution
  • Excellent low-light performance with powered-by-DarkFighter technology
  • Efficient H.265+ compression technology
  • Clear imaging against strong back light due to 120 dB true WDR technology
  • False alarm reduction through human and vehicle target classification based on deep learning
  • Water and dust resistant (IP67) and vandal-resistant (IK10)
  • Built-in microphone for real-time auto security
  • 3D DNR technology delivers clean and sharp images
  • 2.8mm fixed lens
  • Up to 30m IR distance
  • Face Capture
  • Smart motion detection
  • Supports on board storage (up to 256GB)
  • 12V DC & PoE (802.3af)

  Can this be mounted on a vertical walls?  ( )
  Yes this can be mounted vertically as it has a 3 axis internal gimbal. We recommend avoiding this when installing dome cameras externally as they can be hindered by rain running down the dome and impacting the image.  ( )
