Video-recording and video-analytics for motorway traffic monitoring

AiVu-HDVR-tunnel is a full management solution handling video-footage from IP-cameras, analogue cameras and video servers.

AiVu-HDVR-tunnel brings all in-tunnel traffic-management functionalities together onto one device. Features include accessing live from cameras set along routes, acquiring and displaying of recordings, video-analytics for real-time detection of danger and smoke.

Intel-based SW architecture manages up to 64 IP/analogue inputs, runs on 2.0 ONVIF-compliant cameras and can also support PAL/NTSC-based CCTV- systems.

The streaming of videos supports different types of compression standards such as MJPEG, H.263, MPEG-2, MPEG-4, H.264 and WebM. The bitrate of output adapts dynamically to the available bandwidth, in order to provide optimal access to the images on the LAN, WAN, GSM / GPRS, 3G and 4G.

Multiple users can access simultaneous to the live streams and recordings, setting the parameters for the transmission of images to suit their needs: the “transcoding” feature allows to capture and store high-resolution images locally, and recoding them on-the-fly with different parameters of resolution, frame rate and codec.

Features

  • Acquisition of HD and analogue PAL video stream
  • IP-streaming of live and recordings
  • Sw modules for video-analytics (AID – Automatic Incident Detection)
  • Automatic smoke detection (inside tunnels)
  • User-friendly web-interface for video search and display functions
  • Diagnostic tools
  • Easily integrated into other IT infrastructures
  • Streaming to “mobile” devices
  • RMT-compliant (Road Management Tools)

The hardware: AiVu-HDVR Rack

AiVu-HDVR-tunnel requires a 4U 19″ Rackmount Chassis for industrial purposes. Strength and resistance to a wide range of temperatures imply that AiVu-HDVR Rack is highly reliable and suited to difficult operative conditions inside technical rooms.

  • Manages up to 64 video-streams
  • Power-supply (2 x 350W 110-220Vac)
  • Removable Hard Disk
  • Depth: 450 mm (approx)
  • Weight: 20 kg
  • Temperature range: -10°C / 60°C

Video Analytics

AiVu-HDVR-tunnel integrates modules for video-analytics: image-processing algorithms perform motion detection analysis based on background-image variation. Security infringements are signaled by automatically generated alarms. A user-friendly interface allows for the drawing of virtual sensors on any frameshot. Detected events:

  • Detection of stationary vehicles on carriageways
  • Detection of people on carriageways
  • Detection of queues and tailbacks
  • Detection of accidents
  • Detecting wrong way vehicles
  • Vehicles counting and classifications

Smoke and fire detection

AiVu-Smoke&Fire is Aitek’s sw module for the automatic detection of  smoke, fire and fog (including low-grade incidents). An easy-to-set algorithm and highly reliable image-processing make for prompt alarm signal generation.
