The surveillance system is primarily intended for road management and maintenance, for traffic intensity monitoring, or monitoring and evaluation of weather, road surface condition, and the current road passability. Publishing the visual information for the public is a by-product of the priority intention of these technologies.

Surveillance cameras located on motorways and expressways are integrated into the Integrated System of Video Information. The visual information is used by the National Traffic Information Centre, Czech Police, Czech Fire Rescue Service, Emergency Rescue Service, road administrators and other users, e.g. media (radio and TV). Static images taken by the cameras are also published on the Internet, at the Czech Traffic Portal (www.dopravniinfo.cz).

The following two types of cameras are used most frequently:

  • fixed cameras, located on permanent stations; these are mostly rotating zooming cameras. These cameras also provide continuous video,

  • mobile cameras that are temporarily placed on road sections with long-term traffic limitations or in localities that are critical in terms of accident rates, traffic queue occurrence, etc. The transmission of static images is done via GPRS approx. every 5 minutes.

Other surveillance systems are gradually being built on motorways and expressways, especially where new roads are built. Certain cameras located on other roads or in other places (e.g. cities) shall gradually be included into the Integrated System of Video Information.
