Detection on PTZ cameras

Video Surveillance and Pan-Tilt-Zoom Cameras

Safety and Security of transportation infrastructures rely heavily on the use of CCTV - and particularly Pan-Tilt-Zoom (PTZ)- cameras. But as expansion of CCTV camera use in the field of traffic and roadway monitoring continues, CCTV systems are beginning to meet with limitations: too many cameras, too many monitors, TMC not manned 24/7...

In other words, most of the information provided by CCTV cameras is under-used or not used at all because Traffic Operators are not aware of it in real-time.

However, time is of the essence when detecting and responding to an incident in order to prevent secondary accidents and congestions. This is the reason why Traffic Management Centers have turned to Advanced Video Surveillance solutions to assist Traffic Operators to efficiently monitor traffic and quickly respond to incidents.

Why Advanced Video Surveillance is a key tool for to highway Safety? Advanced Video Surveillance provides Traffic Operators with alarms (audible and/or visual) immediately after an incident occurs (within seconds), even before the consequences of this incident can be noticed by a traditional surveillance system. It enables users to be warned in good time and reduces the risk of multiple accidents and congestions. Because it requires not setup or calibration, Advanced Video Surveillance fits perfectly into any CCTV system: no need for additional or new cameras, no need to use preset positions.
How does an Advanced Video Surveillance system work? Existing video signals from the CCTV system (analog or digitally encoded) are fed into a Video Detection Unit. The Video Detection Unit runs a Detection Algorithm. This algorithm is based on tracking techniques and trajectory analysis and detects stopped vehicles within the field of view of the camera. It is a self-learning algorithm that does not require any setup or configuration: it automatically learns the traffic. All Video Detection Units are linked to a Supervisor that receives and dispatches the alarms to Workstations and/or ATMS / SCADA systems. Operators are then, instantly provided with the location of the incident, its type, the live video image and the recording of the seconds preceding the incident.
Can it be installed at any Traffic Management Center? Citilog Advanced Video Surveillance solutions have been designed to fit into an existing CCTV architecture, be it an analog transmission or an IP encoded CCTV network. Video Detection Units are located wherever the video signals are available (in the field, in a hub or at the Traffic Control Centre). The systems architecture is flexible and Citilog offers a wide range of communications solutions. Citilog extensive experience in Highway Management, Security and Safety has already led us to successfully apply our solutions to Expressways, Highways and Bridges. Based on this field experience Citilog has developed specific algorithms to control camera vibrations, thus ensuring more reliable and accurate detection on Highways or Bridges cameras often shaken by high winds. All these elements combined together allow for a fast and efficient response to incidents.
Why is Citilog recognized as the World Leader for Advanced Video Surveillance? From its earliest development 20 year ago to its most recent enhancements, Citilog Video Image Processing algorithms have been focused on incident detection and the transportation industry. Citilog is the only system that has a self-learning algorithm able to report accurately and reliably incidents and that can be easily integrated in any CCTV system. Citilog is recognised as the leader in Video Incident Detection because our systems present Traffic Operators information that they can rely on. Our Advanced Video Surveillance Systems are field-proven and have been successfully deployed worldwide to enhance Safety and Security on various types of road infrastructures: Highways, Expressways, Bridges and Tunnels.
