Intelligent optical radar- Seaport of the SEIF Palace

The monitoring of wide open spaces such as desert borders or seashores is a difficult and expensive task. However, there is a need to detect intruders from a long distance which for a pedestrian could be as far as one to one and half kilometer, and for a motorized vehicle this distance could be three to five kilometers. Because this monitoring takes place day and night the problem of lighting is crucial and no active system can be used at these dis-tances. Therefore, thermal cameras are the only realistic and practical solution.
The problem with thermal cameras besides their lack of details on the targets is that in order to achieve the distances mentioned above we need to use long-focal lenses, resulting in a very narrow field of view. This in turn implies that a large number of cameras have to be installed to cover wide-open spaces and thermal cameras are quite expensive.

 

Mission 

 

ACIC and its partner Comtec Systems have joined forces to develop and install a very reliable and profitable solution: PanoramaDetection®. The mission of this solution is to monitor a large coastal area with specific PTZ type cameras. To our knowledge, this is a «world first». The solution has been successfully installed by Comtec Systems in several projects in Kuwait.

 

Solution 

In short, the solution called PanoramaDetection® consists of installing a thermal camera with the appropriate lenses capable of coping with difficult conditions. In summer for example, when the thermal contrast between a human body and the surrounding marine mass or the ground is very low. This thermal camera is installed on a latest generation PTZ head and constantly scans the area to be protected. The ACIC PanoramaDetection video analysis tool creates a digital panorama when the camera is scanned. This panoramic image is updated with each scan. When a target is detected in the area to be monitored, an alarm is signaled. In addition, the application interrupts scanning and moves the camera to keep the target in the field of view. After a while, scanning resumes to continue monitoring the area.

 

Results

The whole solution is in operation since 2013 in very harsh climatic conditions and has thus far performed to full satisfaction. These intelligent sweeping thermal cameras can be compared to an optical radar but in reality is far more efficient than a radar. Radar always requires additional camera (s) to verify the alarm and identify the threat, which result in high investment and maintenance costs. ACIC-Comtec Systems solution is simpler, less prone to interferences and much less expensive.
