The best video analysis can only be as good as considering all the related parameters. This is important not only for solar parks but also for every other outdoor protection with this kind of security system. Sometimes there are false alarms even without subjective, alarm triggering events. This raises the question about the reason for the alarm.
If all the software parameters have been perfectly set and specific image weaknesses (e.g. reflection) considered, or bushes cleared away, many times it´s the camera holder and pole that trigger false alarms. What does the video analysis software “see”? In principle, the software interprets pixel movements. You can see that very well in the video clip. The image on the upper left shows the actual “view” of the analysing software.
Pixel changes emerge from movements in front of the camera but also from the movements of the camera itself. For the video analysis the reason for the pixel changes is totally irrelevant. Only the relation between fixed and moving matters. It means that a perfectly calm scenery can turn into a moving image through a moving camera.
In case of strong gusts and constant wind, it is possible that the camera sways or vibrates slightly via the camera holder and pole, therefore resulting in uncontrolled pixilation noise. You can see this also very well in the video clip.
For that reason, the selection of the camera pole and the camera holder is of decisive importance. It is essential to consider the appropriate pole with the required height of 4,5 m, demanded by the video analysis, as well as the necessary stiffness. Otherwise, the video analysis, an excellent instrument can become very annoying.
