The video analysis systems represent a major advance over traditional motion detection systems from analog cameras or digital recorders. In recent detection systems depend invaded image area and time regardless of other features.
Professional analysis systems TBK take into account many other factors in generating alarm. Based detection systems video analysis is based primarily on the proportionality of the objects. We can establish a grid on the screen that differentiates perfectly detects the same object depending on whether you are at a distance near or far. Another of the key issues in this type of system is the generation of group elements: people, vehicles, animals, etc … This allows us to classify each element and generate rules to discriminate those elements of groups that do not interest us. The groups also allow us to generate counters and assign those accounts to each of the groups or to realize the counting directly.
One of the fundamental differences with traditional motion detection systems is that video analysis can discriminate unwanted calibration precisely and generating element groups small movements of vegetation, changes in scene brightness or elements. Among the various rules that we can set filters have presence, loitering, directionality, color, counters person arrested objects, multiple access, etc …
This whole system of video analysis is done individually in each element (camera or encoder) and the data can be obtained remotely using statistics or graphs and using metadata. All cameras and encoders have systems for SD card storage and alarm inputs and outputs to produce the required notices and form a system completely standalone video analysis. As we mentioned there are IP cameras that carry them licenses corresponding video analysis or we can use the encoders. These elements allow to use any analog camera on the market and connect these encoders performing the same functions of video analysis but with reduced significantly to save IP camera module costs.
