It is also important to reduce the total cost of ownership of the video surveillance system. As you know, you can save in two ways: buy the cheapest equipment or reduce the total cost of ownership of the system. Axis suggests following the second path, using Zipstream technology. According to Alexey Mayorov, it is built into the cameras, automatically adjusts to the picture, determining the number of moving objects and the zones in which the objects are moving, and accordingly changes the frequency of the reference frames, and also reduces or increases the frequency of the frames themselves. This makes it possible to dynamically reduce the bitrate depending on the picture, which in turn allows you to save up to 50% of the archive volume. "It is known that one of the most expensive parts of video surveillance systems is the data storage system. Often, its cost exceeds the cost of all video surveillance cameras," said Alexey Mayorov.
According to him, are implemented in the P13 series greece mobile database cameras. This line includes nine models, four of which are manufactured in Tver at the Jabil plant, one of Axis's contract manufacturers.
Alexey Mayorov explained that certification began with the P13 because it is one of the best-selling Axis cameras and one of the most popular in the transport segment. This is indicated by the fact that the P13 series is used in most of the projects presented by Mark Pavlitsa.
Thus, in the St. Petersburg metro, more than 3,200 P1365 cameras have been installed at 28 stations, which serve to monitor the current situation and investigate incidents, automated detection of lost items and video analytics in conditions of dense passenger flow. It is planned that another 8-10 stations will be equipped this year.
The Moscow Metro has an automated control system for detecting radiation and hazardous substances based on 523 P3384 cameras. As Mark Pavlitsa explained, when a person with a hazardous substance passes through the frame, an alarm sounds and the camera starts recording, this data is sent to the monitoring center and used to find violators.
