Over the past couple of years, the need for various security systems, video surveillance and access control has greatly increased in the IT market. There is a mass of solutions, both ready-made and as platforms for creating specialized systems. Any specialist in the adjacent field will be able to select a server for video surveillance, taking into account the parameters and the number of cameras, the nature and dynamics of the object of observation, the requirements for the depth of the archive. But, since, a regular user / customer is not obliged to independently multiply Bitrates and add Gigabytes with Gigahertz, I, due to my duty, have to do it for them, selecting the optimal server configuration. I, as an employee of
STSS , a domestic server equipment assembler and integrator, together with the engineers of the company, developed the
STSS Flagman VX surveillance server line. A feature of these models is the configurator, which allows assembling the system not according to the components, but according to the requirements given by the characteristics of the cameras and the depth of the archive. Thus, the user can select the optimal server model, knowing only the number of cameras, their resolution, frame rate per second and the required archive storage time. Computing and disk subsystem is formed automatically, and meets the specified requirements.
When choosing a server for video surveillance, it is important to consider whether the server will work only for capturing and recording, or will participate in displaying the captured image, along with remote operator workplaces (URM). With a single display of all captured threads, the load on the server increases by an order of magnitude. In most cases, this depends on the features of the software, but, in any case, the load on the server's computing subsystem when unpacking the codec increases many times. The company ITV has a handy
calculator that allows you to assess the difference between systems with and without display.
It is also very important to take into account the dynamics of the scene, since the bitrate is mostly variable, and depends on how often the objects are updated in the shooting area. This affects both the computational subsystem and the volume of the archive.
STSS Flagman VX servers can be supplied both as a platform and as a turnkey solution, including professional ITV Axxon Next or Milestone video surveillance software, POE-enabled switches and IP cameras with various characteristics. Axxon Next and Milestone have the possibility of free use for educational purposes, but with a number of restrictions.
For users with a limited budget, the BestDVR line of
video recorders is presented, which works with both analog and IP cameras. Solutions also include switches and cameras in various designs.
