What kind of situation center do you need?
Determine the dimensions
First of all, you must clearly decide what processes will be monitored, analyzed and decided upon. To estimate the number of information sources (city services, surveillance cameras, etc.) that will transmit data to the center, and based on this you can calculate the number of controllers and operators who will be needed to process the data, and therefore the size of the center itself.
Determine the necessary equipment
After the size of the center and the number of operators is clear, it is necessary to see the data from what sources of information to receive: data from cameras, television channels, the location of emergency vehicles, telephone calls, maps of the city or industrial facilities, etc. Based on that, it will be possible to decide what kind of equipment the center will need.
Building a new center or modernizing an old one
In the last step, once you have decided on your goals and means, you need to decide how to use the situation center space to house dispatchers and equipment systems. Your budget will also play an important role, as well as whether you are building the situation center from scratch or whether you need to upgrade it.

Situation center equipment systems
The complex of situational center equipment systems includes the following main subsystems:
- Display subsystem
- Switching subsystem
- Voice subsystem
- Control subsystem
- Communication facilities
- Fixing elements
Display subsystem
The information display subsystem is designed to display video content (text files, graphics, video information).
Video Wall as the main means of video displaying
A video wall is a screen for collective display of information in the situational center. It displays the main stream of data coming into the situational center.
When selecting a solution for the video wall a number of factors shall be taken into account
On the basis of this information, the system integrator who is to install or upgrade the situational center equipment shall develop technical solutions for the video wall:
Video Wall as the main means of video displaying
A video wall is a screen for collective display of information in the situational center. It displays the main stream of data coming into the situational center.

- Ability to play streaming video from the Internet (IPTV, HTTP video streaming).
- Ability to manage content playlist.
- Providing synchronization with time servers.
- Possibility to set intervals of triggering events, setup of repeating by periods (by days of week, certain months, etc.).
- Possibility of controlling and collecting statistics on the hall usage and storing the equipment settings in the database.
- Ability to upload statistical data to XML, CSV. Translated with www.DeepL.com/Translator (free version)
Video display system based on a video wall controller
The display system is based on a video wall controller. Video wall panels are connected to the processor outputs to create a single display system.
The desktop of any operator's computer can be broadcast to one of the video wall panels or to the whole wall via VNC technology, i.e. one of two modes can be selected:
The desktop of any operator's computer can be broadcast to one of the video wall panels or to the whole wall via VNC technology, i.e. one of two modes can be selected:
- In the first mode, the desktops from the dispatchers' computers are simultaneously broadcast, each on its own panel.
- The second mode allows you to select and display one of the desktops on the entire video wall. The mode and the displayed desktop is determined by the operator, who performs control from his computer.
Means of communication
It is also necessary to determine what types of communication will be used in the Situation Center:
- Telephony (POTS) IP-telephony (VoIP, ATM, ISDN, etc.)
- radio communications
- satellite communication
- interactive video conferencing
