Video surveillance at the stadium.
The football topic suddenly became one of the most pressing, in connection with Russia's victory in the vote to determine the host country of the 2018 World Cup.
Considering the scale of the event, security came to the fore.
Russia planned to host not only world-famous athletes, but millions of tourists from all over the world.
Responsibility for their safety fell on the shoulders of the host state. It was necessary to think about ensuring security during the match on the stadium grounds.
It was necessary to provide protection for spectators and athletes from riotous fans and offenders, to prevent ticketless entry to events, to control items carried in, to ensure the safety of the building's material property and visitors.
Video surveillance was supposed to facilitate early detection of illegal actions and coordination of security forces during the suppression of riots.
This is the main task of video surveillance systems.
A secondary but no less important task is to provide video evidence for subsequent legal proceedings.
This factor often justifies all investments in a video surveillance system, because the club whose fans are guilty of the incident will have to pay for the damage.
In order to ensure the fulfillment of all these tasks, it is necessary to competently design a video surveillance system.
Almost the only solution for monitoring the stands is to install a number of controlled high-speed dome cameras in each sector.
Similarly, it is necessary to monitor the extended areas adjacent to the stadium.
The Acumen Ai-SD99W high-speed IP camera with a wide dynamic range functions perfectly in various temperature conditions from -55 to +55 degrees Celsius, so it can be used in any Russian latitudes.
The camera's vandal-proof properties allow you not to worry about its safety from the aggression of offenders.
When a suspicious situation arises, the operator manually points the nearest dome camera at the dangerous area and, by controlling it, finds key moments, gives guiding recommendations to security personnel and the police.
Cameras should be installed primarily in such a way as to obtain frontal filming of spectators.
Those sitting in the front rows should not block those sitting behind. Only if all these conditions are met can the facility be considered suitable for ensuring security.
It is necessary to carry out control visually, against the background of raging fans even an operator will have problems detecting danger, not to mention computer systems.
Video surveillance system operators are required to monitor each of the cameras in real time.
The video stream from the cameras is sent to the operator's monitor, and in the event of a violation of public order, it must be possible to control the corresponding camera remotely.
Therefore, there should be many operators so that each sector is covered as fully as possible. Additional operators can be brought in for the duration of the match.
Workstations should be provided for them, and each operator should be trained in advance.
In addition to controlled cameras, fixed cameras providing an overview image are required.
For example, a color all-weather vandal-proof high-resolution varifocal camera with a long range of IR illumination Ai-IR97N.
It is on them, constantly displayed on overview monitors, that operators must detect the first signs of an incident.
It is they who provide constant coverage of all areas, even if operators have switched their attention to individual areas.
All information received from surveillance cameras will be recorded on a video recorder. The 16-channel Acumen Ai-D167S recorder is ideal for solving the problem of ensuring security at the stadium.
Video recorder Ai-D167Ssupports the ability to connect up to 4 SATA 3.5 hard drives of unlimited capacity to ensure continuous recording for a long time in the highest quality.
The recorder has a failure detector and an alarm sensor that will notify you when the hard drive is full.
In the event of an incident, the necessary video information can be easily found thanks to a smart search: by date, time, alarm signal, signal loss.
Video recording of the event must be saved for a week, this is established by law.
Also, the law requires:
- use of backup power supply for all installed devices in case of power outage.
- The presence of central control equipment installed in a special room for full control of video material coming from internal surveillance cameras, in order to ensure continuous monitoring and timely response to emergency situations. This room can be quite spacious to accommodate (in addition to control devices) technical personnel of the security control center of the sports event.
The task of monitoring the behavior of fans has some features, and some significantly simplify this task.
For example, voluntary bright coloring of potential violators of order.
A designer's dream.
If only terrorists were dressed as brightly and contrastingly as fans at a football stadium.
However, the consequence of such a feature is the mandatory color video surveillance system, otherwise such a rare fortunate circumstance will be lost.
On a black and white monitor, it will be quite difficult to distinguish red and white jerseys from yellow and blue ones.
The second positive circumstance is good lighting in the stadium as a whole, and therefore in the stands.
There are some problems with possible backlighting from powerful floodlights, but they are easy enough to avoid by carefully choosing the location of the cameras.
It is necessary to take into account that in conditions of fog, the use of smoke bombs or similar means (which is not at all surprising in the case of riots) the light from the floodlights is strongly scattered, so the cameras must be aimed with a fair margin in angle from the backlight.
In case of emergency, many stadiums have special floodlights directed at the stands — check the operation of the system when they are turned on.
The consequence of the need to take into account possible illumination is that, despite the theoretical possibility of rotating cameras in all directions, in reality they should only be used to monitor those sectors for which they are intended.
Stadiums are considered the most complex and dangerous security facilities.
And it is impossible to get by with video surveillance alone in this case.
Human control is also necessary. The main objective of video surveillance during a football match is the fastest and earliest possible detection of actions that are contrary to the law.
At the same time, if illegal actions are detected, an immediate response from security forces is required.
As practice shows, surveillance is simply necessary during a football match, since the clarification of relations often ends up in court, and this is why it is so important to provide documentary evidence of what happened.
