SECURITY CHALLENGES IN STADIUMS
Stadium events are some of the most crowded community events. If tens of thousands of people gather in one place at the same time, the security risk is constantly high. Dangerous situations such as riots, fights, arson, bottle throwing, property damage, bombings or shootings are prone to happen. Therefore incident prevention and quick reaction are the keys to ensuring the safety of spectators, staff and players. The Logipix Stadium Video Surveillance solution was designed specifically with these challenges in mind.
THE AIM OF THE LOGIPIX STADIUM VIDEO SURVEILLANCE SYSTEM
The aim is to provide a safer environment in stadiums. The system helps prevent the escalation of violent incidents by providing high-definition footage of all seats simultaneously. By using Logipix features, security staff are able to handle incidents quickly, effectively and appropriately. Thanks to the solution they can also provide irrefutable video evidence for authorities.

Face recognition at every seat with panoramic images
Several 20 MP Logipix ONE camera images are stitched together, creating virtual panoramic views to cover the entire stadium with fewer images. The stitching is not visible to the naked eye so faces appear without distortion. The Virtual Panoramas provide 20 FPS and resolutions of hundreds of megapixels, making face recognition possible in even the largest stadiums. Operators can locate sectors much more easily on these large panoramic images and detect any suspicious or dangerous behavior quickly. As every face is clearly visible on the security footage, these can be used as irrefutable evidence for authorities.
The stitching technology
The images of the individual cameras do not simply overlap during the stitching procedure, but are geometrically transformed at the image borders to provide accurate pixel alignment on the stitching lines. The cameras take their images in a synchronized fashion so moving objects are not duplicated at the image borders. The Logipix Control Center allows for white balance correction that smoothens the color gradient between the stitched images. As a result, operators can work with panoramic images containing no hidden or redundant areas, creating the appearance of a single image.
Zoom functions on the panoramic images
Although the Logipix Virtual Panorama consists of several images of individual cameras that are stitched together, operators can work with the Virtual Panoramas as if they constituted single images. The operators can use multiple zoom windows on a monitor profile that are associated with the panoramic image. Using the zoom windows, they can zoom in on any part of the panoramic image to observe the situation in greater detail while still maintaining sight of the whole monitored area, since the panoramic image is still visible. Operators can also move around these zoomed areas and track the movements of suspicious individuals.
More details with the Logipix PTZ
Operators can continuously scan the various sectors of the stadium with the Logipix 6 MP PTZ cameras. They can control the PTZ cameras interactively with a special control function on the associated panoramic image by selecting a target area. Operators can also move the PTZ by using a mouse-controlled joystick emulation or by simple clicking on the image of the PTZ camera. More visual information on an incident means more effective action to manage the situation.
It is widely known that certain sectors of a stadium are more prone to outbreaks of violence. These potential threat areas can be marked and saved as PTZ positions, and a specific function helps accelerate the navigation between these zones.
Storage effective event management
Control Center allows for dual configuration of the cameras in the stadium. One setup can be used during the events and another with lower quality settings for general monitoring after the event is over.
The Logipix Control Center allows for versatile archive search functions. Both archived and live images can be observed in the Video Monitor at the same time. For instance, the cause of an outburst can be investigated on the video monitor via the panoramic image, while the real-time situation can still be observed by the PTZ cameras.
Match Operation Center
The Match Operation Center, the so-called MOC is a centralized monitoring room that is installed when multiple stadiums use the Logipix system across the city or the country. All the stadiums are remotely accessible and fully manageable from the monitoring room.
Covering the entire seating area with fewer, high-resolution images – The Logipix Stadium Video Surveillance solution uses the high-resolution Virtual Panorama to cover every seat in the stadium.
Every faces is recognizable – The Virtual Panorama delivers 200-320 MP images that allow for face recognition at every single seat in the stadium. The additional 6 MP PTZ cameras further extend the available resolution thanks to their optical zoom capabilities.
Flexible camera structures – As the Logipix Virtual Panorama consists of individual cameras, the system can be tailored to various stadiums of any size. The Logipix Stadium Video Surveillance solution can grow with the stadium in case of future developments.
Easy PTZ control – Logipix developed a unique PTZ control function. Operators can use the image of the Virtual Panorama to guide the PTZ simply by selecting the area of interest on the panoramic image.
Fast reaction in case of an incident – In case of any disorderly conduct, the archive recording can be examined frame-by-frame instantly, and the security staff can take the necessary measures immediately.
Fast and reliable recording – The Network Video Recorders of the solution provide recording speed of 7 Gbit/sec, and use a VRM fail-safe file system for storing the images.
Storage effective operation – It is possible to configure the system to operate with high FPS and high resolution during an event, but with moderate settings for the time in between events.
