In order to be able to better identify and track offenders in the stands in the future, the operator of the Alsancak Mustafa Denizli Stadium opted for a video security solution from the German manufacturer Dallmeier.

Up to 15 % fewer spectators due to riots
In Türkiye, stadiums are usually owned by the Ministry of Sport, which then grants the rights of use to an operator. In the case of the Alsancak stadium, the operator is “Altay Izmir”, an Izmir-based football club that currently plays in Türkiye’s top professional league. The club, like so many other football stadiums, has had its fair share of repeated incidents and threats to spectators and players. These have included verbal abuse and even the throwing of objects onto the pitch. In addition to the intangible damage to the image, the consequences have been painful, ranging from traditional fines to the closure of an entire block of spectators – a loss of 1,000 to 2,000 spectators per home game, and that on a regular basis.
Under these conditions, the operators were looking for a solution that would allow them to reliably detect and track potential offenders. The tender specified a minimum resolution density of 144 pixels per metre (px/m), which is also required by law. This means that there must be at least 144 pixels in the camera image to represent every metre of “reality” in the stands. This value is between the “recognition” (125 px/m) and “identification” (250 px/m) qualities specified in the IEC EN 62676-4 standard for video surveillance systems.
Only ten cameras to monitor the stands
To find the most suitable solution for the Alsancak Stadium, the Ministry of Sports decided to invite various manufacturers to a comparative test. After receiving the proofs of concept (PoCs) of several companies, the owner chose a solution from the German manufacturer Dallmeier electronic. In addition to around 140 single-sensor cameras for corridors, outdoor areas and entrances, only ten “Panomera®” multifocal sensor systems are required for the particularly critical grandstand surveillance.

Remote “FAT” and training from Dallmeier Türkiye
Due to the COVID-19 pandemic, the stadium's technicians were unable to travel to Dallmeier's headquarters in Regensburg, Germany, to commission the system and attend classroom training. For this reason, the so-called Dallmeier Factory Acceptance Test (FAT) took place online. The entire system was set up, configured and remotely accepted in the FAT centre in Regensburg. The training of the technicians and operators was carried out by Dallmeier Türkiye experts on site. Serkan Atalar, CEO of RESA Construction Electromechanical Inc. CO, the installer company that implemented the project, is very pleased: “Dallmeier's sincere and collaborative approach, as well as the high-tech products and after sale support they offered were very impressive. We thank Dallmeier Türkiye for the great cooperation.”
“The customer is very satisfied with the Panomera® systems. The benefits are equivalent to combining a powerful megapixel camera with any number of high-resolution 'virtual' PTZ cameras. At the same time, the systems reduce the total cost of ownership for infrastructure, cables, masts, screens, workstations, etc.,” Serkan Atalar summarises. “Alsancak Stadium only needs three system operators with one monitor each. They also have two workstations for the police and management. The solution always gives them 100% control of the security situation in the stadium, allowing them to react immediately and reliably track down perpetrators. And all this at a low total cost of ownership and with minimal manpower thanks to the unique multifocal sensor technology.” (STADIAWORLD, 25.09.2023)
