92 | SPORTS VENUES 2023/24 www.stadiaworld.com TECHNOLOGY The Alsancak Mustafa DenizIi Stadium in Izmir – named after former Turkish football player and current football coach Mustafa Denizli – is a multipurpose stadium that mainly hosts football matches. With over 15,000 seats, it is one of the medium-sized stadiums in Türkiye. Originally built in 1929, it was demolished in 2015 and reopened after reconstruction in November 2021. 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. The low number of camera systems required for grandstand surveillance is due to the patented multifocal senCamera technology for Turkish Stadium 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.
