Some 14 of the 20 clubs in the 2019–20 English Premier League season have Dallmeier Panomera multi-focal sensors in use – including such names as Everton, Arsenal, Chelsea, Liverpool and Manchester United.
As several teams in the top flight of English football play in the Champions League and Europa League, they need to satisfy the safety regulations imposed internationally by UEFA and similar bodies. Dallmeier says that its product enables high-resolution capture of expansive areas, such as the stands, with a minimum number of cameras. With the Panomera, multiple operators can zoom in independently of each other, while the system continues recording the entire scene. With this combination of PTZ and megapixel cameras, an optimum overview of the situation is obtained, which can also be searched in the required minimum resolution afterwards. This enables the clubs to achieve continuity of video evidence, and get ID of people and events.
Besides the usability of video recordings, the “minimum resolution density” is also important for video analysis. As according to the rule “quality in, quality out”, the quality of the results of analysis – for example in “crowd analyses” for people counting on stands, for “hostile vehicle mitigation” or to detect intrusion in sterile areas – can only ever be as good as the quality of the image, and accordingly the quality of the input data. Dallmeier says that at the planning stage customers can specify the pixel density values defined according to DIN EN 62676-4 for each region of the area captured – depending on whether for example at least 62.5 px/m is required for AI-based object classification, or 125 or even 250 px/m is required to guarantee that recordings of persons will be usable in court.
Everton’s ground Goodison Park, pictured, has used the Panomera since 2013. David Lewis, Head of Security and Stadium Safety for Everton FC says: “Throughout our selection procedure, the Panomera cameras from Dallmeier were able to deliver images of the highest quality time after time, not only in normal daylight conditions, but also under weaker floodlighting, that is to say not only live but also in the recording with the highest resolution quality in all regions of the images. Moreover, with the Panomera cameras we can capture large expanses, the entire area of the stands, for example, with just a small number of systems. Ultimately, these considerations were the critical factor in our decision to award Dallmeier the contract for video security at Goodison Park.”
