Panomera® watches over trains as marshalling yards in South Africa are equipped with multifocal sensor technology
 
Trains of the South African public transport operator PRASA are serviced and prepared for their next deployment at the marshalling yards in Braamfontein and Wolmerton. To enable the best possible surveillance of the expansive grounds, which are sometimes partly hidden from view as well, the multifocal sensor technology Panomera® by Dallmeier is being used.
 
The trains of the public transport operator PRASA (Passenger Rail Agency of South Africa) travel long distances every day, bringing thousands of commuters to their places of work and back again. Afterwards, the trains are washed, serviced and parked overnight at the marshalling yards and switchyards. 
 
Combatting theft and vandalism
For most of the trains, night-time is not really quiet, for acts of vandalism are frequent: Trains are wilfully damaged or sprayed with graffiti. Theft is also a serious problem, as Mathew Smith, Senior Technical Engineer at SIYANGENA, who planned and installed the new video system together with Dallmeier, explains: "The thieves are really brazen and even remove seats from the trains."
 
In the past, these problems could not be solved with conventional video technology. "The areas to be monitored are huge, and we cannot set up masts there for the cameras. There are only a very few points at which cameras can be installed – and for conventional HD or megapixel cameras the areas are far too large for us to be able to obtain suitable recordings," says Mathew Smith.
 
PRASA found the solution in the multifocal sensor technology Panomera® by Dallmeier. Contrary to conventional cameras, Panomera® uses several lenses with different focal distances. This makes it possible to monitor a huge surface from only one installation point – and this with the highest detail resolution even in the more distant areas. "With this new sensor concept more distant objects and persons can be shown with the same resolution as objects in the foreground,” explains EP Smit, Sales Manager for South Africa at Dallmeier and co-responsible person for the project planning at PRASA. The fact that this new technology has already been patented is proof of its uniqueness. 
 
 
Keeping an eye on over 750,000 square metres
"Depending on the field of use, there are different Panomera® models that we then adapt individually to the customer's requirements,” adds EP Smit. 
 
For the persons responsible for security a comprehensive view of the entire facility was important. Therefore, four Panomera® systems, each supplying a 90° angle of vision, were cascaded to enable a panoramic view of 360°. In Braamfontein, this makes it possible to monitor a gigantic area of 
400,000 m² and in Wolmerton over 354,000 m², in each case from only one installation point!
 
To make it possible to adequately monitor also areas that are hidden from view between trains, so-called "long-distance” Panomera® models are used. These cameras can cover the long distances between trains, sometimes up to 200 metres, with the highest resolution.
 
Chris Metelerkamp, Project Director at SIYANGENA, is satisfied: "In this way, not only do we have high-resolution and court-admissible video material available to us with which we shall be able to identify offenders from now on. The new cameras are also very helpful for health & safety measures. Now we always know what is happening on the grounds and between the trains.”
 
 
Intuitive operation
The video system is operated through the Panomera® viewer and with the management system SeMSy®. "A great advantage of the Panomera® is that any number of operators can work with the system simultaneously," explains Mathew Smith. For contrary to PTZ cameras, which can only be operated by one person at a time and then only that specific area is recorded, Panomera® continuously records the total image. "Each operator can navigate and zoom freely within the image fully independently of the other operators, regardless of whether in live or playback mode,” says Smith.
 
Overall satisfaction
"We have now been working with Dallmeier and PRASA for quite some time; all PRASA commuter railway stations are also equipped with Dallmeier technology,” Mathew Smith says contentedly. And he adds: "The performance capacity of the Panomera® systems is simply unbelievable." 
 
Dallmeier has at its disposal more than 30 years of experience in transmission, recording as well as picture processing technology and is an outstanding pioneer of CCTV/IP solutions worldwide. This profound knowledge is used in the development of intelligent software and high quality recorder and camera technologies enabling Dallmeier to not only offer stand-alone systems, but complete network solutions up to large-scale projects with perfectly integrated components. Right from the beginning the company always focused on own innovative developments and highest quality and reliability. Dallmeier is the only manufacturer in Germany that develops and manufactures all components on its own. This includes the entire product range, from cameras to picture storage and transmission to intelligent video analysis and even individually adjusted management systems. Quality made by Dallmeier, made in Germany! 
 
Over the years, Dallmeier has repeatedly given fresh impetus to the market with new developments and extraordinary innovations. The world’s first DVR for example, which introduced digital recording to the entire CCTV industry, came from Dallmeier. The multifocal sensor system Panomera® will have a similarly groundbreaking effect: This unique and novel camera technology will revolutionise the market and open up completely new possibilities to the video security industry. This and the extensive experience in the CCTV and IP field have led to a top position in the international market for digital video surveillance systems.
