Dallmeier bets on 3D simulation in the planning of modern video security systems

Numerous stadiums worldwide rely on the videosecurity technology of this German manufacturer. Nicolai Priller, Dallmeier 3D-Engineering team leader, explains the technical advantages of its patented Panomera technology, a decisive element in the award of projects, as well as its innovative approach to planning and implementation.

Many video installations today are extremely complex large projects. That's why, reliability and flexibility have top priority, especially in the planning phase.

How is it possible to ensure that a new video security system actually meets all customer demands?? What happens if unexpected modifications arise during the execution of the project? How can on-site installation costs be kept as low as possible?

Video security expert Dallmeier, based in Regensburg (Germany), bets on its solutions for a sophisticated 3D simulation that not only offers maximum planning security but can also react quickly and flexibly to changes.

'What we plan is what you get’

A whole team of specialists is in charge of the 3D simulation and planning area in Dallmeier. The client provides two- or three-dimensional drawings, for example in DWG format, from which engineers and graphic technicians build accurate three-dimensional simulations of the customer's environment.

If there is no other solution, even photos and information from Google Maps are enough to create models suitable for planning. Then, the complete solution (Cameras, sensors and other components) is simulated in the final 3D model of the client's environment.

This procedure is very important, For example, to detect so-called 'shadows', I mean, areas that are not captured by a camera because there are interposed objects. With the 3D simulation of the project, the problem can be addressed immediately and eliminated, relocating cameras or adding other components. In this way, the client gets an accurate planning of his future environment, in which all the details have been taken into account.

250 pixels per meter as specification

Before finishing the 3D model, workshops are organized together with the customer to define the safety objectives and prepare a technical specification and conditions. One specification could be to achieve a minimum 'pixel density' -of 250 pixels per meter (px/m) or higher- in all areas of the stadium accessible to the public.

This parameter is regulated in a DIN standard and ensures that the quality of recruitment of unknown persons is sufficient to clearly identify them in case of an investigation.. The guarantee that you get literally in the last corner the 250 px/m required is very easy with 3D simulation: color coding in 3D simulation allows you to tell exactly where the value is reached and where it would be necessary to retouch, relocating a camera or replacing it with another model.

History with rooftops

The enormous benefit of this procedure for the client was demonstrated, among others, in a project with several large stadiums. In the course of the implementation of the project it was communicated during an on-site inspection that a roof should be built for the upper stands in all stadiums..

Naturally, such a sudden change represents a great challenge for any planner, as it requires extensive changes in the location of the cameras, the selection of camera models and the overall concept. And, Of course, no more time available for it. However, Dallmeier's 3D project planning team was able to plan and implement all the necessary changes in less than two days.

From planning directly to the construction site

With a system developed by Dallmeier itself it is possible to select, in the linked product database and with a few clicks, different camera models and compose the optimal configuration. After the complete environment is finished, the system generates an exhaustive bill of materials with all components, which then serves as the basis for the order.

A special added value is the automatic creation of the so-called 'CamCards', accurate configuration documents for each of the cameras. With this information, the on-site installer knows exactly where to mount the specific camera, at what height and at what angle. The big advantage is, apart from the immense time savings, especially in planning security: it can be predicted with high accuracy how much time and work it will take to install the entire solution, because the approach minimizes unpredictable factors.

No experiments: test of the complete system in Regensburg

Decision makers in IT departments are the ones who know the problem best: complex systems are implemented and that's when the real integration work begins, with its fullness of imponderables.

That is why Dallmeier opts for another path with the Factory Acceptance Test(FAT – factory acceptance test): all components of the complete solution are assembled in the Dallmeier FAT-Centre as they will be in the final environment, testing its actual operation until everything works perfectly. Optionally, individual employees or even entire departments of the end customer can be trained in Regensburg with their future systems.

Coverage of large areas: from the stadium to cologne Cathedral Square

Another equally important factor in the decision of many operators in favor of Dallmeier's solutions is its patented Panomera camera technology., available on the market from 2011, offering up to eight sensors per system, allowing coverage of immense surfaces with an exactly defined pixel density, with much fewer cameras.

This reduces management cost while increasing driving comfort and, with it, also security. Both are responsible for a significant reduction in total operating costs.

And the systems are not only suitable for use in football stadiums, as evidenced by the numerous projects of the Regensburg company around the world, either in Macau casinos, in many logistics companies or in the Smart City area such as, For example, in Cologne Cathedral Square, where a total of eight Panomera systems provide security from 2016 and represent a solution for which more than a hundred conventional PTZ cameras would have been necessary.
