ATM is a long-standing client of DResearch vehicle electronics. DResearch video systems are used in the company’s trams and underground railway. The task was to replace existing systems from other manufacturers with the modern HydraIP recorder.

For this purpose it was necessary to adapt the previous communication protocol that was tailored to the existing systems in such a way that the HydraIP recorder can communicate with the on-board computers. In addition, an adapter box had to be designed that is plug compatible with the replacement units.

The first three prototypes have been delivered and are currently proving themselves in practice. After successful testing, a three-figure number of trams shall be equipped with the new systems in the coming years.
