The time of long commuting is over – at least for numerous Istanbul citizens. Due to
the new Eurasia Tunnel, the time of travel can be a shortcut from up to 110 minutes
to less than 15 minutes – nearly 107 meters under sea level. The most advanced
subsea tunnel connects the European part of Istanbul with the Asian part of the city.
Bosch is playing a key role in the venture by providing a comprehensive safety and
security solution consisting of a video surveillance system, a fire alarm system and an
access control system. All systems are managed by Bosch’s Building Integration
System (BIS) and are open to third-party integration.

With an expected 120,000 vehicles per day basis passing through the tunnel, “the
safety of Eurasia users is our number one priority in the operation phase,’ the
operators state. The flow of this immense number of cars is analysed on a 24/7 basis
by an Automatic Incident Detection System based on cameras. The core of incident
detection is the Bosch video surveillance system that includes a smart mix of Bosch’s
network cameras to meet the varying requirements of the total installation.

The FLEXIDOME IP 7000 VR, for example, is used for areas in which conditions can
get tougher thanks to their excellent weather and vandalism resistance rating, as is
the case with the Eurasia Tunnel being located in an earthquake- and flood-prone
area. In poorly lit areas the DINION IP starlight 8000 MP fixed box camera provides
detailed colour images, where other cameras would have already switched to
monochrome. Besides its ability to gather relevant details, it also improves security
substantially, due to video analytics including colour filtering in scenes with minimum
ambient light. In case it is needed to track, locate and zoom in on objects of interest,
the AUTODOME IP 5000 HD moving camera provides the answer to complement the
DINION IP 7000 HD fixed box cameras already provided with excellent images in HD
quality. The built-in video analytics of selected cameras supports operators in
identifying accidents immediately and automatically, enabling rescue teams to be
dispatched quickly and guided accurately.

The two-story road construction enables fast passage of the tunnel by car. The Bosch
solution provides an access control system that monitors the tunnel at more than 40
points over its five kilometres length.

The Bosch Modular Fire Panel 5000 series with 5,500 peripheral devices consisting of
automatic detectors, sounders and strobes as well as manual call points helps to
detect fire fast. More than 100 emergency telephones in every tube at a distance of
50 metres, as well as several escape doors in the tunnel, provide additional safety for
travellers.
