In April 2017, Bertin Instruments went to Boston to present its device, Second Sight MS standoff gas cloud detector, and help for the surveillance of Boston marathon. For this event, two Second Sight MS were deployed to monitor the arrival of the marathon on Boylston Street.
The Second Sight MS were placed face to face with a direct view on the finishing line: one on a rooftop and the other on a bucket on the street, with a distance of 1 km in between. Thanks to a wireless solution, the supervision and monitoring was done from the control room in the hazmat firetruck. In that configuration, the Second Sight MS were able to detect any gas attack that could happen.
