The government of the Dominican Republic identified the need to implement video surveillance / security monitoring systems in approximately 825 locations around the country. The project itself was to fulfill a government promise to increase security to its citizens. Provide weather- and poor-power-quality resilient video-surveillance solution for outside locations. The deployment of these 825+ surveillance/monitoring locations also called for the integration of an advanced overvoltage protection solution due to the frequency of storms in the country as well as the usual overvoltage events on the grid lines. The equipment installed on each site would be an SPD, an Inverter, a battery charger, a battery bank, and the video surveillance camera.


Mersen’s STXR SPD had the advantage of being certified for external applications due to its NEMA – 4X type certification.
