Acoustic Compound Protection System
ACOMPRIS
-
Static kind of infrastructure is often vulnerable to attacks by either small arms fire (SAF) or mortars. The objects could be for instance a military forward operating base, an embassy or a post from the United Nations. As attacks may occur all the time, persistent and affordable protection is required. Especially when inhibited by civilians, ease of operations use and maintenance become more important. Often installed in remote places far away from the electricity grid, power consumption is an issue.
