At the heart of the perimeter protection system offered by us is the ALGONT-P complex, designed to guard perimeters of unlimited length. Based on M5 ACS, the system integrates with the ALGONT-Video video surveillance subsystem, thus allowing to tie together signals from security sensors, triggering alarm reactions and video system reactions. Due to the scalability and backup capabilities of M5, it is possible to create reliable perimeter protection complexes, practically unlimited in length.
