SIMATRIX 648 II Videomatrix-System


The SIMATRIX 648 II is a economically priced video matrix system with up to 64 video inputs and 8 outputs.The SIMATRIX 648 II is the successor of the well-tried SIMATRIX 648, additionally providing the following:

  • LAN connection: control, programming, and diagnosis via LAN, connection of LAN-based operating devices
  • RS485/RS422 outputs for direct PTZ control of dome cameras (2 of 7 available PTZ protocols can be used at the same time)
  • All 8 video outputs can be used for switching video signals to monitors, due to a dedicated signal loss axis.

With regard to functions and pin assignment, the SIMATRIX 648 II is hundred per cent downward compatible with the SIMATRIX 648 — to the point, that even the parameter file is fully compatible — and thus can serve as 1:1 substitute in existing systems.
