English term or phrase:ping filters
ACS is capable of scanning any single range of IP addresses or a full subnet in search of cameras to manage. In our case, we had it scan three different class-C subnets. ACS first uses a simple ping to find IP addresses that are active and then performs a more intensive scan for video cameras culled from that subset. This works fine, but to keep it working, you can't have ICMP (Internet Control Message Protocol) ping filters between you and your cameras. The upside is that you don't need static IP addresses on your cameras, just on the ACS console.
