I have have had 3 different CCTV systems that have Comcast as an ISP recently, after years of no issues, suddenly start having issues. All three are in restaurants and the POS system started struggling processing credit cards and other network issues. The managers reached out to the POS vendor and replaced varies parts. Nothing worked and to make sure the camera systems weren't the issue they unplugged the cameras from the network and everything worked great. Again these are 3 different DVR manufactures. They have been unplugged for weeks with no issue but we have no access from outside for the cameras now. I have also witnessed this with a convenient store, Comcast ISP and the network stopped processing credit cards until the camera system was unplugged.
Has anyone else had similar experiences? Any workarounds?
Thanks,
Rick
