bobgroger 0 Posted January 23, 2018 I have a couple of the newer USA model DVRs, X21A1E and X21A3E. There is no inbound external access, access is through VPN only and IP Filtering is enabled to VPN addresses. Passwords are changed except the ones that can't be. All user accounts deleted and admin password reset at least weekly. This HAS to be phoning home by itself. I am going to try an outbound firewall rule blocking all outbound traffic from the DVR IP. This is very frustrating, but at the same time I want to figure out how they are doing it. I have emailed the distributor cctv.net and cybersecurity@dahua.com, seems to be like urinating in the wind. My customers like the SmartPSS software. If there was something as easy to use that works over multiple locations and has actual security I would sure take a look.....
