*** PLEASE NOTE! ***
It has been brought to our attention that the original www.hik-online.com/www.simpleddns.com servers are currently down. All old existing sites on that server are currently not accessible. Users are experiencing an "unknown error" on the ivms-4500 app and a blank screen through the web browsers. If the customer needs to access their DVR/NVR, they should create a login using the public IP address (use www.whatsmyip.com to obtain that information).
