Hi!
The DVR are not supported by win10. I suggest you to try it on win7 or win8.
First, you have to set up the IP Address, Gateway, and Primary DNS on your DVR to make sure its network compatibility. Then, download the phone app and type in your DVR account information as instruction. Input the serial number of your DVR, now you’re all set for remote access. Please also noted that it’s essential to set up the Gateway and DNS exactly the same for your DVR and computer. Otherwise, your mobile devices cannot proceed to extranet remote access.
