Let me ask this first, what would be the best app to use on my android phone considering I have a LTS NVR and cameras? Right now I have MVNS7000 but I have yet been able to get it to work over a external network. As long as I am at the house I can see the cameras using my internal network on WIFI. I cut WIFI off and try using external and no luck. I am using dvrlists from LTS for my ddns. I've got a program that opens the ports n my router.. Not really sure on what to check to make this work, have never learned that much about networking, any help would be greatly appreciated.
