LOL,, Back door.. Yeah I have thanks.. Also use products that get updates on Firmware and things are patched when found.. Dahua says there is an Intermediary Server DUH I said that... Plus the link you posted really kind of backs up what I was saying lol..
Server goes down? LOL. I know how it works.. As I said, Ping, and Send, However no server then no way to confirm there was device to receive said push lol.. Not Rocket Science
About my moms Basement, Kiss off, POS my mom passed away in 06. At least my mother Educated me and taught me how to read and comprehend. Reality is POS like you are still nothing more then Internet Bullies and trolls...
WTF does that have to do with P2P? Really Dude Read it.. Lets see, DMSS, or some other desktop management on your laptop or tablet and you connect it is called Shoulder Surfing, FFS you hang with your Troll friends. Leave you all to giving people BS..
By the way I still have devices that are able to be hacked seeing they have not had any updates since 2014 or before. I have tested many devices... I also only put my devices on the internet with open ports for research.. Even using a password that I have openly posted and while I have had in some cases many attempts of entry. No one has.. Because the people that were trolling my devices are not versed in Social Engineering.. Now I will say something that would put my risk higher, Using things like others name of pets, children, spouse, addresses, birthdays, hobbies and friends are most valuable. Problem is I don't use just something when I want to remember a password, I use a method and don't use full context and I don't change letters for numbers and such..
Every camera I own I personally test all hardware before I ever put it on the internet. Burp, B*
W** and other testing methods using Linux. Sure there are some things that I don't have access to that other do seeing they program firmware and other things with way more info then I have. But I have enough info to know that buying a New Camera from Dahua or Amcrest is safe to use P2P..
Love it when trolls only prove the point lol.. By the way do some research about what P2P is, It isn't something NEW
I guess he has never heard of backdoor vulnerabilities...
Or that Dahua themselves say there is an intermediary server....and thus why people don't get push notifications when the Dahua server goes down...but the same process applies regardless of manufacturer...
Most NVR’s have a mobile app that can connect via Peer-to-Peer (P2P). This setup uses an intermediary server to query the NVR, and request a port to be opened. Once that occurs, the Mobile app connects to the NVR.
