In hikvision, there is an option to change the default port 80 . In NAT settings of hikvision, change to Manual from Auto.... and change port...
But it will not solve proplem.
Jiofi device is so much locked that you cannot change many parameters. You are behind their NAT and no option of ddns. Actually even if it has ddns it is quite useless as you are behind nat. IPV6 ddns are not offered in such devices. Hence with Jiofi you are much left with very few options.
Hikvision has Hikconnect app which is perfect to view on mobile devices. I am sure you do not config every now and then so the remote config option can be ignored, but live view is easy on Hikconnect app.
@popcornI am already using Hik-Connect app for (LAN) live view using port 8000. But for remote live view I can't use Jio, So I shifted my camera network to local ISP who charge RS. 400 per month with static IP so even I do not have to setup ddns since the ip is static.
Above is the setting for local live View.
I got the port 80 open from the local ISP. Now the remote live view works like a charm.
In Hikvision, if you just register a username (optional) & password & use platform Access you dont need so much of hassles
Unless you need to change config every 2 hrs remotely. I hardly change any config settings once it is set.
In my case, I use the platform access and use the QR code on HikConnect app on mobile and you are good to go anywhere in world with your mobile to see live view. This also is just done once. You can share this to other users using HikConnect App.
Any internet connection with no ports open on NVR/DVR with platform Access , Hikconnect app will show you the live view.
Yes I have configured my new NVR's using platform Access with QR Code, But the one of my DVR(DS-7208HGHI-SH) which is very old whose firmware does not support platform access so sadly I need to add the settings manually and also configure the port forwarding settings in the router.
@popcornI also have a doubt how the platform access on newer NVR's works without no open ports for remote view.
