You can get that relative watching you in lots of ways. One would be to export your camera configuration to .XML and just edit the .XML file manually to cut out things you don't want that person to have. Alternatively, you can back up your own full config to .XML, wipe your config and re-add just what you want that person to have, export that config as .XML and send it to them to import. They would also need to import your OpenVPN config, yes. You can restrict what that config gives them access to, but this is a little outside of the super simple VPN config I have described.
Seriously tho, in the time it has taken to discuss this just so far, you could be watching your cams in OpenVPN. It is a lot easier, and the giant step up in security is a bonus. There are kids using tools like Shodan, masscan and zmap to scan the entire internet address space in under an hour looking for cameras and other vulnerabilities. Having 554 open essentially guarantees you will be probed many times a day, all day. If there is even the slightest vulnerability in anything that you have exposed, it is a given that it has been hacked, and you likely wouldn't even know it. This is the same as being a litterbug or a shoplifter because even if you are only participating unknowingly in a DDoS botnet, you are contributing to a problem that impacts every internet user. When I hear "Oh I just open ports on my router" I see someone flinging an empty McDonalds bag out the window of a moving car. And I feel like that native American in that old 70s commercial...
So you're telling me for each camera/ip address i only need to open port 554 ? My router won't let me open 554 more than for one ip address, that's my sticking point.I don't know what you mean by "Port range 10554" this is what I keep asking about. Why are you opening up a range? You likely only need one port - 554 - for each RTSP camera. I use a VPN which doesn't involve all this cumbersome port forwarding, IMHO doing that was made obsolete (at least for our purposes) many years ago by VPNs, so I may be wrong, but you should only need the one single port on TCP (UDP RTSP is possible but it should work fine without).
I do not know if a paint by numbers exists for exporting your camera config, but there are many great tutorials for both TinyCam and XML.
Also, if that did work, then what do i type in tinycam for web port number ? Not RTSP port number.
Thanks guys.
