I have searched and cannot find a solid answer.
I am contemplating installing a CK2+ to look after around 6 cameras locally (same network). I am wondering if you could adopt a remote camera (or two) at a different location (different network/ip) and manage that camera/s to update it and record the footage on the CK2+?
Bandwidth would not be a problem for the remote camera stream but just wanted to try and keep costs down by utilising a single CK2+, as it would work out to be quite expensive to have to have two CK2+ for both sites.
throwing ideas around to see what can work?
I believe what you are looking for is Layer 3. While I have tested it and it does work, I cant say it is super reliable. Maybe one of the Admins can confirm it works or not.
While you can configure cameras over L3 with port forwarding, the recommended way to connect them is over a VPN tunnel between the two sites. This is pretty quick and easy to establish if you are using UBNT gateways at both sites.
