This is an very good idea.
Although from a technical stand point you would need to send the data from camera to screen.
I did an experiment couple of months back streaming video off a Raspberry pi 4.
It averaged 0.5 Gigabytes an hour for 360 resolution video.
Then see what happens when someone and his friends make 500 cameras = 250 Gigabytes this would pose some decent technical issues.
I would consider having two versions of cameras
1 remote cameras these cameras would trigger to movement or whatever setting
much like wildlife cameras, and have say a 100 MB storage
2 a wired camera for vehicle backup cameras almost like most cars nowadays.
3 a drone camera. a drone which could follow you or be remotely controlled this could also be tied into streaming to twitch.
This would be a awesome addtion to dual universe.
