For the more experience OSM contributors, there is also a fork called SCEE[1] that adds some extra "quests" and a ton of UI customisability!
https://wiki.openstreetmap.org/wiki/Tag:surveillance:type%3D...
So you can just add them using a normal OSM editor like EveryDoor or Vespucci
Maybe this flock camera situation would provide some impetus to getting this conversation moving again
With SCEE you can add the camera and then select it and use "edit tags" to add all the properties. I find it a nice middle ground between a full editor like Vespucci and the quick and easy SC. Haven't tried EveryDoor or MapComplete yet though (the latter's website aims to be as good as a native app would be, idk if they also have an app nowadays but it's an option either way) though
