Here are the salient points:
- Only in areas with guards, staff, or CCTV can you get a get an idea of what's going on in real-time. All other areas are "fogged out" or slightly greyed to represent you not knowing if anything's going on there.
- Prisoners know they cannot "safely" start fights, flash weapons/contraband, or try and escape in an area with guards or CCTV cameras
- Guards cannot "psychically respond" to incidents in the prison - they must be alerted by other staff, prisoners, or other guards
- Gaurds have a 90 degree cone they can clearly see in front of them. There is a 180 degree semicircle (peripheral vision) where they can see some things, mainly movement, with delayed reaction. There is some smaller degree of detection behind the back, a "someone is sneaking up on me" sense. This might allow an escaped prisoner to sneak past guards by waiting until they've passed during their patrol route. Or sneak up on a guard during a power outage, attack them, and take the keys and baton.
One spinoff would be a fake CCTV camera option. Consider a large cafeteria with four cameras, one on each wall. That would provide coverage of every inch of the cafeteria. Except in this case the north/south facing cameras are fakes. They look and act the same as the real CCTV cameras, but cost a quarter as much and don't actually do anything. But the prisoners don't (initially) know that.
