Wow, lots to unpack here, first, I feel your pain, but I'm from elsewhere, so not the same pain. Seems you misunderstand the idea, surveillance (trading liberty for security) has historically failed to help. The original quote is from Ben Franklin "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." This is an idea aimed at governance, not local security (murder solving percentages and so forth)

Best I can offer from a place where that's not a big thing, is try to make it not a big thing where you are, many societies manage. Happy to try to help, but some context is needed from here.
