I'll chime back in. Get good cameras that you can actually seem something clear. Then if something happens, post the pics at the wash, to all your local e-mail contacts, and on facebook, and anywhere else close by that will let you. In the past, I have always posted a $50 reward for info.
With cameras mounted in clearly seen areas, they are the best deterrent for crime. The last incident I had was in October 2014. Guy kicked my auto cashier display, cause he was a bad a$$. Then he went through my automatic, where his tag was clearly displayed on my tag camera. Yes, there is a little aggravation dealing with the po-po. But after four times going to court, I got my $750 in money orders to cover the damages. The trick is to be persistent; calling them every day if need be.
I really think if you had cameras, the light tubes would not have been taken. But of course it is the big "unknown". And then, how many incidents do you want to happen before you decide to get a system? And yes, there are still fools that see the cameras and really do not care--especially if they need drug money.
It is up to you to secure your property and valuables the best way you see fit for your budget. But I am just a huge believe in the power of deterrent with cctv.
