Installed security cameras, they still came onto the property.
So, next I installed a sign "BEWARE OF THE SECURITY CAMERA", and didn't work, infact one guy broke into my car and simply just covered his face from the canera.
So then I installed a cheap security light next to the sign that would light up when they entered.
That worked.
The light still works as a deterrent because the light makes them visible to a potential occupier. They'll fear real, immediate confrontation/violence, not some lazy policeman looking 5 minutes at the picture before moving onto something easier such as kids dealing weed.
Somehow, I can't parse this.
Now on this scale estimate how dumb someone is. If you say 2 (a little dumb) but in actuality they’re a 7 (very dumb) you underestimated how dumb they are.
See? He overestimated how dumb crooks are, and was robbed.
Totally changes the meaning of the comment if one assumes that it was a typo and OP intended to use "underestimate".
"Don't overestimate how dumb they are" is logical and correct. However, because "how dumb they are" is in the sentence, it emphasizes, well, that they are dumb, which is not what the OP intended to say.
Writing it as "don't underestimate how smart they are" is more readable, although logically, it's stating the same thing.
Even better, I would have written it as "don't underestimate how smart they can be."
Same with cars - even if you don't have a licence plate, there are tons of little fingerprints around your car that licence plate reader companies use.
I don't know... you setup deterrents, as a bluff and it took a while before one worked.
