Just my opinion but I think having neighbors that look out is good.
a security system is good if someone hears it or some one responds fast.
both covers more bases.
Leaving signs to come rip you off is a bad ideal.
expensive cars, that leave every day at a certain time dead give away
stuff left in the front door, etc.
leaving the side door unlocked,
key under the mat
empty houses on the block
the list is endless.
