Well then whats a good security system for a small store? I mean, I feel like telling my dad he should just buy a system with high reviews off amazon and pay someone to install it rather then get screwed by some company he has hired which I am sure charge him really unjustified high fees for this type of garbage quality. But then my worry is, that if he does it himself, and one camera goes bad who does he call to fix it? Like what other service do these company provide besides the initial install and fixing? What do you think is the best path ?
