BE VERY CAREFUL of shitballs running security camera businesses out of their garages and pay more to go with a real company.
There seems to be an AMWAY like scam working where any idiot can proclaim himself a "security expert" and then he attempts to buy off the shelf crap and install it for 200 percent mark-up. It of course does not work correctly and your money disappears in a fog.
My Mom's company tried a guy who talked a good story and for 6500 dollars they got 2400 dollars worth of equipment that does not work. He had "references" and a collection of AMWAY like catalogues that you photo shop your name and picture on.
I have seen this locally, a guy I knew bought into it with two friends and gave it a go. It tanked and his career as a "security consultant" was short lived.
