They are great to deal until they finish the job and get your check. We have called Mike dozen of times but he either give us an excuse or just ignore our calls, text and emails. It is very sad because we though it was a friendly business and right now we have a system that cost us over $7000 but some cameras are no longer working. I will update this review if they contact me in the future and fix what is not working and we paid for. I will also open a complain with the BBB very soon.
