Warning Do Not sign a contract or do business with Ackerman Security. They do business out of an Atlanta Georgia PO Box *******. The #1 FLAG they're Crooks. They are a dishonest, incompetent shoestring scammer business that will try any dishonest trick there is to STOP you from CANCELLING their worthless service. Do not trust your belongings or your house or your well-being with them. They are a waste of time and $$$. There cameras and security equipment that they butcher your house installing are warrantied for 1 year. Then they tell you "you own it, it's your problem" They will not honor there warranty claims. Their warranty promises in literature are worthless. Get a SECURITY system ANYWHERE else but don't get it from Ackerman Security. Try "SimpliSafe" That's what I did. www.simplisafe.com ACKERMAN is one of the worst B/S security companies in America and should be run out of business as I suspect they will be soon at the rate there are losing customers.
