Notice to visitors and members: DO NOT PURCHASE FROM ** BRICKHOUSE SECURITY ** I recently purchased over $200.00 from them one component was defective upon receipt. They refused to exchange it claiming they do not take returns on packages that have been opened!!! How do you know its defective if you don't open the package???? Furthermore I subsequently purchased the same component locally from Walmart for $35.00 So I'm out $100.00 bucks and a bit wiser.
