don't waste your time!
i bought a 4 camera samsung 8 channel system from them with multiple non-functioning components, the dvr does not work for more than 3 minutes and a camera does not function either. SO FAR, i would have to strongly urge you to avoid this company, i told them 4 days ago I was having problems and still no solution. i regret buying from them. poor product and so far subpar customer service with returns/refunds
