Purchased a complete 8 camera, DVR system with a 3 year warranty on the DVR on or about 4/08 from them and on or about 19/20/09 the DVR quit working and a camera was bad. Called and was told to send camera was advised that they had problems with digicam and would replace camera and replace DVR with a new one. Sent camera and pictures of what the dvr was doing. After a few calls they sent replacement camera and said it would be about a week or so for new dvr to come in. Went this way for next month and half. Then they stopped answering the phone or some answering service would answer. I finally got a hold of a manager named Cynthia.She said that I was rude because I should have waited for the new Dvr to come in. She stated that 5 days for a new one or she would refund my monies for the Dvr. that was a 11 days ago she told me the new dvr was better than old one came with remote control, Sta hard drive monitor, video outputs and upgradeable. the old unit was supposed to be to upgradeable to 500GB but it was only was capable of 250gbts.it has been about 100 days with no dvr, the heart of the system .THIS A SECURTY SYSTEM NOT A TOY!! They had BBB membership but lost it on 1/11/2010.for FAILURE TO RESOLVE COMPAINTS, AND HAD A RATING OF A F FROM THEM.If they resolve this I will come give feedback on this.
