We installed 8 new cameras with a Geovision GV2008 card. All cameras are powered with 24volts. 5 of the cameras are Panasonic WV-CP484 mounted in enclosures with fans. All of the cameras were operating and giving real nice video back to the pc, then the one of them had a problem, now I get a black screen shot from that one camera. This camera gave nice video for about 15 minutes before it went black. I disconnected the bnc connector where that camera feeds into the back of the 2008 card, and the screen goes from black to the geovision blue "video lost" screen. It apprars that the camera is sending something back to the Geovision, but it is not the video the system is looking for. Can someone point me in the right direction where to begin to look?

Thank you for the replies. As for a budget, I am not realy looking to hold to one, I am just looking to have a nice working system. If you were to go with a stand alone DVR, which one would you suggest? I will most likely have between 7 and 8 cameras, and most likely would not need any more. If you feel that a Geovision would be the way to go, would a 1240 card be the way to go? I have no problem building up a pc as long as it will be accessable thru our server, and remotely. We have a security system which has the entire building perimiter wired, so I think we are good on the alarm. We believe the thieves we are dealing with have keys to our company. I will be ordering the cameras this week, as well as the DVR. Thanks again for your help.

I am looking to install a CCTV system here at my work. This is what I want to watch: 1- Front reception area which is aproximately 20' x 20'. This area has glass which faces west, and is tinted. There is sunshine late afternoon coming in from that side. There are no lights on in there at night. Ceiling height is 10'. I believe one dome. 1- Hallway leading to the side door. This hallway is about 10' long x 5' wide. No windows or glare. No light in there at night. I believe one dome. 2- Warehouse doors. The cameras will need to be mounted 12' to 15-high on a wall which is 30' directly in front of the warehouse door. The warehouse door has some early morning direct sun, but not much. this door stays open during the day, so the camera will be mounted so it views the warehouse and will catch what is outside of the door. The warehouse has no lights at night. 4- parking lot cameras. These 4 cameras will need to be mounted aproximately 20' up. I would like them to catch a field aproximately 50 feet from the building from where they are mounted. This area has real nice lighting at night. I do not need the ability to pan or zoom these cameras remotely. We would like to be able to view our cameras here at work on our network, or via the internet from remote locations. I have a Geovision set up at home, and have had real good luck with it. I built up a dedicated tower just for my Geo. Would you suggest that we get a dedicated DVR or a Geovision? Please suggest which one I should get? I have not purchased anything yet, and I am ready to go with this project. We have our service vehicles parked out back and have had several break ins. Thank you guys for your suggestions. Lew
