We received the following question from a customer that watched our CCTV Camera Pros surveillance videos on youtube.

I've been watching your videos on CCTV and have found them very helpful. After an attempted burglary on my premises last week which has been burgled several times now I would like to setup a CCTV system but I'm not exactly sure what equipment would be best for me.
I already have a spare PC so I think a DVR card would probably be best.

I have a few questions that I hope you can help me with.

1. What exactly does a DVR card do? (you don't have to go into detail!)

2. How is it connected to cameras (I'm looking at the Geovision GV-600 or GV-800 series cards). Is it just a cable going directly from the card directly to the cameras? Do I need a specific type of camera?

3. Is there any other equipment I need besides a PC, DVR card and the CCTV cameras?

4. What are the benefits of recording at a higher frame rate? To me 30fps looks pretty smooth and I can't decide if recording at a higher frame rate will be necessary for me? I'm trying to decide if the GV-600 will be adequate.

Here is a satellite image of my premises.

The red blobs are where I think the cameras will be positioned and the lines are the direction they'd be pointing but I haven't fully decided yet. The green blob is where the PC is located and is where all the cameras will be connected to. Ideally I'd like to put a camera on the office which is the building to the far right but I don't know how I'd run a wire to it.

Any help would be appreciated.
