I am looking for suggestions on setting up cameras in this years haunt to record the scares and to make a dvd. I was thinking of using my computer and a dvr card to record to disk the activity. One card I looked at was by Geovision. Has anyone else done this ? pro's con's which types of camera's to use. Will the ones they sell at harbor freight work ok ? Wallmart here has Homeland brand security camera's that are night vision capable and have sound ?
