Thanks for your help
I am helping friends update a 32 camera system and for now will be using all analog cameras. The card I was most considering was the Geovision GV-1240B-16 (X 2). The computer will be built by a geek that has the specs of the cards and experience in processors for cctv.
They might add some IP cams in the future.
They are currently using a 16 channel Avery stand alone for half of the cameras with remote viewing abilities and they want that on all 32 cams. the other cams are on an off brand stand alone DVR.
In your opinion is this a good enough card? Is there any other Tips , tricks or warnings you would input on a NVR system this size? as of now they don't seem to have a bandwidth issue with the 16 cameras
