niles 0 Posted March 11, 2010 Which DVR card spec actually controls the quality of the picture recorded. I have a GV-600-16 dvr card. It says the resolution 640 x 480, 30 fps. I am looking to replace the card with something with better resolution. Will a card that says the resolution is D1 (720 x 480) give me a significantly better picture or are there other specs I should be looking for. Share this post Link to post Share on other sites
Soundy 1 Posted March 12, 2010 Resolution and framerate are two parts of the quality equation... the other is compression. All else being equal, you won't see a significant difference between 640x480 and 720x480. It may be measurable, but it won't be noticeable in most cases. 720x480 is the upper limit for analog NTSC video capture resolution - if you want higher than that, you have to get into megapixel cameras, which realistically right now means IP cameras.
