jisun126 0 Posted September 16, 2013 What differences does ntsc or pal ip camera make as I thought this was only an issue for analog cameras? I have a chance to buy some dahua pal camera but what problems will I run into? Do dahua nvr's have pal and ntsc system? Share this post Link to post Share on other sites
Securame 0 Posted September 16, 2013 Just to name one problem you will bump into; lower resolutions (substreams) will be different on PAL and NTSC versions. D1 in PAL is 704x576 at 25fps, D1 in NTSC is 704x480 at 30fps. CIF in PAL is 352x288 at 25f0s, CIF in NTSC is 352x240 at 30fps. I think with Dahua you can not change from PAL to NTSC (or from NTSC to PAL) with just a firmware update, so if you buy some gear, make sure you get all PAL, or all NTSC. If you mix them up you might run into trouble (I would not want to configure a NTSC NVR with PAL IP cameras). Share this post Link to post Share on other sites
MaxIcon 0 Posted September 17, 2013 Aside from the max frame rate issue, there's the anti-flicker setting, which causes trouble when using 50 Hz settings in a 60 Hz environment, and vice versa. This is discussed in this post: viewtopic.php?p=226075#p226075 Some cameras have this as a separate setting, but on this problem was on a Dahua. Share this post Link to post Share on other sites
