2010年12月29日 · Yes, this is why I can't see a problem in using PAL or NTSC cam as long as the DVR can "understand" both standards. NTSC camera -----> NTSC DVR (records in h.264) -----> Playback h.264 on pc with some software client through ethernet port

2012年5月28日 · There's no correlation between shutter speed and recording framerate. None. You could set your DVR to record at 7fps and your camera's shutter speed (IF it allows you to adjust it) to anything from 1/10s to 1/10,000s.

2013年4月26日 · Fastrax III camera documentation specifies that you can select between PAL and NTSC formats by setting a certain DIP Switch. Based on this I went ahead with the purchase.

2013年9月16日 · 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.
