The AXIS 2400/2401 supports the two most popular video standards - NTSC and PAL.
NTSC delivers 525 lines of resolution at 60 half-frames per second and is the common standard in the
United States; whereas PAL delivers 625 lines at 50 half-frames per second and is the dominant video
standard in Europe.
The AXIS 2400 supports NTSC, PAL and their derived modulation standards; whereas the AXIS 2401 is
supplied as either an NTSC or PAL-specific unit.
