Archive media compatibility
ABB
recorders
comply
with
approved
industry
standards for SD cards and USB flash drives. ABB fully
tests the brands of SD cards and USB flash drives that
it supplies. Other brands may not be fully compatible
with this device and therefore may not function
correctly.
Recording duration
Approximate
duration
calculated
for
continuous
recording of 6 channels of analog data (for example, for
12 channels divide by 2, for 3 channels multiply by 2).
