Complex Mode - Vitek VT-XL1680 User Manual

SAGA "XL" Series
The illustration shows that at any given time, a channel would record at 27 PPS
when an alarm circuit is triggered, whereas the rest of the channels within the group
will record at 1 PPS ( (30 – 27) / 3 = 1 PPS). For example, if channel 3 is triggered
to start recording at 27 PPS, channels 1, 2 and 4 start recording at 1 PPS.
Channels 5 through 16 would record at a rate which would automatically divide
available 30 PPS by 4, thus recording either at 7 or 8 PPS.
B. Complex Mode
Complex Mode event recording records exactly at the predetermined record rate for
all channels. The total record rate must be confined within the maximum record rate
allowed for the resolution.
1) Event Channel Only
The event channel records at a predetermined recording speed.
2) All Channels
The event channel records at a predetermined recording speed and triggers the rest
of the channels to record with the remaining record rate, divided equally amongst the
non-event channel.
5. RECORD QUALITY
