Scenario 2; Scenario 3 - Vitek VT-XL1680 User Manual

Please note that the total of the Single Mode event recording rate of 432 PPS
exceeds the maximum D1 resolution record rate of 120 PPS, but in reality, a total of
30 PPS is used per group at any given moment.
- SCENARIO 2 – Event Channel Only Mode at Half D1 resolution
A convenient store owner wants to record only when there's an event at Half D1
resolution at 30 PPS only on the channels that trigger alarm events.
The REC button must be off to begin alarm recording only. This setup disregards
the normal recording settings until an alarm circuit is triggered, where the channel
will start recording at 30 PPS.
The changes in Normal Record's PPS will affect the PPS transmitted will affect the
PPS transmitted over the network for VT-XL840, but would not affect VT-XL1680 as
it has a separate dedicated network transmission codec. In other words, if the
normal record rate was reduced to 5 PPS on all channels, then the VT-XL840 would
only transmit maximum of 5 PPS per channel over the network.
The total of the Single Mode event recording rate of 480 PPS exceeds the maximum
Half D1 resolution record rate of 240 PPS, but in reality, a total of 60 PPS is used
per group at any given moment.
-SCENARIO 3 – All Channels Mode at D1 resolution
The gas station owner from scenario 1 now wants to record all channels even if one
channel is triggered to record. He still wants the triggered channel to record as
close to real time as possible, and the rest of the channels to record with the
remaining available record rate.
Normal record rate is set to 10 PPS per channel,
thus allowing the event record to be at 30 PPS.
CH-SUM indicates the total of the record rate of
the channel that would start recording at 30 PPS
plus the sum of the record rate of the remaining
channels within the group of 30 PPS, hence the
total of 60 PPS, the maximum allowed record rate
for the Half D1 resolution.
Normal record rate is irrelevant in the calculation
of the total record rate as long as it does not
exceed 30 PPS, the maximum allowed for D1
resolution. The event PPS is calculated
automatically after subtracting PPS for the channel
that records on event.
