Single Mode; Scenario 1 - Vitek VT-XL1680 User Manual

SAGA "XL" Series
A. Single Mode
Single Mode event recording allows recording a specific channel at up to 30 pictures
per second regardless of the image size. When the need arises to record at a
higher rate for a specific channel and not be confined to the total available record
rate, SINGLE mode allows allocating recording rates to specific channels beyond
what would normally be available. For example, the VT-XL1680 offers only 120 PPS
of maximum recording rate in D1 resolution, but utilizing Single Mode will allow the
DVR to be configured up to 480 PPS.
Please note, however, that the maximum allowed in Single Mode is limited to the
sum of normal recording and event recording.
1) Event Channel Only
The Event Channel Only mode will allow one channel that detects any of the events
to record at the predefined record rate.
2) All Channels
All Channels mode allows the DVR to record any channel with event with up to 30
pictures per second regardless of the resolution, then divides the remaining record
rate among the rest of the channels.
Please refer to the following sample scenarios for a better understanding of the
SINGLE MODE event recording.
- SCENARIO 1 – Event Channel Only Mode at D1 resolution
The owner of a gas station wants to set up the DVR to record at maximum rate on
D1 resolution on channels that detect motion. At the same time, the owner would
like to record continuously at one picture per second.
When the REC button is on, this setup continuously takes one picture per second
until a movement is detected, where the record rate will jump to 27 PPS for the
channel that triggered the event.
Normal record rate is set to 1 PPS, and the
remaining available record rate of 27 PPS is
allocated for each channel for all 16 channels.
CH-SUM indicates the total of the record rate of
the channel that would start recording at 27 PPS
plus the sum of the record rate of remaining
channels within the group of 3 PPS, hence the
total of 30 PPS, the maximum allowed record rate
for D1 resolution.
