2. EVENT RECORD SETTING
The DVR offers two distinctive methods for recording events: SINGLE mode versus
COMPLEX mode. Furthermore, both modes offer EVENT CHANNEL only and ALL
CHANNELS mode for a total of four possible event recording options.
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. The ST series offer a maximum of 120 PPS in CIF
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 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.
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.
Normal record is set to 1 PPS, and the remaining
available record rate of 15 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 15 PPS
plus the sum of the record rate of the remaining
channels 15 PPS, hence the total of 30 PPS, the
maximum allowed record rate for D1 resolution.
