Advanced Configuration
When the Rate Control parameter is set to VBR (Variable Bit Rate), the Bit Rate parameter is used
as an upper limit bit rate and the system keeps the stream at or under the target bit rate.
The I-Frame Interval parameter controls the number of P-frames used between I-frames. I-frames
are full frames of video and the P-frames contain the changes that occurred since the last I-frame. A
smaller I-Frame Interval results in higher bandwidth (more full frames sent) and better video quality.
A higher I-Frame Interval number means fewer I-frames are sent and therefore results in lower
bandwidth and possibly lower quality.
Alarm Manager:
Use the
Alarm Manager
page to set the response (action) that results from an
individual alarm. It is possible to have more than one action for a single alarm by adding additional
rules (for example, one action could capture an image and another could generate an output). If a
message is to be sent from the camera as a result of an alarm, it is necessary to define Message
Systems and set up Notification Lists (refer to
Services > Notification Lists, pg. 24
).
In general, each Alarm Rule describes a single alarm
Source
and a single alarm
Action
. For the
F
-
Series ID camera, the source of the alarm typically will be internal from the video analytics,
although it is also possible for the camera to receive alarms from another camera or device/server
on the network (such as a radar server, input/output server, ground sensor, fence system, or other
security sensor).
Alarm Source:
When the source of alarms are internal, for example, from Video Analytics, the
Alarm Source Server IP Address is set to the localhost value of 127.0.0.1 and the TCP port is the
default 1001. For internal alarms, the F
-
Series ID camera Alarm Source Device ID is set to 0.
The
Alarm Source Device Type
is chosen from a pull down
menu; not all options are available for a specific camera or
installation.
