INFODRAW MRS-400 User Manual v5.4.1

In the
“Video Properties”
Window you can adjust the settings of that specific video channel.
The descriptions of the settings are listed below:
Items:
Descriptions:
Enabled
Allows you to Enable/Disable the video channel
Name
Allows you to change the name of that specific video channel.
Single Encoder
When this box is ticked, that video channel will have a single encoder (Bit
Rate/ Frame Rate) for viewing/recording the video stream. When this box
is Un-ticked, this enables you to assign multiple encoders to the video
channel (one for viewing and one for recording.)
Destination
Allows you to apply settings for the multiple video encoders. Please view
the “
” section of this manual, for more
information.
Image Size
This allows you to adjust the Image Size (Resolution) of the video channel.
The unit supports the following Image Sizes:
PAL
– D1/CIF/QCIF
NTSC
– D1/CIF/QCIF
Make sure that the settings are compatible to the camera you have
(PAL/NTSC), and to the bandwidth at your disposal. For example D1 (TV
quality) will require high bandwidth, CIF can be afforded with medium
bandwidth and QCIF is the format more suitable to low bandwidth.
Frame Rate
Adjust the Frame Rate of the video channel to fit the bandwidth at your
disposal. The Frame Rate can be set to any number from:
1 to 25 fps (for PAL)
.
1 to 30 fps (for NTSC)
.
Bitrate
Adjusting the Bit Rate of the video channel changes the quality of the
video; it should be set to fit your bandwidth capabilities and your cellular
package. The Bit Rate can be set to any number from
10kbit/s to 2Mbit/s
.
Interlaced
DO NOT enable this feature on the MRS-400 units.
Detect Motion
Tick this box to activate Visual Motion Detection. For more information
view the “
” section of this user manual.
Frame Text
Tick this box to enable the frame text to be displayed on the upper-left
side of the video channel.
Sync Frames
This feature should always be
disabled
unless told otherwise.
Write Location
Tick this box to display the GPS Co-ordinates of the unit in the frame text.
The most important parameters when viewing the video streams are the
bit rate
and
frame
rate
. The bit rate is based on the bandwidth supported by the mobile network in the area.
The bit rate of all viewing channels must be less than the bandwidth. For example, if viewing
only 1 channel and the bandwidth is 200kb then the bit rate must be less or equal to 200kb.
The frame rate can be any number from 1 to 25/30 but in a low bandwidth environment
such as 200kb, 10 - 15 is more suitable.
