Two Way Audio
•
TCP—This protocol guarantees the complete delivery of streaming data and thus provides better
video quality. The downside of this protocol is that its real-time effect is not as good as that of the
UDP protocol.
•
HTTP—This protocol allows the same quality as TCP protocol without needing to open specific
ports for streaming under some network environments. Users inside a firewall can utilize this
protocol to allow streaming data through.
Two Way Audio
•
Half duplex—Audio is transmitted from one direction at a time, for example, from a PC holding a
web console with the camera.
•
Full duplex—Audio is transmitted in both directions simultaneously.
MP4 Saving Options
You can record live video as they are watching it by clicking
. Start MP4 Recording on the main
page. Here, you can specify the storage destination and file name.
•
Folder—Specify a storage destination on your PC for the recorded video files. The location can be
changed.
•
File name prefix—Enter the text that will be appended to the front of the video file name. A specified
folder will be automatically created on your local hard disk.
•
Add date and time suffix to the file name—Select this option to append the date and time to the end
of the file name. The date and time appears in the format YYYYMMDD_HHMMSS. An example
files name is CLI_20170713_180853.
Local Streaming Buffer Time
Due to the unsteady bandwidth flow, the live streaming may lag and not be very smoothly. If you enable
this option, the live streaming will be stored temporarily on your PC’s cache memory for a few seconds
before being played on the live viewing window. This will help you see the streaming more smoothly. If
you enter 3,000 Millisecond, the streaming will delay for 3 seconds.
Joystick settings
Enable Joystick
Connect a joystick to a USB port on your management computer. Supported by the plug-in (Microsoft
DirectX), once the plug-in for the web console is loaded, it will automatically detect if there is any
joystick on the computer. The joystick should work properly without installing any other driver or
software.
Then you can begin to configure the joystick settings of connected devices.
