4-3 Camera Tree & Map
In the display mode, the left panel below the system tab is the camera & map tree
panel. The panel has two tabs: the camera tree tab and the map tree.
4-3-1 Camera Tree
The camera tree shows the NVR and all channels that have been added to the system
as well as the subsidiary DI/DO points. The channel represents the video image that
can be played on the viewer, and there are five channel types - the general IP camera,
the PTZ camera, high-definition camera, 180 degree IP Dome camera, and 360 degree
IP Dome camera. Some specific channels equip with sub channel or digital I/O will be
shown in the tree. By observing the channel icon in the tree, the user may easily
distinguish from the status of all connecting devices. The user may also view the
image by dragging a camera icon and dropping to the viewer as well as changing the
value of the DO points.
If the sub channel function has been activated, the camera tree will show the sub
channel as a sub node of the channel in the tree. Retrieved partially from the original
camera image, the sub channel can be regarded as an independent video image that
allows the system to play and record, just like an ordinary camera image.
