4-3-2 Map
The map tab shows the map tree , and all added maps are nodes of the map tree. Like
the camera tree, the node can be dragged from the map tree and drop it on the viewer.
A map is a HTML-based file. The map can embed the connecting channels and
associated DI/DO points. From the map, the user can learn the geographic position of
the connecting cameras or DI/DO points as well as the type and usage status of the
devices. The user can drag the camera icon not only from the camera tree but also
from the map, and he/she can drop it in a viewer to view the image. In addition, the
system allows the user to control the DO points on the map directly, just like the way
on the camera tree.
Inherited from its HTML base, the map supports the hyperlink function. The user can
directly click the hyperlink on the map, and the viewer will access to the linked object.
For example, a hyperlink to the Google Map has been added to the map. When the
user clicks the hyperlink, the viewer shows the associated content.
When the system has communicated with many cameras and DI/DO points, multiple
maps will helps the user to find the preferred device quickly. Also, the combination of
the map and the tour function will effectively helps the user to monitor all critical
images.
