You can activate the area search mode by pressing the area search
button ().
This mode allows the user to draw blocks directly on the camera windows
by using the left mouse button, which causes the system to search
for recordings which have movement on the drawn areas. The found recordings
will be updated automatically on the timeline. Be aware that the area
search requires above normal resources and thus may be slow. You can
erase the drawn areas by using the right mouse button. You can return
to the normal mode by pressing the area search button again. The drawn
regions will remain on the memory until the record viewer is closed.
