Create an action that brings up images of camera ID 12 in a large view on a client machine where the
"admin" user is logged in (we assume that the address of the server to which we are sending the URL
control is 192.168.7.2):
http://192.168.7.2/arms/servlet/BrowserServlet?cmd=clientcontrol&selector.user=admin
&selector.tool=online_monitor&action.action=show_live_stream
&action.mode=show_as_large&action.cameraid=12
Create action which draws a red box (for two seconds) onto the frame of camera ID 12 in the Online
Monitor of the "admin" user:
http://192.168.7.2/arms/servlet/BrowserServlet?cmd=clientcontrol&selector.user=admin
&selector.user=admin&selector.tool=online_monitor
&action.action=draw_bounding_box&box.x0=100&box.y0=100&box.x1=500&box.y1=500
&box.linewidth=2&box.color=red&box.text=MD&box.timeout=3&action.cameraid=12
