[&move=<value>] – Move home, up, down, left, right
[&auto=<value>] – Auto pan, patrol
[&zoom=<value>] –Zoom in, out
[&zooming=<value>&zs=<value>] –Zoom without stopping, used for joystick
[&x=<value>&y=<value>&w=<value>&h=<value>&resolution=<value>] - Zoom in, out on a specific area
[&vx=<value>&vy=<value>&vs=<value>] – Shift without stopping, used for joystick
[&x=<value>&y=<value>&videosize=<value>&resolution=<value>&stretch=<value>] –Click on image
(Move the center of image to the coordination (x,y) based on resolution or videosize.)
[ [&speedpan=<value>][&speedtilt=<value>][&speedzoom=<value>][&speedapp=<value>] ] – Set speeds

Example:
http://myserver/cgi-bin/camctrl/eCamCtrl.cgi?channel=0&stream=0&move=right
http://myserver/cgi-bin/camctrl/eCamCtrl.cgi?channel=0&stream=1&vx=2&vy=2&vz=2
http://myserver/cgi-bin/camctrl/eCamCtrl.cgi?channel=0&stream=1&x=100&y=100&
videosize=640x480&resolution=640x480&stretch=0
In zoom operation, there are two ways to control it, scale zoom and area zoom.
1. [Scale zoom]: contains two control method, relative movement and continuous movement
a. relative movement -
If you trigger a relative movement, it will only zoom certain ratio and stop by itself.

http://IPAddr/cgi-bin/camctrl/eCamCtrl.cgi?stream=0&zoom=wide
The zoom ratio to move by relative movement is according to the setting of speedzoom [-5~5].

b. continuous movement -
If you trigger a continuous movement, you have to handle the stop time by yourself.
A continuous movement is convenient to integrate a joystick control.
