We like to switch all of the cameras (CL131s) into privacy mode when we are at home and then on when we are away.   This is also handy as it disables any of the alerts that you may have set up (stopping the emails/texts).  We designate a keypad button as the home/away button and this then toggles the random lighting and camera control programs. 
  
I do this by creating two network resources for each camera - one for enable and the other for disable.  
  
The following urls will do that for you - the rest of the setup is as described in the earlier excellent posts. 
  
Privacy mode on: 
------------------ 
path: 
/CgiPowerDown 
  
body: 
page=PowerDown&Language=0&PowerDownExec=3 
  
  
Privacy mode off: 
------------------ 
path: 
/CgiPowerDown 
  
body: 
page=PowerDown&PowerDownExec=4&Language=0&Go=Disable%20Privacy%20Mode 
  
Would be an awesome feature if we could just pass a couple of parameters to the network resource.....
