while in the continuous mode the camera can broadcast many megabytes every hour.  The user 
should be aware of the usage charges from the service provider that can result.  Most service 
providers offer unlimited data plans that are ideal for this type of operation. 
 
Power mode options 
 
The power switch on the back panel determines in which one of two power modes the camera 
will function; ON or AUTO.  The switch can be set to the ON position by sliding it to the left, or 
the AUTO position by sliding it to the right.  At the center position the camera is turned off. 
 
 
The ON position will render the unit always powered.  Images and notifications will be delivered 
as configured and the camera can be switched in and out of continuous mode via a text message 
from a cell phone. 
 
The AUTO position, activated by sliding the switch to the right, allows the camera to 
automatically turn itself on and off.   The camera will turn on based on the user’s schedule or in 
response to an external trigger signal.  Image acquisition and delivery will occur along with user 
notification.  The camera will then turn off, ready for the next scheduled or triggered activation.  
Since the camera is off most of the time it is incapable of receiving text commands from a cell 
phone, therefore, the continuous mode of operation is not available. This technique of 
automatically turning on and off is unique to the AUTO power switch setting, and will allow the 
camera to deliver up to 350-650 images from a single set of batteries.  See Appendix C for more 
detailed information regarding power supply considerations.
