6.5.2.1
External Input Active or Inactive
 
Each illuminator has an external input that can be connected to any compatible device such 
as a PIR or switch. When the device connected to the lamp changes the state of its output 
the illuminator will detect this and will send the alarm to the XProtect system, an example of 
this would be a PIR detecting movement. This alarm raised from the illuminator can raise 
any event in the Milestone system, and in turn trigger other network devices connected to 
the system, or perform a multitude of user defined actions - e.g. send email 
 
6.5.2.2
Photocell Day or Night
 
Each illuminator has an integrated photocell that detects the ambient light around it. At a lux 
threshold specified by the illuminator it will determine whether it is day or night. When this 
changes the illuminator will send the alarm to the XProtect system. Again, this alarm can 
raise any system event.
