providing power to the leds 20 when the building in an unoccupied state can give the appearance of activity in the building to deter trespassers from entering the building as another example while the example discussed above in reference to fig2 describes the camera 28 as providing the image signal u03b3 to the remote location upon the detection of the presence of a person the camera 28 can alternatively provide the image signal u03b3 at a certain time interval e g every fifteen seconds for analysis by security personnel or to be stored for review in the event a break in or other incident occurs as yet another example the controller 22 can turn on the camera 28 record images captured by the camera or cause the images captures by the camera 28 to be sent to the remote location based on the audio input signal u03b1 e g when the audio input signal u03b1 indicates the presence of a person the light and communication system 10 offers many advantages the system 10 can be installed in the standard fixture 12 with no additional wiring as the entire system 10 can be contained in a single package defined by the housing 14 and end caps 18 allowing for easy and inexpensive implementation of a communication system in a building the system 10 can be installed in a u201c smart u201d building for communication with other components for example the receiver 30 can receive the control signal u03b4 from a door ajar sensor separate from the system 10 with instructions to turn on the leds 20 alternatively the system 10 can be installed in a conventional building to transform the building into a u201c smart u201d.
