perimeter protection

Hello, I want to make a perimeter protection system based on laser beams and radio transmitter-receiver. Basically, when the laser beam is interrupted, a radio emitter sends a message to a receiver. Now, the question, since I have 10 emitters, how can I differentiate the frequency signal sent to the receiver in order to know from what direction the intruder is penetrating the perimeter. If you know of an already made such system, please let me know where I can buy it from. Thank you very much

Using different ID number for each device is the general way to proceed and you send that number ID as part of the message (or through hardware). Many wired and wireless protocols are already available.
