Xbee Interference

I have a wireless link using 2 Xbee Series 1 modules connecting my laptop (Processing) to an arduino mega. At the same time, I'm using 2 wireless cameras that run at 2.4 ghz with its own wireless receiver. I was originally under the impression that the Xbee protocol handles its own error checking (even with the same frequency near by).

I wanted to know if anyone can recommend software setting changes to both Xbee's as well as physical modifications to the antenna that may help reduce the interference.

Additional information:

  • The program works perfectly without the cameras plugged in.
  • When the cameras are plugged in, the program seems to miss some data or have it delayed.
  • When the cameras are disconnected from power, the program resumes running perfectly.
  • The baudrate is 115200
