A Bug Monitor is a small device that receives the short range radio signals transmitted by Bugs. The bug monitor is a compact unit containing a Radio Communicator, an internal digital sound recorder capable of recording for several hours, and a data connection. It acts as a base-station for Bugs.
The unit can be programmed to re-transmit its recorded events either at regular intervals or upon receipt of a coded radio signal. This re-transmission is encoded and compressed into a few seconds.
The Bug Monitor's internal battery on the unit last 72 hours and can be recharged from any normal power source.
