Furthermore, a voltage comparator integrated circuit may, for example, include the trigger means 17 such that when the received signal drops below the predetermined reference signal strength voltage the comparator generates a voltage to energize speech synthesizer 18.
  • speech synthesizer 18 although an alarm • with a conventional alarm sound may also be effective. It is also preferable to construct the present invention with compact dimensions, as the user might like to keep first portable unit 10 in his or her front pants pocket. Moreover, the user might like to place a second portable unit in a camera case to prevent theft of the camera. Hence it is desirable to use integrated circuits for providing the required functions of the present invention.

Signal discrimination means 19 then decodes the transmitted signal 14 and inquires is the code is correct. If it is correct, the alarm 18 is not triggered. However, if the code is not correct, the alarm 18 is triggered by trigger logic 21. Signal discrimination means 19 is for example, a decoder integrated circuit or a transistorbased circui .
