ABSTRACT:
An electronic surveillance apparatus with an alarm, including a signal transmitter for producing a transmission signal, a tag for generating an alarm when the transmission signal from the signal transmitter is received while the tag is in a warning operation state, and a tag controller, which is selectively coupled to the tag, for controlling the warning operation state of the tag. The tag includes a signal receiving section, a warning generating section, a plurality of external connection terminals, a voltage dividing circuit which is connected to the plurality of external connection terminals, and a warning generation control section which is connected between the voltage dividing circuit and the warning generating section. The tag controller includes a plurality of external leadout terminals for connection to the external connection terminals, and a voltage generating section for selectively supplying at high voltage exceeding a power supply voltage of the tag to the plurality of external leadout terminals. The tag includes a power battery source for generating the power supply voltage which is connected to one of the external connection terminals, and the tag controller includes a battery level detection circuit which is connectable to the external leadout terminal through an external leadout terminal.
