When the first microcomputer 50 is transmitted, the SMS-related Short Message Service (SMS) text is transmitted to the remote terminal 64 through a communication network (for example, an internet network, a mobile communication network, etc.) 65, and only a heat sensor is fired. When the value of the alarm set value or more is output, it is configured to send a SMS-related fire to the remote terminal (64). That is, when an intruder occurs, the heat detection sensor and the motion sensor detect this and send an SMS message related to crime prevention, and if the intruder does not occur and only the indoor temperature is higher than the fire alarm setting value, only the SMS message related to fire is sent. (Step 203 of FIG. 4). To step 205) The crime-related SMS text and the fire-related SMS text are stored in the data storage 53 of FIG. 2 by the user. The remote terminal 64 refers to a terminal (for example, a computer, etc.) provided in a police station or a fire station as well as a terminal (for example, a mobile phone, a PDA, a notebook, etc.) carried by a user.

As described above, the heat detection sensor of the human body sensor 61 of the present invention is used in the case of the TV alarm mode for the invasion and fire occurrence in the absence of the user, and when switching between the TV viewing mode and TV listening mode. For these two cases, the first microcomputer 50 determines based on different user setting values.

The functions of the first microcomputer 50 as described above are summarized as follows.

The first microcomputer 50 generates a screen regeneration or erasure control signal. The screen regeneration or erasure control signal is generated by reading a human body sensed or undetected signal transmitted from the human body sensor 61. That is, the first microcomputer 50 generates the screen reproduction control signal when the human body detection signal is transmitted from the human body sensor 61, and generates the screen erasure control signal when the human body undetected signal is transmitted.

In addition, the first microcomputer 50 simultaneously transmits the screen reproduction control signal and the screen erasure control signal to the first image power control unit 43 and the second image power control unit 45 so that the TV screen reproduction and screen erasing are performed. do.

In addition, the first microcomputer 50 controls the sensor power control unit 47 when the TV viewing continuation button press signal is received from the TV viewing continuation button 62 so that power is not applied to the human body sensor 61. Also perform.

In addition, when the first microcomputer 50 is set to the TV alarm mode by the operation of the alarm function terminal 63, the first microcomputer 50 reads the output values of the heat sensor and the motion sensor of the human body sensor 61, and the heat sensor and the motion sensor. If the output value is greater than the set value in the security-related SMS text is transmitted to the remote terminal (64), if only the heat detection sensor outputs a value over the fire alarm set value is sent to the remote terminal (64).
