DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block circuit diagram showing one embodiment of the multipurpose display device of the surveillance camera of the present invention. In FIG. 1, an output video signal of a monitoring camera unit 1 for capturing an external video phenomenon to be monitored is processed into an appropriate signal by a video and audio circuit 2 and amplified, and the video signal and the audio signal are respectively converted into a cathode ray tube (CRT). ) Are supplied to the video display unit 3 and the speaker 4, and are displayed and emitted as video and audio, respectively. The outputs of the gas leak detector 5, the fire detector 6 composed of an infrared detector and the like, and the phenomenon detectors of the theft detector 7 composed of a vibration detector and the like are appropriately increased by the signal amplifiers 8, 9 and 10, respectively. The signals are amplified and supplied to the comparison units 11, 12, and 13, respectively. Then, the comparators 11, 12, and 13 compare them with predetermined reference values 14, 15, and 16, respectively, and output the outputs of these comparators to the controller (CP).
U) 17. Various control programs are stored in the ROM 18, and the control unit 17 operates according to the programs from the ROM 18 to perform various controls.
That is, when the outputs of the comparison units 11, 12, and 13 each exceed the reference value, the control unit (CPU) 17 reads out the countermeasure from the countermeasure storage unit 19 in accordance with a predetermined control program of the ROM 18, and outputs the image. / Audio signal circuit 2
The countermeasure as shown in FIG. At the same time, the countermeasure is emitted as a sound from the speaker 4 and notified. When the outputs of the phenomenon detection units such as the gas leak detection unit 5, the fire detection unit 6, and the theft detection unit 7 exceed the reference values 14, 15, and 16, respectively, the outputs of these phenomenon detection units are stored in the recording unit such as a VCR. Recording is started at 20, and the occurrence time is also recorded from the clock unit 21. Various operations and adjustments can be made by the operation unit 22. Note that the reference value is configured to be appropriately adjusted. The user inputs and stores the content of the countermeasure in advance in the countermeasure storage unit 19 composed of a RAM. For this input, an operation unit 22 including a keyboard and a liquid crystal screen is used.

In addition, the outputs of the phenomenon detecting sections such as the gas leak detecting section 5, the fire detecting section 6, and the theft detecting section 7 rarely occur at the same time, and the gas leak, the fire occurrence, and the theft occurrence are independent. And occur. Therefore, the reason why the countermeasure from the countermeasure storage unit 19 is also displayed on the video display unit 3 is, for example, in FIG.
Is displayed only in column a in the event of a fire, and the guide map also includes only the fire occurrence location, the fire extinguisher arrangement location, and the evacuation route guidance arrow for the customer, resulting in a screen that is easy to see. In the case of a fire, the evacuation route differs depending on the location between customers, for example, the second floor, the third floor, the location thereof, and the like. Therefore, appropriate countermeasures are taken based on a command from the control unit 17 according to the location of the video display device. Those are read out from the countermeasure storage unit 19 and displayed on the video display unit 3, and sound is notified from the speaker 4.

[0011]

As described above, the multi-purpose display device of the surveillance camera according to the present invention is provided with a countermeasure against a gas leak, a fire occurrence and a theft occurrence in the video display unit in response to the gas leak, fire occurrence and theft occurrence in the ordinary surveillance camera display device. Since the display is displayed and the countermeasure is announced by sound, the video display unit can be used for a variety of purposes with a simple configuration, and is extremely industrial.
