Next, the operation will be explained.

A video signal from a television camera 11 photographing the caution area 12 is sent to a change identification signal transmitting device 15. At this time,
The attitude of the television camera 11 is controlled by the zoom lens 2 and the rotary table 3, and the attitude control information is constantly sent from the zoom lens 2 and the rotary table 3 to the azimuth control circuit 4. The azimuth control circuit 4 detects the difference between the attitude position information of the television camera 11, which is transmitted from the change identification signal transmitting device 15 and indicated by the angle of view and rotational position, for example, and the attitude control information sent from the zoom lens 2 and the rotary table 3. controls the drive of the zoom lens 2 and the rotary table 3 so that
The television camera 11 can be positioned in a predetermined posture.

Among the abnormality detection sensors 1a to lc, which are installed at predetermined positions in the warning area 12 and are configured, for example, infrared cutoff sensors,
When any abnormality detection sensor 1a is activated by some intruder, a detection output identification signal i corresponding to the abnormality detection sensor 1a is output to the change identification signal transmitter 15, and the detection output identification signal i is transmitted via the information transmission path 16. receiving station device 5
will be forwarded to. In response, the receiving station device 5 accesses the detection memory 6, refers to the index section 6a, and extracts intrusion detection importance information (important degree information), and sets the intrusion detection importance degree information in the internal memory of the receiving station device 5.
The position information in the detection data 6c stored in b, that is, the position information with 9 rotations of the angle of view, etc., which is posture information, is transferred to the information transmission path 16.
The angle of view is the attitude information that is transmitted to the change identification signal transmitting device 15 via the directional control circuit 4 and read out to the orientation control circuit 4.

Based on the rotational position information and the like, the azimuth control circuit 4 controls the driving of the rotary table 3 and the zoom lens 2 in order to adjust the attitude of the television camera 11 to the required attitude.

Under such control conditions, for example, the abnormality detection sensor lc
When activated, the detection output identification signal i corresponding to the abnormality detection sensor la is output to the change identification signal transmitting device 15 in the same way as described above, and the detection output identification signal i is transferred to the receiving station device 5 via the information transmission path 16. be done. In response to this, the receiving station device 5 accesses the detection memory 6 and index section 6
a, and reads intrusion detection importance information (importance information) from the detection data 6C stored in the detection data section 6b specified by the index section 6a. Next, the superiority (urgency) between the intrusion detection importance information of the abnormality detection sensor la already set in the internal memory of the receiving station device 5 and the currently read intrusion detection importance information of the abnormality detection sensor lc.
For example, if the abnormality detection sensor lc is preset to be superior to the abnormality detection sensor la, the abnormality detection sensor la already set in the internal memory of the receiving station device 5 is determined. The intrusion detection importance information is rewritten and set to the intrusion detection importance information of the abnormality detection sensor lc, and becomes position information, that is, posture information, in the detection data 6C stored in the detection data section 6b corresponding to the abnormality detection sensor lc. The 9-rotation view angle position information, etc. are transmitted to the change identification signal transmitting device 15 via the information transmission path 16, and the 9-rotation view angle position information, etc., which serves as the read attitude information, is delivered to the azimuth control circuit 4. Based on this, the azimuth control circuit 4 controls the drive of the rotary table 3 and the zoom lens 2 in order to adjust the attitude of the television camera 11 to the required attitude.

On the other hand, when the detection output identification signal i is transferred to the receiving station device M5 via the information transmission path 16, the receiving station device 5 accesses the detection memory 6 and index section 6
a, and detect the intrusion prevention device M from the detection data 6c stored in the detection data section 6b specified by the index section 6a.
The operation procedure (operation control information) for 9c is read out and transmitted to the change identification signal transmitting device 15 via the information transmission path 16, and transmitted from the change identification signal transmitting device 15 to the intrusion prevention equipment drive circuit 10, The intrusion prevention device 9C installed inside or in the vicinity is activated, that is, the intrusion prevention ring is closed, an intrusion warning bell is sounded, and other monitoring stations are notified of this based on a series of operating procedures.

Note that when the detection output identification signal i corresponding to the abnormality detection sensor la is output to the change identification signal transmitting device 15, and the detection output identification signal i is transferred to the receiving station device 5 via the information transmission path 16, the reception The station device 5 notifies the abnormality notification device 8 of the occurrence of the abnormality, and notifies the operator of the occurrence using, for example, a buzzer or a lamp, and broadcasts the image taken by the television camera 11 on the display of the monitor device 18. When the operator confirms the occurrence of such an abnormality using the abnormality notification device 8 or the monitor device 18, the operator presses the confirmation button on the panel switch 7 and notifies the receiving station device 5 that the abnormality occurrence confirmation has been completed.

Furthermore, in addition to the above-mentioned confirmation mechanism, the panel switch 7 is used to select one of the television cameras 11 according to the operation of the operator, move its posture vertically and horizontally to stop it at the position intended by the operator, and detect abnormalities.

When the detection output identification signal i corresponding to the abnormality detection sensor la is output to the change identification signal transmitting device 15, and the detection output identification signal i is transferred to the receiving station device 5 via the information transmission path 16, an intrusion detection interrupt is generated. Step 5T to start processing
(2)), the receiving station device 5 accesses the detection memory 6, refers to the index section 6a, and reads the detection data 6 stored in the detection data section 6b specified by the index section 6a.

If so, proceed to step 5T(7) or later, and if No, the importance I of the detection output identification signal i generated by the interrupt is greater than the priority of the importance I 'tT of the detection output identification signal i currently in operation. Step 5T(S)
), If NO, return to the intrusion detection interrupt in step 5T(6) '), If YES, set the detection output identification signal i generated by the intrusion detection interrupt to the operating importance level in step 5T(7)), The attitude information corresponding to the detection output identification signal i generated by the detection interrupt and the operation procedure (operation control information) for the intrusion prevention devices 9a to 9C are read from the detection memory 6, and the attitude information is transmitted to the information transmission path 16. The change identification signal is transferred to the direction control circuit 4 via the change identification signal transmitting device 15, and attitude control of the television camera 11 is started. Intrusion prevention equipment drive circuit 10 via change identification signal transmitter 15
and activates the intrusion prevention devices 93-9C (step 5T(8)). Next, the TV camera 11 enters the operating state (step 5T(9)), and after the operation is completed, enters the operator confirmation state (step 5T(10)).
When the operator presses the confirmation button on panel switch 7,
