[0010]
Next, the operation of the controller 2 in the surveillance camera system according to the present invention will be described. First, the power of each part of the surveillance camera system is turned on. Each of the monitoring cameras 1A to 1D captures an image of the monitoring area with the image capturing unit 10, converts it to an NTSC image signal, for example, with the signal transmission unit 12, and transmits it with coaxial cables 5A to 5D. The image signal is input to the image processing unit 20 of the controller 2 via the coaxial cables 5A to 5D. The image processing unit 20 creates four images of the surveillance cameras 1 </ b> A to 1 </ b> D as one image divided into four parts, and outputs them to the time-lapse video 3 at the image output unit 21.
[0011]
An operator who operates the controller 2 first inserts his IC card into the card reader of the C authentication unit 25 and performs a reading operation. The card reader is connected to the I / F unit 24 of the controller 2 via the RS232C, and the ID code read by the card reader is input to the C control unit 23 via the I / F unit 24. The C control unit 23 compares the ID code registered and stored in advance with the received ID code to determine whether or not they match. Here, if the ID codes match, it is assumed that the operator is qualified to operate, and thereafter, the operation by the C operation unit 22 becomes valid.
When the card operation of the C authentication unit 25 is not performed and when the ID code by the C control unit 23 does not match even if the card operation is performed, the operation by the C operation unit 22 is invalid.
[0012]
Next, the operation of the time lapse video 3 will be described. The image signal transmitted from the image output unit 21 of the controller 2 is input to the recording unit 31 of the time-lapse video 3 through the coaxial cable 6. The recording unit 31 records the input image signal on a video tape. An operator who operates the time-lapse video 3 first inserts his IC card into the card reader of the T authentication unit 35 and performs a reading operation. The card reader is connected to the I / F unit 34 of the controller 2 via the RS232C, and the ID code read by the card reader is input to the T control unit 33 via the I / F 34. The T control unit 33 compares the ID code registered and stored in advance with the received ID code to determine whether or not they match. Here, if the ID codes match, it is assumed that the operator is qualified to operate, and thereafter, the operation by the T operation unit 32 becomes valid. When the card operation of the T authentication unit 35 is not performed, and when the ID code by the T control unit 33 does not match even if the card operation is performed, the operation by the T operation unit 32 becomes invalid.
[0013]
As described above, in the surveillance camera system of the present embodiment, the operator's qualification is checked when operating the setting of the controller 2 that processes images and the recording device that records images (for example, time-lapse video). Unauthorized setting operations can be prevented.
