DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video surveillance recording system which belongs to the video surveillance technical field and can be used on a network.

[0002]

2. Description of the Related Art Conventionally, for the purpose of crime prevention, customers who use a cash dispenser at a bank or the like, and the situation in a store, etc., have been photographed with a TV camera, and a monitoring video has been recorded. Have been done. The recorded video is recorded on a storage medium such as a video tape or a hard disk of a monitoring video processing system installed at each site. For example, the system administrator of the monitoring center can check the contents of the recorded video of each site such as a bank and a store in the past week by going to the installation site or by remote control via a dedicated line. .

[0003] In order to remotely control a surveillance camera on site and check recorded images, a dedicated line is used for a line from the surveillance image processing system to a remote monitoring center instead of a public line such as the Internet. I have. The reason is that the storage device of the conventional surveillance video processing system has only a single write / read input / output channel, so that the system administrator and the hacker use the same channel. Intrudes into the surveillance video processing system via the write / read input / output channel via the Internet, and intentionally deletes the recorded video recorded in the storage device or falsifies its date / time. This is because it becomes possible. As described above, erasing or falsification of the recorded video is a serious problem in securing security.In a conventional surveillance video processing system, it is necessary to check the recorded or current surveillance video. Therefore, a dedicated line is indispensable, and an inexpensive public line or the like cannot be used.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a monitoring image in which a malicious third party cannot intrude from outside via the Internet or the like and falsify a monitoring image recorded in a storage device. It is to provide a processing system.

Has a monitoring video processing device 5 and an imaging device 7 connected to the monitoring video processing device 5, the first input / output channel 2 and the second input / output channel 3 are independently driven, and the computer 4 is connected to the external network 6.

Since the first input / output channel 2 and the second input / output channel 3 of this video surveillance recording system are independently driven, even if a malicious intruder enters this system from an external network, , Cannot reach the second input / output channel 3. Therefore, the recorded video processed by the monitoring video processing device is not destroyed or falsified by a malicious intruder.

[0007] Further, since the first input / output channel 2 is read-only, a malicious intruder can prevent the first input / output channel.
It is not possible to delete or falsify recorded video using 2. This makes the security of this video surveillance and recording system very strong.

[0008] The video surveillance and recording system having one head using a rotary recording disk as a storage device is characterized in that the storage device

And a processing circuit 12 for processing a read / write request from the second input / output channel 3, transmitting the request to the first head control circuit 11, and receiving the request.

[0009] The processing circuit 12 processes data in accordance with requests from the first input / output channel 2 and the second input / output channel 3. A write request from the first input / output channel 2 is ignored, and a read request and a read / write request from the second input / output channel 3 are arranged in time order and processed.
The data read by the head is passed to the input / output channel on the read request side.

[0010] Existing hard disks and DVD-
A RAM, a magneto-optical disk, or the like can be used. These discs are currently the most widespread recording media, so use these writable rotary recording discs,
An information processing system whose operation is determined by an electronic circuit and firmware is a relatively inexpensive and reliable system.

[0011] The video surveillance and recording system having two heads using a rotary recording disk as a storage device,
1 controls a rotary recording disk 8, a first head 9 that only reads data from the rotary recording disk, a first head driving unit 10 that drives the first head, and the first head. A first head control circuit 11 connected to the first input / output channel 2, a second head 9 'for writing / reading data to / from the disk, and a second head driving unit 10' for driving the second head. And a second head control circuit 11 'connected to a second input / output channel 2' for controlling the second head.

In the case of a video surveillance recording apparatus having only one head as described above, if a failure or failure occurs in the processing circuit 12, a write request from the first input / output channel is executed. Errors can occur. On the other hand, in the case of a monitoring and recording apparatus using a rotary recording disk having two heads in the storage device, the read-only head and the read / write-only head are controlled completely independently of each other. Such an error does not occur.

In the video surveillance and recording system in which the storage device 1 is constituted by an electronic circuit, the storage device has no movable parts, so that the durability of the system is improved and the system is compact.

External network of the video surveillance recording system
6 can be the Internet or an intranet.
