Since the monitoring camera PCs 5a, 5b and 5c have an incoming call function, they automatically receive an incoming call from a caller and monitor the images projected by the monitoring cameras 6a, 6b and 6c as video data. Can be sent to the side.

Surveillance cameras 6a, 6 for obtaining optimum images
The squeezing of b and 6c and the like is remotely operated from the monitoring PC 1 by the PB signal.

On the surveillance side, an image can be easily obtained by dialing the telephone number of the surveillance camera extension telephones 41a, 41b, 41c located at the place to be monitored.

The monitoring camera PCs 5a, 5b, and 5c can be automatically turned on / off by a tone signal of an extension telephone. Therefore, when monitoring, when a command is given from the monitoring PC 1, a monitoring image is immediately obtained. Is possible, and
You can easily cut it when you no longer need it.

Next, the operation of the monitoring system will be described. 1. The monitoring camera PC 5 and the monitoring camera 6 which are child terminals are installed at a place where video monitoring is required (there is an existing extension telephone), and connected to the extension telephone 41.

2. The monitoring PC 1 is used as a parent terminal. The telephone is installed at an arbitrary extension telephone and connected to the extension telephone 21. The place where the monitoring PC 1 is installed is a monitoring center.

3. When monitoring is necessary or periodically, an extension call is made from the parent terminal 1 to the child terminal 5 having the monitoring camera 6.

4. The PBX 31 receives a child terminal call from the parent terminal 1 and transmits a call signal to the corresponding extension telephone 41.

5. The child terminal 5 receives the call signal,
Make a ringing tone. When there is no response at a predetermined time (when there is no person nearby and the extension telephone 41 is not picked up), an off-hook signal is transmitted to the PBX 31. When a person comes into the extension telephone entrance of the child terminal, there is no need to operate surveillance camera 6.

6. PBX 31 receives the off-hook signal and transmits a response signal to parent terminal 1.

7. The parent terminal 1 receives the response signal and transmits a monitoring start signal to the child terminal 5 via the PBX 31.

8. The child terminal 5 receives the monitoring start signal, and transmits a monitoring start acknowledgment signal to the parent terminal 1 via the PBX 31.

9. When the parent terminal 1 receives the monitoring start acknowledge signal, the parent terminal 1 sends the monitoring control signal via the PBX 31 to the child terminal 5.
Send to As for monitoring and control, the monitoring camera 6
Functions and operations, such as lighting and camera control.

10. The child terminal 5 receives the monitoring control signal, controls the monitoring camera 6 based on the control instruction, and transmits the video data created by the monitoring camera 6 to the parent terminal 1 via a line. Since the parent terminal 1 holds the final information until the next information is sent from the child terminal 5,
The video from the surveillance camera 6 is not interrupted.

11. When ending the monitoring, the parent terminal 1 transmits a monitoring end signal to the child terminal 5 via the PBX 31.

12. When receiving the monitoring end signal, the child terminal 5 ends the monitoring of the monitoring camera 6, and transmits an end processing completion signal to the parent terminal 1 via the PBX 31.

13. When receiving the termination processing completion signal, parent terminal 1 transmits an on-hook signal to PBX 31, and PBX 31 terminates the connection between parent terminal 1 and child terminal 5.

As described above, the monitoring side does not need to use any special hardware, and a normal PC with a modem can be used satisfactorily.

The control of the devices on the monitoring side can all be handled by software.

Communication and monitoring can be performed by selecting the extension telephone number of the partner to be monitored, so that the monitoring can be performed even if there are a plurality of monitoring locations, and the monitoring can be performed sequentially.

As shown in FIG. 3, a mobile phone line or a PHS
The same can be done using a line. In that case, it is possible to monitor even where there is no extension telephone.

[0076] A mobile phone or a PHS (personal
andphone system: simple type mobile phone system) The monitoring PC 1 is connected to the telephones 22a, 22b and 22c.
Can be a monitoring center anywhere.

If the monitoring camera PCs 5a, 5b and the monitoring cameras 6a, 6b are connected to the portable telephones or the PHS telephones 42a, 42b, the monitoring cameras 6a, 6b can be installed anywhere and can be moved. Can be.

The monitoring PCs 5a and 5b and the monitoring cameras 6a and 6b can be connected by the number of mobile phones and PHS telephones 42a and 42b.

When using a mobile phone or PHS, use PB
The mobile telephone repeater 32 and the public telephone repeater 33 are used instead of the X31.
