Camera System, Monitoring Camera Control Terminal, and Protocol Changing Method

1. A camera system comprising: a monitoring camera control terminal; and a monitoring camera apparatus which is connected to the monitoring camera control terminal through a network, wherein the monitoring camera control terminal and the monitoring camera apparatus respectively communicate according to a plurality of protocols which define messages instructing a variety of settings and operations between the monitoring camera control terminal and the monitoring camera apparatus, wherein the monitoring camera control terminal uses a first protocol to request the monitoring camera apparatus to send setting information related to the monitoring camera apparatus, wherein the monitoring camera apparatus sends the setting information to the monitoring camera control terminal in response to the request from the monitoring camera control terminal, wherein the monitoring camera control terminal receives the requested setting information from the monitoring camera apparatus, and if the requested setting information does not match the setting information stored in a storage part of the monitoring camera control terminal, the monitoring camera control terminal changes the first protocol to a second protocol.

2. The camera system according to claim 1 , wherein the monitoring camera control terminal uses the first protocol to request the monitoring camera apparatus to set the settings of the monitoring camera apparatus and to obtain the setting information of the monitoring camera apparatus, and wherein the monitoring camera apparatus sends the setting information to the monitoring camera control terminal in response to the request to obtain the setting information from the monitoring camera control terminal.

3. The camera system according to claim 2 , wherein if the received setting information matches the setting information stored in the storage part of the monitoring camera control terminal, the monitoring camera control terminal sends a second request to the monitoring camera apparatus to obtain motion image data; wherein the monitoring camera apparatus sends the motion image data to the monitoring camera control terminal in response to the second request of the monitoring camera control terminal to obtain the motion image data, wherein the monitoring camera control terminal receives the motion image data from the monitoring camera apparatus, and if the information obtained by analyzing the motion image data does not match the setting information stored in the storage part, the monitoring camera control terminal changes the first protocol to the second protocol.

4. A monitoring camera control terminal which is connected to a monitoring camera apparatus through a network, wherein the monitoring camera apparatus and the monitoring camera control terminal respectively communicate according to a plurality of protocols defining messages instructing a variety of settings and operations between the monitoring camera apparatus and the monitoring camera control terminal, said monitoring camera control terminal comprising: a unit which uses a first protocol to request the monitoring camera apparatus for information related to the monitoring camera apparatus; and a unit which receives the requested information from the monitoring camera apparatus, and if the requested information does not match the setting information stored in a storage part of the monitoring camera control terminal, changes the first protocol to a second protocol.

5. The monitoring camera control terminal according to claim 4 , wherein the monitoring camera control terminal uses the first protocol to request the monitoring camera apparatus to set the settings of the monitoring camera apparatus and to obtain the setting information of the monitoring camera apparatus, wherein the monitoring camera control terminal receives the setting information from the monitoring camera apparatus, and if the setting information does not match the setting information stored in the storage part of the monitoring camera control terminal, the monitoring camera control terminal changes the first protocol to the second protocol.

6. The monitoring camera control terminal according to claim 5 , wherein if the received setting information matches the setting or operation information recorded in the storage part of the monitoring camera control terminal, the monitoring camera control terminal sends a second request to send the monitoring camera apparatus to obtain motion image data, and wherein the monitoring camera control terminal receives the motion image data from the monitoring camera apparatus, and if information obtained by analyzing the motion image data does not match the setting information recorded in the storage part, the monitoring camera control terminal changes the first protocol to the second protocol.

7. A protocol changing method for a monitoring camera control terminal which is connected to a monitoring camera apparatus through a network, wherein the monitoring camera apparatus and the monitoring camera control terminal respectively communicate according to a plurality of protocols defining messages instructing a variety of settings and operations between the monitoring camera apparatus and the monitoring camera control terminal, said control changing method comprising the steps of: using a first protocol to request the monitoring camera apparatus to send setting information related to the monitoring camera apparatus; and receiving the requested setting information from the monitoring camera apparatus, and if the requested setting information does not match the setting information stored in a storage part of the monitoring camera control terminal, changing the first protocol to a second protocol.

8. The protocol changing method according to claim 7 , wherein the first protocol is used by the monitoring camera control terminal to request the monitoring camera apparatus to perform setting of the monitoring camera apparatus and to obtain the setting information of the monitoring camera apparatus, and wherein the setting information is received from the monitoring camera apparatus, and if the setting information does not match the setting information stored in the storage part of the monitoring camera control terminal, the first protocol is changed to a second protocol.

9. The protocol changing method according to claim 8 , wherein if the received setting information by the monitoring camera control terminal matches the setting information stored in the storage part of the monitoring camera control terminal, a second request to obtain motion image data is sent to the monitoring camera apparatus, and wherein the motion image data is received from the monitoring camera apparatus, and if information obtained by analyzing the motion image data does not match the setting information stored in the storage part, the first protocol is changed to a second protocol.
