## Abstract

A monitoring camera control terminal and a monitoring camera apparatus respectively correspond to a plurality of protocols defining messages instructing a variety of settings and operations between the monitoring camera control terminal and the monitoring camera apparatus, and the monitoring camera control terminal uses a first protocol to request the monitoring camera apparatus for information related to the monitoring camera apparatus, receives the requested information from the monitoring camera apparatus, and if the requested information does not match the setting or operation information recorded in a storage part of the monitoring camera control terminal, changes the first protocol to a second protocol.

## Claims

### Claim 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 correspond 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;
the monitoring camera control terminal uses a first protocol to request the monitoring camera apparatus for information related to the monitoring camera apparatus;
the monitoring camera control terminal receives the requested information from the monitoring camera apparatus, and if the requested information does not match the setting or operation information recorded in a storage part of the monitoring camera control terminal, changes the first protocol to a second protocol; and
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.

### Claim 2 (depends on 1)

The camera system according to claim 1, wherein:
the monitoring camera control terminal uses the first protocol to request the monitoring camera apparatus to make setting of the monitoring camera apparatus and to obtain its setting information;
the monitoring camera control terminal receives the setting information from the monitoring camera apparatus, and if the setting information does not match the setting or operation information recorded in the storage part of the monitoring camera control terminal, changes the first protocol to a second protocol; and
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.

### Claim 3 (depends on 2)

The camera system according to claim 2, 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 requests the monitoring camera apparatus to obtain motion image data;
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 or operation information recorded in the storage part, changes the first protocol to the second protocol; and
the monitoring camera apparatus sends the motion image data to the monitoring camera control terminal in response to the request of the monitoring camera control terminal to obtain the motion image data.

### Claim 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 correspond 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 comprises:
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 or operation information recorded in a storage part of the monitoring camera control terminal, changes the first protocol to a second protocol.

### Claim 5 (depends on 4)

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 make setting of the monitoring camera apparatus and to obtain its setting information; and
the monitoring camera control terminal receives the setting information from the monitoring camera apparatus, and if the setting information does not match the setting or operation information recorded in the storage part of the monitoring camera control terminal, changes the first protocol to the second protocol.

### Claim 6 (depends on 5)

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 requests the monitoring camera apparatus to obtain motion image data; and
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 or operation information recorded in the storage part, changes the first protocol to the second protocol.

### Claim 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 correspond 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 comprises the steps of:
using a first protocol to request the monitoring camera apparatus for information related to the monitoring camera apparatus; and
receiving the requested information from the monitoring camera apparatus, and if the requested information does not match the setting or operation information recorded in a storage part of the monitoring camera control terminal, changes the first protocol to a second protocol.

### Claim 8 (depends on 7)
