Camera system, monitoring camera control terminal, and protocol changing method

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.
