the camera server and it is recommended to elicit a module in command of another
‘internal” event (for e.g. record/reading parameter controls). This recommendation
is related with the “long” time of the ULR command realization by the camera
server.

Fig. 10. The view on the configuration of camera functioning functions controls and its
input/output parameters
The description of the input/output signals:
The configuration of the audio transmission module parameters can work in
desired parameter setting mode (“set”) or in the acquisition of information about
their actual condition (“get”). The change in functionality is realized by the
optional control no.3 defined as binary value - “true” where arrangement of
parameters (“set”) is consistent with “ camera set” and “false” controls of the
actual parameter reading state (“get”) returned in “camera get” control. The
content of the “camera set/get “ control is described on Fig. 11b:
• The camera IP address control (“remote ip address”) in optional input no.1 is a
required parameter for realization of the task connected with the record/reading
of the image stream transmission parameters; this value is defined as a chain of
signs (text) of a structure commonly used in IP address definition : [A.B.C.D –
where A, B, C parameters and D are the values of the 0 – 255 set, for e.g.
168.254.0.99]
• The “camera set/get” of audio transmission controls:
o “osd zoom” – switches on/off the OSD of actual image magnifying value
(of both the optical and digital image);
o “digital zoom” – switches on/off the digital magnification
