Control commands
10.1.1
Communication via UDP
It is possible to control the smart camera using so-called UDP sockets via the Ethernet interface.
For this, the port 36701 is used.
NOTE
To communicate via UDP, you have to set the
Mode
in the camera's system menu ("
System
settings -> communication
") to "
UDP
".
The smart camera expects a
Connect
message to create a connection. Afterwards, the smart
camera will start to send result data. A
Disconnect
message closes the connection and the sender
of the
Disconnect
message has to close the socket.
The smart camera supports one active UDP connection. If a UDP connection exists, it will be
closed as soon as another
Connect
message is recieved. The camera ignores invalid messages.
10.1.1.1
