gmlNetworkCamControl Class Reference

Detailed Description

A synchronous driver for the SONY EVID-30(31)(P) and EVID-100(P) pan / tilt / zoom video camera unit.

Synchronous means that only one command can be executed at a time. This is less powerfull than the original "gmlNetworkCamControl.tcl" driver but I couldn't deal with the bogus answers from some camera units. Commands are still asynchronous in the sens that they return immediately and will call a user-provided callback when the action has actually completed.

TODO: make this class a gmlEventSource. TODO: allow to queue commands.

Public Member Functions

constructor args

-port	In case of a connection to a local serial port, the port number. Numbered from 1.
-viscaId	The VISCA identificator of the camera (from 1 to 7). Can be set from the back of the SONY camera.

destructor

send command args

Send a commend to the camera unit. The command argument is one of the following; it is followed by parameters as necessary. If required, a callback script can be added as an extra argument. It will be called (asynchronously) upon completion, eventually with arguments in the case of the accessor commands.
