Canon PTZ - Fabl

The Canon PTZ device controls Canon PTZ cameras, so a rundown item can reframe a shot or recall a preset without a camera operator.

Connection

Provide the camera’s host, plus the user name and password it requires. Leave Model blank and Fabl detects the camera itself; the available ND steps and white-balance modes differ per body.

Commands

Movement

Command	What it does
Drive pan and tilt	Moves the head at a constant speed, independent of the angle of view
Stop	Stops pan and tilt movement
Go to position	Moves to an absolute pan/tilt position
Home	Returns the head to its home position
Zoom	Zooms at a speed, or to an absolute position

Presets

Command	What it does
Recall preset	Recalls presets 1-100 using the preset’s stored speed
Recall preset at speed	Recalls a preset at a speed you choose
Recall preset over duration	Recalls a preset over a fixed time

Recalling over a duration is the one to use on air: the move takes exactly as long as you asked, so it can be matched to a transition regardless of how far the head has to travel.

Picture

Command	What it does
Focus	Drives focus near or far at a speed, moves to an absolute position, toggles auto focus, or runs a one-shot auto focus
Iris	Sets the manual iris, which switches iris to manual, or toggles auto iris
Gain	Sets the manual gain in 0.5 dB steps
Shutter	Sets the shutter speed by its denominator - 60 means 1/60

State and triggers

The device reports its connection state, model and power state, and raises a trigger when the connection changes.
