Introduction to PTZ camera's functionality
Most PTZ dome cameras store preset positions, preset tours and other functionality associated with
the dome equipment. The keyboard merely instructs the dome to carry out those functions. Think of
the keyboard as a switch that activates a particular function in the dome that you require. Not all
domes have the same functionality so if your dome does not have presets built into it you obviously
cannot use presets, regardless of the keyboard you use.
PRESETS and other functions
What is a preset? A preset is a particular area or object that the dome camera was looking at and has
been stored into its memory so when the preset is "called-up" from the keypad, the dome will select
the area again without the operator using the joystick to do this. Even the zoom at the time can be
stored with the preset. This means that you could for example store a PRESET of a car-park
