Sensor Operation
The transmitter unit has 8 sensor inputs. The unit lets the camera direct to the preset position as an input is supplied while it
informs the Control site about sensor (alarm) activation. In the setup menus, the time zone tables and alarm dialing tables
specify whether to make the call and where to call at.
The operator can check the transmitted image at the Control site. Image display retains until the preset time elapses when
AUTO DISC (disconnection) TIME is set, or it is ended manually when the preset time is extended with the ALM ACK button.
The following charts show how the unit processes multiple inputs.
Among inputs of a unit the smaller the input number is, the higher the priority will be.
The priority order depends on the setups as described below. The viewpoint setup has the highest priority.
A sensor activation that ALARM is set to ON in the 430 VIDEO SWITCH SETUP.
A sensor activation that AUTO DISC TIME is set to ON with a preset time in the 461 ALARM SETUP.
A sensor activation that AUTO DISC TIME is set to OFF (manually disconnected).
The edge type is convenient to detect pulsive inputs while the level type is good to ignore pulsive inputs in contrast. Besides
the detection sensitivity, the disconnection timer starts differently: when the first detection takes place in the edge type, or
when the first detection ends in the level type.
