’Alarm’ connector at the rear panel of NetCam1 and NetCam6:
Connectors ’IN OUT’ resp. ’Alarm I/O’ for NetCam6 and NetCamPlus:
All inputs are electrically isolated by means of opto-couplers. Therefore the inputs re-
quire an operational voltage of 5 to 12 V DC, at the correct polarity. At 12 V the re-
quired current is below 4 mA. Note that any external voltage source should not be
connected to the ground of the housing!
F
Attention: Any voltage in excess of 12 V DC could damage the input!
In case galvanic isolation is not desired, internal power of the NetCam unit has also
been made available at a pin of the connector. This facilitates direct connection of an
ordinary powerless contact or key terminal.
