AXIS P1347–E Network Camera
Hardware overview
Note
For technical speci fi cations, see page 57 .
I/O terminal connector - Use in applications for e.g. motion detection, event triggering, time lapse recording and alarm noti fi cations.
In addition to an auxiliary power and a GND pin, the I/O terminal connector provides the interface to:
•
Digital output
— For connecting external devices such as relays and LEDs. Connected devices can be activated by
the VAPIX® Application Programming Interface, output buttons on the Live View page or by an Action Rule. The
output will show as active (shown under
System Options > Ports & Devices
) if the alarm device is activated.
• Digital input — An alarm input for connecting devices that can toggle between an open and closed circuit, for
example: PIRs, door/window contacts, glass break detectors, etc. When a signal is received the state changes and
the input becomes active (shown under
System Options > Ports & Devices
).
Note
The I/O connector is connected to the housing (fan/heater) on delivery, and will trigger an input port event to indicate a fan
or heater error when activated. See Events, on page 36 for information on how to set up an event.
Function Pin Notes Speci fi cations
GND
1
Ground
3.3 V DC Power 2 Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
Max load = 50 mA
Digital Input 3
Connect to GND to activate, or leave fl oating (unconnected)
to deactivate.
0 to +40 V DC
Digital Output
4
Internal connection to ground when activated, fl oating
(unconnected) when deactivated. If used with an inductive
load, e.g. a relay, a diode must be connected in parallel with
the load, for protection against voltage transients.
Max load =100 mA
Max voltage = +40 V DC
