AXIS P7214 Installation Guide
I/O terminal connector - Used in applications for e.g. motion
detection, event triggering, time lapse recording and alarm
notifications. In addition to an auxiliary power and a GND pin, the
AXIS P7214 has 4 pins that can be configured as either input or
output. These pins provide the interface to:
• Transistor output - For connecting external devices
such as relays and LEDs. Connected devices can be activated by AXIS VAPIX API, output
buttons on the Live View page or by an Event Type. The output will show as active
(shown under Event Configuration > Port Status) 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, and glass break detectors.
When a signal is received the state changes and the input becomes active (shown
under Event Configuration > Port Status.).
Function Pin
GND 1
3.3 VDC 2
Power output
Configurable 3 - 6
(Input or
Output)
Notes
Ground
Can be used to power auxiliary equipment.
Digital input - Connect to GND to activate, or
leave floating (or unconnected) to deactivate.
Digital output - Internal connection to ground
when activated, floating (unconnected) when
deactivated. If used with an external relay, a
diode must be connected in parallel with the
load, for protection against voltage transients.
