•1 transistor output - For connecting external devices such as relays
and LED’s. Connected devices can be activated by Output buttons on
the Live View page or by an Event Type. The output will show as
active (in Event Configuration > Port Status) if the alarm device is
activated.
•1 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 Event
Configuration > Port Status).

Pin 2
Electrically connected in parallel with the con-
nector for the power supply, this pin provides an
auxiliary connector for mains power to the unit.
This pin can also be used to power auxiliary
equipment, with a maximum current of 100mA.
Voltage: 12V DC,
Max: 1.2W

Pin 3
Connect to GND to activate, or leave floating (or
unconnected) to deactivate.
Must not be exposed to
voltages greater than 30V
DC.
Transistor
Output
Pin 4
Uses an open-collector NPN transistor with the
emitter connected to the GND pin. If used with an
external relay, a diode must be connected in
parallel with the load, for protection against
voltage transients.
Max load = <100mA
Max voltage = 24V DC
(to the transistor)
Be sure to refer to the pin number above the connector before you connect to
external DI/O devices.
Connect input/output devices to the camera as follows:
1. Attach the cables for the device securely to the supplied green connector
block.
2. Once the cables are connected, push the connector block into the
terminal
