Terminal Block wiring diagram is as follows:
This camera provides:
•
1 transistor output
- For connecting external devices such as relays and LEDs. Connected
devices can be activated by Output buttons on the Live View page or through video
management software.
•
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. The device
will detect the change in digital input and transmit the signal to video surveillance servers.
Terminal Pin Define is described as below:
Pin Name
Description
Spec
DO
(Transistor
Output)
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 transient voltages.
Max load = <100mA
Max voltage = 24V
DC (to the transistor)
DI (Digital
Input)
Connect to GND to activate, or leave floating (or
unconnected) to deactivate.
Must not be exposed
to voltages greater
than 30V DC.
DIO PW
Electrically connected in parallel with the connector 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
DIO GND
Ground
