The I/O Terminal Connector

Pinout and Interface

The 4-pin I/O terminal connector provides the interface to:
• 1 transistor output
• 1 digital input
• Auxiliary power
• Ground (GND)
The terminal connector is used in applications - for example, motion detection, event triggering, time lapse recording, alarm
notification via email, and image storage to FTP locations.
• Input - for connecting for example, a push button. If the button is pressed, the state changes and the input becomes
active (shown under Event Configuration > Port Status).
Output - connects for example, an alarm device that can be activated by Output buttons on the Live View page, or by
•
an Event Type. The output will show as active (Event Configuration > Port Status) if the alarm device is activated.

1 GND
2 3.3V DC
3 Digital Input
4 Transistor Output
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 green terminal connector on the camera.
Description
Ground
Can be used to power auxiliary equipment, max 50mA.
Connect to GND to activate, or leave floating (or unconnected) to deactivate.
With a maximum load of 50mA and a maximum voltage of 24V DC, this output has 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.
