AXIS 212 PTZ - The I/O Terminal Connector
The I/O Terminal Connector
Pinout and Interface
The
•1 transistor output
•1 digital input
•Auxiliary power
•Ground (GND)
The terminal connector is used in applications for e.g. motion detection, event triggering, time lapse recording, alarm notification via email, image storage to FTP locations, etc.
•Input - for connecting e.g. a push button. If the button is pressed, the state changes and the input becomes active (shown under Event Configuration > Port Status).
•Output - connects e.g. 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.
I/O terminal connector:
Pin | Function | Description |
|
|
|
1 | GND | Ground |
|
|
|
2 | 3.3V DC | Can be used to power auxiliary equipment, max 50mA. |
|
|
|
3 | Digital Input | Connect to GND to activate, or leave floating (or unconnected) to deactivate. |
|
|
|
4 | Transistor Output | With a maximum load of 50mA and a maximum voltage of 24V DC, this output has an |
|
| sistor 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. |

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.
