AXIS 212 PTZ/AXIS 212 PTZ-V- The I/O Terminal Connector

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, image storage to FTP locations, etc.

• Input - fo

r 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.

I/O terminal connector:

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.

Pin Function Description

1 GND Ground

23.3V 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 open-collector NPN tran-

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.
