Unit connectors

Network connector - RJ-45 Ethernet connector. Supports Power over Ethernet. Using shielded

cables is recommended.

Audio in - 3.5mm input for a mono microphone, or a line-in mono signal (left channel is used from

a stereo signal).

Audio out - Audio output (line level) that can be connected to a public address (PA) system or an

active speaker with a built-in amplifier. A pair of headphones can also be attached. A stereo

connector must be used for the audio out.

SDHC memory card slot - The high capacity SD memory card can be used for local recording with

removable storage.

I/O terminal connector - Used in applications for e.g. motion detection,

event triggering, time lapse recording and alarm notifications. It provides the

interface to:

• 1 transistor output - For connecting external devices such as

relays and LEDs. Connected devices can be activated by the

VAPIX Application Programming Interface (API), by the output buttons on the Live View

page or by an Event Type. The output will show as active (shown under Event Configu-

ration > 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, and glass break

detectors. When a signal is received the state changes and the input becomes active

(shown under Event Configuration > Port Status).

• Auxiliary power and GND

Function Pin Notes Specifications

GND 1 Ground

3.3V DC

Power

2 Can be used to power auxiliary equipment.

Note: This pin can only

be used as power out.

Max. load = 50mA

Digital

Input

3 Connect to GND to activate, or leave floating (or

unconnected) to deactivate.

Min. input= - 40V DC

Max. input= + 40V DC

Digital

Output

4 Uses an open-drain NFET transistor with the source

connected to GND. 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 = + 40V DC
