AXIS P33 Series

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 out-

put buttons on the Live View page or by an Event Type. The output will show as active

(shown under Event Configuration > 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

The following connection diagram gives an example of how to connect an auxiliary device.

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
