AXIS Q7404 - Unit connectors

Unit connectors

Network connector - RJ-45 Ethernet connector. Shielded Cat-5e or Cat-6 cables are recommended.

Power connector - Power input. Use the supplied power adapter or an external power supply 8-20V DC, max.

16.1W.

Video inputs - AXIS Q7404 supports four video sources (VIDEO 1 - VIDEO 4). Each video input is terminated using a coax/BNC

connector. Use a 75 ohm coaxial video cable; recommended maximum length is 250 meters (800 feet).

Note:

If the video source is to be connected in parallel with other equipment using a BNC T adaptor, disable the input termi-

nation by setting the 75 ohm termination switch to OFF. Failure to do so may cause reduced image quality.

Audio connectors - AXIS Q7404 has two audio connectors connected to video channel 1:

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

• Audio out – 3.5 mm 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.

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

recording and alarm notifications. The AXIS Q7404 has 2 configurable inputs/outputs per video channel.

These provide the physical interface to:

• Digital output - For connecting external devices such as relays and LEDs. Connected devices can be

activated by VAPIX®, output buttons on the Live View page or by an Event Type. The output will show

as active (shown under Events > Port Status) if the alarm device is activated.

• Digital input - An alarm input for connecting devices that can toggle between an open and closed circuit, for example:

PIRs, door/window contacts, glass break detectors, etc. When a signal is received the state changes and the input becomes

active (shown under Events > Port Status).

Pin assignments:

Function Pin number Description

GND 1 Ground

DC Power 2 Power input 8-20V DC, max 16.1W

Function Pin number Notes Specifications

GND 1 Ground

3.3VDC Power 2 Can be used to power auxiliary equipment.

Note: This pin can only be used as power out.

Max load = 250mA

Configurable

(Input or Out-

put)

3 - 4 Digital input - Connect to GND to activate, or leave floating (or uncon-

nected) to deactivate.

Min input = - 40V DC

Max input = + 40V DC

Digital output - Uses an open-drain NFET transistor with the source con-

nected 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
