AXIS Q7401 Video Encoder

Hardware Overview

Connectors and Buttons

For technical specifications, see page 62.

BNC Connector

Each video input is terminated using a coax/BNC connector. Connect a 75 Ohm coaxial video cable; the recommended maximum length is 250 m (800 ft).

Note

If the video source is connected in parallel with other equipment using a BNC T adaptor, disable the input termination by setting the 75 Ohm termination switch to OFF to avoid reduced image quality.

Network Connector

RJ45 Ethernet connector with Power over Ethernet (PoE).

NOTICE

The product shall be connected using a shielded network cable (STP). All cables connecting the product to the network shall be intended for their specific use. Make sure that the network devices are installed in accordance with the manufacturer’s instructions. For information about regulatory requirements, see Electromagnetic Compatibility (EMC) on page 2 .

I/O Connector

Use with external devices in combination with, for example, tampering alarms, motion detection, event triggering, time lapse recording and alarm notifications. In addition to the 0 V DC reference point and power (DC output), the I/O connector provides the interface to:

•Digital output – For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX® Application Programming Interface, output buttons on the Live View page or by an Action Rule. The output will show as active (shown under System Options > Ports & Devices) 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 System Options > Ports & Devices).

Power Connector

2-pin terminal block for power input. Use a Safety Extra Low Voltage (SELV) compliant limited power source (LPS) with either a rated output power limited to ≤100 W or a rated output current limited to ≤5 A.

Audio Connector

The Axis product has the following audio connectors:

•Audio in (pink) – 3.5 mm input for a mono microphone, or a line-in mono signal.

•Audio out (green) – 3.5 mm output for audio (line level) that can be connected to a public address (PA) system or an active speaker with a built-in amplifier . A stereo connector must be used for audio out.

For audio in, the left channel is used from a stereo signal.

RS485/RS422 Connector

Two terminal blocks for RS485/RS422 serial interface used to control auxiliary equipment such as PTZ devices.

SD Card Slot

A microSD card (not included) can be used for local recording with removable storage. For more information, see Technical Specifications on page 62.

Equipped with a two-way audio feature, the Q7401 enables real-time communication between the camera and the control center, enhancing situational awareness and response capabilities. This feature is increasingly valuable in security applications, allowing operators to interact proactively with on-site personnel or potential intruders.

The Q7401 also includes advanced features such as video motion detection, which allows the user to set up alerts based on detected motion within predefined areas. This capability reduces the need for constant monitoring, automatically notifying users of potential security breaches or events of interest.

In terms of connectivity, the Axis Q7401 is designed to integrate seamlessly with Axis' network video products. Its compatibility with various Axis applications enhances its functionality, allowing for advanced analytics and intelligent features that can further enhance security measures.

The robust design of the Q7401 ensures reliability in various environments. Its compact form factor allows for easy installation in space-constrained locations, and it operates efficiently in temperature variations, making it suitable for both indoor and outdoor use.

Additionally, the device supports Power over Ethernet (PoE), simplifying the installation process by allowing both power and data transmission through a single cable, thus reducing the amount of wiring required.

Overall, the Axis Communications Q7401 is an excellent choice for organizations looking to upgrade their surveillance systems to meet modern security demands while benefiting from advanced features and reliable performance.
