Introduction to Live View and Axis Link

Live View and Axis Link are two related technologies used in IP cameras and network video recorders (NVRs) to enable remote monitoring and surveillance. Live View allows users to view live footage from IP cameras in real-time, while Axis Link provides a link to the live video stream.

What is Live View?

Live View is a feature in IP cameras and NVRs that enables users to view live video footage from one or multiple cameras in real-time. This feature allows users to monitor their surveillance area remotely, making it an essential tool for security personnel, administrators, and homeowners. Live View can be accessed through a web browser, mobile app, or software client, providing flexibility and convenience.

What is Axis Link?

Axis Link is a technology developed by Axis Communications, a leading manufacturer of IP cameras and network video solutions. Axis Link provides a link to the live video stream from an IP camera, allowing users to access the live video feed directly from a web browser or software client. This technology simplifies the process of accessing live video and enables seamless integration with various video management systems (VMS).

How Live View and Axis Link Work Together live+view+axis+link

When Live View and Axis Link are used together, they provide a powerful surveillance solution. Here's how it works:

IP Camera Configuration: The IP camera is configured to stream live video to a network video recorder (NVR) or a video management system (VMS).
Axis Link Configuration: The Axis Link is configured to provide a link to the live video stream from the IP camera.
Live View Access: The user accesses the Live View interface through a web browser, mobile app, or software client.
Live Video Streaming: The Axis Link provides a direct link to the live video stream from the IP camera, which is then displayed in the Live View interface.

Benefits of Live View and Axis Link

The combination of Live View and Axis Link offers several benefits, including:

Remote Monitoring: Users can monitor their surveillance area remotely, in real-time, using Live View and Axis Link.
Easy Integration: Axis Link simplifies the integration of IP cameras with various video management systems (VMS) and software clients.
Flexible Access: Live View and Axis Link can be accessed through various devices, including web browsers, mobile apps, and software clients.
Scalability: The solution can be scaled to accommodate multiple cameras and users, making it suitable for large-scale surveillance applications.

Applications of Live View and Axis Link

The combination of Live View and Axis Link has various applications across industries, including:

Security and Surveillance: Live View and Axis Link are used in security and surveillance applications, such as monitoring public spaces, commercial properties, and residential areas.
Retail and Banking: Retailers and banks use Live View and Axis Link to monitor their premises and prevent theft and vandalism.
Industrial and Manufacturing: Industrial and manufacturing facilities use Live View and Axis Link to monitor their operations and ensure safety.
Education and Healthcare: Educational institutions and healthcare facilities use Live View and Axis Link to enhance security and monitor their premises.

Conclusion

In conclusion, Live View and Axis Link are powerful technologies that enable remote monitoring and surveillance. The combination of these technologies provides a flexible and scalable solution for various industries and applications. By understanding how Live View and Axis Link work together, users can take full advantage of their features and benefits to enhance their surveillance capabilities.

A. In AXIS Camera Station (ACS)

Create a layout with multiple cameras.
Right-click a camera window → Link to → Preset or Camera.
Choose:
- Go to camera X
- Go to preset on same camera
- Trigger HTTP GET (custom action)
Test: click inside the live view → linked action runs.

B. In a custom web interface (JavaScript + Axis VAPIX)

<map name="camlink">
  <area shape="rect" coords="0,0,640,480" href="javascript:changeView('camera2')">
</map>
<img src="http://axis-cam1/axis-cgi/mjpg/video.cgi" usemap="#camlink" />
<script>
function changeView(camId) 
const img = document.querySelector('img');
if(camId === 'camera2') 
img.src = "http://axis-cam2/axis-cgi/mjpg/video.cgi";
</script>

Troubleshooting Common Live View Axis Link Issues

Even with Axis’ robust engineering, links can break. Here are the top three problems and fixes:

Issue 1: The link is lagging (1-2 seconds delay).

Solution: Check your switch. Links require low latency. Ensure both cameras are on the same VLAN and there is no Wi-Fi bridge in the chain. Use CAT6 cabling.

Issue 2: The slave camera points in the wrong direction. Introduction to Live View and Axis Link Live

Solution: Your coordinate mapping is off. You must run the "PTZ Calibration" wizard in the master camera software. The master needs to know the exact physical location of the slave.

Issue 3: The link only works for 30 seconds then stops.

Solution: Check your "Maximum Connection Time" in the live view settings. Also, ensure you have not exceeded the PTZ camera’s MaxConcurrentStreams limit.

1. The Standard URL Structure

To access the live view directly, you typically enter the following address into your browser's address bar:

http://<CAMERA_IP_ADDRESS>/axis-cgi/mjpg/video.cgi

<CAMERA_IP_ADDRESS>: Replace this with the actual IP address of your camera (e.g., 192.168.0.90).
axis-cgi: This indicates you are accessing the Common Gateway Interface (API) of the camera.
mjpg/video.cgi: This requests the Motion JPEG stream.

How it works

Cameras stream frames continuously.
Motion controllers broadcast axis states (position, timestamp).
A synchronization layer matches timestamps from camera frames and axis telemetry.
The system overlays or tags each frame with corresponding axis coordinates and status.
Operators or downstream algorithms use the synchronized stream for tasks like measurement, trigger-based capture, or closed-loop corrections.
