Older industrial monitoring systems (no WebRTC support) can display multiple Axis MJPEG streams in an HTML frame grid.
MJPEG is a video format where each frame is an independent JPEG image. The stream is delivered over HTTP using the multipart/x-mixed-replace content type. The server keeps the TCP connection open and continuously sends new JPEGs with a boundary delimiter.
Advantages of MJPEG:
Disadvantages:
Nevertheless, for custom integrations, the /axis-cgi/mjpg/video.cgi endpoint is often the fastest way to get pixels from an Axis camera into your application.
Why would anyone use MJPG in 2025? Here are three scenarios where axis cgi mjpg is still the best tool for the job.
The Axis CGI interface was designed before modern security standards. It lacks rate limiting, CSRF protection, and uses basic/digest auth which is vulnerable to replay attacks.

Implementing Axis CGI for MJPEG Video Streaming In the world of network surveillance, Axis Communications
provides a powerful and flexible interface for developers to interact with their devices through
, their proprietary API. One of the most common and robust ways to pull a live video feed from an Axis camera for web applications or third-party software is through the Axis CGI MJPEG stream 1. Understanding the MJPEG Stream URL
The primary endpoint for retrieving a Motion JPEG (MJPEG) stream from an Axis camera is /axis-cgi/mjpg/video.cgi
. This CGI script generates a continuous stream of JPEG images that are delivered over HTTP, making it natively compatible with most modern web browsers and media players. The basic syntax for the stream URL is:
The axis-cgi/mjpg/video.cgi path is a core component of the VAPIX API, used to request Motion JPEG (MJPEG) video streams from Axis network cameras. Unlike modern RTSP streams that require complex handshaking, this CGI method delivers video over HTTP using a "multipart/x-mixed-replace" push mechanism. Base Request Syntax
The most basic request to pull a live stream is as follows:http://
Authentication: By default, Axis cameras require a username and password (often root and a user-set password). In curl or browser requests, this is typically handled via HTTP Basic or Digest authentication.
Default IP: If a DHCP server is unavailable, the camera typically defaults to 192.168.0.90. Common Customization Parameters
You can append arguments to the URL to control the quality, size, and behavior of the stream: Video streaming - Axis developer documentation

developer documentation, allowing users to request live video streams from Axis network cameras using standard HTTP requests. Unlike complex streaming protocols like RTSP, this CGI (Common Gateway Interface) method delivers a continuous stream of JPEG images (Motion JPEG) that can be easily embedded in web pages or third-party applications. Core URL Syntax The primary endpoint for requesting an MJPEG stream is /axis-cgi/mjpg/video.cgi . A standard request follows this format:
The primary resource for understanding "axis-cgi/mjpg" is the Axis Video Streaming Developer Documentation, which provides the official technical specifications for requesting Motion JPEG (MJPEG) streams. Key Technical Documentation & Guides
Official Axis VAPIX API: This is the "gold standard" for developers. It explains the video.cgi request structure, including parameters for resolution, compression, and frame rate. A typical response header:
HTTP/1
Axis HTTP API Reference: A foundational document (often found as a Domoticaworld PDF) that details legacy but still widely used CGI commands for MJPEG streaming.
Migration Guide: The Axis Technology Platform Migration Guide is useful if you are working with different firmware versions (e.g., transitioning from firmware 4.xx to 5.xx), as it explains changes in how MJPEG and audio streams are handled. Implementation & Application Papers
Cross-Platform C++ Integration: A specialized paper/article describes a boost/asio solution for capturing MJPEG streams in C++ applications, which is often more robust than standard browser-based methods.
Industrial Automation (LabVIEW): For those in engineering, discussions on the NI Forums provide practical "papers" on using axis-cgi within LabVIEW environments for real-time monitoring. Typical MJPEG Request Formats
Based on these resources, the standard URL for an MJPEG stream is:http://

Understanding Axis VAPIX: The axis-cgi/mjpg Framework The Axis Communications developer ecosystem revolves around a powerful, HTTP-based API known as VAPIX. One of its most foundational and enduring components is the Common Gateway Interface (CGI) for Motion JPEG (MJPEG) streaming. This protocol allows developers to pull live video feeds from Axis network cameras using standard HTTP requests. The Core MJPEG Stream Request
The primary method for requesting a continuous MJPEG stream from an Axis camera is through the video.cgi endpoint.
Standard URL Pattern: http://
Simple Web Integration: Because MJPEG is essentially a sequence of JPEG images sent over an HTTP multipart stream, it can be embedded directly into a web page using a standard image tag:
This method is highly compatible with browsers like Chrome and Safari without requiring specialized plugins. Key Configuration Arguments
The video.cgi request supports several arguments that allow you to customize the stream on the fly. These are appended to the URL as query parameters: Older industrial monitoring systems (no WebRTC support) can
Resolution: While you can request specific sizes, it is best practice to use /axis-cgi/imagesize.cgi first to retrieve the camera's supported resolutions.
Compression: Adjusting the compression argument (typically 0–100) balances image quality against network bandwidth.
Frame Rate: The fps (frames per second) argument can be used to throttle the stream for low-bandwidth environments.
Camera Selection: For multi-channel devices or encoders, use the camera argument (e.g., camera=1) to specify the source. Authentication and Security
Accessing these CGI scripts requires proper authorization. Axis devices typically support three roles: Administrator, Operator, and Viewer.
Basic Authentication: Most integrations use HTTP Basic Authentication. You can pass credentials in the URL for testing (e.g., http://user:password@), though this is discouraged in production for security reasons.
HTTPS: For encrypted communication, Axis strongly recommends using https:// to prevent credentials and video data from being intercepted.
Modern Policy: Recent firmware versions (AXIS OS 5.x and later) may require MJPEG streams to use "Unencrypted only" password settings if certain older H.264 legacy modes are active. Troubleshooting Common Issues
Latency: Some users report delays of 7–10 seconds when using MJPEG compared to a camera's native live view. In such cases, switching to the single-frame fetch via /axis-cgi/jpg/image.cgi can sometimes reduce lag, though at the cost of a fluid frame rate.
"Error Loading Media": In modern web frameworks like Inductive Automation's Perspective , the standard "video player" components often expect file-based formats (like .mp4). For Axis MJPEG streams, an Inline Frame (IFrame) or a dynamic Image component is usually required instead. Beyond MJPEG: The Shift to RTSP and H.264
While axis-cgi/mjpg remains vital for simple integrations, high-performance applications often transition to RTSP (Real Time Streaming Protocol) for H.264/H.265 video, which offers significantly better compression. Video streaming | Axis developer documentation

The axis-cgi/mjpg/video.cgi is a specific API path used by Axis Communications cameras to deliver a live Motion JPEG (MJPEG) video stream. This feature allows developers and system integrators to pull live video into web browsers, third-party software, or custom applications without needing complex RTSP (Real Time Streaming Protocol) handshakes. 📽️ Key Technical Features An easy way to embed an AXIS camera's video into a web page
http://<camera-ip>/axis-cgi/mjpg/video.cgi
This is the simplest command. When you navigate to this URL, the camera begins streaming a Motion JPEG sequence. However, by default, many modern Axis cameras have this disabled due to security and performance concerns.
