: Specifies the camera source channel on multi-channel video encoders or panoramic cameras (e.g., camera=1 ).
Request a Motion JPEG video stream. curl. HTTP. curl --request GET \ --user ":" \ "http:///axis-cgi/mjpg/video.cgi" GET /axis-cgi/ Axis developer documentation
function processStream() reader.read().then(( done, value ) => if (done) return; // Convert bytes to string, parse JPEG frames, and render to canvas // (Implementation omitted for brevity) processStream(); );
Minimal processing time makes it excellent for real-time PTZ (Pan-Tilt-Zoom) tracking.
Understanding Axis CGI and MJPEG Streaming Axis Communications is a pioneer in network video solutions. Many developers and integrators use Axis network cameras to capture live video for custom applications, web pages, and security software. The core mechanism behind this integration involves Using Common Gateway Interface (CGI) commands to request a Motion JPEG (MJPEG) video stream. axis cgi mjpg
HTTP/1.1 200 OK Server: Axis HTTPD/2.43 Connection: close Content-Type: multipart/x-mixed-replace; boundary=--myboundary Cache-Control: no-cache Pragma: no-cache
However, "axis cgi mjpg" remains the most direct, browser-compatible method for simple, real-time video display without relying on plugins or HTML5 video codec support.
Here are complete example URLs demonstrating parameter combinations:
curl --anyauth --user "root:password" "http://192.168.0.90/axis-cgi/param.cgi?action=list&group=Properties.Image.Resolution" : Specifies the camera source channel on multi-channel
The "axis cgi mjpg" format is highly compatible with Python's OpenCV library. While OpenCV can read RTSP streams natively, the MJPEG over HTTP approach is often simpler for firewalls and basic setups.
: Rotates the image clockwise in degrees. Accepted values are 0 , 90 , 180 , and 270 .
Despite the availability of newer codecs, MJPEG remains highly popular for web-based viewers, legacy system integrations, and applications where simplicity and quick implementation take precedence over bandwidth efficiency.

# Reduce bandwidth by lowering quality ?compression=20 # Lower = more compression
To request a live MJPEG stream from an Axis camera, use the following URL structure:
