Axis Cgi — Mjpg

| Parameter | Description | Example | |-----------|-------------|---------| | resolution | Width x Height | resolution=640x480 | | fps | Frames per second (camera max allowed) | fps=15 | | compression | JPEG quality (0-100, 100=best) | compression=30 | | camera | Select camera (for multi-sensor or PTZ) | camera=1 | | clock | Overlay timestamp | clock=1 | | text | Custom text overlay | text=My%20Stream | | date | Show date | date=1 | | quad | Apply quad view if supported | quad=1 | | rect | Crop region (x,y,w,h) | rect=100,100,400,300 | | rotation | Rotate image (0, 90, 180, 270) | rotation=90 | | mirror | Mirror image | mirror=1 | http://192.168.1.100/axis-cgi/mjpg/video.cgi?resolution=1280x720&fps=10&compression=25&clock=1&text=Front%20Door This will generate an MJPEG stream at 720p, 10 fps, medium compression, with a timestamp and custom text. Part 3: How to Consume the MJPEG Stream Method 1: HTML <img> Tag (Simplest) The most surprising fact: you can embed an Axis MJPEG stream directly in a web page using a static image tag.

The low latency helps with real-time object detection. 3. Legacy SCADA and Control Rooms Older industrial monitoring systems (no WebRTC support) can display multiple Axis MJPEG streams in an HTML frame grid. 4. Debugging and Field Testing Technicians use /axis-cgi/mjpg/video.cgi to quickly verify camera focus, angle, and lighting without specialized software. Part 7: Beyond MJPEG – Other Useful Axis CGI Endpoints While MJPEG is king for streaming, check out these related Axis CGI endpoints:

| Endpoint | Purpose | |----------|---------| | /axis-cgi/jpg/image.cgi | Single JPEG snapshot | | /axis-cgi/com/ptz.cgi | Pan, tilt, zoom control | | /axis-cgi/param.cgi | Read or set configuration | | /axis-cgi/io/port.cgi | Control digital I/O ports | | /axis-cgi/operator/search.cgi | Search recorded video | axis cgi mjpg

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(); );

Introduction In the world of network surveillance and embedded video systems, few combinations have proven as enduringly useful as Axis CGI and the MJPEG video format. For over two decades, Axis Communications—the market leader in network video—has provided a robust, well-documented Common Gateway Interface (CGI) API. This API allows developers, integrators, and power users to interact directly with the camera’s firmware via simple HTTP requests. The low latency helps with real-time object detection
