Axis cameras often use dedicated hardware JPEG encoders, allowing minimal CPU load even at high resolutions.

Many Axis cameras are configured to require a username and password. In such cases, a request to video.cgi will return an HTTP 401 Unauthorized status. Axis cameras typically use HTTP Digest Authentication, which is more secure than Basic Authentication but requires a multi-step "challenge-response" process from the client.
Integrating live video into custom software applications, automation scripts, or web dashboards requires a reliable, lightweight streaming protocol. For developers working with Axis Communications network cameras, the native offers a robust solution. By leveraging Axis Common Gateway Interface (CGI) scripts, you can pull high-quality Motion JPEG (MJPEG) streams directly from hardware without the overhead of heavy media servers or complex external SDKs.

Minimal processing time makes it ideal for real-time PTZ control.
. 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: fetch(streamUrl, headers: 'Authorization': Basic $auth )
Home Assistant can consume an Axis MJPEG stream with the generic_camera platform:
Axis cameras will likely retain the axis-cgi/mjpg/video.cgi endpoint for the foreseeable future to support the vast number of legacy systems that depend on it. It remains a crucial tool for developers integrating with older applications or building simple, proof-of-concept viewers.
Clients do not need heavy processing power to decode an MJPEG stream compared to complex codecs like H.265. Axis cameras typically use HTTP Digest Authentication, which
