WebHMI Docs

Nowadays, IP camera's manufacturers does not provide unauthorized access to video stream due to security reasons. To get video stream to WebHMI it should be without login/password to access.

The solution, is the shim web server in LAN, which will transcode H.264 to MJPEG. (e.g. Raspberry Pi)

Any camera, that can show stream using rstp: or http: protocol. By default, cgi should be enabled manually in settings.
Hikvision: Configuration, Network, Advanced Settings, Enable Hikvision-CGI. Dahua: Configuration, Network, Advanced Settings, Enable Hikvision-CGI.

Tested devices list:

Dahua DH-IPC-K22

Hikvision DS-2CD2423G0-IW

It can be done with Windows machine or Linux, e.g. Rapsbian on Raspberry Pi. Let's consider using Rapsberry Pi 3B+ powered Raspbian 10.

To do this, VLC player is preinstalled with Rapsbian. To start with, login to IP-camera and check the settings, if cgi enabled and test access via link using browser. Then, copy following link to terminal and test with -vvv argument.

In the end, create a .sh script and add to autorun

cvlc -vvv -Idummy rtsp://student:Hikvision@192.168.1.58:554/Streaming/Channels/102  --sout "#transcode{vcodec=MJPG}:standard{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=192.168.1.192:8888/}"

The output should not have warning and unresolved errors such as no codecs finded Command to output and argument explanations
