Status quo

I'm running apache2 on raspiban. I have created a web page. I would like to embed camera streams from motioneyeos as fast network camera. The cameras are located in my local network and are not accessible via the internet. Short, I would like a surveillance hub accessibile via the internet.

It should look like this:

<img src="http://192.168.0.53:8081/" alt="camera1">

Problem

The streams can't reached from outside of my home network. How can I route the stream connection via the web server to access the camera?

Approaches

I tried routing with ReWrite in .htaccess like this

Redirect 301 /camera1/ http://192.168.0.53:8081

of course same Problem.

I don't want the camera streams public because I can't protect them with a password. Unlike the website.

Would be grateful for tips or links to similar problems/solutions.
