Can I replace the sensor with better quality?

The video quality on this camera is really bad - particularly in low light. The audio quality and options are really good.

Given its been on the market for a few years - and technology has improved - I expect there are better sensors that are available at relatively low cost. I’d rather do this than throw this one away and look for a replacement.

Is there a way I can replace the sensor with something better? Particularly better low light performance.

I’d like to retain the functionality/appearance - so the new sensor would hopefully be a direct replacement for whatever is in there now. I don’t mind soldering if needed.
