Getting a high quality dashcam

I'm quite tech-savvy and am interested in getting the highest quality dashcam for my vehicle. 

I'm looking for a camera that offers the best in terms of resolution, frame rate, and overall image quality, especially in different lighting conditions. 

How do different dashcams perform in low-light or night conditions, and what specifications should I look for to ensure top-notch video clarity and detail? 

Also, how important is the frame rate in capturing clear footage in various driving situations?
