I recently watched a review by Seth of Berm Peak on YouTube about exactly what you are looking for. I have no experience with them myself.
Time mark 3:17
Also look at camera + screens for motorcycles.

I am torn between a mirror on my bike or helmet but the rear view camera looks like a great option.
if for trail use, the low cost solution is a mirror or a couple of mirrors, as others have suggested. The tech solution is a Garmin Varia radar. there is a version without the taillight, which is often on sale. My friend has this and pairs it with his handlebar mounted iPhone and Garmin Varia app. works best with a Garmin or Wahoo Computer. I use Varia RTL-515 for road, but when I head offroad to a trail it does signal me when a bike is approaching from the rer. They work great. It is just a costly solution that a mirror can solve.
Good luck!
