Reolink or Amcrest are good brands.

Here's an example

This is the one I bought: https://www.amazon.com/Security-8-Channel-Surveillance-Recording-RLK8-800B4/dp/B07K734ZTW/

Prices on it vary a bit depending on the sales at the time. I got it for prime day last year and paid $400, haven't seen it that low since. $500 and under is a good deal, don't buy it at full price which is usually $550+
