The Amcrest cams look identical to those (physical and specs) and they are half the price.

One example on Amazon...

Are you looking at day time footage? Even a really cheap cam will look great during the day, it’s how they perform at night that separates them.

Also at night time, even though I’ve only attached a still make sure you check out videos with motion, so a person or car going by, again some cams will look good at night but you’ll end up with serious motion blur with movement which makes the point of having then recording a bit pointless.

This is a still frame from my 4Mp 5442 3.6mm cam



And this is a still from my old 2Mp 5231-ze cam

I should also add that I’ve configured both cams with manual settings to try and get the best night time captures so ensuring that the cams gives you that level of control is also very important.

I don't know how good these are, but the price and specs seem decent:

REOLINK PoE IP Camera Outdoor 5MP(2560x1920 at 30 FPS)

$39.99 on Amazon and other places. I don't have a lot of experience with Reolink so YMMV.

Reolink is notoriously difficult with BI. Search that one before purchasing.
