Not many people here will recommend box kits, but between the two, go with Lorex. At least up until recently, Lorex was Dahua OEM, so you would probably end up with a Dahua OEM that you could upgrade over time.
Stay away from Reolink unless all you care about is what time something happened. Their night time performance is horrible.
In most instances, you want to get a camera that will perform at your location for the worse situation, which for most of us is at night when it is dark and there is little to no light. If a camera performs at night, it is easier to tweak settings to make it work during the day than it is the other way around.
Did I mention avoid Reolink, especially at night they are horrible. Look at these examples.
What you mean a missing hand isn't normal LOL

(plus look at the blur on the face and he is barely moving and this should be ideal indoor IR bounce and it struggles):
How about missing everything but the head and upper torso
The invisible man, where can he be. Thank goodness he is carrying around a reflective plate to see where he is LOL (
hint - the person is literally in the middle of the image at the end of the fence)
I've seen better images on an episode of ghost hunters
And of course, this is an example from Reolink's marketing videos - do you see a person in this picture...yes, there is a person in this picture.... Could this provide anything useful for the police other than the date and time something happened? Would this protect your store? The still picture looks great though except for the person and the blur of the vehicle... Will give you a hint - the person is in between the two visible columns:
Bad Boys

When the cameras can't see you
Here is the unofficial Reolink page where people have provided their best nighttime image captures. As you will see, they are basically useless.
Executive Summary: DO NOT be a sheep. Ask what a reviewer can be missing, ask if a reviewer is using hype words to sell the cheapest product. Test your cameras and kits right away. Just do a bench test. Test real world conditions. Test moving suspects. Test at night, test at day. Use a test rig...
