Go smash your hand with your biggest hammer. It will cause less pain then the Amcrest setup.
To the OP- the 兎asiest cameras work with WiFi. Once you get good WiFi to the areas that you want cameras their are several choices. I tried several that didn稚 work as advertised. I settled on the iSmart cameras. They are indoor cameras but I can look through the windows.
I have AmCrest. At first, I loved it. Very nice out-of-the-box setup and kit included 2 real long + 2 60' cables so nothing extra needed to buy (except monitor, but had an old one to re-purpose). Setup was super easy and just downloading their app from google playstore then scanning the QR code on box had it working on my phone. 100x easier setting everything up and having it running than I thought it would be. Very good picture quality for inexpensive cameras on BNC cable. Included HDD holds about a week's worth of 4 cameras recording 24/7 (not using motion detect).
Then the box started to make a racket. Investigate and the fan was chewing into its housing. Was an odd size like 50mm (can't remember exactly) but had to special order since none of the typical PC sized fans I had in pile of old computer junk were right. But simple fix.
Then one camera started only working intermittently. Then barely, then not at all. Turns out it is the connection at the box. Something wrong there that I figured was a broken solder I could easily fix, but no luck figuring it out. Wiggling that connection makes the camera work. But otherwise, it just displays black. No idea what caused tat to fail - not like I move the box around and once set up, never moved the cables around. No stress on the cables pulling on that connection.
So I went from an AmCrest fan to "never again"....oddly that change in attitude toward the brand happened right after warranty was up

That's as long as it worked right.
But we did have some people going through neighborhood breaking into cars and was able to give local PD a thumbrive with excellent HD pictures of their faces. So although some problems and it only 75% works after a couple years, when I did need recorded footage from it, it was there and fairly easy to retrieve and download.
The phone app.....when it works, its great. Only works half the time though. Might be the app, the system, my phone, or my wireless router. No idea why it sometimes chooses to work or not work. But is kinda cool to be away from home and see everything at the house.
For my remote property (no utilities, no internet), I use Moultrie A30i trail cameras. Not the best cameras, but I like the Moultrie steel lock boxes that fit those that can be secured with a Python cable, regular padlock, or both. The "i" versions (A-30i, A-40i, etc) don't have red glowing lights at night so don't give themselves away. They work pretty well and i just have several scattered but overlooking each other along with watching their designated areas. For that application, I'm pretty happy with their performance. No sensitivity setting so LOTS of pictures of tree branches blowing in the wind, but that's only complaint. Great pic quality even at night and last a long time on the inexpensive Amazon Basic brand AA batteries.
