My standard welcome to the forum message.
Read Study Plan before spending money
Cameras are for surveillance to get information for after the fact.
Please read the IP Cam Talk Cliff Notes and other items in the IP Cam Talk Wiki. (read on a real computer, not a phone). The wiki is in the blue bar at the top of the page.
Read How to Secure Your Network (Don't Get Hacked!) in the wiki also.
Quick start
1) If you do not have a wired monitored alarm system, get that first
2) Use Dahua starlight cameras or Hikvision darkfighter cameras if you need good low light cameras.
3) Start with a good variable focus camera, so you test for the correct lens,lighting, camera placement.
4) use a VPN to access home network (openVPN)
5) Do not use WIFI cameras.
6) Do not use cloud storage
7) Do Not use uPNP, P2P, QR, do not open ports,
8) More megapixel is not necessarily better.
9) Avoid chinese hacked cameras (most ebay, amazon, aliexpress cameras(not all, but most))
10) Do not use reolink, ring, nest, Arlo, Vivint cameras (they are junk), no cloud cameras
11) If possible use a turret camera , bullet collect spiders, dome collect dirt and reflect light (IR)
12) Use only solid copper, AWG 23 or 24 ethernet wire. , no CCA (Copper Clad Aluminum)
13) use a test mount to verify the camera mount location. My test rig: rev.2
14) (Looney2ns)If you want to be able to ID faces, don't mount cams higher than 7ft. You want to know who did it, not just what happened.
15) Use a router that has openVPN built in (Most ASUS, Some NetGear....)
16) camera placement use the calculator... IPVM Camera Calculator
17) POE list PoE Switch Suggestion List
18) Camera Sensor size, bigger is general better Sensor Size Chart
19) Camera lens size the bigger number the more range the less FOV. . Which Security Camera Lens Size Should I Buy?
20) verify your camera placement, have a friend wearing a hoodie, ball cap and sunglasses looking down approach the house, can you identify them at night ?
21) DO NOT UPGRADE your NVR or camera unless you absolutely have a problem that needs to be fixed and known what you are doing, if you do you will turn it into a brick !!

Three rules
Rule #1 - Cameras multiply like rabbits.
Rule #2 - Cameras are more addictive than drugs.
Rule #3 - You never have enough cameras.
Quick tips -
The smaller the lux number the better the low light performance. 0.002 is better than 0.02
The smaller the "F" of the lens the better the low light performance. F1.4 is better than F1.8
The larger the sensor the better the low light performance. 1/1.8" is better (bigger) than 1/2.7"
The higher the megapixels for the same size sensor the worse the low light performance. A 4MP camera with a 1/1.8" sensor will perform better than a 8MP camera with that same 1/1.8" sensor.
Remember these sizes are fractions. Do the math!
@ SouthernYankee - Very true regarding your comments about plan before spending money. I didn't realize that before buying a system that didn't fit my needs. So I had to return it.
@ sebastiantombs - haha...very true rules! I'm starting to see that now. Before joining this forum, I thought spending more than $300 on 1 camera is outrageous. After reading through some of the threads, $300 per camera doesn't sound bad as long as it fits your needs (being able to ID people/plates, etc.). I'm still a bit fuzzy on sensor size...so...will be reading up on that.
Thanks all!

The short guide to sensor sizes.
2MP needs a 1/2.8" sensor for good low light performance.
4MP needs a 1/1.8" sensor for good low light performance.
8MP needs a 1/1.2" sensor for good low light performance.
An 4MP camera on a 1/2.8" sensor will need twice as much light as a 2MP with that same sensor.
An 8MP camera on a 1/2.8" sensor will need four times as much light as a 2MP with that same sensor.
An 8MP camera on a 1/1.8" sensor will need twice as much light as a 4MP on that same sensor.
Every camera, other than a true infrared camera needs light to see in "the dark". Starlight, Starlight+, ColorVue, FullColor and such are nothing more than marketing terms.

Now that I’ve been here a year. I think I know stuff. But I still have a lot to learn.
They keep telling me to read stuff. I just click on settings and see what happens. Then I read how I was supposed to do it.

Oh man. You don't know how helpful this is for me (and I'm sure for many). Thank you for putting it in simple and to-the-point terms. Stuff I've read online isn't as helpful as this.

Plus sensor sizing can confuse a lot of people LOL.
Is a 1/2.8" sensor bigger than a 1/1.8" sensor? Most people say yes LOL. But it is a fraction, so the 1/1.8" sensor is the bigger of the two.
This applies to camera sensors too LOL:

1/3" = .333"
1/2.8" = .357" (think a .38 caliber bullet)
1/1.8" = .555" (bigger than a .50 caliber bullet or ball)
1/1.2" = .833" (bigger than a 20mm chain gun round)
1/2.8" = .357" (think a .38 caliber bullet)
