Basic questions (before I make an impulsive purchase)

I got robbed recently at my home. Suddenly I am interested in security cameras.

I'm a DIY guy so this could be a fun project for me. My basic requirements are as follows:
  • 4 Cameras looking out around my yard (no inside cameras)
  • POE
  • PIR Motion alerts (Don't want alerts from bugs and trees moving)
  • Flood lights when motion is triggered

I don't know if should get an NVR, of if Blue Iris is the better option.

I have my eye on the following bundle from Lorex. (I think Lorex is a subsidiary of Dahua)

You are off to a good start.... read study plan before spending money ....

I have about half my cameras inside, covering the doors, and windows
My front door has three cameras out side.
The Garage has two cameras out side one on each side of the driveway, covering for car door checkers.
If the camera is over 7 ft up it will not id the bad guy.
Motion lights will blind some cameras at night. Motion lights are NOT a deterrent.

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) your first camera should be a good variable focus camera to check camera placement and the correct lens.
3) Use Dahua starlight cameras or Hikvision darkfighter cameras if you need good low light cameras.
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 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 V3
17) POE list PoE Switch Suggestion List
18) Camera Sensor size, bigger is general better Sensor Size Chart
19) Camera lens size, a bigger number give more range but less field of view. 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 ?
