All the Lorex systems I see have 4/8 cameras. Do they sell 2 camera systems?
Online you get about 43% off on a lot of systems. I get the impression this equipment has a low cost .. and so 2 or 4 doesn't make much difference to them. They are good at replacing defective equipment and I recommend a 5 year extended warranty. So, to answer your question - 4 cameras is probably what makes sense. Here is one on sale, although it only has 1Terabyte of storage - you should probably have them upgrade it to 2T or more:

Once you get used to these, they are kind of nice. There is a bit of a learning curve. My office is upstairs in the back part of the house - and with the cameras, I always know what is going on in front - and don't have to go downstairs to find out.
1. The power to the cameras goes through the ethernet connection. So, you want to have the camera ethernet connected directly to the Lorex DVR or to an intermediate PoE switch (PoE switches deliver power as well as provide for the internet connection). So, if there is a large distance between the camera and the DVR, it may look like Camera ---- PoE Switch --- Router ---- Lorex DVR.
2. Using DHCP, IPs will be assigned to each Camera and to the DVR.
3. You will have to get some practice setting things up with the DVR, your computer, iPhone and optionally the cloud. Your computer and iPhone connect to the DVR via the cloud, yet cloud storage is separate from DVR storage. If you have a 2T DVR and 2 cameras you can store 3 weeks data. But you can plug in an auxiliary disk (say 12T if you have the money) and backup from the DVR to the storage.
4. Sometimes you need to take the cover off the camera and reset it. So, if you put it on top of a flagpole or your chimney - understand you may need to get to it once every two years or so.
