Yes that is the beauty of IP cameras is you have so many opportunities. You can run all the wires back to the NVR or run them to switches and one cable back to the NVR.
In that instance, you would want to get a non-POE NVR.
Now for a word of caution.
I started with four 2.8mm cameras and I was like "I can place one on each corner of the house and see my whole property and the whole neighborhood." A newbie loves the wide angle "I can see the whole neighborhood" of the 2.8mm fixed wide angle lens. I LOVED IT WHEN I PUT IT UP. I could see everything that would be blocked looking out the windows.
It is easy to get lured in to thinking the wide angle "see the whole neighborhood" because you are watching it and you see a neighbor go by and you are like "Look at that I can tell that is Heather out walking." and "Yeah I can tell our neighbor 4 down just passed by". Or you watch back the video of you walking around and are like "yeah I can tell that is me".
Little do we realize how much WE can identify a known person just by hair style, clothing, walking pace, gait, etc.
Then one day the door checker comes by. Total stranger. Totally useless video other than what time the door checking happened. I was so furious my system let me down.
Then you realize that this wide-angle see the whole neighborhood comes at a cost and that cost is not being able to IDENTIFY who did it. These 2.8mm wide angle cameras are great overview cameras or to IDENTIFY someone within 10 feet of the camera if the camera is installed less than 9 feet hight. At 40 feet out or a higher install you need a different camera.
And like most, I stuck these wide angle cameras on the 2nd story to be able to see even more, which then means any IDENTIFY distance is lost vertically. Someone needs to be within 10-13 feet to identify someone with a 2.8mm lens. A camera placed 16-20 feet up means the entire IDENTIFY distance is lost in the vertical direction. They could be one foot away horizontally, but at 20 feet high, you will only get a good shot at the top of the head...
So then we start adding more cameras and varifocal cameras so that we can optically zoom in to pinch points and other areas of interest to get the clean IDENTIFY captures of someone. While the varifocals are great at helping to identify at a distance, they come at a cost of a reduced field of view, just like the wide-angles are great at seeing a wide area, but they come at the expense of IDENTIFY at distance.
Long story short - you will end up wanting more than 4 cameras, so go with 8 or 16 channel NVR.
Most of us ended up like this guy that posted just today LOL:
I had a kit system from Reolink (thanks to youtube reviews before finding this site). One year ago I needed to review material from some days. It turned out to be hard to find the correct event (no human/vehicle detection) and after finding it, the material was basically useless for even...
