I just installed new cameras on my house. I previously had a Lorex system from Costco but this new system (AvertX) is far superior (also from Costco but only available online). It is very clear and I could read a license plate from 100 ft. The night vision is really good too. It came with an 8TB NVR which is probably needed for a 4k system. It stores about 2 months of footage and then overrides itself.
From all the research I did, wired is better and wireless is never really wireless since most cameras need a power source). The better your system is (ie.., 4k, etc), the more power they require.
With the modern 4k and digital setup, the wiring is a Cat5 wire vs the 1080p systems which use an older setup that has two separate wires (power and data).
My setup uses dome cameras (it came with 8) and they are considered better as they are hard to tell which direction the camera is pointed, harder for a thief to pull off the house, have break resistant domes and you would have a hard time breaking with a baseball bat). I added two bullet cameras for a total of 10 cameras and I went with bullet due to mounting issues). I also put one of the domes in my built-in book case in my living room which gives me a general view of my home from inside without ruining anyone's privacy). It took me a week to install as I did two cameras a night and climbing thru the attic was time consuming.
I really like my new setup. I can view the cameras from my computer at work or any computer. I can also view on my phone using an app that you download. I installed the NVR recorder in my regular stereo cabinet so it is direct wired to my TV and I can view on the TV anytime.
