I have the Arlo completely wireless system....no need to locate by an outlet or wire to control base. I can take them with me if I move and they can be changed easily to another location that I want to monitor (just pick it up and move it). One drawback is replacing batters every few months- which I buy at Amazon.
Arlo is made by Netgear and available at Sam's. Up to five cameras have free cloud storage..no monthly repeating charges.
Recordings are kept in the cloud for one week before elimination.Easy to download any videos that you want to keep permanently on your phone or PC. Cameras are totally weatherproof and very easy to set up. You can even mount to a tree.
I have two outside and two inside. The inside ones are off unless I leave the house, and then I just flick them on with my iPhone.
Many options such as recording length, sensivity, and video quality are easily adjusted. Has night vision.
Short lag time when camera is activated so the one by the front door allows me to know who is there when the door bell rings.
Arlo makes a more expensive unit called the pro with rechargeable batteries,, voice and siren. They also make a wired one.

All their units work off the same base. If a camera is activated, I get an email or text within a couple of seconds and can watch activity.
Simple, relatively cheap, no monitoring costs, good quality video, no wires whatsoever to run, except connecting base to router a foot away. More than five cameras require paid cloud storage.
Been please so far.
