I have Arlo wireless cameras around my property. I was initially 100% pleased with them. Very easy to install and set up. They are more expensive than other cameras but you pay a premium for not having to run wires. They do not record 24/7 like DVR-based setups; they have a motion detector which activates the recording and the recordings are saved to "the cloud." There are positives and negatives to this. If you arrive to find your building burnt to the ground, the video on the DVR will be unrecoverable and you'll never know who/what started the fire. On the flip-side, the motion detection isn't perfect and if you arrive to find your building broken into and things stolen, there is a slight chance that the burglar may not have tripped the motion detector, and there won't be any continuous footage stored for you to manually sift through and find the perpetrator.
I was aware of the limitations of the wireless camera system when I bought it, and for what it is and what I paid for it, I was happy. But as time went on I became less satisfied. One of my cameras randomly stopped detecting motion. The one on my barn which is right next to the door to capture the face of anyone who approaches it. You could walk right up to the door, standing right in front of the camera, and maybe it would record you, maybe not. Previously is had been hit-or-miss only if, for example, there was a house cat crossing its path at 30ft away. Now it's hit-or-miss with the center mass of a grown man 3ft away. After about a year, the battery life started to decline. I noted when I first bought them, how amazing it was that they could remain charged for over a month, with dozens of recorded events each day. Now what used to last a month lasts a week.
Knowing what I know now, might still buy Arlo cameras, just because of the labor required to install anything else. But if you had asked me last year it would have been a resounding recommendation. They are so, so easy to install, and if you don't plan on having a lot of traffic in front of the cameras which will strain the batteries, then it's probably a good choice.
