I’ve had expensive systems in the past and the Ring system is just as good or better for a fraction of the price. The sensor works as expected and has two settings...one is less sensitive if you have small pets moving around. The sensors are quite easy to setup.

FIrst of all, I love the Ring security system. Its much less expensive than a system installed by, say ADT. The motion sensors work great. You can create zones or utilize it as an entry monitor. Easy to use, zero problems so far.

The installation and setup was simple: drill (or stick with included command strips) the bracket to the wall, pull the tab that sits on the battery off, and stick the detector on the bracket. The motion detector connected to the alarm base via the app within seconds, and was up and running. The motion detection has been excellent. It practically always catches motion when we walk through the space it monitors, but doesn’t seem to have trouble ignoring the cats. That said, just two issues to touch on. First, because it is so good at catching motion I worry the battery may not last long. You can decrease the sensitivity but it still seems to note motion every time we enter the room. Second, and tangential to that issue, there is no turning it off. Even when the alarm is disarmed the app still shows it is recording motion events. This makes me slightly disappointed as I figure it will continue draining the battery when we have no need for it to be monitoring. Overall very happy with it and I will continue to be so unless we end up constantly needing new batteries.

They do what they are supposed to. No false alarms. Triggers when movement. The sensors are not very sensitive. I have found that the range is not as wide as other motion sensors that I was previously familiar with. I needed 2 so the two-pack was relevant albeit no discount benefit for buying the multi-pack.

Great, very sensitive battery-powered units. Bought them on sale, and very happy with the quality and ease of setup.
