Review: Great - Works perfect, out of 500 motions it needed to detect, it was 499/500 ( from what I noticed), it’s the best for the price
Review: So this helped me a LOT within the first week - We purchased this because we needed to keep track of our dog who has started wandering off when not let inside ASAP. I wrongly assumed that one or both of these would be plug-in but that’s not the case. That’s not a dealbreaker thought. It’s only been a week so I can’t speak to battery life, but the sound options are varied and the volume is adjustable. It hasn’t been annoying. It is really nice to have a little peace of mind that I’ll have an extra reminder when my dog wants in (or turns around to leave) I haven’t used the sticker portion yet because I want to make sure it won’t be annoying. I positioned it temporarily on our back deck actually by propping it on a stick (seen toward the bottom of the planter in my pic). So far it has very few false positives, although due to wind there have been a couple. It’s due to a grill tarp, so changing the angle will resolve it. We have a few other security items that send notifications directly to my phone and can have false positives. They also have a LOT of false negatives. Last night at around 2 am, a man walked past three of my smart home cameras and only one of them sent a notification, and even then I assumed it was leaves blowing around. However, a man then walked on our porch and started trying to get into our house! He tripped the motion detector and it made a doorbell sound just as intended. it woke me out of my slumber stupor enough to take it seriously. My fiancé and I started checking our cameras and realized that he had been looking for hidden keys, then went to the front porch to do the same, had a sit there for a while, then went to the neighbors porch. (Long story short, we live in a very busy area; the police came quickly and it turns out he was intoxicated and thought he was staying here. We opted to not press charges and they gave him a ride to his real destination). we likely would have slept through the whole thing if we didn’t have multiple forms of alerts. And in this one instance, it was actually better for this guy that he was escorted to his warm bed instead of distraught on our patio. I’m thankful that we not only were alerted but got answers quickly. I may get a second one for our front porch

### ⭐⭐⭐⭐ Works as advertised, but...
*by O***S on September 9, 2024*

Got the single sensor with 2 receivers. The first receiver is about 40 feet from the sensor (which is outside but sheltered from the rain and sun), but inside the building. It works perfectly. The second receiver is about 150-200 feet from the sensor. It is also outside but under cover. I had it slightly around a corner of the building and it didn't work. I had to move it from behind the building so it had a direct unimpeded path between the receiver and sensor and it works fine. It just isn't exactly where I need it. I decided I didn't want to have to keep changing batteries and worrying about the batteries dying, so I plugged them in using the USB ports. By the time I bought 3 USB cables and 3 adapters, it added another $60 to the price, so figure on that or having to buy batteries for the life of the door alarm system (takes AA and AAA batteries, not included).
