Motion Sensor Alarm,Wireless Driveway Alarm Indoor Home Security Business Detector Alert System -Monitor&Protect Property - 2 Receiver and 3 PIR Sensor-38 Chime Tunes

Good range and was perfect for what was need it.

Note they are battery operated, and they do have micro USB slot for AC power, I think, I never tested them. The detection angle is very wide and very sensitive. For my purposes, I ended up blocking part of the detector to shorten the range and sensitive.I use them to setup a detection zone in front of my house. Mainly used for package deliveries. There are so many they deliver packages but don't ring bell. Well, now they don't have to...

Good

Information is not disclosed in the description whether all the sensors work independent of each other or as one. If you think you’re going to put one sensor by your doorway, another one at your gate, and maybe another one by your driveway and then get notified of which area the movement is detected, think again! No matter what sensor detects motion you get the same exact alarm! If you hear the alarm then you don’t know whether it was the gate, the doorway, or the driveway. All you know is that motion was detected at one of three locations! So if you want to run around to all the places motion was detected to figure out where it came from, then by all means purchase this product. If you look at other multi pack motion sensor devices for sale, they will disclose whether or not their devices work independently. Inferior products will not have this feature of working independently, but the seller should disclose that to reduce confusion or disappointment.Also, the description states that it has 38 different sounds to choose from. This product was obviously intended for the Asian market. Many of the “sounds” also contain loud voices which appear to be saying things in Chinese or similar. I have no idea what they are saying. Hopefully it’s something pleasant.And the directions, as usual, lack a lot to be desired. And be prepared to get your magnifying glass out. It can’t be because paper and ink is so expensive. The outside box is glossy and full of pictures and print, but the paper is small and the letters very fine print. When someone figures out why Asian markets do that, please let me know. And absolutely NOWHERE in the instructions do they tell you how to get to the battery compartment. There are no screws to hint at perhaps the battery location. There are no stickers. There are no markings on the device that state where the batteries are, or even an arrow indicating that you have to forcefully slide a nondescript compartment (not on the outside but deep inside the device ) from below these 4 tiny plastic notches (without breaking it), and THEN lift that compartment out, and then open the cover of that compartment to expose the area that would house the batteries! Geez! Why not add that important information to the substandard instructions that are enclosed?I was very aggravated and disappointed with this product — especially of the fact that these sensors cannot independently notify you of which sensor detected the motion (you get the same exact “alarm” no matter which sensor goes off). I couldn’t get to my Amazon app fast enough, to request a refund. To Seller: At lease disclose the full capabilities, or shortcomings, of this device, so the customer can make a qualifying decision on whether they want to purchase this device or not. What a waste of my time!Update (months later): The Seller is obviously not concerned about complaints or receiving 1 Star. The seller never reached out to me. The seller has obviously made no attempt to enhance or modify their description to serve customers better, by disclosing pertinent information. I think that speaks volumes.

We bought this for my 90 year old father in-law. His hearing is not to good. He wanted to know when his meals on wheels arriving or the neighbor was coming over to check on him. He is thrilled with it, it's loud and visual light going on. Perfect for what he needs

The media could not be loaded. I will say that this will do the job of having motion sensors that alert you to movement, and is a fair price. However!With that said, everything about this feels so cheap, lightweight and like it would break from 1ft height. The sensor only went about 10ft out before not detecting motion, and it captures a rather large angle which might be what you want. But even the slightest movement set the sensor off. I don't want non stop false triggers from a shadow or movement of a bush, especially at night while I'm sleeping. I want something more reliable so I know if someone is coming onto my property. I had to return it. I'd say it's better than having nothing, but with owning the popular owl sensor set, I'm gonna stick with that. Thought I'd try something more budget friendly, but I regret the decision. Spend the extra dollars and get something higher quality.Also, for being IP65 or whatever rating it is, is very hard to believe. No gaskets around the battery cover, the only protection is the small shield that the sensor sits in. So if you have wild rain or weather, I don't think this will stand up to it. Even the mounts felt so cheap, cheaper than dollar tree items.

Worked right out of the box. Sensors are almost too sensitive for movement so beware of anything the wind can move within 20 feet. One of my sensors is 100 yards from the house and works just fine.
