Motion Sensor Alarm System, Wireless Home Security Driveway Alarm Indoor, Motion Detector Alert with 2 Sensor and 1 Receiver -38 Chime Tunes

Works great!!

They are amazing and easy to use and loud enough to hear. The motion detection is to sensitive because air and bugs trigger it and at times leaves falling and I believe shadows to. Appearance is great and the flashing blue light at night is good, battery life so far is good but definitely infest in AAA batteries because you will need them due to they are not included. Definitely good for knowing when anything Like bugs, air, shadows, nothing shows up on your property.

This is a very good driveway alarm. Over a year already and I still haven’t replaced the batteries. I put one receiver in the house and the other in my shop. We live in a rural area and it’s nice to know when a delivery comes or an unexpected guest. The range is good even with our aluminum siding.

Se lo recomiendo. Para ponerle stop. A los rateros

No customer support. Receiver that plugs into the wall is completely dead. No lights no sound. I have other units in the house that are working and yes the receptacle has 120vac. The troubleshooting support is a joke. I can't find anywhere to get answers to the problem

Simple plug and play install. Decently loud if you choose max sound option. I don't quite believe sensors range 328ft as said. I'm getting 35ft a sensor, and I noticed at night the sensors they illuminate blue on edges when they pick something up. They put a crazy amount of alert notification songs. I chose door bell sound because it's the shortest. The rest are tunes of jingle bells and songs like that, but they feel long and if sensor sends alert again it restarts the song. They work well, but I don't think distance they sense is accurate. I'm not disappointed with product so far 2 days use and it's working.

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.

Make sure you have a clear path when you mount the unit. If you tree branches within view, it will give false alarm when the blows. Also, you must mount unit in a place that is protected against exposure to the sun and rain. Other than that the unit is great for the price.

These work very well. They pick up movement as small as a bird flying by.. My partner purchased these after someone entered our property to check unlocked car doors at night. Now, every time a cat, racoon, or the wind blows hard, my house fills with the sounds of a grandfather clock and someone yelling in Chinese (mandarin?)..I'm no dialect expert. Although I'm not pleased being woken up at 2 am by a raccoon, I can't deny these work extremely well.

I think they are great for the cost!!! Yes, they may be set off by a fly, cat, bird, but that's to be expected I think. Three make different noises, so I know where customers are as they come around the building.
