Wireless Driveway Alarm,Home Security Alarm,PIR Motion Sensor Alert System

I have them hidden around my house - amazing. They work perfectly. Scared strangers walking around our community to check out the Tornado damaged homes. My cul-de-sac never got touched (prayers) ....I recommend these to everyone. Several neighbors when the power went out - no videos. Same as me, Arlo is on my computer for video - no power-no video. But these battery operated alarms are wonderful.

Works great.

It does what's it's supposed to do and it has an annoying chime with a low and high sound setting, but it sounds the same? I really didn't care about the same sound settings just as long the motion sensor worked with the annoying dying chime.I installed it right away by the front door to alert me when my Amazon items get delivered because these "A-Holes" don't ring the doorbell or knock when they drop off my stuff so stuff do get stolen.Note, motion sensor and sound device does not work well if separated more than 20ft apart. Also, motion sensor picks up my next door neighbors so the range is good.

Bought first unit and it was 'hyperactive', often chiming five or more times an hour when there was no reason I could determine for it to go off, and this occurred day and night.Contacted manufacturer and they said to return it to Amazon because it seemed to be defective.When I returned it to Amazon (without ANY hassle at all from Amazon), I asked for an exchange/replacement of the same item. I figured everybody is entitled to an "aw shucks" boo-boo now and then.Got the replacement and within a few days, it began to send a stream of false detection alarms. Needless to say, I was not happy. Again, Amazon accepted it back with no hassle and I quickly received my requested refund, which I used to buy a different brand (with a black sensor) which so far seems to be working nicely.My thoughts even before I ordered this unit, is why have it in white? That defeats most of the incognito capabilities for surveillance.Then that red LED - why have that on the face of the sensor????Sure, it's nice to have the LED for checking the operation of the sensing unit, but if you're going to put such a bright LED in, at least put it on the rear side of the sensor so the trespassing person(s) don't see it so easily!I don't like feeling I need to say this, but my opinion of this system is that it's junk.

This is the best security sensor anyone can get for the highly reasonable cost. Easy to install and easily fades into the landscaping with little effort. Alerts you to any comings and goings approaching your house. Chime box inside the house with volume control.

Very good alert to what is outside your house. Very useful

Good little security system. Great for alerting when someone pulls in driveway.

I purchased this product to replace one that was similar. Initially, I couldn't fit the batteries into the battery compartment because the coiled wires that make contact with the battery were to long and they wouldn't compress enough for the battery to fit into the battery compartment. The contact wires are stronger but they were a little too long,I had to use a pair of wire cutters to shorten the battery contact wire to accommodate the batteries. It works perfectly fine for what my needs are. I always buy Amazon brand batteries and I've never had an issue with those batteries fitting this kind of device. Everything worked out fine and the unit is functioning properly.

The best intrusion alarm system I have ever purchased. (many). Very long driveway, activated by people/deer/couriers. Just works great! I purchased a second one for backyard, they are both synced! I like that. One Alarm for living room, one for basement "Mancave"!

Its a very helpful device but , if u go past it too fast - then it doesn't work at all.

This item senses movement well and notifies user with an audible alarm. Also a light comes on within the sensor. The sensor is battery operated and when the light comes on, it stays on depleting the battery needlessly. The only way to get the light off is to unscrew the battery cover and remove the battery. If this sensor had no light I would recommend it but as it does I strongly warn not to purchase this defective product.

When I first installed this driveway alarm, it seemed to work fine.Approx. 2 months later review. It does have some false alarms and I am positive that there isn't any wind or any cats/birds etc. crossing in the infrared path. Also noticed that when temperature drops below 0 degrees celsius, the range of the motion detection is very limited. At about 20' or less.But still better than nothing.

This alerts us when someone or something is coming into our yard.
