Guardline 500 Foot Range Wireless Driveway Alarm [1 Motion Detector Alarm Sensor & 1 Receiver] Weatherproof Outdoor Security Alert System for Home & Property

First I'd like to give Guardline 2 thumbs up for packaging. Very professional with a user manual and a quick start guide.The manual is well written with pictures to show the switches and what they do. Well done.Setup was easy and it works perfect.The sensor is made out of some kind of plastic. Since it is not going to be under any stress so it should last a long time.The receiver is made out of heavier plastic and blends into the environment well even though its mostly black with silver. The base is designed so it is easily seen across the room. Large numbers so you can tell what zone is on even from another room.Comes with ac adapter. Wish other manufactures did the same instead as an accessory. You do need to provide 4 AAA and 4 AA batteries.Couple of things I wish it did...1. Turn off the red light on the sensor. You can have it on for testing but be able to turn it off after it is installed so it is less noticeable.2. The zone light only lights when the melody is playing. I wish it would stay on so that when I return to the house I can see if it was activated. It does offer NO and NC contacts so I could add an external led light but I haven't tried that yet and don't know if the contacts operate as the zone light does. I'll have to play with that.There are online videos on just about every procedure if you need the extra help. Nice feature.I use mine for mostly delivery alerts so I can get the packaged out of sight as soon as possible. Also to alert me when some door banger selling something comes to the door.I have mine about 7 feet high and about 10 feet from the door. The tilt on the sensor was easy to adjust for that angle and distance.Overall it is a great product. I hope I get many years out of it and possibly add a couple more sensors later.Hope this helps.

This is an augmentation to my original review below which at the time I had rated this product at four stars. I changed the rating to five stars because in the time I had it, it worked quite well and then when I had a problem four years later I was very satisfied with their customer service.I purchased this item in December 2016. The item worked quite well and I was quite satisfied with it. There was an occasional false alarm which I think is to be expected. More than once when I looked in my driveway there was either a squirrel or a crow that had set it off.In August 2020 the sensor started acting up. It kept going off every few seconds. I followed the troubleshooting section in the instructions to no avail. At the bottom of the manual there was an email address for more information. I sent a note to Guardline asking for help in fixing my alarm. They replied they were going to send me another sensor. I wrote back and told them this unit was not new and that I purchased it about four years ago. They wrote back and told me they shipped me another sensor anyway. Now, you can't beat that for customer service.==============Original Review==============I just finished installing this product so I cannot yet comment on the reliability it. I will give my initial impression. This is more expensive than most of the other alarms. I purchased it because of the high ratings in the product reviews.The sensor housing looks cheap. That doesn't mean it won't be reliable but I would expect better cosmetics for the hundred dollars I paid for it. My biggest objection is the ball joint that is used to aim the sensor. It is far too loose. I received and e-mail from the vendor that sold it to me about the time it was delivered telling me about the product. In it, it had this sentence: "If your sensor doesn't stay pointed in the direction that you aim it or the ball joint is loose, you can easily fix this by tightening the screw located on the back of the mounting plate." This is not true. I tightened it as much as I could and it still was loose. I suppose one could put a drop of glue on the ball joint to keep it in place but that should not have to be necessary.The instructions were a little hard to follow and there were a few minor mistakes in them. For example, it said see section "G" to set some of the advanced features. The settings were described in section "I." Also the instructions showed three sets of four DIP switches each set of switches labeled 1 to 4 to set the advanced features whereby on the unit there was one set of 12 DIP switches numbered 1-12. Most people wouldn't be changing these advanced features anyway (I didn't) but, like I said, it was somewhat hard to follow.In Amazon's product description it says, "4 “zones” allowing up to 12 sensors per zone." But according to the instructions there can be no more than 4 sensors per zone,16 total. But even that seems to me more sensors than I can imagine anyone using.There are plenty of melodies to choose from - 32 in all. A different melody can be set for each zone so one doesn't have to look at the sensor to know what zone has been tripped if one learns what melodies go with what zones.
