Guardline Wireless Driveway Alarm – 2 Motion Detector Alarm Sensors & 1 Receiver, 1/4 Mile Range, Weatherproof Outdoor Security Alert System for…

Excellent product.Used for my driveway which is about 600 feet long and surrounded by trees. I used the quarter mile version.
The first sensor I received unfortunately was defective.I called Guardline and they immediately sent me a new sensor which
I received in 2 days.This one works great. I can’t say enough about their excellent customer service.

I have a longer driveway with a steep hill and a 90 degree corner. We often had visitors and deliveryman showing up on our doorstep without warning. I needed something to give us some warning that could reach up the hill, around a corner, through a garage and into the house.

While this sensor may be a bit more expensive than others, the ease of installation and its performance justify the extra cost. I was able to install this quickly and easily (95%of my time was spent on setting a post to mount it on, but even with the post digging and setting, the whole thing took less than 40 minutes).

The unit comes set up and ready to go. Install batteries, mount to a post or tree and you’re done. You have a choice of 32 chimes to choose from and changing chimes, sensitivity and other settings is easy to accomplished. The directions are easy to follow, straightforward, and were obviously written by someone who speaks English. The diagrams are accurate, detailed and useful. I didn’t need any assistance from their technical support, but it was good to see they do their own tech support from Seattle.

Once installed, all I had to do was plug in the inside receiver (it has batteries too, if you don’t want to plug it in) and it was functioning perfectly. I have no problems with reception, despite the distance from the house (several hundred feet) the fact that it is at the bottom of a steep hill and the signal has to pass through our garage to get to the house. It works perfectly.

Now we have ample warning of vehicles or people coming up our driveway. I think I may buy another sensor and link it to this receiver so I can have a different chime when someone actually comes onto the front porch.

All-in-all, I’m very satisfied with our purchase and highly recommend this to friends, family and neighbors.

We had an in-ground magnetic wand driveway alert system before. After about a year, the thing kept going off at random moments, over and over with nothing on or near the drive. I’m not sure if it developed a short or what, but it was time to replace it. I did a lot of research. I was skeptical of the motion detector style drive-way alerts, but I kept reading good things about Guardline so I decided to try the 1/4 mile range model because we have a couple of acres with several metal buildings and such that the signal had to reach through.

There are no trees near the driveway, so I installed the motion detector unit on a wooden post about two foot tall with a solar powered address sign on it. I mounted it on the back of the post pointing diagonally up the driveway, so it can’t really be seen until you’ve driven past it. I have it set to detect up to 13 feet. It seems to work great! The only false alarm wasn’t false, it was just a very large German shepherd dog that came up the driveway. We’ve had strong winds and rain since I installed it, and nothing else has set it off except cars or people coming up the drive. I suppose a deer could trip it, but most of the deer that come through our property come up the opposite side of the front yard away from the house and outbuildings, far from the transmitter. They haven’t been detected so far.

Using the receiver in battery mode, I haven’t found a place on the property that it won’t pick up a signal from the transmitter. We have a large house, a guest house, and a 30×60 metal shop and it’ll pick up a signal behind and in every one of them with the transmitter mounted at the opposite end of the property 2 acres away. So far I give Guardline’s 1/4 mile Driveway Alert system 4 stars. My only critique is that I wish some of the 30 different tones were less silly music, dog bark and cricket sounds tones and they offered more variety in standard tones. I might have given it 5 starts with better tones. If The one tone I like is very short compared to what we were used to having on the old system and sometimes when I’m upstairs I miss it. I most likely will be purchasing an extra receiver or two for upstairs and out in the shop.

Update 12/17/2018:

We’ve had the 1/4 mile Guardline for about a month now. It works great! I recently wired a z-wave contact sensor to the NC/NO relay switches on the hub, paired with my Smartthings hub. Now every Alexa Echo in the house announces “Driveway alert! Someone is on the driveway” when the sensor is triggered. I can also have it turn on lights or other routines when the driveway sensor is activated. It’s great! No false alerts. We’ve only had the occasional deer set it off, which doesn’t count as a false alert.

Great solution for us as we live on rural land. Definitely suggest this to anyone who wants to be notified of guests or intruders! Very simple instructions to set up. Many options for the chimes/tones to distinguish individual zones. I recommend this product 100%. Only downside to this product is they don’t ship to Canada. You need to order through Amazon.com.
