We have a long driveway and I have the unit approximately 300 feet from the house and it works without any issues at all

This unit is much easier to hear for those of us that are told we are deaf by our wives.

Dear Sirs,The indoor unit is fine and worked well while the outdoor sensor that came with the unit and the additional sensor I purchased both worked

One was more expensive but lasted no longer than cheap units

This unit is consistent and has not failed to work.

I definitely recommend this unit.

We tried one of the cheaper unit and had several false alarms, This unit is rock solid.

The unit is a bit bulky from what I was expecting.

Love the unit we have a 250' driveway and put the receiver in the living

I place mine about 250 feet from receiver, great reception, it works fine, car, bike, kids and my dog will trigger the sound, we just started Fall so a few leaves will also start the unit but not as much

the unit is line of sight about 60 feet from receiver and still wont work

We live in the country and other than picking up deer (I'm assuming those are the rare false alarms), the unit appears to ignore the squirrels and rabbits

Well the unit is very customizable but the range is not even close to the advertised range

The unit does alarm when deer walk across our driveway, but that's not a problem as we like to see them

After messing with a cheap driveway alarm from Harbor Freight, this unit seems like a dream

Very good unit

The unit is well within the distance for receiving signal and has a clear line-of-sight, but does not work consistently.

Nice unit.

Excellent unit overall - the directions for setting the desired DIP Switch (color of switches are white) settings, located inside the rear of the sensor were unclear.

unit is easy to change the volume, change the ring tone or to turn the unit off

The unit is well within the distance for receiving signal and has a clear line-of-sight, but does not work consistently.

This unit was more expensive but well worth it

Very good unit which we highly recommend.

For me, overall a good unit, but could be made a lot better with a few simple changes.

I tested the unit myself and it worked exactly as advertised

Sound is good form the unit, but day of the Internet, now that's different

One unit stopped working

I still love this unit and recommend it so far

This unit is rock solid

It's a neat little unit,

We have gone through 3 cheaper units, as we have a business in our

Other units claim to work at long distances, but fail to deliver

I've had sensors (Mighty Mule, two different units) that will only pick up vehicles, as they are designed

This unit works as advertised

Unit works well and has good features

this unit works very well for my purpose

unit stopped working after first heavy rain.

We don't have false alarms and the unit reliably chimes when anyone passes by in their car, or even walking

so the unit will not trip if you are working out in the covered zones

Returned the unit after it failed to operate consistently at 100' nevermind 1000'

Overall a great unit.

Other units claim to work at long distances, but fail to deliver

so when the wind blows sometimes I get a false alarm when branches swing around, (may trim the tree to fix that if it get's too annoying) but otherwise this unit is perfect for my needs

Good unit

The units still worked, but changing batteries was fun with the ants inside

One month later and still no response so have trashed this unit and bought another vendors product that comes with two sensors and one third the price

Yes, we would recommend these sensing units to our family and friends.

Customer support said they would replace the defective unit

Love this unit, just wished Amazon offered upgrades like more sensors on website with prime shipping.

I use it at bedtime 10pm to 530am because I have alot of kid traffic during the day and this unit can be set only to work at night.

The unit is easy to set up and works quite well.

Very unreliable unit

advertisement says the unit is very reliable and has a 500 Ft range

My unit was running on battery power ( unknown to me) even though I was plugged into AC power

Great unit if you don't mind it only working about 1 in every 5 times an automobile passes the sensor

Based on two week’s usage, I highly recommend this unit thus far and here is my pros, cons, & discoveries after a few weeks of usage

I have purchased much more expensive units that do not work as well

So, these aren’t bad units but do keep in mind you might encounter the same sensitivity range limitations as I did.***I continued to experiment with the

To make matters worse, when there was actual traffic in the driveway, the unit failed to alarm most of the time

We tried one of the cheaper unit and had several false alarms, This unit is rock solid.

Messed around with cheap units which were always giving false alerts or no alerts at all so decided to spend the money on Guardline

Unit has only been in a few days but works great!Easy to install, too!

It's a great unit

But a very solid unit.

Fantastic unit.

Unit works great

They appear to be very well made units, and they have many user adjustable features, whereas the old system had almost none

Excellent unit

I've had the unit a couple of weeks and I highly recommend this system if you are in the market for a driveway alarm.....

Unit works very well as advertised.

I suspect cheaper, competitive units listed on Amazon work as well or better.1)

Great unit - especially the dry contacts.

but that's how good these units are

I suspect cheaper, competitive units listed on Amazon work as well or better.1)

A second problem was the unit sometimes would not pick up motion until a person was six feet away; other times it alerted to someone 12 feet away and several times when 35 feet from the sensor

LIKE; The alarm functions much better than the cheaper unit I had previously

"Dave" at Guardline emailed back a list of suggestions I should try and if those didn't work, he said Guardline would exchange my unit, and if that didn't work, they would refund my money.

I emailed the company from their website, and was told that my unit is not defective, is operating as they designed it, and is designed "for driveways".

an outstanding unit and in every way i would rec commend it to anyone that actually wants a gate alarm

I have only had the unit up and working for a week, but it tells me when the mailman comes, tells me when UPS delivers my many Amazon packages, and does exactly the job I need it to do.

Great sounds options to choose, only one unit ,but nice to know I can add more zones to it, one week on and no problems

Unit work for a couple days and quit working

Hopefully I just got a bad unit and everyone else gets a good working one.

Our Dad is fairly hard of hearing, and he could not hear other similar devices we tried, when his 20 year old unit went kaput.

This unit is way overpriced.

I used a cheaper unit - Bunker Hill for three years and never had these issues

Unit is working nicely

We got this in July, we went off the reviews and spent the money for what we hoped would be a good long lasting unit

I am hoping this unit will be good for the long haul

Returned picked u falling leaves and birds..

well i just left it.he told me to reposition it, still the same

n’t had any false alarms from bugs, animals, ect

n’t work
