Is it hard to install?

Asked by: Martha
This hardest thing about installation was just digging the 1ft deep trench to bury the cord and receiver in the ground. We had it installed in about 15 min.

Since this is wireless, do you need Internet for this to work?

Asked by: Ah
No. The connection is between the receiver and transmitter only. It uses its own code/frequency.

Wireless Driveway Alarm is rated 3.8 out of 5 by 261.
Rated 5 out of 5 by from Works great, long range, long battery life I bought this a year ago and immediately installed it. Using the manufacturer's specs, I wasn't hopeful that it would work near the end of our drive -- about 350 feet but direct line of sight. I installed the sensor very shallow, about 2-3" deep right next to the driveway. I zip tied the transmitter to a shrub as high as possible. I am on the original set of batteries (Duracell) and it has been working very well. It has not gone off maybe once or twice. We live on the end of a cul-de-sac and if someone swings wide close to our driveway when turning around, we sometimes get an alert. My wife was very skeptical at first but now she loves it. Very happy with it. Now I am about to hack into it and run the beeper leads to a Wemo Maker so we can automate it. Should be a fun experiment with home automation.

At maximum volume it cannot be heard well in adjoining rooms. If a TV is on or people talking, it cannot be readily heard or recognized. Additional receivers at $42+ are needed for this to be a functional alert system. Compared to other driveway alerts that actually sound a distinct chime easily recognized, the volumn and ping sound on this unit (certainly for the price) is absolutely unacceptable.

Rated 5 out of 5 by from Wireless Driveway Alarm! Love it! This was so easy to install! Works perfect. Wished I would have bought one of these years ago. I highly recommend this alarm.

Rated 5 out of 5 by from Very Effective Driveway Alarm When you live back in the woods, it can be scary to hear a surprise knock at your door when you are not expecting company. Now that I have this driveway alarm, I can be alerted when they pull up and be ready for them before they even get to the door which is awesome! The sensor it about 150ft. away from the house and has worked 100% of the time (that I know of) with no false positives. The only thing that I would recommend changing about this product is that the alarm is not a pleasant sound. It sounds a bit like a smoke alarm and would be nice if there was a setting for a nice chime similar to a door bell.

Rated 5 out of 5 by from Drive way alert easy to install, takes a few minutes with a shovel. not sure how long the AAA batteries will last. No false alarms, will pick up riding mower to large delivery truck. easily turned on/off whenever necessary. inside house. Follow directions.. TEST BEFORE YOU BURY UNIT.. am in the country so no danger of picking up neighbors and am way off highway. You can turn up/down sensitivity (outside sending unit) and volume up/down from receiver inside house . So far great investment. This is much better than the infrared sensors, had nothing but trouble with those.

Rated 1 out of 5 by from Cable is WAY too short!!! Not cool that the cable between the transmitor and magnet is so short that the transmitor has to be right in the grass. Have to mow around it because it won't reach over to any shrub or post.

I feel better now that my wife and daughter are alerted when someone drives up. we have had it about a month and we are very pleased with it. the only drawback that I experienced is the cable that connects the sensor with the transmitter is not long enough for placing it in my preferred location.

Rated 4 out of 5 by from Great gate alarm The alarm was easy to install, works like I expected. It detects large metal objects like cars and does not respond to things like animals, birds or blowing leaves. I purchased this one as a replacement for one we've been using for three years. The transmitter stopped working. Possibly due to the excessive rain we've been experiencing. We used the full extender poles provided with it this time to lift it higher off the ground.
