“Mighty Mule” is an organization that provides its clients with special mechanisms for gate opening, but it is also known for many quality and affordable driveway alarm devices. By creating driveway alarms, the company successfully uses the same motion sensor technology as for gate opening.

The Mighty Mule devices are really popular among a wide range of customers. And the main reason for this fact is the absence of any false alarms. If you are searching for a motion sensor that will warn you only about any autos that come to your long driveway, then this device is really for you!

Before buying this device, you will probably ask yourself: “Why should I buy it, and why do I need it?” so now we are going to focus on the main features of the Mighty Mule driveway sensor.

Mighty Mule magnetic motion sensors

This model of driveway alarm functions due to the sensor wand, which detects the surrounding magnetic field and recognizes all metal stuff that locates nearby. If you have a will, then this sensor wand is possible to hide (up t0 12 inches deep!), so it will be almost invisible and won’t ruin the view of the Landschaft. Moreover, the cable which is connected to this sensor “wand” is totally weatherproof. So in case of any storms and nasty weather, it won’t stop working.


Another feature of this “one of the best driveway alarms” is the batteries that it uses. To turn on the device, you will need “AA” batteries (which is possible to find nearly in every supermarket). We recommend you use these lithium AA batteries for better work.

False alarm prevention

Many owners of different driveway alarms complain about false alarms cases (which can be really disturbing though). Luckily, the Mighty Mule driveway alarm has another type of sensor, so it doesn’t react to any animal or any leaves that fall from the tree. The motion detection of this sensor includes only the vehicles.

You may also think about how this system works. It is quite easy! When the auto overpasses the magnetic field (a territory where the sensor is located), then the transmitter will give a signal to a receiver, so this way you will know if there is any car traffic in your space.

An alarm receiver

If any vehicle passes by your driveway, you will get a notification about that on your indoor receiver, which is really convenient. If there is a case when you haven’t heard the sound of an alert, you will still be able to know about the danger by the LED of the receiver. It will shine until you turn it off.

Another good feature of the indoor receiver is the possibility of volume control. So you can make the most convenient for your level of multiple alarm sounds. Moreover, on the receiver panel, you are always able to see the level of the transmitter battery!

Sensor range

Each model has its own detection range. The Mighty Mule transmission range contains 300-400 feet, which is not little (the shortest transmission range of driveway alarms usually contains only 50 feet!). But if you have a large driveway and 400 feet are not enough, then you can search for the Dakota Alert device.

Home security system

Many customers note the convenience of the driveway alarm in their private space. This device can protect you from any worries about your safety. Due to this wireless driveway alarm, there is no need for you to maniacally check the driveway from your window. Especially if you live at the end of the private road. The alarm receiver will simply give you a signal if any car is passing by your area.

How can I choose the best driveway alarm?

How Can I Choose The Best Driveway Alarm?

In fact, while choosing the driveway alarm system, you need to think about the different features and pitfalls of each model. There are many factors you need to consider in order to choose a good and quality driveway sensor which will inform you about any undesirable guests that come to your territory.

Here are the factors you need to take into consideration while choosing the best driveway alarms:

Different types of driveway alarm systems

There are three different types of driveway alarms: Magnetic probe alarms, Passive infrared (PIR), and Active infrared (AIR). Each type of alarm system has its own character and features.

  • Magnetic probe alarms

This driveway alarm system is really frequent among many homeowners. Inside this device, there is a metal detector, which sensors detect objects from metal only. These alarms detect vehicles but they don’t react to any animals that accidentally came to your area, so these driveway alarms don’t trigger false alarms.

  • Passive infrared alarms

This type of driveway alarm detects object motion with the help of infrared beams. In comparison with magnetic probe alarms, its multiple sensors detect the motion of vehicles, people, and animals. This device is not complicated to install and not so expensive.

  • Active infrared alarms

This device has a more complicated structure in comparison with Magnetic probes and PIR alarms. It consists of a receiver and transmitter. The downside of this driveway alarm is the limited detection range (but still it’s better than nothing!)

Transmission range

Each model and type of driveway alarm has its own sensor range but in most cases, an ordinary transmission range is up to 1,000 feet. It is one of a few factors, which is really important to consider while choosing a special home security device.

Source of power

All the alarm systems need to be powered in order to work correctly. There are three types of driveway sensors that become energy from different sources:

  • Electricity powered alarms
  • Battery-powered alarms
  • Solar-powered alarms with the installed solar panel


We all would agree that it is much more convenient to choose home security devices with an easy installation system. Sometimes it is much easier and faster to call a technician instead of reading instructions and installing the device on your own. But actually many driveway alarms are really easy and convenient to install. Everything depends on the type of driveway alarm, in comparison with magnetic probe alarms, active infrared alarms are easier to install.


A good and quality driveway sensor needs to function even in the horrible weather. So if you live in an area where storms and rains often occur, we recommend you not to forget this factor.

False alarms preclusion

The most serious problem of many driveway alarms is a false alarm. From time to time the sensor detects the motion of passing vehicles and people, so it can be really disturbing. But there is one way to avoid this unpleasant situation- with many driveway alarms, you are able to regulate the sensitivity settings, so the device won’t catch every movement. But everything depends on the model and quality of each driveway alarm device.

Moreover, the latest models of driveway alarms also have smart technology improvements, like video and voice control. All these new options will help you to take your house and the private space under control.
