Your driveway and garage are often the two top places where you store your vehicle. Yet, it usually does more than just store it—many garages also provide your home entrance via a side door. Inside your home is where you keep your valuables. Home is where your family makes memories, and where you and your significant other can grow old together. To ensure everyone's safety, you need a home system that works to protect them. To ward off potential intruders, it requires the installation of a driveway alarm.

Before anyone can get near the door of your house, you can receive an alert of their presence. A driveway security system should be durable, accurate, and require minimal maintenance. The safety of your home does not begin or end at the door. Thus, it is an absolute must that you extend your home's security to include your driveway.

Benefits of Driveway Alarms

  • Safety. A driveway alarm alerts you to unwelcome people or animals on your property. The chime in your home can alert you to potential trouble so you can prevent an unsafe situation before anything happens.
  • Package deliveries. With a driveway alarm, you’ll know exactly when items are delivered. This prevents your packages from sitting on your front step for hours and stops giving thieves the opportunity for theft.  
  • Preparedness. With a driveway alarm, you’ll never get caught unexpectedly by unplanned visitors. A chime in your home will alert you to surprise visits so that you’re always ready for guests. 

Types of Driveway Alarms

Passive Infrared (PIR)

This is the most common type of driveway alarm sensor. It uses a passive device to trigger a sensor when objects get near it. This type of sensor can detect heat. This includes heat generated from people, car engines, or larger animals. 

When the sensor detects changes in temperature, it sends a signal to the receiver in your home. Then the receiver emits an audible sound to alert you. 

Active Infrared (AIR)

This type of sensor uses a beam of infrared light to detect movement. Unlike a PIR unit, there are two pieces to an AIR unit. Place one unit on either side of the driveway so that the light emits out of one, reflects off the other, and returns to the original unit. 

A signal is triggered to the receiver in your home when something moves through the beam of light to interrupt the signal. This could be a vehicle driving on your driveway or a person or animal walking on your driveway. 

Magnetic Probe

This type of driveway alarm uses metal detection to trigger an alarm. There’s a sensor that’s typically encased in a PVC pipe. You place the pipe partially underground next to the driveway. Then when a vehicle rides up your driveway, the metal sensor in the wand triggers the alarm. 

This type of alarm stands out because it eliminates the risk of false alarms. Since it only detects metal masses, people and animals won’t trigger the alarm. 

Top Brands

Driveway Alarm Pricing

  • Under $50: Alarms in this price range tend to use simple technology, such as magnetic alarms. They also have shorter signal ranges.
  • $50 to $100: Alarms in this range use more advanced technology and will have more sensitive sensors and longer signal ranges. The unit construction is also more durable.
  • $100 and up: Units in this range are either top of the line or have multiple sensor units. These are typically a complete system. 

Key Features

Power Source

You’ll find driveway alarms that use solar power and others that operate with battery power. There are a small number of alarms that will hardwire into your electrical system. Choose a power source that will be reliable long-term. If you live in a place that isn’t very sunny, then a solar-powered alarm may not be the best option. But keep in mind that battery-powered alarms will require you to regularly change the batteries when they die. 

Sensor Type

There are three types of sensor alarms available. The type you choose depends on the type of driveway you have and what you’re trying to be alerted about. If you’re worried about false alarms and are only concerned about cars, then a magnetic sensor may be the best choice. If you want to know about any movement in the general area, then the PIR sensor may be best. 

Durability 

Your driveway sensor will be outside year-round. This means it needs to be durable enough to withstand various weather elements. Look for a driveway alarm that’s waterproof and has UV protection. It should also be securely made so that wind won’t pull it apart. If the alarm goes in the ground, then make sure it’s durable enough to survive the ground freezing. 

Other Considerations

  • False Alarm Prevention. Nothing is more frustrating than having the alarm trigger multiple times a day or in a row, only to discover that nothing is in your driveway. Consider what features the alarm has to prevent the triggering of false alarms. This could be a sensor radius adjustment or sensor angle adjustment.
  • Receiver Range. It’s important to know how far away you can place the receiver from the sensor. If it’s too far away, you’ll never get alerted. This signal is also affected by things blocking the signal, such as vehicles, trees, and buildings. Look for an alarm with a strong signal that can reach beyond these things. 
  • Reliability. The only thing worse than false alarms is missed triggers. The whole point of having a driveway alarm is to alert you when people are in your driveway, so you need the alarm you buy to be reliable and not fail to trigger when it should.

Tips

  • Buy an alarm system that lets you adjust the sensitivity of the alarm. This will give you better control over where and how the sensor works. 
  • If you have a long driveway, look for an expandable system. Then you can have multiple alarms to indicate that someone is traveling the entire length of the driveway. 
  • Consider the amount of vegetation you have around the driveway alarm. The wind could trigger false alarms by moving the tree branches. 

FAQs

Q. How does a driveway alarm work?

A: Driveway alarms work in three ways. Some systems use magnetism to sense a large mass of metal going by them. This will alert you to vehicles on your driveway. Other sensors use an infrared light beam. When something crosses the beam, it temporarily blocks it, and that triggers the alarm. A third way they work is by sensing heat. This will be the heat of a vehicle engine, a person, or a larger animal. 

Q. How can I hide my driveway alarm?

A: The first step is to buy an alarm unit that’s naturally colored. That way, it blends into the surrounding nature. You could then install your unit on a wood post or nearby tree. If you have a fence around your property, you could install your alarm on the fence post. 

Q. How do you install a wireless driveway alarm?

A: Follow the directions that are provided by the manufacturer. Typically, a magnetic alarm will require you to bury a portion of it in the ground. An AIR system will need to be installed just above the ground level because the lightneeds to cross your driveway so that someone traveling on it would block the light in their path. A PIR sensor needs to be installed high up to have a full sensor radius to detect heat in several directions. 

Q. Can pets trigger motion sensors?

A: Yes, depending on the type of sensor you install. An animal will not trigger a magnetic sensor because animals aren’t made of metal. They may trigger an AIR sensor if they cross the infrared light line. But if they jump over or go around the light line, they won’t trigger the alarm. A PIR will trigger based on the animal’s movement or body heat.
