Guardline GL2000 Wireless Driveway Alarm Motion Sensor & Detector
Best motion detector for all size perimeters
This customizable driveway alarm can be used with up to 16 sensors for easier monitoring of properties of all sizes.
1 Guardline GL2000 Review
If you’re looking for the best expandable wireless driveway alarm to monitor a smaller or larger area, you can’t go wrong with the Guardline 4331030700. The system comes with only one motion sensor, but it’s expandable up to 16, so you can easily customize it to your needs.
No matter how many sensors you need, this alarm’s greatest highlight is its easy setup. Thanks to its plug-and-play design, it is ready to use in minutes.
The 500 feet wireless range isn’t the most impressive out there, but it’s realistic. You won’t need another receiver to cover this radius regardless of how many obstacles there are on your terrain. We also like the actual range of the sensor eye that detects movement up to 40 feet.
Designed with outdoor use in mind, this wireless driveway alarm boasts a sturdy PVC construction that resists water and sun. Customizable and easy to use, it is an excellent choice for homes and commercial properties.
eMacros Long Range Solar Wireless Driveway Alarm
Best solar-powered motion detector
Its built-in rechargeable solar battery allows you to set it and forget – no need to remember to change batteries.
2 eMacros Solar Review
Are you looking for a wireless driveway alarm you can just set and forget? Then, check out the eMacros Solar. Running on solar energy, it comes with a built-in, rechargeable battery that requires no replacement. What better way to make sure your driveway or backyard is always protected?
Like the Guardline, it’s a plug-and-play alarm style you can install in minutes. We particularly like that it comes with a comprehensive instructions manual, so you won’t have to struggle to set it up.
The advertised wireless range is half a mile in ideal conditions. In real ones, it will unlikely cover that surface, but it’s still perfect for mid-sized driveways and yards. Another thing we like is that it’s expandable. Even if it doesn’t accept as many sensors as the Guardline, you can still customize it to up to four sensors.
A sensitive sensor eye minimizes false alarms, and the sensitivity is adjustable from 20 to 30 feet. As you’d expect, this motion detector is also weather-resistant, and the alarm also comes with a 5-volt DC adapter if you don’t mind the wire and don’t want to rely on the solar battery alone.

More expensive, longer signal range
Sturdy, weather-resistant construction and heavy-duty signal range define this dependable alarm.
3 Driveway Informer DI2000S-GA Review
Similar to our best-value pick, the Driveway Informer DI2000S-GA is an expandable wireless driveway alarm developed for perimeters of all sizes.
A longer signal range up to 1,000 feet, though, makes it more suitable for mid-size and large perimeters.
Easy to operate, this driveway alarm is easy to transform into a reliable multi-purpose alarm thanks to the versatile receiver which features two terminal screws for adding accessories.
Furthermore, the receiver also has a resettable LCD display counter and a convenient volume control knob.
Developed to detect humans, animals, and vehicles, the alarm can be used for various applications, such as keeping your property safe, monitoring your pets, and more.
Discreet, reliable, and with a long signal range, the Driveway Informer DI2000S-GA is a great alternative for a large property.
1byone Motion Sensor 1000ft Driveway Alarm
A cheap alternative
Three alert options and 36 sounds give you plenty of ways to scare off intruders or be alerted of visitors.
4 1byone 6-O00QH-0499 Review
If you can’t afford expensive motion detectors but still want to be alerted of visitors or intruders, the 1BYone 6-O00QH-0499 could be the best wireless driveway alarm for you. Simpler than our other options, it comes with two sensors that give you the possibility to monitor various areas of your property.
The system has a wireless range of 1,000 feet, and if two sensors are insufficient, you should know that you can expand the system with up to 5 sensors per receiver.
Despite its lower price tag, this motion detector is sensitive enough to detect not only humans and vehicles but also larger animals. Furthermore, we like the alert and sound options, as well as the three volume settings.
Sure, this wireless alarm may not be as sensitive or as durable as the most expensive ones, but it’s an excellent budget choice.
1. Why invest in a driveway alarm?
Driveway alarms are designed to monitor the perimeter, gateway, or entrance of your home or business, but these versatile systems can serve many other purposes.
For instance, a driveway alarm can monitor a:
- Pool or basement entrance;
- Garage entrance;
- Your pets or kids;
- Animals getting into your garden, especially in a rural area.
Depending on the area you want to monitor, you can buy single or multiple sensor systems, and some even accept multiple receivers you can place in various areas of your home or business.
2. Wired vs. wireless driveway alarms
Driveway alarms come in wired and wireless variants.
- Wired driveway alarms: Are the most affordable models. These alarms are very reliable and simple to operate. They also have no batteries to recharge or replace, but are impractical for large properties or in areas where running a wire is impossible. The wire can be damaged by animals or people, therefore you will have to bury it.
- Wireless driveway alarms: Are perhaps the most popular. Installing these systems is a breeze, but their efficiency can be affected by interferences between the sensor and receiver, such as trees or thick walls. Depending on the characteristics of the area to monitor, the wireless alarms may or may not be effective.
3. Wireless driveway alarms power source
Wireless driveway alarms consist of at least a sensor and a receiver, and each component is powered by an independent source.
The sensors can be powered by:
- Traditional batteries: The most popular power source. Most sensors use one or two AA batteries which typically provide energy for up to a year.
- Rechargeable lithium-ion batteries: Typically powered by 9-volt batteries with a runtime of about a month. These batteries recharge either via a traditional charger or via integrated solar panels similar to those employed by portable solar generators.
The receiver is typically a corded device which plugs into a traditional wall outlet. Some of the best wireless driveway alarms come with hybrid receivers powered by either batteries or alternating current.
4. Types of sensors
There are two common types of sensors (or detectors) employed in the construction of the wireless driveway alarms.
1. Passive infrared (PIR) sensors
Are typically powered by standard AA batteries, although some models are equipped with rechargeable lithium-ion batteries. These sensors are very easy to install, and they monitor the area within their designated range constantly, detecting the infrared radiation emitted by an individual, animal, or vehicle.
Their main advantage is that they don’t have to be aligned with other objects to work, and they are easy to hide, for example behind a gate post or fence panel.
PIR driveway alarms come with a variable number of sensors, from one to four or over.
Where to install PIR sensors?
PIR detectors are typically installed at a height from 3 to 6 feet on:
- A wooden post or fence;
- Behind a gate post;
- Hidden inside a birdhouse;
PIR sensors are particularly useful in rural areas if you want to detect wildlife or pets getting into your garden.
2. Active perimeter beam sensors
Active perimeter beam sensors work in pairs; these systems require to install two sensors one in front of the other. The two detectors create an invisible beam and transmit a wireless signal to the receiver when the beam is interrupted.
These sensors can work at further distances than the PIR systems and are less likely to give false alarms, as they are not detecting infrared radiations.
Where to install active perimeter beam sensors?
Ideal to monitor wider areas, but always working in pairs, the active perimeter beam sensors are best installed at a height between 3 and 6 feet on:
- Opposite gateway posts;
- Entrance brick pillars;
- Two wooden posts.
Active perimeter beam sensors are ideal to use in urban areas to monitor the access to your property.
5. Transmission range
The transmission range determines the maximum distance between the sensors and the receiver. Manufacturers typically disclose the transmission range in the product’s name or in its manual, but you must know the real range may not coincide with the indicated one.
This happens because manufacturers measure the transmission range under ideal and uninterrupted conditions. In real life, any physical obstacle, including walls, will reduce the wireless transmission.
How to calculate the right transmission range?
To make sure you’re buying the best driveway alarm for you, estimate the maximum distance between the sensor and the receiver, and double it to account for the signal loss; if there are many obstacles between the devices, it is recommended to quadruple the range.
For example, if your house is located at 300 feet from the gateway and you want to install the sensors on the gateways posts, it is ideal to buy a system with a transmission range of 600 feet to account for any signal loss due to trees, plants, and walls.
Which transmission range do you need?
Assessing the transmission range using the formula above is easy, but the examples below can help you figure out without hassle which transmission range is best for you.
Under 1,000-foot driveway alarms are best for:
- Monitoring your front door
- Monitoring the mail box
- Monitoring the garage or shed
1,000 – 2,500-foot driveway alarms are best for:
- Monitoring a long driveway
- Monitoring the end of the road
- Monitoring the fence line around the property
- Monitoring multiple entrances
- Smaller properties to offset natural obstacles
Over 2,500-feet driveway alarms are best for:
- Monitoring large properties or to offset natural obstacles
- Monitoring construction sites
6. Other important features
A few other important features can make the difference between an average and the best driveway alarm.
- A 12V relay output is useful if you want to connect the alarm to an existing security system. This output also allows you to link the sensors to lights that can either alert you or scare intruders.
- If you want flexibility in monitoring a wider area, invest in an expandable driveway alarm system. Most alarms accept multiple sensors and some even accept multiple receivers.
- A loud and volume-adjustable alert sound is important. When using multiple sensors, some receivers give you the possibility to customize the sound for each of them, so you know which one transmitted the signal.
- Invest in a driveway alarm that is easy to install. Also, make sure the user manual is comprehensive and easy to follow.
- Make sure the sensors come in a weatherproof case that can withstand adverse weather and low temperatures.
- A swivel mount is important if you want to adjust the focus and detection angle.
