Wireless Driveway Alarm FAQs


How does Wireless Driveway Alarm work? 

The Guardline Wireless Driveway Alarm motion detector has a passive infrared lens that activates when it senses both heat and motion. When the Guardline sensor is triggered by a person, car, or large animal, a signal is sent to the receiver in your home that will alert you with a melody. The sensor has a 40ft detection distance and an adjustable field of view of 9-12 degrees wide. 


The Guardline Wireless Driveway Alarm runs of a radio signal, so there’s no wifi or monthly contracts required. Use your Guardline to detect who's on your property, when the mailman arrives, and more. Additionally, the system is waterproof and weather-resistant and designed to work throughout the seasons.


Here’s where you can find some more information.

Can I Pair my Guardline to Multiple Receivers?

Yes, the Guardline Wireless Motion System is completely expandable and customizable. You can pair up to 16 sensors to one receiver, and as many receivers tied to your system as you’d like. Just make sure you’re using the units with the same range. To learn more about how to pair your receiver to multiple sensors, check out this video

How do I know which system works best for me? 

To determine which motion detection system works best for you, you’ll need to decide what your ideal distance is between sensor and receiver. The original Wireless Alarm system supports a maximum range of 500 feet between sensor and receiver, and the long range motion detector supports a maximum range of ¼ mile. Our sensors are rated at a true distance to include objects like trees, walls, or cars. However, if your property has dense forestry, metal walls, or hill inclinations, we recommend you purchase a longer range system.

Are the Original Wireless Driveway Alarm and the Long Range System Compatible With Each Other?

No, the two systems are NOT compatible with each other. Because they each run on different radio frequencies you cannot use them interchangeably. 

How are the Wireless Driveway Alarms powered?

The Guardline Outdoor motion detector is wireless. Each Guardline sensor is powered by four AA batteries that only need to be replaced about once a year. The receiver should remain plugged in, but it does contain a compartment for back up batteries. With a backup battery your receiver can continue to run even when you lose power. 

The receiver also comes with a low-battery light indicator so you can be notified if your sensor or receiver is ever low on power. Here’s a video to learn more

What is a 12 volt relay?

The Guardline receiver comes with a 12-volt relay to wire any powered light, strobe, siren, or external device to be triggered when your receiver is receiving a signal. It’s great for outdoor flood lights, or flashing strobe lights for the hard of hearing, or for use in a loud industrial environment. The 12-volt relay enables your Guardline Outdoor Motion Detector to easily integrate into your existing security system, or customize your new set up to suit your specific needs.


The receiver comes with two dry port contact options, depending on your security needs. You can use these options to power a siren, strobe light, window/door sensors, garage door openers. Any device that runs off of 12volt of power will be compatible with the Guardline system. If you’re not sure which port to use with your device, simply refer to your device’s instructions.

Why Won’t My Guardline Pair? Pairing Issues and More

Pairing issues can be frustrating, but we’re here for you. Typically you will hear a small and short beep when the sensor successfully pairs to the receiver. If you do not hear that beep, first check to see that you have the right units. Long range motion detection units are not compatible with 500ft units and thus will not pair. 

To determine which units you have, check out this troubleshooting blog post. 


If you’ve confirmed that you have the correct units and your Guardline still will not pair, check to make sure both units are properly powered. You can do this by waving your hand in front of the sensor’s eye. If the sensor turns red when triggered by your hand, that means it is working properly. If it does not turn red, please open up the back of the sensor and change the batteries. After changing the batteries, repeat this test once more. 


To learn more about how to pair your sensor to your receiver, refer to the “Powering and Pairing Sensor and Receiver” portion of your Quick Start guide. You can also refer to this video.

False Alarms

If you’re experiencing multiple alarms, it could be due to a few different reasons. To start, examine your sensor’s mounting position. Be sure your sensor is mounted at least three to four feet off the ground to eliminate false alarms from smaller animals, and not facing direct sunlight. 


If you’re experiencing numerous alarms from larger animals such as deer, try adjusting the distance sensitivity down to a lower setting using the method described on page 13 of your manual. Your sensor is automatically set at the pick up distance of 40ft, so adjusting the distance down to 26ft, or even 23ft can help eliminate those extra alarms. For more information, check out this video.

Interference (Sometimes it Works and Sometimes it Doesn’t)

Interference is a pesky problem and it’s all about understanding the limits of your property.  Luckily, we’re here to help. Obstructions on your property such as metal, brick, trees, or inclines in your driveway can cause inconsistent performance. Each layer of interference reduces the distance the signal travels by half. Here’s a video to learn more.  


If you’re experiencing intermittent alarms, you’ll first want to examine your sensor. Is the sensor turning red when it sees motion? If the sensor is turning red when triggered, the sensor may be too far away from the receiver to get a good signal. Adjust the position of the sensor and receiver to create a more reliable connection. 


If the sensor does not turn red when triggered, install new batteries and repeat these steps. If new batteries don't resolve this issue, please contact us for further support.  

Issues When Pairing Multiple Sensors

When working on pairing multiple sensors at the same time, it’s very common for sensors to accidentally pair to a different zone than you’d like. If this is the case, you will need to clear the sensor paired to that zone. To learn how to clear sensors from a zone, refer to your manual. 


Next, proceed with the pairing instructions from your Quick Start guide or your manual to learn how to re-pair your sensor to the receivers. When pairing, it is recommended that you first remove all four of the batteries in the sensor you’re trying to pair to make sure the sensor does not accidentally activate. Once the receiver is in Learn Mode and you have selected a zone and a melody, reinsert the batteries back into the sensor. Once the batteries have been reinserted, waive your hand in front of the sensor to save the pairing. You should hear a single beep to confirm your pairing settings.
