Features And Benefits

Plug-and-play and Easy DIY Installation

Since it is a wireless alarm system, you can install it anywhere you wish. Also, you do not need any professional technician to set up this system. It is a plug-and-play and DIY device, and the whole installation takes only a few minutes. There is a crystal-clear and easy-to-read user manual with step-to-by step instructions. 

I like this sensor because it comes with essential mounting hardware and a kit. It helps in saving my money as I do not have to spend money to buy extra equipment. In general, you will need a drilling machine other than the included tools. 


You can adjust the sensitivity distance of the outdoor motion sensor. For this, you should unscrew the four screws on the sensor box. If your driveway is only for a single vehicle, you can decrease the sensitivity level to 23′. When you receive the sensor, it will have a 39′ level. There are 13′, 23′, 26′, and 39′ adjustment level options. (1)

Depending on my experience, I can say that you should set up the sensor above three or four feet from the ground. This method avoids giving alerts when there are puppies, kittens, or chipmunks. Never keep it on a metal surface. 

Expandable System and Customizable Functions

If you have a large backyard and want to check almost every part, you can add extra sensors to the receiver. Though this model comes with only one sensor, you can add up to 16 sensors. This Guardline model is home to plenty of customizable functions. Also, it allows you to expand the sensors and receivers. 

Wireless Distance

The sensor and receiver can be installed at different places. When you have set up within the range of 500 ft. You can set up the compact receiver in several areas to monitor four different zones. This Guardline sensor can detect movement that’s happening up to 40 ft. 

Movement Detecting Function and False Alarm

The sensor uses the Passive Infrared Technology. It can sense the movement and heat of humans, animals, and vehicles. Also, there is less of a chance of getting false alarms from falling dead leaves. (2)

The Guardline sensors have adjustable sensitivity to make sure that there are no false alarms. If you want, you can keep the gadget in a mode where it can ignore brisk-moving items. There is an option that allows you to keep the sensor in the photosensor option instead of IR detection.

Weatherproof Shield

This sensor itself is weatherproof. All the extra sensors also can withstand weather. It comes with a gasket in the mounting plate. There is a water-wicking tape piece that helps in keeping the water out. You can see a protective weather shield on top of the sensor. This shield keeps the elements inside the sensor safe from rain, snow, sunlight, water, and more. 


The Guardline sensor and receiver use reliable outer materials. This model uses high-quality substances that help in resisting weather elements. It can work for years if installed with proper care and regular maintenance. Sometimes it tends to be less reliable during extreme weather conditions. 


There are more than 30 plus different alert melodies, and you are free to choose any tune from the list. To be precise, the ringer volumes are high decibel with louder volumes than other models. As the chimes are loud, it acts as a fabulous feature for any property. 

If you want to decrease or increase the alert sound, there are many adjustable audio levels. You can set a particular alarm chime for every sensor when you have many sensors on your property.


This Guardline model runs on AA batteries. For the sensor, you have to keep four alkaline batteries, and the description says that they can last for a year. Also, the batteries run for about eight months for my sensor, which is not bad. I like the fact that there are low battery level indicators so I can change the batteries as fast as possible. 

The receiver uses the power from the AC adaptor when you plug it in. Also, the receiver can run on four AAA batteries. You can keep the batteries as a backup when your property has a power shortage. 

Customer Service

They provide great customer support using various methods. You can check out their how-to video tutorials to get more detailed instructions. There is a PDF manual with images and FAQs for easier understanding. 

You can reach out to Guardline using phone, chat, or you can submit a ticket on their official website. The timing for live chat customer support is 7:00 AM – 3:00 PM PST from Monday to Friday. You can’t contact them on the weekend which is a bummer. 

Other Features
