GUARDLINE 1/4 MILE WIRELESS OUTDOOR MOTION ALERT notifies you whenever motion is detected anywhere on your property! Detects motion from vehicles, people, or large animals. 

We're offering our most popular bundles at a discounted price with the opportunity to add even more extra sensors or receivers to your system (up to 16 sensors and unlimited receivers)! 

SUPER EASY TO INSTALL: Quick Start Guide has you operational in minutes! Set includes one sensor & one receiver. Expandable up to 16 sensors and unlimited receivers for complete coverage of your perimeter. Over 30 chimes to choose from. Match different chimes with different sensors around your property to differentiate where motion is being detected. LOUD & adjustable volume. 

EXTREMELY DEPENDABLE: Two years of testing went into developing a reliable motion detector that will dependably alert you to motion around your property. Tested through thick forestry, hail storms, gusty winds, heavy rains, scorching heat, and snow. Minimal false alarms. 

REALISTIC & RELIABLE RANGE: 1/4 mile long range has been tested in real world settings with trees, buildings, walls, and vehicles in order to make true and realistic wireless range claims (extra heavy interference such as thick walls, metal siding, tall hills, and many trees will diminish the wireless range.)

AWESOME SUPPORT: Guardline Security is a Seattle-based small business that has been selling outdoor motion alerts since 1999. We’re passionate guys who put many years into developing quality motion alerts we can really stand behind. We offer reliable expertise and after-sale support because we genuinely care about your positive experience. We are constantly improving our product/service and we welcome customer feedback!

Great Product

This is an excellent replacement for our "Reporter" alert system. We actually have it further away from the receiver than our previous sensor. We can still see it from our residence so we can determine if it is a vehicle or a critter (unless it is dark outside - but that's when our spotlight flashlight comes in handy). I especially like the different sounds with multiple sensors.

Works like I hoped it would

Simple setup! Works great. Installed one at cattle guard and another at barn lot, no more surprises!!

Works great for us!

We have one sensor on the long drive in and another on the barn so we know if someone's sneaking up or trying to make off with our property. Great product.

Protecting mother in law's house

I bought the 4 sensor pack to protect my mother in laws house which is two houses over. I have 2 on her property and 2 on mine. If zone 3 or 4 go off, I know someones on my property and I handle it.

Q: Looking at the 1/4 mile unit for my in-laws. They live in W NC. The driveway is up a gentle 15-20 degree slope with many trees on both sides of the road. How will the unit work with multiple sensors? Biggest concern would be the one at the bottom of the driveway as there are two 90 degree turns prior to getting to the main county road.
Answers (1)
A: Hi Mark, if your distance between sensor and receiver is under 1/4 mile, then this unit would be great for this because it has a stronger signal that allows it to fight through interference such as the hill and trees. Just remember, as you introduce more interference, your effective range will diminish little by little. Take care!
Q: Some of the pictures, of the sensor, have a shield on the top and some don't. Does the sensor unit come with this protective shield?
Answers (1)
A: The sensor comes with the sun shield bot both the 500 ft, and the 1/4 mile version.
Q: Can the sensor be mounted on a metal pole/pipe without any interference?
Answers (1)
A: We recommend not mounting on metal surfaces because they cause a great deal of interference with the sensor's signal. You can try it in the location. but if it does not work, the metal interference is most likely why.
Q: Will the wireless waves from the camera to the monitor be blocked by trees and hills?
Answers (1)
A: They will not be entirely blocked, but solid objects do degrade the signal strength. Basically, the system has a maximum range, and solid objects will make that range smaller. Certain items such as metal and stucco cause much more trouble that wood or drywall.
Q: Can external devices be activated when motion is detected? For example, could it turn on an external floodlight or alarm that has its own power source? Thanks
Answers (1)
A: The GL5000's receiver has a set of wet contacts (12 volt) and a set of dry contacts. The wet contact only activates for a brief moment though, while the dry contact activates a device with its own power source.
