Guardline 500 Ft. Range Outdoor Motion Sensor

Notifies you whenever motion is detected anywhere on your property! Detects motion from vehicles, people, or large animals.

SUPER EASY TO INSTALL

Our Quick Start Guide has you operational in minutes! 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:

500 ft 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.)

Not useable.

Still waiting on a replacement sensor that I requested. It's been several weeks now has not shown up yet. So the camera system is virtually useless. Thinking on returning it for refund.

Didn't last long.

I've only had it a few months, and it started chiming all the time, so I took it off from where I had it mounted, and it has water in it. Pretty sure that's what the problem is.

Alarm pare

The initial purchase wouldn’t pare. I contacted you help line and was walked thru the steps. I didn’t pare. Was told a new receiver would be sent. Today I put it out and I worked fine. I lost the field of view window cover in the woods we looked for it long and hard. Could I get another some time. Glad to pay for it. Thanks Paul

Awesome product. Stellar customer service.

The driveway alarm worked so good, I purchased a second one. Customer service at Guardline is exceptional. It’s nice to see a business conducting themselves the way Guardline does. I highly recommend their products.

Q: Does this alarm sense when a person crosses the beam? Or only cars? How is the reciever powered? How is the sensor powered?
Answers (1)
A: HI Mark! The sensor detects heat movement so people and cars trigger it! The receiver has a power cord that plugs into the wall for power. It also has a place for four AAA batteries as a backup power source. The sensor uses four AA batteries.
Q: In some of your photos, I notice the sensor has a little roof...does that come with the sensor?
Answers (1)
A: Yes it does!
Q: 12 to 15 degree viewing radius, What exactly does that look like on paper. This needs a diagram as to what this looks like out in the yard ?
Answers (1)
A: The sensor has either a 9 or 12 degree wide viewing angle. At 40' in front of the sensor, this would cover an area 6' wide (9 degrees) or 10 feet wide (12 degrees).
Q: Your specs say that it works down to -4 degrees F. If it goes below that does it need to be brought inside or can it just stay outside and it just won't work? What do you advise to do with the unit for extremely cold weather below -4?
Answers (1)
A: Hi Alissa, the sensor can work below that temperature - just make sure you are using lithium batteries in it. We have plenty of happy customers up in Alaska using our Guardline driveway alarm!
Q: Can a sensor be added to the base unit to not allow the alarm from going off (vehicle leaving)?
Answers (1)
A: You can add up to 16 sensors to one receiver. The sensors can easily capture traffic from cars entering or leaving your driveway.
