Exactly what was promised

Great product that does exactly what Guardline advertises. Great customer service who are on top of their game. Wish all the companies I deal and have dealt with were as professional and helpful. Great dealing with them.

Product and Customer Service at its best

The product is reliable and great. As part of the general maintenance one thing you need to do - make sure the power connections in the internal battery pack is clean when changing batteries. Not an unreasonable thing to do for something sitting outside all year round. Most importantly - when buying this - the incredible support one get. They really know the meaning of customer service. Fast email response time. Great in person phone support. We now have over 20 acres supported by this product - both short range sensors and the long range sensors. Tried other products earlier - but the Product + Company as the full package make it easy to state - this is the best choice one can make.

Love this little sensor

Our driveway is about 400 ft long so we have 2 sensors to let us know if we have visitors. Each unit has a different sound so we know if someone is “driving” down our road or if it’s just a deer passing 1 of the units. Absolutely love it!!

Great product!

The Guardline arrived in a timely fashion. It was really easy to set up and get working. It is very effective at alerting of cars and people approaching the home. I am very pleased with this alert system and would definitely recommend your company and product to family and friends. Great product!

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.

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: In regards to the sensor: If it uses batteries to operate, how long do the batteries last? Is there an indicator light on the sensor to show how much power is left? Thanks
Answers (1)
A: The sensor batteries last about a year. If you live somewhere that gets really cold winters I recommend getting lithium batteries to ensure your sensor works year round. There's an LED on the receiver inside that will flash to alert you to low sensor batteries.
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.
