Our Story

Guardline began as a small business in the summer of 2001 in Yelm, WA. Our first office was located in a tiny storage room behind a local children’s theater. At the time, there was only one product launched: a simple, easy-to-use outdoor motion alert system. But over the years, sales grew quickly and our product line expanded to include a range of home security products.


As we gained more experience in the outdoor home security space, we wanted to improve our products and build a better version of them. So in 2011, we started manufacturing our own products. After two years of hard work to develop our own motion alert system, the product launch became a huge success. Our driveway alarms grew into one of the most reputable and sought-after home security systems on the market.


Today, Guardline offers great service and helps hundreds of thousands of customers protect their homes and loved ones. We may be a small team, but we’re dedicated and passionate about what we do. If you’re not thrilled with a purchase from us, we’ll do everything in our power to make things right. And if you need help finding the best product to fit your needs, feel free to give us a call or write to us — we’re always happy to answer any questions.


Thank you for supporting our business. We look forward to helping you find the best solution for all your security needs!

What Our Customers Say


“I wish there were better words for how strongly I endorse this company and this product. Yes, I'd buy again. And no, I'm not affiliated with Guardline. I'm just a guy in Tennessee with a really long driveway that I can't see who's approaching the house until they're right up on me.”

Marcor ✔ Verified


“One might expect a sophisticated device like this to be difficult to use, but the user's guide is both clear and comprehensive. Anyone who can read can set these units up to get the best performance suited to their particular situation.”

Bruce M. ✔ Verified


“We live far in the country and don't keep the gate closed/locked at the road, so it's been so great knowing when people drive onto our place.”

JP ✔ Verified


“Their customer service and follow up could not be ANY better. I received 4-5 emails making sure my initial setup went well and seeing if I had any issues at all.”

Brian D. ✔ Verified


“Guardline is different, you can control the distance of the detection, which is a big advantage. It has far more settings to determine how you want it to work.”
