How it works

One system, three steps.

1

Something happens

A delivery at the door, a visitor at the gate, an employee badging in at 7 AM.

2

You see it on your phone

A smart alert with live video. Talk through the doorbell or unlock the door from anywhere.

3

It is recorded, and it is yours

Video and entry logs stay on your own equipment, ready when you need them.

You live your life and run your business. Your property looks after itself.
The coverage gap

Most properties are covered in the wrong places.

Cameras that miss the door, Wi-Fi that drops in the back room, keys nobody can track. Move the sliders for a rough starting point for your property.

  • Blind spots at side gates and back doors
  • Wi-Fi dead zones that knock cameras offline
  • Physical keys with no record of who came in

I recently had Quality Technology Systems and Security install a Ring camera system, and I'm really impressed! The team was professional, quick, and left no mess behind. They explained everything clearly, and the camera works great, providing excellent image quality. Highly recommend their services!

Sam is very knowledgeable with the Eufy security camera system. He helped me install the Eufy Floodlight Cam 2 Pro which required installing a junction box. He installed in a timely manner and I'm very happy with the outcome. He's very professional and friendly. I would most likely hire him again for future camera/electrical work.

Freeman S.Home security install · Mar 21, 2023 · Verified on Thumbtack
Super helpful and knowledgeable with setting up our smart doorbell! We also had a separate issue with the interior doorbell chime box (not sure if that's the technical term, ha!) that was plastic and should have been metal... it could have been a fire hazard. Thanks for going the extra mile Sam!

I had 4 rooms wired for Ethernet in my house, terminating in a rack mount patch panel. The wires were run efficiently and dressed professionally. 10/10 I will be calling Sam for any future networking cable runs.
Joseph D.Network wiring install · Jun 19, 2022 · Verified on Thumbtack
Sam was great to work with. We had an ethernet backbone that he brought to life. We were delighted with the outcome. He is also a problem solver and recommended different options for cable placement. We would use him again and highly recommend him to others
Matt S.Network wiring install · Jun 6, 2021 · Verified on Thumbtack
Sam was great. Ended up being able to come a day earlier than expected, which was nice; got the work done quickly and for a good price. I appreciated him being willing to discuss the project a little bit in advance so we could be on the same page with respect to the expected project cost before he drove out - and he ended up staying well in the range we discussed.
Jarek R.Smart home install · Dec 18, 2021 · Verified on Thumbtack
Sam communicated well, was transparent and did what he set out to do in a timely and professional manner. Super easy to work with.
