What Others Say About Us

Jayden P - Drongo - Early Warning System Review

Very reliable, customizable security system. I searched all over and eventually settled on this Voice Alert system. It has worked really well for over a year. All of my sensors are outdoors with no cover from the sun or rain and I haven't had to replace a single one..

Nadine, A - Drongo - Early Warning System Review

I love this. We have one at each entrance to the house too so I sleep better at night knowing that I have a bit of notice if someone is nearby. The dog knows it too now and will run to the front door when the driveway one goes off. The price/value is excellent.

Brian, H - Drongo - Early Warning System Review

What I love about this system is that it can make custom announcements about what zone has motion and can make those announcements in multiple places. As soon as anyone enters/leaves our driveway they unable to approach our house unannounced.
