Hear It From Our Fans

M*****

Absolut game-changer for me. First off, it's the perfect solution to monitor larger areas, but still maintain the ability to see details like faces. But more than that, it allowed new setups. Here are my real-life examples:
Garage: My garage has two doors for the cars, but also two doors at the side to enter the house and the backyard. Now I can let the Bullet monitor my garage and the PTZ with the zoom takes a closer look at the doors at the side. Amazing!

M*****

As a practical example, I have the fix lens overlooking the backyard and the zoom lens protecting the small hut at the outer edge of the yard which has some expensive tools in it. I mounted the camera at the corner of the terrace so that I usually have my privacy because the PTZ looks at the hut, but if I am not home I still can check my terrace and the backyard-door (see picture). That's just amazing and usually would have required installation of three cameras!

C*****

I'm always looking for people or postmen and cars. I find it a very helpful function I already have wifi eufy cams and it is annoying to always scroll through all the videos! So it is definitely more relaxed and helpful to search.
