What is geo fencing ?

[Narlo]

I have read a few articles about it - and wanted to confirm my understanding. 

So, all geofencing really means is that when I leave my house with my phone, I have the ability to arm/disarm the cameras ? 

I am only guessing but it will provide me the ability to say to arm/disarm either when my phone or my partners phone leaves the residence ? 

Can someone put in a laymans language, please ? 

Cheers,

Basicly if you smart phone has GPS, and you set it up to do so, the Arlo will arm itself when you leaving the area of your home.

When you come back and get close to your home it will shut off Arlo

It works very well with one phone, most of the issues I seen are with running two or more phones working with Arlo.
