Update* I just can't complain enough about this entire system. Cameras won't connect. The rare chance they do they seem to flag a leaf blowing in the wind but miss a person walking directly in front of the camera. It keeps notifying me for a vehicle (the same one that never moves). The mobile app is a digital catastrophe. The only reason I got this system to replace my Lorex was for the 2 way audio which the quality is horrible at best. Taking out back for target practice and bonfire material!!!
