There is a huge 5 minute lag between someone coming within range of camera and the notification you receive about it. I'm running gig speed internet with a C7800 Nighthawk router. Hub and door cam is within 15 ft of each other. The app is great as far as navigating and options for tweaking your cams but the delay is horrible.. running just 2 of the Arlo 4k Ultra cams and base. 2 way audio doesn't work either noatter how much troubleshooting you do. There's better camera systems out there too.
