I've had this for a month and all I can say it's a game changer! Took me about 45 mins to setup and mount on the wall using pre existing wire for a door light which is now unemployed. Picture quality is fantastic, app is super easy and reliable to use, I stallation was a doddle. I have hikvision around the house but the entryway was a blind spot. This is far better than hikvision with the bonus of the floodlights whose intensity is adjustable.
All in all very pleased and 2 other friends have now bought one after seeing mine.
