Have this equipment bought in the summer, as I started to build the house and already planned. Thought that would be really awesome ... unfortunately I was bitterly disappointed when my electrician then in November tried to install. To the device itself: from 20 attempts, it may happen that there 1x worked with sound and a still image, despite a very good Internet connection and device in the WLAN - Otherwise, it did not work !!! (A black screen with no sound). The combination with a mechanical doorbell was not working well. As soon as I put the device into the cradle, rang the mech. Doorbell without interruption ... Apart from the cost of Doorbots and the electrician, I have damaged by you attaching the bracket to the garden entrance and the fence wall ... ie the Doorbot remains preliminary plan because I had holes in the brickwork otherwise. For Seller: ... 2 d. big disappointment .. I (unfortunately only too late) had to find research that this thing had never work properly - that is why it is no longer sold !! - I tried to ask the seller claims to send back the purchased product and with the request to send me a working part or the purchase to refund .... However, I only got a link for an update of the successor model (ring). .. really great!!! All I have now passed my legal expenses insurance.
