Ekon were recommended on Nest website to use but they charged me £470 for a connecting a doorbell to my already wired connection and didn’t confirm charge until leaving which I was told to pay before Constantine left my property. I had requested a full camera installation but Constantine didn’t bring any stock and I had to pay for his time from arrival.The camera picks up all the street cats but not any visitors at the door. Waste of time.Total con and Nest wouldn’t help.
