Should smart homes Record Us Without The Activation Word?

Smart homes are a great asset to our society. They allow us to do trivial task with a press of a button or when we speak a few words. It has been revealed that the smart homes record is without us saying the activation words such as "Ok Google" and "Alexa". In the recalled Google Mini it had a glitch that was named phantom touch which keep it active always and recording. This alone got the Google Mini recalled and raised some other questions such as what have we unconsciously said around our smart homes while we didn't know they were recording. In an murder investigation with 2 friend the police got a search warrant to see if the Amazon Echo one of the friend had to see if the two friends were arguing. They learned that the Amazon Echo has been unconsciously recording them without the users consent. My position on this is that if your going to own a smart home than you have to accept the advantages and the disadvantages that come with it. When you own something that is potentially recording you willing you are effectively waving most of your privacy rights.
