I should really switch away but haven’t had the money

Why just not ditch the doorbell camera altogether?

Marketers manage to convince tech-savvy people that their device is almost unusable by manipulating percentages. For example, “50% brighter screen, 30% more energy efficient”. It even worked for me when I didn’t want to buy a previous phone model just because the latest generation had a 50% brighter screen. But then I realized that I was perfectly happy with the screen of my 4 year-old phone.
