Your doorbell
Doorbell cameras are popping up everywhere and at first glance, it may seem like a great way to reduce all kinds of crimes in your neighborhood. Unfortunately, the reality doesn’t seem to support that, with independent research showing no decrease in break-ins or overall crime in neighborhoods that have the cameras, according to research published in MIT Technology Review.
Researchers aren’t sure exactly why this is but Paulsen points out that the cameras can still be useful for many things, including helping you see who is at your door before answering it, so they are still worth having if your budget allows.
