John Carlsen

John Carlsen is a Utah-based home security expert specializing in security cameras, smart home devices, and DIY security systems. He spent the last 10+ years testing, researching, and reviewing smart security products for big publications such as CNET, TWICE, Android Police, Home Theater Review, SafeWise, ASecureLife, and Top Ten Reviews.

Using his Bachelor’s degree in Communications, with an emphasis in Journalism, from Utah Valley University, John leverages in-depth research into security industry sales tactics, pricing practices, contract terms, and customer satisfaction for his reviews. Where possible, he supports his research with hands-on tests — often evaluating multiple products at once in his home office — using scientific principles that are easy to reproduce.

After thoroughly researching and oftentimes spending up to a month with a security product, John writes about his experience and research in a direct manner. He avoids wordplay and meaningless specifications to get straight to the points that his readers care about most. Every recommendation is paired with the positives and negatives of the product based on John’s personal experience and verifiable facts. That way, you can make the best decision for your home’s security.
