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 spending as much as a month thoroughly researching and testing a given security product, John writes about his findings in a straightforward, no-nonsense way. He skips the jargon and cuts straight to what actually matters to you as a homeowner or renter. Every recommendation comes with an honest breakdown of the pros and cons, grounded in his personal experience and verifiable facts — so you can make a confident, informed decision about your home's security.
