Best Buyer Scope.
Home Security Gear, Reviewed by Coverage — every product bought at retail price and tested in real life. No sponsored verdicts, no recycled spec sheets.
How It All Started
In 2022 our founder Marcus bought a four-camera kit that covered the same corner of the yard from two angles and missed the side gate entirely. The app called it “full coverage.”
Best Buyer Scope reviews home security gear by zone — outside, doors, inside, and alerts — buying every product at retail price, installing it in a real house, and mapping what it actually covers.
Today we’re a small team in Austin with more than 30 security products tested and one rule: a device that adds no new coverage doesn’t get a good score, no matter how many features it lists.
What We Stand For
Four promises we’ve kept since day one.
Bought, Not Borrowed
Every product is purchased at retail price with our own money. Review units from brands are declined or clearly marked.
Tested in Real Life
Installed, used, worn, and broken. If it can’t survive real daily use, it doesn’t score well.
One Honest Verdict
Each product gets one score out of 10 with the trade-offs stated plainly. We never take payment for a good score. Read our Disclosure.
Re-Tested Yearly
Products change fast. We re-review every product every year and update scores when better options appear.
