About Sensor & Latch

Sensor & Latch covers home security through one organizing question: what does this cost to keep running once the box is open? Its hero states the angle in a line — "Subscription-Free Home Security, Specced Honestly" — over the promise of "locks, cameras, doorbells and sensors that work without a monthly fee," with the specs, "the real cost to keep each one running, and who should skip every pick" published for each. The site is organized around that: a no-subscription track alongside smart locks, sensors, cameras, and doorbells, plus rankings, head-to-head comparisons where the storage model or the total cost decides it (Ring versus eufy, eufy versus Wyze, eufy versus Reolink), and a guides library that answers the questions buyers actually get stuck on — the five measurements that decide whether a smart lock fits a door, what each protocol costs you offline, Matter and Thread explained for security, local storage versus cloud, and whether a video doorbell is worth it at all.

Its defining decision is printed where most of the category bluffs: "Products we claim to have tested: 0," and, in its own words, "we have not tested any, and we say so." The about page is blunter still — "We do not test hardware. We do not own it, install it, mount it, drill for it, or leave it on a door for six months" — calling what it offers instead "expertise by method rather than by possession." That method is published in full: compile every product's specifications from the manufacturer's listing and manual; cross-check protocol and radio support against the Matter and Thread certification listings, with an FCC ID lookup where a spec sheet is ambiguous; score 0–10 on category-specific metrics — security, door fit, offline and local control, battery and power, ecosystem, storage, image, install, and no-subscription value — with the overall figure stated as the arithmetic mean of those; and compute a five-year cost of ownership as live purchase price plus consumables plus subscription across five years, with the inputs stated down to the assumed cost of a single AA cell. Where a maker withholds a figure the cell reads "Not published" — the site notes it "never reads zero, and it never reads a dash that could be mistaken for zero." It refuses the category's fear-based marketing, and the counters on its homepage make the standard checkable: 54 products carrying live prices, and 105 of 105 picks carrying a "skip this if." Prices render live from Amazon with the date they were checked, and once the data goes stale the number disappears "rather than lying to you."

That refusal to claim a test it never ran is exactly how Type 5 Marketing operates. The brand is funded by "affiliate commissions, and nothing else" — it sells no placements, runs no sponsored posts, accepts no free units, and states that no brand pays to be included, ranked higher, or left out, and that no brand sees a page before it is published. Written and bylined by Stephen V., who operates it solo, it leads with the published spec, does the cost-of-ownership arithmetic in public in enough detail that a reader could rebuild any ranking from the same documents, and admits the work it hasn't done — the standard we hold across every property in the portfolio.
