Dash Cams, Decoded
Dashcam Lab ranks and explains dash cams by the specs that actually decide picture quality and reliability — the sensor generation (Sony STARVIS vs STARVIS 2), the encoder bitrate (not just the resolution number), whether power comes from a supercapacitor or a lithium battery, and which of the three real parking-mode types a camera actually supports. We don't publish prices or star ratings, every pick names an honest drawback, and for anything involving state or local recording law we say plainly: it varies, check your own jurisdiction — this is not legal advice.
Most "4K dash cam" listings sell the resolution number and stop there. A sensor's pixel count is only the start — an underpowered encoder can turn a genuine 4K sensor into soft, blocky footage the moment it matters, a "STARVIS" badge without the generation number tells you little about actual low-light performance, and "parking mode" is marketing shorthand for three different features that need a hardwire kit to work at all.

How we work
We're a research-based site: we analyze manufacturer specification sheets, published Sony sensor datasheets, and aggregated owner-feedback themes rather than physically testing every camera. We explain tradeoffs plainly, always name a downside, and stick to verifiable spec facts — never invented ASINs, exact prices, or legal-outcome claims. Read our full methodology →
