Methodology & Evidence Limits

Data Sources

Our corpus is built from public owner comments harvested from car, regional, and dashcam communities (e.g., r/Dashcam, r/CarsIndia, r/AskUK). These comments are reconciled against a hand-verified spec sheet for each model.

How We Score

• Mention Volume: How often a model or brand is recommended in the corpus.
• Owner Sentiment: An editorially coded score (1-5) for each comment, reflecting the owner's satisfaction. This is not a marketplace star rating.
• Community Breadth: The number of distinct subreddits and threads where a model is discussed.
• Spec Confidence: Specs are graded (High/Medium/Low) based on sourcing. High confidence means verified against official listings or multiple consistent sources.

Model-page shortlist score

The editorial overall score blends owner evidence with a value check and documented capability checks. It is a shortlisting aid, not a performance measurement or marketplace rating. Directory rankings remain ordered by mentions; this separate score does not reorder them.

• Sentiment — 60%: The mean of this model's joined owner-comment sentiment values from 1 through 5. The coded-comment count appears alongside it.
• Recommendations — 25%: Five times the model's comment count divided by the largest comment count among eligible directory models. The most-mentioned model earns five; half as many mentions earns 2.5. These are all model mentions, including reservations, not solely positive endorsements.
• Value — 10%: The model's recorded price scaled against eligible models: the cheapest documented price earns five, the most expensive earns zero, linearly in between. Prices are volatile as-of snapshots, so an undocumented price omits this category rather than scoring it.
• Specs — 5%: Five times the supported share of documented capability checks: 4K front video, Starvis 2 sensor, HDR/WDR, capacitor power, and parking mode. Documented support is not tested performance.

Multiply each available category score by its base weight, sum the results, and divide by the sum of available weights. Undocumented categories are omitted, never scored as absent. Within the specs category, undocumented checks are omitted too, never treated as unsupported. Sparse documentation can therefore make scores less comparable. Scores use unrounded values internally and display one decimal place.

An overall score requires at least one valid coded owner comment and a resolved make and model clearing the evidence gate: at least two joined comments or medium/high spec confidence, with low-confidence records excluded. Brand-only comments never contribute to a model. Capability checks reflect the supplied spec record, not independent testing; confidence and sourcing notes remain in each model's specifications. The weights are editorial choices, not estimates of reliability, safety, or recording performance.

Evidence Limits

• No Lab Tests: We do not test cameras. We measure reported experience.
• Sentiment Bias: Comments are self-selected and often positive. We do not compute failure rates or lifespan claims.
• Sparse Data: Some models have limited comments. These are flagged or excluded from top rankings.
• Price Volatility: Prices are snapshots and change frequently. We always show an "as-of" date.
