Sources and specification checks
Model specifications are based on supplied product registration sheets and available product materials. We separate WiFi and 4G versions, even when they share a similar model name.
When a specification is missing or uncertain, we avoid presenting it as a confirmed fact. Product details can vary by production batch, market and supported application.
How recommendations are made
The camera selector prioritises site compatibility: placement, connection, power and coverage. It does not rank models by payment from an advertiser or by the highest specification number.
A recommendation is a shortlist for comparison, not a guarantee that a product is suitable for every installation.
Calculators and estimates
Storage and mobile-data results are estimates. Actual use varies with bitrate, resolution, encoding, activity, live-view time, alert frequency and device settings.
- Inputs are shown to the user
- Results are rounded for planning
- Limitations are stated beside the result
- Important choices should be confirmed against the model specification
Corrections and updates
We revise content when a confirmed specification or compatibility rule changes. Clear corrections are prioritised over preserving older wording. Readers should rely on the latest date displayed on policy and guide pages.
Advertising independence
Advertising may help fund the site, but advertisers do not receive control over our compatibility rules, calculations or editorial conclusions. Sponsored or affiliate relationships will be labelled when they exist.
