Every guide. Primary sources.
Written from datasheets, reference designs, FCC filings, and field notes from TruSentry installs. Not rewrites of press releases. Not summaries of other people’s reviews. When we say a camera sensor runs 12-bit ADC, we pulled that from the sensor TRM. When we say a mounting bracket fails in high wind, that’s from a real install. No manufacturer pays to influence our analysis.
