Terms of Service

Information, not professional advice

Everything on this site is researched general information. It is not professional security advice, not electrical advice, and not legal advice. Camera placement, wiring and recording law vary by property and by jurisdiction, and only you can assess your own situation.

In particular, recording law differs substantially between states and countries, audio recording is governed differently from video, and mains electrical work is licensed in many places. Check your own local rules and use a licensed professional where one is required.

Accuracy

We work hard to be accurate and we label every computed figure as resting on a published standard or an industry convention. Even so, calculated figures are planning numbers rather than guarantees, manufacturer specifications change, and real installations vary with light, weather and how a camera is actually aimed. Verify anything that matters before you rely on it.

Prices and availability

Prices shown here come from product listings and change often. Every price and running total is a guide, not a quote.

Affiliate links

This site earns commissions on qualifying purchases made through its links, as set out in the affiliate disclosure. This costs you nothing extra.

Limitation of liability

This site is provided as is. To the fullest extent permitted by law, we are not liable for any loss or damage arising from the use of the information here, including any purchase decision, installation, or security outcome.

Content

The text, calculators and charts on this site are ours. Product names, images and specifications belong to their respective manufacturers. You are welcome to quote and cite pages here with a link.
