Important notes

Check sensor blind spots, nuisance triggering, camera interaction, glare to neighbours and roads, shielding, product environment, and electrical cable routes.
Outdoor electrical work, obtrusive-light assessment, and Australian requirements need qualified review; this planner makes no automatic compliance claim.

\(\displaystyle A = W \times D\)
\(\displaystyle n = \max(N_{\mathrm{zones}},\lceil A/A_{\mathrm{beam}}\rceil)\)
Security lighting can support visibility but does not guarantee safety, crime prevention, or compliance.

Estimate residential security-lighting coverage, sensor reach, and glare or spill review prompts without promising crime prevention.

Residential Security Lighting Planner is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
