A motion light should be chosen from the site and the exact manufacturer’s coverage diagram. Generic mounting heights, angles, and distance ranges do not apply to every sensor or wall.

Start with power and location

Use a hardwired fixture only with a suitable box, wiring method, and installation that meets the fixture instructions and applicable electrical requirements. Use qualified electrical help when the existing circuit or box is uncertain.

Solar models need a panel location that receives the sunlight specified by the maker throughout the relevant seasons. Battery models need a safe, practical service route. Check whether the fixture is listed for the actual wet or damp location and whether the mounting orientation is permitted.

Map the detection zone

Draw the walkway, driveway, doors, street, vegetation, neighboring windows, and camera field. Compare that plan with the exact sensor pattern, aiming limits, minimum and maximum mounting instructions, time delay, sensitivity, daylight control, and manual override.

Longer range is not automatically better. Traffic, branches, animals, HVAC exhaust, and moving shadows can produce unwanted triggers. Mount and aim the sensor according to its manual, then test the entire approach after dark.

Check the light, not only the sensor

Compare delivered light, beam shape, color, glare, and spill into bedrooms or neighboring property. If a camera shares the area, test whether sudden brightness obscures faces or reflective surfaces. A dusk-to-dawn or lower-level mode may fit a site that needs continuous visibility.

Plan maintenance

Keep the lens, sensor window, solar panel, and seals clean. Check whether lamps, batteries, sensor heads, gaskets, and mounting parts are replaceable. A sealed unit may require complete replacement when one component fails.

Sources and limits

The product’s current instructions control installation and coverage. This guide does not prescribe universal distance or mounting-height numbers.
