A lot of Las Vegas homes are stucco outside, and if you don’t hit the right backing—or you seal it wrong—cameras and doorbells end up with water paths behind the mount during monsoon bursts. The valley’s loamy alluvial soils with caliche layers can cause tiny shifts that show up as doors not latching perfectly, which matters when you’re installing smart locks and aligning strikes. Then there’s the climate: extreme heat (especially in attics and garage ceilings) shortens the life of cheap power supplies, makes adhesives fail, and can even soften wire jackets over time. Wind and dust are the other sneaky killers—motion sensors get false triggers and door contacts lose alignment when a loose frame or gate starts to rack. The reliable approach is simple: solid fasteners into structure, proper exterior sealing, clean power runs, and Wi-Fi placement that matches the house layout, using readily available parts (mount blocks, transformers, low-voltage wire, anchors) you can get same-day around town.
