FAQs for alarm or security system installation projects in Los Angeles, CA

Solar-powered motion sensor fixtures operate independently from your home's electrical system, eliminating the need for complex wiring. Each unit contains its own integrated solar collector and battery storage system. Installation involves simple mounting procedures rather than electrical connections. 

Be aware that heavily shaded locations may compromise performance, and seasonal sunlight variations can affect reliability in some geographic regions.

Most motion detection systems include adjustment controls—small dials or switches—located on the sensor housing. These allow customization of detection distance, sensitivity to movement size, and duration settings for illumination after triggering. For fixtures without built-in adjustment capabilities, aftermarket controllers can sometimes be added. 

Regular testing after adjustments helps optimize performance and minimize unwanted activations from small animals or vegetation movement.

Converting to motion-activated lighting reduces electricity consumption substantially compared to fixtures left continuously illuminated. Traditional outdoor lighting operating throughout nighttime hours (10 to 14 hours) consumes significantly more power than motion-activated alternatives that illuminate only when needed. The actual savings depend on your previous lighting configuration, the efficiency of your new fixtures, and local electricity rates.

The ideal number of security lights depends on your property's specific layout and vulnerability points. Strategic placement matters more than quantity—focus on key areas like entry points, blind corners, and pathways. Analyze your property for potential coverage gaps, considering detection angles and ranges of each fixture. Balancing comprehensive coverage with avoiding unnecessary redundancy helps optimize both security effectiveness and installation budget.
