A perimeter isn't just a fence line. It's cameras, sensors, and lighting working together to stop trouble before it reaches your door[1]. In Green Valley and Anthem, homeowners upgrade their security. They do this after package thefts or strangers walk through yards at night. Older Henderson properties near Water Street often have no perimeter coverage at all, just a front door camera. That leaves side yards and backyards wide open. Desert dust and heat also wear down cheap outdoor sensors fast, so a system built for our climate matters. Waiting until after an incident means you're reacting instead of preventing.
