With a population of 1.4 million, San Diego is the second-largest city in California. It has a year-round temperate climate, many beaches, a world-famous zoo, and is home to the United States Navy Seal Headquarters.

Factors to Consider When Buying a Home Security System

  • Price & Contracts

    Are you looking to pay for your equipment upfront or finance over a period of time? You’ll also need to decide whether you want to commit to a contract or have the freedom to cancel your provider’s service without penalty.

  • Monitoring

    Choose between 24/7 professional monitoring or self monitoring. Both have its perks – with professional monitoring, a specialist is available around the clock to help, and with self monitoring, you’ll be in charge and can avoid a monthly fee.

  • Installation

    Want a professional to install your security system for you, or would you rather install it on your own? Most providers either require professional installation, DIY installation, or offer a choice of both.
