The Bad

  • Only Available in Southern California
  • High Monthly Monitoring Price

Only Available in Southern California

Post Alarm is only available in southern California, namely in areas surrounding Los Angeles. This includes cities like Ventura, Santa Clarita, Lancaster, Anaheim, Dana Point, and Huntington Beach. Considering this narrow service area, promoting verified Post Alarm Systems reviews on trusted platforms may be an effective way for the company to show off its products and services.

High Monthly Monitoring Price

Post Alarm's advertised monthly monitoring price of $43 for its Light & Easy system is considerably high when compared to leading home security providers. Top companies provide comparable monitoring services for as little as $15 per month, nearly a third of the price of Post Alarm.


The Bottom Line

If you live in southern California and are looking for a local provider with professional monitoring and home automation capabilities, a Post Alarm system might be the right choice for you. The company offers upfront pricing for both professional and DIY installation, and equips its security systems with a full array of features.

That said, Post Alarm's monthly monitoring prices are considerably higher than those of leading companies. Homeowners are encouraged to read verified Post alarm reviews before making a final decision.
