The Top Alarm Companies in Houston, TX – 2025 Rankings
Finding the right alarm system company often means extensive research. For example, the best alarm system companies in Houston, TX, will use their own in-house installers and monitoring teams to maximize your security.
This list uses a qualitative, quantitative, and methodical approach when evaluating Houston’s top alarm companies. Our ratings are based on the following factors:
- Average Customer Reviews (25%): First-hand experiences with business reps are critical for an alarm business since professionalism and reliability tend to correlate with proper installations.
- First-Party Monitoring (25%): Some alarm companies have their monitoring services outsourced to external companies. With in-house monitoring, an alarm company has more impetus to protect your valuables. For this reason, we gave more credit to those companies with in-house monitoring services.
- Alarm Response Times (25%): When a burglary attempt is underway, time is of the essence. For this reason, we gave extra points to companies that emphasized responsiveness over giving alarm events extra time to account for homeowner accidental triggers.
- Commercial or Residential Alarms (15%): Sometimes, different alarm companies work in either residential or commercial environments, and some work in both. We took into account what kinds of services each alarm provider delivered and which worked in multiple sectors.
- System Installation (10%): Not every company installs with their own team. For this reason, we looked at each of the alarm companies in the Houston area and determined if each outsourced their system installations.
