When a national alarm company sells you a system, installation goes to a subcontractor, support goes to a call center three states away, and nobody you talk to has ever driven down Westheimer. We work differently: the person who designs your system installs it, the number you call reaches Houston, and we know the local details that matter — which cities require their own alarm permits, what HOAs allow, and how Gulf Coast humidity and storm season affect outdoor equipment.
That's also why we install Ajax: wireless devices with up to 7 years of battery life and cellular backup that keeps monitoring live through internet and power outages — a real concern every hurricane season.
Wireless intrusion detection, sensors, and app control — professionally installed and monitored.
