The process starts with a consultation to understand your home and security needs. If you already have an alarm system, we can often upgrade and modernize it rather than starting from scratch, saving you hundreds of dollars.
For existing systems, we perform a thorough inspection and install a cellular communicator that connects directly to our monitoring center. No landline required, and your monthly monitoring starts immediately.
New installations include professional placement of door sensors, motion detectors, and your choice of traditional keypads or modern touchscreen control panels. Everything connects wirelessly to avoid drilling holes throughout your home. Once installed, we walk you through the system and mobile app so you're completely comfortable using every feature.
Plan 1 works with your existing alarm system for just $17 monthly. Perfect for Crosby homeowners who want dependable monitoring without replacing equipment that's already installed. Includes 24/7 professional monitoring, cellular backup, and no contracts.
Plan 2 adds smartphone control to your existing system for $22 monthly. Arm and disarm from anywhere, receive real-time alerts, and manage your security remotely. Ideal for busy families who want modern convenience.
Plan 3 provides a complete modern security system with touchscreen control, door sensors, motion detection, glass break sensors, and built-in camera for $27 monthly plus equipment. Given Crosby's property crime rate of 32.77 per 1,000 residents, this comprehensive protection gives families in growing neighborhoods complete peace of mind.
Absolutely. Most existing alarm systems can be modernized and connected to professional monitoring without full replacement. We inspect your current equipment and typically add a cellular communicator that routes signals securely to the monitoring center.
This approach saves you the cost of new sensors, wiring, and keypads while giving you the same professional monitoring as a brand new system. Your existing door and window sensors, motion detectors, and keypads continue working exactly as before.
The upgrade process usually takes about an hour and costs just $139 for setup. You get modern features like cellular backup and professional monitoring while keeping the equipment you already have installed and working.
Your security system stays fully operational thanks to cellular backup communication and battery power. The cellular communicator connects directly to cell towers, so internet outages don't affect your protection.
Built-in backup batteries keep your system running for hours during power outages. Door sensors, motion detectors, and the main panel all have battery backup, so your home stays protected even during extended outages.
The monitoring center receives all signals through the cellular connection, so emergency response continues normally regardless of local service disruptions. This redundancy is especially important in Crosby's growing areas where infrastructure sometimes experiences growing pains.
No contracts required. You can cancel your monitoring service anytime without penalties or fees. This flexibility sets us apart from national companies that typically require 2-3 year commitments.
Month-to-month service means you're not locked into long-term agreements if your needs change. Whether you move, upgrade your system, or simply want to try a different approach, you maintain complete control over your security service.
This no-contract approach reflects our confidence in service quality. Rather than trapping customers with legal agreements, we earn your business every month by providing reliable monitoring and responsive local support.
The monitoring center receives alarm signals instantly through cellular communication and begins response procedures immediately. Trained operators verify the alarm and contact appropriate emergency services within seconds of receiving the signal.
You receive immediate notifications on your smartphone when any alarm triggers, so you know what's happening at your home in real-time. The monitoring center also attempts to contact you directly using your provided phone numbers.
Local emergency services are dispatched according to your preferences and local protocols. Having a local security company means faster coordination with Crosby-area police and fire departments who know the community and can respond more efficiently than distant monitoring centers.
The mobile app lets you arm and disarm your system, receive instant alerts, and check system status from anywhere. The interface is designed for everyday use, not technical experts, so most customers master it within minutes.
Real-time notifications tell you exactly what's happening - whether someone opened the front door, motion was detected, or the system was armed or disarmed. You can customize which alerts you receive and how you want to be notified.
The app works on both iPhone and Android devices and connects through your home's cellular communicator. Even if your home internet is down, you can still control your system and receive alerts because everything routes through cellular networks.
Installation costs vary by system type. Upgrading existing systems costs $139 and includes inspection, cellular communicator installation, and complete system testing. New complete systems include professional installation in the equipment package price.
Professional installation means proper sensor placement, secure mounting, and thorough testing of every component. The technician explains how everything works and trains you on both the control panel and smartphone app.
Installation appointments are scheduled at your convenience and typically take 2-4 hours depending on system complexity. The technician ensures you're completely comfortable with your new system before leaving and provides contact information for any future questions or service needs.
