Every property in Atlanta is different, so pricing depends on your needs—whether that’s a quick residential setup or an integrated system with access control for a business. Factors such as the number of cameras, property layout, and whether you choose 24/7 professional monitoring play a major role.
Instead of pushing prepackaged bundles of equipment you might never use, we provide transparent, upfront estimates tailored to your space and budget. Give us a call or request a free quote, and we’ll walk you through exact pricing with no high-pressure sales pitch.
If you want total peace of mind, absolutely. While self-monitoring sends alerts to your phone, you might miss a crucial notification if you’re in a meeting, asleep, or driving.
With 24/7 professional monitoring, an active dispatch team is always on standby. The moment a smoke detector, glass-break sensor, or burglar alarm triggers, verified operators act instantly to contact you and dispatch local emergency responders—ensuring your home or business is protected even when you’re completely off the grid.
Yes! All of our modern residential and commercial security systems integrate seamlessly with intuitive mobile apps. From your phone, you can arm or disarm your system, view live HD camera feeds, lock doors remotely, adjust thermostats, and receive instant push notifications when a sensor is triggered or someone arrives at your door.
For outdoor protection in Georgia’s climate, you need weather-resistant cameras with high-definition resolution and strong low-light capabilities. We typically recommend IP cameras featuring:
IP66 or higher weatherproofing to withstand heavy rain, heat, and humidity.
Infrared or full-color night vision to capture crisp detail in pitch-black conditions.
Smart motion detection to distinguish between human activity and passing wildlife or swaying trees.
During our site assessment, we’ll help you select the exact hardware needed to cover your property’s blind spots cleanly.
In most cases, yes! You don’t always need to tear everything out and start from scratch. Our technicians can evaluate your existing equipment, wiring, and panel to determine what can be repurposed. Often, we can take over and upgrade older or non-functioning systems by adding modern smart panels, higher-resolution cameras, or mobile app integration, all while keeping your overall hardware costs down.
Yes, we professionally install both.
Wired systems (like PoE IP cameras): Ideal for new construction, commercial properties, or larger setups where maximum reliability, continuous recording, and zero signal interference are required.
Wireless systems: Great for flexible placements, retrofit installations, or areas where running physical cables is difficult.
We’ll evaluate your building layout and recommend the best fit—or even a hybrid solution—based on your property’s structure.
Yes, commercial security is one of our primary specialties. We work with business owners, facility managers, and retail spaces across Metro Atlanta to install integrated security infrastructure, including:
Commercial-grade CCTV and surveillance arrays
Burglar and intrusion alarms
Keyless access control and employee tracking
Commercial fire alarm and life safety detection

Yes, that’s one of the primary advantages of replacing traditional keys with an electronic access control system. Using keycards, fobs, PIN codes, or mobile credentials, you can:
Maintain real-time digital logs of who enters specific doors and at what time.
Grant or revoke access permissions instantly for individual employees.
Restrict sensitive areas (like server rooms or inventory spaces) to authorized personnel only.
Yes. Even if we didn’t perform the original installation, our team provides repair, troubleshooting, and maintenance for a wide range of security systems and camera configurations. Whether you’re dealing with camera feed outages, beeping alerts on control panels, faulty door sensors, or wiring issues, our technicians can diagnose and fix the problem promptly.
For most single-family homes or standard retail setups, installation is completed in a single day. Larger commercial projects or custom multi-location deployments depend on the building layout and cabling requirements.
During your initial consultation, we provide a clear project schedule and schedule installation around your convenience or business hours to minimize disruptions.
