Fewer false alarms Sensors, delays and codes set for your site
01What we install
What a commercial intrusion system covers
An intrusion system watches the doors, windows and open spaces of your building when nobody should be there, and reports to a monitoring center when something changes. We lay it out from a walk of your building, not from a package list.
Most systems use the same building blocks. What changes from site to site is where each one goes and how it is set up.
The building blocks
- Door contacts on entries, exits, roof hatches, and overhead and dock doors
- Motion detectors for hallways, open floors, stockrooms and offices
- Glass-break sensors for storefronts and window lines
- Panic and hold-up buttons at registers, reception desks and cash rooms
- Unit door alarms for self-storage buildings
- Keypads at the doors your staff use to open and close
- Sirens and strobes inside, and outside where they make sense
- Cellular and network communicators that send signals to the monitoring center
02Your hours and people
Set up around your hours and your people
A commercial alarm only works if the people in the building can run it. We divide the building into zones and areas, so the warehouse can be armed while the front office is still open, or a server room or cash office stays armed all day.
Each person gets their own user code, limited to the areas and hours they need. When someone leaves, you delete one code instead of changing everyone's. Open and close reports show who armed and disarmed the system and when. Schedules can arm the building on time or send an alert when it is still open after hours.
03False alarms
Fewer false alarms, and a response that counts
False alarms cost money and goodwill. Many Metro Atlanta cities and counties, including the City of Atlanta, Cobb County and Johns Creek, require alarms to be registered or permitted, and many charge fines that climb with repeat false alarms.
Georgia law also requires the monitoring center to try to reach you at two different numbers before it asks police to respond to a burglar alarm. Fire, panic and robbery-in-progress alarms, and alarms verified by video or audio, are exempt. Some cities go further. Sandy Springs, for example, does not send police to an intrusion alarm unless it has been verified by video, audio or a person on site.
Most false alarms come from a short list of causes: a motion detector aimed at a heater or a hanging sign, a door that doesn't latch, a code nobody remembers, a call list that's out of date. We design and program to avoid them.
How we cut false alarms
- Sensor types and placement chosen for each space
- Entry and exit delays set to how your staff actually open and close
- Cancel codes and exit warnings turned on, not left at factory defaults
- Staff walk-through at turnover and a current call list on file
04Cellular
Off the phone line, onto cellular
Many older alarm panels still report over a copper phone line. Carriers are retiring those lines, and in March 2026 the FCC eased the rules for doing it. When the line is gone, an alarm that depends on it can no longer reach the monitoring center.
In most cases the fix is a new communicator, not a new system. We add a cellular communicator, or a cellular and network pair for a second path, then test that every signal arrives. If the panel is too old to take one, we show you the options and the cost before any work starts.
05Multi-site
One site or many, planned with your cameras and doors
Retailers, self-storage operators, banks and property managers often run the same alarm at many addresses. We keep panels, codes and reports consistent across sites, so you manage every location's alarms from one place and each new site comes online the same way.
Because we also install access control and video, your intrusion system is planned with them from the start. A forced door can be matched to the camera covering it and the card reads around it. Warehouses get contacts on dock and overhead doors with cameras on the yard. Retail stores get glass-break and hold-up coverage with cameras on the registers.
06Upgrades and takeovers
New systems, upgrades and takeovers
Every job follows the same four steps: a site survey, a design and estimate priced from that design, installation and testing, then inspection and service. If you already have a system, we can usually service it, upgrade it or replace only the parts that need it, including most systems we didn't install. If your insurer or landlord has alarm requirements, bring them to the survey and we'll design to them.

FAQ
Frequently asked questions
Don't see your question? Call us at (678) 619-3548, or request a site survey and ask us in person.
Request a site surveyDo I need to register my business alarm in Metro Atlanta?
In many places, yes. The City of Atlanta, Cobb County and Johns Creek, among others, require registration or a permit, and many charge rising fines for repeat false alarms. Rules and fees vary by city and county, so check with the one your building is in. Ask us at the site survey and we'll point you to the right office.
Will police come when my alarm goes off?
Under Georgia law, the monitoring center must first try to reach you at two different numbers before it requests police for a burglar alarm. Panic and robbery-in-progress alarms, and alarms verified by video or audio, skip that step. Some cities, such as Sandy Springs, require video, audio or in-person verification before police respond. A current call list and cameras at key alarm points help your alarms get a response.
Our alarm still uses a phone line. Do we need a new system?
Usually not. Most panels can take a cellular communicator, which replaces the phone line as the path to the monitoring center. We check what your panel supports, install and test the communicator, and confirm signals are arriving. If the panel can't support one, we price a replacement before any work starts.
Do you provide alarm monitoring?
Yes. Monitoring is available through our central-station partner, which receives your alarm signals, works your call list and requests police or fire response when needed. We set up the panel, the communicator and the call list so signals arrive the way the monitoring center expects. Ask for monitoring pricing with your estimate.
Can you service or take over an alarm you didn't install?
In most cases, yes. We inspect, repair and upgrade most systems on the wall, including ones installed by other companies. Some panels are locked by the original installer or too old to support. If yours is one of them, we'll tell you at the survey and lay out what a replacement would take.
Can each employee have their own alarm code?
Yes, and they should. Individual user codes let you limit each person to certain areas and hours, remove one person without changing everyone's code, and see who armed or disarmed the system in open and close reports. The number of codes depends on the panel, so we size it to your staff.
Can the alarm work with our cameras and access control?
Yes. We design intrusion, access control and video together, so an alarm at a door can be matched to the camera covering it and the card reads around it. For multi-site owners, that means one place to check alarms, footage and door activity across locations.
