Wireless & Cellular Alarm Systems for Homes and Businesses
No landline? No problem. Wireless sensors install fast without tearing up walls, and cellular communication keeps your alarm talking to our central station even when power, phone, or internet goes down.

What a wireless alarm actually has to do
A wireless alarm has to do everything a wired one does. Detect entry. Reach the monitoring station. Keep working when something goes wrong. It just does it without running cable through your walls.
The signal path matters most.
A lot of older systems still send alarms over a phone line, or over a 3G radio that went dead when carriers shut those networks down in 2022. Those systems look fine on the keypad. They just can't reach anyone. We pair supervised wireless sensors with LTE cellular communicators so every signal has a path out.
Who we install wireless and cellular alarms for
- Leased offices and retail spaces where you can't open walls
- Homes with finished drywall, plaster, or hard-to-reach attics
- Businesses dropping landlines to cut monthly phone costs
- Older buildings where running new cable isn't practical
- Detached garages, sheds, and outbuildings far from the main panel

The parts of a wireless alarm system
Wireless doesn't mean fewer features. It means the same protection with a faster, cleaner install.
Wireless door and window sensors
Small battery-powered contacts that report every opening to the panel. No drilling through trim or walls.
Best for: exterior doors, windows, cabinets
Wireless motion detectors
Cover hallways and open rooms. Pet-immune models ignore animals under a set weight.
Best for: interior spaces, homes with pets
LTE cellular communicator
Sends alarm signals over the cellular network, so a cut phone line or dead router can't silence your system.
Best for: any monitored home or business
Dual-path communication
Sends signals over both cellular and internet. If one path fails, the other carries the alarm.
Best for: businesses that can't afford a gap
Supervised sensors
Each sensor checks in with the panel on a schedule. If one goes quiet, you get a trouble alert.
Best for: peace of mind on every device
Long-life batteries
Most sensor batteries last years. The panel warns you well before one runs out.
Best for: low-maintenance systems
What happens when a storm knocks out power and internet
Here's how a wireless system with a cellular communicator handles a rough night at a small business.
Storm knocks out power and internet
The panel switches to its backup battery. Wireless sensors keep running on their own batteries.
Our station gets a power-loss alert
The panel reports the outage over cellular, so we know your site is on battery power.
Someone forces the back door
The wireless door sensor trips. With the internet still down, the alarm goes out over LTE.
Operator dispatches police
Your alarm arrives like any other signal, with the zone and your call list, and police are sent.
Power returns, system reports restore
The panel reports that power is back and recharges its battery. You see the full timeline in the app.
Landline, internet, or cellular: how should your alarm report?
How your alarm talks to the station matters as much as the sensors. Here's how the three options compare.
| Type | Best for | Pros | Trade-offs |
|---|---|---|---|
| Landline (POTS) | Older systems still on a phone line | Familiar, works with legacy panels | Easy to cut, phone lines are being phased out |
| Internet only | Sites with reliable business internet | Fast signals, low cost | Goes down with your router or power |
| Cellular or dual-path | Almost every home and business | Hard to cut, works during outages | Needs decent cell signal at the panel |
Is wireless really as reliable as wired?
It's the question we hear most. Early wireless systems earned a bad reputation. Today's equipment is a different story, and here's what makes it dependable.
- Encrypted signals: sensors talk to the panel securely
- Supervision: every sensor checks in, silent ones trigger alerts
- Jam detection: panels flag attempts to block wireless signals
- Low-battery warnings: you hear about it long before it fails
- Signal testing: we check every sensor and cell strength at install
How installation works
Most wireless installs are done in a day, with no drywall patching left behind.
1
Site walk
We walk your property, map entry points, and test cellular signal where the panel will go.
2
Written proposal
You get a clear list of sensors, communication paths, and monitoring with a fixed price.
3
Install and test
Technicians mount every sensor, test each one, and confirm signals reach our station.
4
Training and support
We set up user codes and the app, and handle battery swaps and service after handoff.
Wireless and cellular alarm FAQs
Is a wireless alarm as reliable as a hardwired one?
Yes, with modern equipment. Today's sensors are encrypted and supervised, so the panel knows right away if one stops reporting. Many of our commercial clients run wireless or hybrid systems.
How long do the sensor batteries last?
Most last several years, depending on the sensor and how often it trips. The panel sends a low-battery warning well before one dies, and we can handle replacements for you.
Do I need a landline for a monitored alarm?
No. A cellular communicator sends signals over the cell network, so you can drop the phone line and still have 24/7 monitoring.
My alarm uses an old 3G communicator. Does it still work?
Probably not. Carriers shut down their 3G networks in 2022, so those radios can no longer send signals. We can swap in an LTE communicator, often without replacing the rest of your system.
What if cell signal is weak at my building?
We test signal strength before installing. If it's weak, we can mount the communicator in a better spot, add an external antenna, or set up dual-path with your internet.
Can I take a wireless system with me if I move?
Often, yes. Wireless sensors can be removed and reinstalled at a new location. We'll check your equipment and help you set it up at the new place.
