Best when you want to retrofit an existing landline panel with a cellular communicator; Alula BAT-Connect fits this retrofit use, but your central station must program the device and you must update your monitoring plan.
Best when replacing or ensuring panel compatibility for a landline-to-cellular migration; Alula-compatible panels pair with Honeywell and others, but always verify compatibility and compare provider activation quotes.

Switching from a traditional landline-based security setup to a cellular-first system is a major upgrade. Not only does it eliminate vulnerability to cut phone lines , but it also lets you drop your costly landline phone service entirely.
Depending on your current hardware and preferences, you have two main paths: retrofitting your existing panel with a cellular module or replacing it with a modern wireless/DIY system.
Step 1: Decide Whether to Retrofit or Replace
Step 2: Choose a Cellular Monitoring Provider
If you are upgrading an existing panel, you will need to find a monitoring center that supports cellular routing (such as Alarm.com or Safe Home Central dealers) and sign up for a digital/cellular tier plan. If going completely new, look at market consensus for your style:
Step 3: Check Cellular Coverage and Transition
To help narrow down the best path forward, tell me:
Switching from a landline-based alarm to a cellular-first monitoring system is usually a good upgrade because the alarm communicator no longer depends on a physical phone line that can fail or be cut. Modern systems typically use a built-in cellular module (often 4G/LTE) as the primary path, sometimes with Wi-Fi as a secondary path.
Here are the main options to consider:
| Provider/system | Best for | Cellular approach |
|---|---|---|
| SimpliSafe | Flexible DIY replacement | Cellular connection available with monitoring plans; good if you want to replace an older system without a long contract. Security.org |
| ADT | Professionally installed systems | Modern ADT systems use cellular communication options rather than relying on landlines. Security.org |
| Vivint | High-end professionally installed smart security | Uses cellular connectivity in its smart hub, with Wi-Fi support. Security.org |
| Ring Alarm | DIY + cameras | Cellular backup is available through Ring plans; it can keep the alarm connected if internet fails. Ring |

If you already have a traditional wired alarm:
If you tell me:
You can switch your system by installing a cellular communicator compatible with your current alarm panel or by upgrading to a new wireless security kit.
Switching to cellular-first monitoring stops phone line cuts, speeds up signal times, and lets you drop your costly landline bill.
Steps to Switch Your System
If you'd like, let me know:
I can give you the exact equipment part and recommend a plan for your home.
Absolutely. The key distinction is cellular-first vs. cellular-backup: some modern systems normally use Wi-Fi/internet and switch to cellular when the internet fails, while others can communicate over cellular as their primary path.
If you have an older wired alarm panel, don't assume you have to replace all the sensors. A security installer may be able to keep your existing door/window sensors and add a modern cellular communicator or replace only the control panel. That can substantially reduce the cost of the transition.
I'd specifically ask the prospective provider:
Since you're in the North Jersey area, you could also get a quote from a local installer rather than going exclusively with a national provider. For example, DanCam Security in Kearny and Beacon Protection in Totowa are local/regional security providers; Beacon advertises installation and monitoring across New Jersey.
My default recommendation: if your existing system is old and you don't particularly care about keeping its hardware, I'd start with SimpliSafe vs. ADT. If you tell me what alarm system/panel you currently have (e.g., Honeywell/Ademco, DSC, Interlogix, Napco) and roughly how many doors/windows/smoke detectors you have, I can tell you whether it's likely worth keeping the existing sensors and compare the likely costs of the best cellular-first options.

Yes. If your goal is to replace a traditional landline alarm communicator with cellular-first monitoring, you have two good paths:
If your current system has good door/window, motion, smoke, or other sensors, don't automatically replace everything. First find out the panel manufacturer and model. Alarm.com says many existing DSC, GE Security, Interlogix, Qolsys, and 2GIG systems can be upgraded to cellular communication.
The important distinction is cellular-first vs. cellular backup. Some providers use Wi-Fi/broadband as the normal path and cellular only when the internet fails. If you specifically want to eliminate dependence on the landline and make cellular the primary alarm path, tell the provider that explicitly.
Before switching, I'd verify:
If you tell me the brand/model of your current alarm panel (or upload a photo of it) and whether you want professional monitoring or self-monitoring, I can narrow this down to the best cellular-first options and tell you whether you can probably keep your existing equipment.
Switching from a legacy landline security setup to a cellular-first monitoring system is a great move. Cellular connections are faster, harder to sabotage (no wires to cut), and free you up from maintaining an analog landline.
Here is a clear breakdown of how to make the transition smoothly:
To help you pick the best path forward, tell me:

Yes. If your goal is “alarm monitoring that keeps working when the phone/landline or home internet goes down,” I’d favor a system with cellular as the primary alarm path, rather than merely a landline system with a cellular backup.
You may not need to replace all your sensors. If your existing doors/windows have conventional wired contacts, a new cellular-capable alarm panel can sometimes reuse them. That's worth investigating before buying an entirely new system.
I'd ask any provider these five questions:
Seattle also requires monitored alarm companies to be licensed; the city's current list includes ADT, SimpliSafe, Vivint and numerous local providers.
My starting point: If you want simple + cellular + no long-term commitment, I'd investigate SimpliSafe first. If you want professional installation and a traditional monitored-alarm service, compare ADT and a reputable local installer.
If you tell me what brand/model your current alarm panel is (e.g. Honeywell/Ademco, DSC, GE, Interlogix) and roughly how many sensors you have, I can tell you whether you can likely keep the existing sensors and just replace the communicator/panel, which could save quite a bit.
Yes. The key distinction is cellular-first versus merely cellular backup. If your goal is to eliminate the landline as a dependency, you want the alarm panel to communicate with the monitoring center over cellular as its primary path. Cellular systems can continue reporting alarms when the home's internet is down, and they don't require a traditional phone line.
Keep your existing sensors/panel and add a cellular communicator.
This can be the cheapest route if your existing panel is compatible. Many older systems can be upgraded without replacing every door/window sensor.
Replace the panel with a modern cellular system.
This gives you a new keypad, smartphone app, cellular communications, battery backup, and potentially smart-home/camera integration. Current systems such as SimpliSafe, ADT, and Vivint all offer cellular-connected professional monitoring.
Use a local Houston alarm company to take over the existing system.
For example, Central Security advertises cellular monitoring and cellular communicators, while Allied Home Security & Alarm Monitoring Houston says it can upgrade older systems and use cellular communication while retaining existing contacts where possible.
For a landline-to-cellular conversion, I'd look for:
One important caveat: don't cancel the landline until the new cellular system has been installed and successfully tested with the monitoring center. Legacy alarm equipment can also be incompatible with modern cellular networks, so the exact panel model matters.
If you're in the Houston area, I can also compare 3–5 cellular-first providers available at your location, including monthly monitoring cost, equipment cost, contracts, whether they can reuse your existing alarm sensors, and whether they use cellular as primary rather than backup.
Switching from a landline to a cellular-first home security system is a smart move. Cellular is faster, immune to cut phone lines, and often cheaper if you are paying for an unused landline bundle.
Here is a clear, organized breakdown of what you need to consider and how to make the switch:
If you'd like, let me know:
I can recommend the best upgrade path and compatible cellular modules for your setup.
