How to Buy a Security Alarm Company: The Monitoring Map
How to buy a security alarm company before it is listed: who hears first, how to read recurring monitoring revenue, and a 90 day plan to stay recent.

If you want to know how to buy a security alarm company before it is listed, start with the people who monitor, supply and insure alarm dealers: monitoring center account managers, distributor branches, SIA and TMA members, insurance agents and dealer CPAs. Then stay recent, because they mention a ready owner to the buyer they remember.
Here is the scene. An account manager at a wholesale monitoring center is on a call with a dealer who has sent signals through her center for years. He is tired of the 2 a.m. calls. He asks whether she knows anyone who buys accounts.
She knows a few buyers. She texts the one who called her last week.
Why do alarm company owners sell to people they know?
Because an alarm company is its accounts, its technicians and its promise to customers that someone answers when the panel trips. An owner who spent years building that trust wants a buyer someone he trusts will vouch for.
The center sits in the middle. The Monitoring Association says it represents monitoring centers, integrators, installers and manufacturers, and that it was incorporated in 1950 as the Central Station Electrical Protection Association. The people who run those centers watch every dealer’s account count every month. They know first.
Who hears first when an alarm owner is ready?
The people who see the signals, the orders and the policies. This is my map, a framework, not data.
| Who | What they notice first | What they want from a buyer | How you earn a place |
|---|---|---|---|
| Wholesale monitoring center account manager | Account counts flat or falling, owner fatigue | The accounts stay on their center | Ask how they handle a dealer sale |
| Security equipment distributor branch | Smaller orders, fewer new installs | The account keeps buying | Visit, keep buying after close |
| SIA and TMA members | A peer who stopped showing up | A buyer who keeps the techs | Join, attend, help with one thing |
| Commercial insurance agents | An owner asking about coverage or exit | An insurable new owner | Ask how they would write an acquirer |
| Electricians and low voltage contractors | An alarm sub turning down jobs | A sub that still shows up | Ask which alarm shops they use |
| Dealer CPA | Owner age, the “what is it worth” question | A buyer who closes and keeps the client | Send them billable work |
The monitoring center row is the one buyers miss. For the broker side, the IBBA broker directory lets you filter by geography and specialty.
How do you read recurring monitoring revenue?
Treat recurring monthly revenue as the asset and installation as the engine that feeds it. RMR is the monitoring and service fees customers pay each month under contract. It repeats, so it is what a buyer underwrites.
Illustrative math, not market data. Say a dealer has 1,500 accounts at $40 a month. That is $60,000 a month, $720,000 a year. If 10 percent of accounts cancel each year and installs add back only 8 percent, the base shrinks every year you own it. The number that matters is not today’s RMR. It is RMR after attrition.
The decision table I would use in diligence:
| Question | Good sign | Slow down |
|---|---|---|
| Are contracts written and signed? | Signed, with clear terms | Handshake or month to month |
| Can contracts be assigned to a new owner? | Assignment allowed | Silent or prohibited |
| Who monitors the signals? | Named center, clean dealer agreement | Unclear, or terms change on sale |
| How many accounts cancelled last year? | Tracked by month, with reasons | Owner guesses |
| How concentrated is the base? | Many small accounts | A few large accounts are most of RMR |
| Who holds the license? | Stays after close, or a successor qualifies | Leaves at close, no plan |
On monitoring quality, TMA runs the Five Diamond designation for monitoring centers and the ASAP service, which it says covers over 65 million people, for sending alarm signals to emergency communications centers. Ask whether the center the dealer uses participates. The SBA’s guide to buying a business says you will need licenses and permits from the owner or to apply yourself, and to consider an attorney and an accountant.
Which security industry rooms matter?
Two associations and their shows. The Security Industry Association says it has over 1,700 member companies. SIA lists ISC East for November 3 to 5, 2026 in New York City, and ISC West 2027 is listed for April 5 to 9, 2027 at The Venetian Expo in Las Vegas. TMA holds its own annual and midyear meetings. Check the official sites for dates. For working any association room, read trade association acquisition targets.
How to buy a security alarm company: the 90 day plan
Here is how I would run it in one metro.
- Days 1 to 14: pick the lane. Residential, commercial, or both. Monitoring only, or install and service too. An RMR range. Your lender conversation done.
- Days 15 to 30: the centers. Call account managers at two wholesale monitoring centers. Ask what happens to dealer accounts when an owner sells.
- Days 31 to 45: the counters. Meet three distributor branch managers. Ask who is respected and who has no successor.
- Days 46 to 60: the rooms and the money. Join SIA or TMA, or attend a regional event. Meet one insurance agent, two dealer CPAs and an attorney who knows alarm contracts.
- Days 61 to 75: the brokers. Two or three from the directory and from referrals. Send a short buyer profile with your RMR range.
- Days 76 to 90: one owner coffee a week. No pitch. End with “who else should I know?”
- Day 90 onward: a touch every six to eight weeks per person, each with a real reason.
What do you text the people who hear first?
Short, specific, under 40 words. Illustrative examples.
To a monitoring center account manager:
“[Name], thanks for walking me through dealer transfers. If one of your dealers wants out, I would keep the accounts on your center. Happy to just listen first.”
To a dealer owner after a regional meeting:
“[Name], your point about keeping cancellations low with a quarterly test call was the best thing I heard today. Coffee next week? I want to hear how you built it. No agenda.”
To a broker, 60 days later:
“[Name], still buying alarm accounts in the metro, commercial preferred, lender ready. Saw the deal you closed. Congrats. Anything coming that fits?”
For the owners already in your phone, start with owner direct deals from your network. Other trades are on buy a business by industry, and the full system is deal flow for business buyers.
Where does this break?
Between calls. Two monitoring centers, three distributor branches, two association members, an insurance agent, two CPAs, an attorney, two brokers and five owners. Eighteen people. By month four you are in diligence on another dealer and nobody has heard from you. The account manager with the tired dealer texts the buyer who called her last week.
That is the gap FRONT OF MIND closes. At ISC or the regional meeting, say a name and a sentence out loud, snap a business card or badge, or take a selfie together, and it is filed under the event. Each morning it opens on your 10 minutes for today, with a one line reason per person: they posted, their company was in the news, you met and never followed up, or they are going cold. Every draft is a text style message, 40 words max. Nothing sends without your tap, and it learns from your edits. Ask Liala “who do I know at monitoring centers” and get the right people with why.
