Most articles about alarm lead generation rank channels by cost per lead. For this trade that is the wrong first question, and the data explains why.
In SafeHome.org's 2026 market report, a survey of 2,435 US adults, only 7% of home security users had switched providers in the previous three years. Meanwhile 61% of US households already own a security camera, and just 5% of non-users planned to add professional monitoring in the next twelve months. The category is saturated, sticky and largely self-served.
That changes what a lead source is for. In HVAC, demand generates itself: a furnace fails and somebody has to call that day. Nobody has an alarm emergency. So the sources that work in security reach a buyer at a moment when something has already forced a decision, and the ones that fail ask a comfortable stranger to start paying monthly.
Here are nine sources ranked on that basis, with what operators in this trade report paying and getting.
The ranking
| # | Source | Trigger it intercepts | Effort | What operators report |
|---|---|---|---|---|
| 1 | Integrator, MSP and electrical subcontracting | Budget already approved | Medium | Consistent volume, thinner margin |
| 2 | Google Business Profile and local search | System failed or owner is shopping now | High upfront, then free | Exclusive, compounding |
| 3 | Your own installed base | Upgrade, move, expansion | Low | Highest close rate in the trade |
| 4 | Newly formed businesses and fit-outs | First lease, first door, first key | Medium | Free public list, almost no competition |
| 5 | Builders, property managers, realtors | New build or tenant turnover | Medium | Slow to start, durable once built |
| 6 | Google Local Services Ads | Active search | Low | About $130 per lead for security |
| 7 | Paid search | Active search | Medium | $149 non-branded blended CPL |
| 8 | Marketplace leads (Angi, HomeAdvisor) | Active search, resold | Low | Review farm, not a pipeline |
| 9 | Door to door | None | High | Works only around completed installs |
Why cost per lead is the wrong place to start
SearchLight's February 2026 benchmark tracked $6.72M in Local Services Ads spend across 888 home services contractors and 126,650 leads. Blended cost per lead: $53. Electrical $39, HVAC $51, plumbing $57, with a 43.9% book rate and a $233 cost per paying customer.
Notice what is missing. There is no security or alarm category, because Google has not built one at the scale the trades have. Meanwhile a low voltage owner on r/lowvoltage reports paying roughly $130 per lead for security work and around $60 for AV, about two and a half times the blended benchmark, for a job whose install ticket is often smaller than an HVAC replacement.
Watch out
If you rank channels purely on cost per lead, security looks like a bad business. It is not. It is a business where the recurring revenue, not the install, carries the economics, which means the lead has to be priced against the account rather than the invoice. We covered that arithmetic in how to get more security alarm leads.
The practical consequence: rank sources by whether they arrive attached to a decision that is already being made.
1. Subcontracting for bigger integrators, MSPs and electrical contractors
This is the highest-yield source for most independent alarm and low voltage companies, and it is the one operators name first when other operators ask.
The mechanism is simple. Larger integrators, IT managed service providers and electrical contractors sell work they cannot or will not self-perform. When a client asks their MSP for cameras and card readers, the MSP already owns the relationship and the budget. Somebody has to do the install, and practitioners in r/lowvoltage are blunt about who. One puts it flatly: "MSPs have most of the work in the industry. Try to team up with a few of the larger ones." Another says "Talk to security integrators. They sub a lot of pulls out." A third describes how the relationship compounds: he helped out companies that were too busy, and "eventually they started just handing me jobs and I'd give them a kickback. In time I had loads of work." One operator reports averaging about 1,300 jobs a year through partnerships with larger companies while trying to build direct clients alongside.
The failure mode is worth naming. A tech who cold-visited local IT firms reported that every single business he visited said they sub out all their low voltage install work, and then none of them called him back. Dropping a card does not open the channel. What opens it is answering on a Friday afternoon and turning up on Monday, which makes the first few jobs an audition you accept at a thin number.
Two rules keep this channel safe. Bid adjacent scopes, because most security firms do not bid AV and most general contractors prefer one low voltage vendor on the sheet, so carrying data, AV and security together makes you the easy line item. And never let one partner exceed a third of your calendar, because they can insource the work, get acquired or go quiet with no warning.
2. Google Business Profile and local search
The best channel you can actually own, and in this trade it captures a specific trigger: something broke, or the owner is shopping right now.
The economics invert the partner channel. Slow to build, free to run, and nobody can resell the enquiry, reprice it or take it away. The operator who called Google Ads a waste of $1,500 said Google My Business had landed him local work, and that he was shifting effort to SEO because it "sure is nice landing new clients without paying for a lead or waiting for a referral."
What to do, in order:
- Complete every field, including service areas and every service line you actually sell (intrusion, access control, video, intercom, fire, service and repair).
- Get past 20 photos of real installs, and keep adding them.
- Turn on messaging and booking, then answer inside the hour.
- Build review velocity deliberately. Reviews are the input to both map rankings and close rate. Our guide on getting more Google reviews covers the ask that actually works.
- Publish the service pages a buyer searches at the moment of failure: alarm takeover, panel replacement, false alarm troubleshooting, access control for small business.
That last one matters more than it sounds. The searches that convert in security are repair and replacement searches, not "home security system" searches. Someone whose panel is beeping at 2am and whose original installer no longer answers is the highest-intent lead in this trade, and they are searching by name of problem.
We build the two channels nobody can reprice on you: local and AI search presence you own, and a follow-up system that converts what it brings in. If your profile and response times are already tight, we will say so and point at the channel gap instead of selling you a retainer.
3. Your own installed base
Every account you monitor is three future leads: an upgrade, a referral and a move.
The upgrade is the biggest and least worked. SafeHome's data shows where the spend is going: households plan to add cameras (28%), video doorbells (22%), alarm systems (11%) and access control (7%) in the next year. Camera and doorbell demand is roughly double alarm demand. If your base only hears from you when the invoice goes out, a big box retailer is serving the upgrade you should be doing.
The referral is the highest-closing lead in the trade, and it is not passive. An operator in Phoenix and Scottsdale who has watched this market closely says "every single company I know that is successful has a good referral network." He also names the trap: "You basically need to be sales fulltime. Its a whole different job which is why I failed." Referral flow is a job somebody has to own, not a thing that happens because your work is good.
The move is the one nobody catches. In the SafeHome switching data, 21% of people who changed providers did so because they moved homes, tied with better customer service. A customer moving out of your territory is a loss you cannot prevent. A customer moving within it is an install you should already be scheduled for, and that only happens if somebody calls when the house goes on the market.
4. Newly formed businesses and tenant fit-outs
Here is a free, public, monthly, state-level lead list that almost nobody in this trade works.
The US Census Bureau's Business Formation Statistics recorded 578,926 business applications in July 2026 on a seasonally adjusted basis, up 8.1% from June, with 29,959 of that cohort projected to become employer businesses within four quarters. The data is published monthly, broken out by state and region, and it is free.
Why this works: a business signing its first commercial lease has to solve access control, cameras and intrusion within weeks, usually against an insurance requirement or a landlord condition, and usually with no incumbent vendor. There is no switching cost because there is nothing to switch from.
An integrator in the Philadelphia tri-state area asked r/lowvoltage how to get past gatekeepers on property manager lists. The most useful answer pointed here: target newly registered businesses in their first 90 days, before they sign with anyone, and build relationships with commercial real estate agents representing tenants moving into new spaces, which the responder argued outperforms general contractor relationships for consistent pipeline.
Pair the formation data with two other public triggers in your county: new business licence filings and building permits for tenant improvements. That is a weekly call list of buyers with a deadline.
5. Builders, property managers and the move trigger
Same logic as the formation channel, applied to residential and multi-family.
An operator who has built his company this way describes the payoff precisely: he works with home builders and commercial project managers, and "you build those relationships up, and they will actively campaign for you to their customers." That is the distinguishing feature of this channel. A satisfied builder does not send you a lead, he sends you a standard specification on every house he puts up.
One honest caveat, because new mover marketing gets oversold. The firms selling mover lists cite figures like 72% of movers forming new brand relationships within 90 days, and those numbers come from companies whose business is selling you the list. The trend is also against them: US residential mobility fell to roughly 11% of people changing residence in 2024, a record low in data going back to 1948, down from about 14% a decade earlier. The move trigger is real and shrinking. Work it through builders, realtors and property managers rather than by renting a list.
6. Google Local Services Ads
The best paid starting point, with a caveat specific to this trade.
The mechanics favour a small operator: pay per lead rather than per click, Google sets the price, you cap the weekly budget, and you carry the Google Guaranteed badge, which matters disproportionately when a stranger is being let into someone's home or business. Contractors recover roughly 6% to 7% of spend in credits for disputed leads. Verification takes several weeks and requires licence and insurance checks, so start before you need it.
The caveat is price. Against a $53 blended benchmark and a $233 cost per paying customer across 888 contractors, the roughly $130 per lead operators report for security is a different proposition. It can still work, but only if you know what happens after the lead lands. Two contractors with identical cost per lead can end up at $180 or $440 per paying customer on book rate and close rate alone.
7. Paid search
Worth running once the free channels are working, and rarely before.
The benchmark numbers set expectations. In SearchLight's January 2026 Google Ads dataset covering 816 contractors and $14.9M in spend, non-branded search cost $149 per lead and $804 per paying customer, against $34 per lead and $104 per customer on branded terms. Blended, it was $104 per lead and $472 per customer.
That gap is the whole lesson. Branded search is cheap because the buyer already decided; you are paying a toll on demand you created elsewhere. Non-branded is where you pay to be considered, and in a trade where the buyer is not urgent, consideration is expensive.
The operator quoted earlier who burned about $1,500 with an agency on Google Ads had the sequence backwards. Fix the site and the follow-up first, then buy traffic into it.
Where paid search earns its price in security is narrow, service-shaped queries. Alarm takeover, panel replacement, commercial access control installation, false alarm repair. Not "home security."
8. Marketplace leads
Angi, HomeAdvisor and their equivalents are best understood as a review generation programme with a lead-shaped delivery mechanism.
Operators are consistent about the economics. One calls Angi worth it but says it still annoys him daily because of the price shoppers. Another is blunter: these platforms charge a high rate for the lead, "so you have little room to make profit when quoting a customer," and it is hardest on a new company. A third ran HomeAdvisor for about a year and said it "didn't lead to very much", but noted the customers he did win started recommending him.
That last clause is the actual value. The enquiry is resold, the margin is thin and you meet the buyer inside a price comparison. What you keep is reviews and a few referring customers, both of which feed the local search channel at position two. Run it with a review target and an exit date, not as a pipeline.
9. Door to door
Last, and only in one specific form.
Cold canvassing here sells against a market that already bought. 61% of US households own a security camera, up from 52% in 2024, and 49% of alarm owners installed it themselves against 42% who hired a professional. The door you knock has hardware, an app and an opinion about it, and among owners aged 18 to 44 self-installation is the majority.
The version that still works is re-canvassing after an install. Once a system is on a street, the neighbouring doors are a different conversation: you point at a specific house and a specific outcome rather than making a case about risk. The reference has to be real, though. A neighbour name-drop that gets fact-checked kills the block.
There is a genuine opening at those doors, but it is a service pitch, not a fear pitch. A DIY kit typically covers the front entry and nothing else. The back slider, the garage and the side gate are open, and the owner already proved they will spend on security by buying the kit.
The pitch that ranks dead last
One number should change how every one of these channels is worded.
Asked what drove their purchase, buyers ranked "professional install option" last of twelve factors, at 6%. Ease of use came first at 50%, monthly cost second at 46%, ease of self-installation third at 31%. Professional monitoring itself came ninth at 14%.
Almost every alarm company website leads with certified technicians and professional installation, which is competing for the least important thing on the list. It is not that install quality does not matter. It is that buyers assume it, so they hear nothing when you say it.
What the same data says they do care about, in their language: is this easy, what does it cost me monthly, and does it work when it matters. Rewrite your landing pages and your partner pitch around response time, verification that stops false alarm fines, and one system covering what their current setup leaves open.
Which three to five, by stage
Nobody should run all nine. Run three to five, because any single channel can be repriced or shut off without warning.
One or two techs. Integrator and MSP subcontracting, plus Google Business Profile. One pays this month, the other pays next year. Add marketplace leads only if you need review volume, with a hard exit date.
Steady crew, wanting predictability. Add the installed base motion, the cheapest revenue you will ever book, and start one formation or builder channel. Turn on Local Services Ads once you can measure book rate by source.
Sales capacity in place. Add paid search on narrow service queries and work the Business Formation Statistics list weekly. This is also where partner concentration needs a ceiling.
Skip door to door at every stage except as follow-up around completed installs.
Most alarm companies we talk to have two or three sources running and no idea which one produces the accounts that stay. We build the source tracking first, then fix the channel the numbers point at. Book a call and we will tell you which of these nine your market actually supports.
The metric to run this on
Stop comparing sources on cost per lead. Compare them on cost per dollar of new recurring monthly revenue, and on retention of the accounts each source produces.
An alarm business is not a job shop. A $130 lead that lands a monitored account on a multi year agreement and a $130 lead that produces a one off camera install are not the same object, and averaging them hides which channel is building the business. Partner work tends to produce larger installs with less recurring revenue. Local search and your installed base produce the monitored accounts that carry your valuation.
Three things to put in place this quarter:
- Tag source at intake, every time, no exceptions. If it lives in a notebook it will not get reviewed. Our guide on tracking where your leads come from covers the minimum setup.
- Report close rate and average new RMR by source quarterly. Most operators find their cheapest source is not their best one.
- Track attrition by source. Accounts sold under price pressure churn faster, which is exactly why the marketplace channel looks better on a lead report than on a valuation.
The trade is saturated, sticky and moving toward cameras and service. That is not a reason to advertise harder. It is a reason to put your effort where somebody has already been forced to decide, and to be the company they find at that moment.
