What to Ask Before Choosing an Intercom for Your Home or Building

Picking an intercom is one of those decisions people research for weeks and still get wrong, because the spec sheets don’t ask the questions that actually matter. We install and repair intercoms all over LA, and before we recommend anything, we walk every client through the same short list. Here it is, along with what real buildings get burned by when they skip it.

The 8 Questions We Ask Every Client

Each of these kills or crowns a system. Here’s why.

1. Phone call or app?

This is the people question, and it decides more installs than any spec. Older residents want the intercom to ring a normal phone they already answer. Younger residents want an app with video and a doorbell notification. In a mixed building, an app-only system quietly locks out the residents who won’t use it, and you’ll hear about it at the next board meeting. The best answer for most buildings is a system that does both: app for those who want it, a plain phone call for those who don’t. If a product only does one, make sure it’s the one your actual residents will answer.

2. Audio or video?

Audio-only intercoms still work fine for “who is it, come up.” But video changes behavior: you stop buzzing in anyone who mumbles “delivery,” you have a face when a package disappears, and residents screen solicitors without opening anything. The costs are real too. Video needs a camera position with decent light, more bandwidth, and usually a network connection at the entry. Our rule: for a gate or a building entrance, video earns its cost within the first incident. For an interior suite door, audio may be all you need.

3. Door, gate, or both?

A front door install is simple: the intercom fires an electric strike a few feet away. A driveway gate is a different project. The intercom has to trigger a gate operator, often across a long underground wire run, and many properties also need a separate relay for a pedestrian gate. Count your openings before you shop. A system with one relay can’t run a vehicle gate and a walk-in gate independently, and “we’ll just wire them together” creates exactly the stuck-open service calls we get paid to untangle.

4. What wiring exists today?

The building decides the budget here. A 1928 walk-up with a single phone pair at the entry is a retrofit project; new construction with Cat6 to the entry is plug and play. Between those extremes sit most LA buildings: some old intercom wire, maybe conduit you can reuse, maybe nothing. Before you pick a product, know what’s in the wall. Reusing existing wire can save real money, and knowing you’ll need to trench to the gate changes which systems even make sense.

5. Monthly fees: yes or never?

Cloud systems charge per month for the app calling, remote management, and hosting. Some boards happily pay it because the features save more than they cost. Others refuse subscriptions on principle, and that’s a legitimate position. What we insist on: decide this before you fall in love with a product. Half the intercom market is subscription-based now, and finding out at the proposal stage that your board won’t approve recurring fees sends everyone back to square one.

6. Who manages tenants and codes?

In a building with turnover, directory management is the feature you’ll touch weekly, and it’s the one nobody asks about in the showroom. Old-school systems get reprogrammed at the panel or through desktop software with a password someone wrote down in 2019. Cloud systems let a property manager add or remove a tenant from a laptop in five minutes. If people move in and out of your property regularly, weigh remote management above almost everything else.

7. Do you need a record of who came in?

After a break-in or a package theft, the first question is “who buzzed them in, and when.” Some systems log every call, code, and door release per person. Others keep nothing you can pull afterward. If your building cares about accountability (HOAs, mixed commercial, anywhere with vendor codes floating around), make event logging a requirement, and rotate those vendor codes on a schedule. This is question 7 for a reason: nobody thinks about it until the day they need it badly.

8. What happens when the internet or phone line dies?

Every intercom depends on something: a copper phone line, a cellular module, your Wi-Fi, or a hardwired network. Copper is being retired across the country, Wi-Fi drops when a neighbor changes routers, and cellular needs signal at the entry. Ask the failure question before you buy: when the connection dies, does the gate stay secure, do codes still work, does the system recover on its own? Wired network connections fail the least, which is why we push for them on every install where conduit exists.

Real Buildings Asking the Right (and Wrong) Questions

The 11-unit condo that wrote a perfect requirements list

A small condo board on r/accesscontrol posted a shopping list we’d frame and hang on the wall: calls to regular cell phones (not app-only, because some owners have older phones), wired reliability so it works when the internet goes out, real tamper resistance, and operating fees with a hard ceiling.

Our take: that’s exactly how to shop. Notice what’s NOT on their list: brand names. They defined how the building actually lives (older owners, phone calls, reliability first) and let the product follow. When a board starts with the answers to our 8 questions, the right system picks itself.

The house that got rid of its landline and orphaned the intercom

A tech on r/accesscontrol had a client whose telephone-entry intercom had nothing left to ring after the house switched every phone to internet calling.

Our take: this is question 8 arriving in real life. Telephone entry systems built the industry, but the phone world they plugged into is being retired. If you’re choosing a system today, ask what it depends on: a copper line, a cellular module, your Wi-Fi, or a hardwired network. Each fails differently, and each costs differently to keep alive for the next ten years.

The renter who wanted the buzzer to ring two phones

A New Yorker asked whether their building buzzer could ring a Google Voice number so both they and their spouse would get visitor calls.

Our take: a completely reasonable ask that older systems handle badly and modern ones handle natively. Apps ring every phone in the household by design; virtual numbers on telephone-entry systems sometimes can’t send the unlock tone back. If “we both want to answer the gate” matters to you, that’s a question 1 conversation, and it usually points toward an IP video intercom like DoorBird.

What the pros complain about when nobody’s listening

A long industry thread on r/accesscontrol vents about multi-unit intercom weak points: flimsy cabinet locks, outdated card readers, poor accessibility for hearing and vision impaired residents, and vendors that don’t integrate with anything.

Our take: you don’t need to understand every acronym in that thread. The takeaway for a building owner: physical security of the unit itself, reader technology that isn’t trivially cloned, and accessibility for your actual residents are real differences between products that all look similar in a brochure. This is exactly the stuff we flag during a site visit.

How the Answers Map to Systems

Rough guide from our install experience: phone-call-first buildings with simple needs still do well with telephone entry like DoorKing, especially with a cellular module replacing the dying landline. Buildings that want video, apps, and remote management land on IP systems like DoorBird or ButterflyMX. Single-family homes with gates usually want an IP video intercom wired to the gate operator, with a keypad for the pool guy and deliveries. And every building with move-ins and move-outs should weigh remote directory management more heavily than any other feature; it’s the one you’ll use weekly.
