What Happens to Your Building’s Security When the Internet Goes Down?

Internet outages are a normal part of building life. A provider has a regional failure, a contractor cuts a line, a storm knocks out service for an afternoon. For most building systems, that’s an inconvenience.

For entry and access control, it can be much more. Residents may be stuck at the door, a guard may be unable to release an elevator, and incidents may go unrecorded. How your building behaves in that moment comes down to one design choice: whether your security system is cloud-only or runs on-premise.

Cloud-only vs. on-premise access control, in plain terms

Every access control system has to answer one question thousands of times a day: “Is this person allowed through this door right now?” The difference is where that question gets answered.

• Cloud-only systems answer it on the vendor’s servers. Door readers and entry panels at your building check in over the internet. Many keep a local copy of credentials for short outages, but how much still works varies widely by vendor.
• On-premise systems answer it on a server and controllers inside your building. The internet is used for remote access and backups, not for everyday decisions.
• Hybrid systems combine the two: decisions happen on-site, while remote management and backups use the cloud.

Neither approach is automatically wrong. But for multi-residential buildings, where hundreds of people rely on the front door and the guard desk every day, the on-site decision point matters.

What should keep working during an outage

When the connection drops, residents and staff shouldn’t notice. At a minimum, these functions should keep running with no internet at all:

• Doors, elevators and parking gates open for valid credentials.
• The guard station can release doors and elevators, and sees every alarm and call.
• Staff can add and remove residents and issue or cancel credentials on-site.
• Panic and intercom stations still reach the guard desk.
• Water leak alarms still sound, because a burst pipe doesn’t wait for your internet provider. Condoplex wireless water leak detection reports over a closed on-site network for exactly this reason.
• Every event is still logged, so the audit trail has no gaps.

The Condoplex access control system is designed around this list. Its controllers keep running on their own if the connection is lost, include onboard backup power, and use a failover server design: if one server fails, the next takes over automatically.

Where your residents’ data lives

An access control system holds a lot of personal information: names, suite numbers, phone numbers and a record of every time someone comes and goes. Condo corporations, associations and property managers are responsible for protecting that information under privacy law, such as PIPEDA in Canada and state privacy laws in the United States.

Before choosing a system, ask where that data is stored, who at the vendor can see it, and what happens to it if you ever switch providers. With an on-premise design, the data stays in your building’s own database, and a cloud backup protects it without handing it over. We cover the wider obligations in Condo Security Compliance: What Boards Need to Know.

You don’t have to give up remote management

The main reason buildings choose cloud-only systems is remote access: property managers want to manage credentials and review events from anywhere. That’s a fair requirement, but it doesn’t require moving the whole system to the cloud.

A hybrid design gives you both. Property Connect Plus lets authorized staff manage residents, credentials and events remotely, with mobile apps for residents and staff and cloud backup of the database, while every door decision is still made on-site. We explain how managers use this day to day in Remote Property Management: How Condo Boards and Managers Monitor Security From Anywhere.

Five questions to ask any access control vendor

1. Which functions keep working with no internet connection, and for how long?
2. Can staff add or remove a resident during an outage?
3. Where is resident data stored, and who can access it?
4. What happens if the server or controller itself fails?
5. If we change providers, how do we get our data back?

Clear answers to these questions matter as much as any feature list. If a vendor can’t answer them plainly, keep asking.

The bottom line

The internet will go down at your building eventually. The right system makes that a non-event: doors open, alarms sound, the guard stays in control, and your residents’ data never leaves your building.
