Quick answer: A Hawaii business security system survives a hurricane if four things are true before the storm arrives: footage is stored on the cameras and in the cloud rather than on a ground-floor NVR, the network has a cellular backup path, the cameras, controllers, and alarm panel are on battery or UPS power sized for at least the first several hours, and someone can see the property remotely from wherever they've evacuated to. Most of that is a configuration and planning exercise you can complete in about an hour, and the checklist at the end of this guide walks through it.
Hurricane Lowell made the case for this guide the week it was written. After reaching Category 5 twice south of the islands, Lowell passed about 80 miles west of Kauai on the night of September 7, 2026, as a Category 2 — no landfall, but 85 mph gusts, coastal evacuations, closed roads, and nearly 92% of Kauai Island Utility Cooperative's members without power by Tuesday morning, with restoration expected to take several days or longer. Outages spread to Oahu as well. The HI-EMA checklist every Hawaii business gets each June covers water, generators, and shutters. It says nothing about the camera system. This guide fills that gap, from a locally owned Honolulu team that designs cloud-based security for businesses on every island.
What happens to your security cameras when a hurricane knocks out power?
If your cameras record to an NVR, they stop recording the moment the building loses power, and the recordings you already have are only as safe as the closet the NVR sits in. Traditional systems fail in two stages during a storm. First the outage stops new recording, which means the hours when looting, storm damage, and trespassing actually happen are the hours with no footage. Then, if the ground floor floods or the roof gives up, the NVR itself is lost — along with every clip from before the storm that you would have needed for an insurance claim. Kauai businesses learned that lesson in Iniki in 1992, and Hilo businesses relearned it when Hurricane Lane's rain flooded ground floors in 2018.
Cloud-managed cameras fail differently. Each Verkada camera stores its own footage onboard — weeks to a year of retention depending on the model — and syncs to the cloud, so pre-storm footage already lives off-island and a camera that survives the wind keeps a local copy of everything it saw. If the internet drops but power holds, the camera keeps recording to itself and uploads when the connection returns. The failure point moves from a single box in a closet to each individual camera, which is exactly the redundancy you want when part of a building may not make it.
Power is still the constraint. Cameras draw power over the same Ethernet cable that carries their data, so a UPS on the PoE switch keeps every camera on that switch recording through the first hours of an outage. For a small site, a modest rack UPS buys two to four hours; a larger property will size a UPS or generator circuit for the switch, the network gear, and the door controllers together. The point of the UPS is not to ride out a three-day outage — it's to keep the cameras recording through the storm itself and the first hours after, when nobody else is watching.
Does a cloud security camera system work during a hurricane if the internet goes down?
Yes, as long as it has power — and it keeps working remotely if it has a cellular path. Because Verkada cameras record to onboard storage, a downed fiber line doesn't stop them; it only stops you from watching live until the connection is back. To keep remote visibility during the outage, add a cellular gateway as a backup path. When the wired connection fails, the gateway moves the site's cameras, sensors, and door controllers onto LTE. The bandwidth math works because Verkada cameras stream only when someone is watching or an event needs review, so a cellular link that would choke on a conventional NVR system handles a cloud site comfortably.
For properties with no power at all after a storm — a damaged building, a jobsite, a lot with downed lines — the solar-and-battery CR63-E remote camera runs on its own dual-SIM LTE modem and its own power, the same build we recommend for Hawaii construction sites. Several businesses keep one or two on hand specifically as post-storm coverage: they go up on a fence post the morning after and report to the same dashboard as the permanent cameras.
Will the burglar alarm still call for help if the phone lines and power are out?
A modern cloud alarm panel will; a legacy panel on a copper phone line usually won't. Verkada's alarm panels are built for exactly this: the BP52 carries dual backup batteries and an LTE communicator, and the compact BP32 has built-in LTE and a 30-hour internal battery, so an armed system keeps talking to the monitoring center after the building's power and internet are gone. A camera-verified alarm matters more during a storm, not less, because police response is triaged. Dispatchers are handling downed lines, flooding, and medical calls; an unverified door sensor from a business with no one on site goes to the bottom of the list, while a monitoring agent watching live video of someone inside your store gets a different reception. Our alarm systems page covers how video verification and monitoring fit together.
Two configuration notes before a storm. Arm the system before you evacuate and confirm the LTE path in the dashboard; a panel that has been sitting on Wi-Fi only will show it. And if your property uses live video monitoring, tell the monitoring provider the building will be unoccupied and for how long, so any person on site after hours is treated as an intruder rather than a late employee.
Do access-controlled doors lock or unlock when the power fails?
It depends on the door hardware, not the software — and it's the question most Hawaii businesses can't answer until they check. Magnetic locks are fail-safe: they release when power is lost, which is what fire and life-safety codes require on egress doors, and it also means a maglock-secured back door is open once the building goes dark. Electric strikes and most electrified lever sets are fail-secure: they stay locked without power and can still be opened from inside by the handle. Battery-powered wireless locks keep working on their own batteries. Walk your doors before the season and know which is which; the answer determines whether "power's out" means "the building is open."
The controllers themselves are the easy part. Verkada door controllers keep making unlock decisions locally if the cloud connection drops, so credentials and schedules keep working through an internet outage. Put the controllers and the PoE switch that powers the readers on the same UPS as the cameras, and the doors ride through the first hours exactly as they do on a normal day. A storm is also a good moment for remote unlock: when a crew needs into a closed building the morning after, a manager can open the door from a phone on another island rather than driving across debris to meet them.
What should be on a hurricane-season security checklist for a Hawaii business?
The following list covers most properties and takes about an hour, ideally in June and again when a storm is forecast. Central Pacific hurricane season runs June 1 through November 30 and peaks from August through October; NOAA's 2026 outlook called for a 70% chance of an above-normal season with five to thirteen tropical cyclones, and Lowell was the fourteenth named storm of the wider Pacific season.
- Confirm every camera shows healthy and recording in the dashboard. A camera that has been offline since July won't help you in September. Check cloud backup is enabled and retention is set as long as your license allows.
- Confirm the UPS is holding a charge and know its runtime. Test it by pulling the plug for two minutes. If the cameras drop, the switch isn't on it.
- Verify the cellular backup path. Fail the wired connection on purpose and watch the site come back over LTE. If you don't have a gateway, this is the single highest-value addition before the season.
- Know your door hardware. Label each door fail-safe or fail-secure, and decide in advance which doors get manually locked before evacuation.
- Arm the alarm and confirm the LTE and battery status before leaving. Notify your monitoring provider that the site is unoccupied.
- Set up remote access for the people who'll need it. Make sure the owner, the manager, and whoever is off-island have working logins on their phones, with two-factor set up on a device they'll actually have with them.
- Capture "before" footage. Walk the property with your phone and clip the exterior cameras' current view. Timestamped before-and-after video shortens claims conversations, though what a carrier accepts varies by policy.
- Clip anything you need for a claim within the retention window, and share clips by link rather than exporting to a drive that might be in the flooded office.
Multi-island operators benefit the most from this. A retailer with stores in Lihue, Kahului, and Kapolei can watch all three from a Honolulu kitchen table or a mainland hotel room, see which locations have power by which cameras are online, and decide where to send people first — the same visibility we describe for Maui and neighbor-island businesses. None of it guarantees a system will survive a direct hit; the goal is that the things you can control are already handled when the watches go up.
Frequently Asked Questions
Do cloud security cameras keep recording during a power outage in Hawaii? Only if they still have power. Verkada cameras are powered over Ethernet, so a UPS on the PoE switch keeps them recording onboard through the first hours of an outage, and existing footage is already stored on the camera and in the cloud rather than on a single NVR that may flood.
Will my alarm system still work if the internet and phone lines are down? A Verkada alarm panel with LTE backup and internal batteries keeps reporting to the monitoring center after wired internet and power are gone. A legacy panel that depends on a copper phone line or Wi-Fi alone typically won't.
What happens to my access-controlled doors during a hurricane? Verkada door controllers keep working locally without an internet connection, but the door hardware decides what happens without power: magnetic locks release (fail-safe), electric strikes stay locked (fail-secure), and battery wireless locks keep running. Know which each door uses before the season.
Can I watch my business remotely if I evacuate to another island or the mainland? Yes. Cloud-managed cameras, doors, and alarms are viewable from any phone or computer with the right login, and a cellular gateway keeps the site online if the wired connection fails.
How long should I keep footage after a storm for an insurance claim? Long enough to clip and share what you need. Verkada retention runs from weeks to a year depending on camera model and license, and clips can be shared by link with an adjuster in seconds; what a carrier requires varies by policy, so confirm with your broker.
