Guide by an independent Vivint Authorized Dealer
Does Vivint Need Wi-Fi?
No, Vivint does not need Wi-Fi for alarm monitoring, because the Smart Hub has a built-in cellular radio that sends alarm signals to the monitoring centre when the internet is down; Wi-Fi is needed for camera streaming, video storage, and remote app control. This guide lists what works on cellular alone, what needs Wi-Fi, the 24-hour battery backup during power outages, and the Wi-Fi requirements for cameras.

What Works on Vivint Without Wi-Fi?
Without Wi-Fi, 4 Vivint functions keep working over the hub's cellular radio: intrusion, fire, and CO alarm signalling to the monitoring centre, arming and disarming at the panel, emergency dispatch, and basic app notifications of alarm events.
What Needs Wi-Fi on a Vivint System?
4 Vivint functions need Wi-Fi: live camera streaming, cloud and Smart Drive video recording, two-way talk through cameras, and smart home automations that run through the app rather than the hub.

|---|---|---|
| Alarm signals to monitoring | Yes | Yes |
| Arm/disarm at panel | Yes | Yes |
| Alarm notifications in app | Yes | Yes |
| Live camera view and recording | No | Yes |

What Works During a Power Outage?
During a power outage the Smart Hub runs on its battery for up to 24 hours (Smart Hub Pro 2; earlier hubs 4 to 6 hours), sensors run on their own batteries, and alarm monitoring continues over cellular; cameras, Wi-Fi routers, and plug-in devices stop until power returns.
The Vivint power outage guide covers battery life by device.
What Wi-Fi Does Vivint Require?
Vivint cameras require a 2.4 GHz or 5 GHz Wi-Fi network with a signal strong enough at each camera location, which the technician measures during the installation walkthrough; homes with weak outdoor coverage add a mesh node near exterior cameras.
