Do Wi-Fi security devices work during a power outage?

Wi-Fi security devices may stop working during a power outage if they rely on plug-in power, a router, or cloud connectivity. Some battery-powered devices may continue detecting activity locally, but remote alerts and app control can be limited if the router, modem, or internet service is offline. For important security functions, Houston homeowners and businesses should avoid relying only on Wi-Fi devices. A professionally configured system can include battery-supported devices and cellular communication when supported.
