About this product
Four devices in a home network go down first when power dies: the ONT, the router, the NVR and the door controller. All of them run on low-current DC between 5V and 12V, which is exactly what one multi-voltage UPS adapter covers. When the grid fails, the battery takes over and the whole chain stays online. Before ordering, do two things: check the rated voltage and current printed on each device's original adapter, and count how many devices need backup. Mismatched voltage is the most common failure with this kind of product — confirm first, order second.
