All Arlo video recordings are stored to the cloud, but you can connect a USB device to the Arlo Pro base station and use the USB device as a second location to store Arlo Wire-Free and Arlo Pro Wire-Free recordings locally. Local storage to a USB device cannot be used on its own as a substitute for cloud recording.
If you connect a USB device, the camera records to both the cloud and the USB device. If the camera and base station are powered on, but your Internet connection goes down, the camera continues to record to the USB device.
The Arlo app notifies you if the USB device is low on storage space or is full. If you select automatic overwrite, the oldest recordings are automatically deleted when available storage on the USB device is below 20%. Unrelated files that are not in the Arlo folder are not deleted by automatic overwrite.
- An Arlo Pro base station
- A USB flash drive or external hard drive with at least 100-200 MB of available space. If you are using best quality video settings, one hour of recordings is approximately 180 MB. If you have several Arlo cameras, have cameras in high-traffic areas, or have your cameras set to record long video segments, you might need more storage space.
Note: Network-attached storage (NAS) devices and drives with multiple partitions are not currently supported.
Do not use the Arlo Pro base station to format storage devices with more than 2 TB of storage capacity. The base station formats storage devices using the FAT32 file system, which supports a maximum of 2 TB of storage space. The formatting process reduces the capacity of larger storage devices to a maximum of 2 TB.
To set up local backup storage on an Arlo Pro base station:
- Plug the USB device into one of the two USB ports on the back of the Arlo Pro base station
- Launch the Arlo app or log in to your Arlo account at my.arlo.com
- Tap or click Settings > My Devices
- Tap or click the Arlo Pro base station into which you inserted the USB device
- Tap or click Local Storage
- If you see a green circle next to USB Device 1 and the status message Ready, skip to step 8
Note: If you already named your USB Device using a computer, the name displays instead of USB Device 1. If you insert a second unnamed USB device, it displays as USB Device 2.
If you see the message “Requires Formatting” next to USB Device 1 or USB Device 2, the USB device is not in the correct format (FAT32). You must format the USB device before you can use it for local storage.
Formatting the USB device erases all data from the device. If you want to keep any files that are on the USB device, copy those files to another location before you format the USB device. Do not use the Arlo Pro base station to format storage devices with more than 2 TB of storage capacity. The formatting process reduces the capacity of larger storage devices to a maximum of 2 TB.
- To delete all files on your USB device and format it for local video storage
- Tap or click > next to the USB device that you want to format
- Tap or click Format USB Device
- Wait for USB Device Status to change from Formatting to Ready
- If you do not want old videos to be deleted when your USB device is low on storage space, tap or click the slider next to Automatic Overwrite to turn it off. If automatic overwrite is turned off, the Arlo app notifies you when storage gets low so that you can enable local storage backup on a different USB device. If storage is completely full and automatic overwrite is turned off, videos are only recorded to the cloud until you turn on automatic overwrite or enable a different USB device
Warning: Do not remove the USB device while it is formatting. The USB device might become permanently unusable.
If you want a second USB device for when your first USB device is full, you can follow the same steps to add a second USB device, but you can only enable one USB device at a time.
