How do I record 4K videos to a local storage device?

With Arlo Ultra or Ultra 2 and a compatible SmartHub or base station, you can save 4K videos directly to a microSD card or USB device. This provides a solution if you don’t want your Arlo video recordings to touch the Arlo cloud, or in the event that your Arlo SmartHub or base station disconnects from the Internet.

What you need

You need the following to record locally in 4K:

  • An Arlo Ultra or Ultra 2 camera
  • One of the following:
    • An Arlo Smart Elite plan
    • No Arlo Smart subscription
    • A 4K-compatible legacy Arlo Smart subscription

Note: Due to hardware limitations, Arlo Ultra cameras cannot stream to the cloud in 2K and simultaneously record locally in quality higher than 2K. However, Arlo Ultra can simultaneously stream to the cloud and locally in 4K.

  • A 4K-compatible Arlo SmartHub or base station
  • A compatible microSD card or USB device
    • VMB5000 accepts microSD cards, microSDHC, or microSDXC. We recommend that you use a microSD card with a minimum of 16 GB capacity, Speed Class 10, UHS1, V10. The Arlo SmartHub supports up to class 10 UHS-3 V90 class microSD cards.
    • VMB4540, VMB4500, and VMB4000 accept USB 2.0 compatible flash drives or external hard drives with a Type-A connector and at least 16GB of available space.
