5. Ultra Image Quality Features

High Dynamic Range (HDR)

HDR solves the problem with over- or under-exposed images of scenes with both bright and
dark areas in the same picture. Your Arlo Ultra camera automatically determines when to use
HDR. HDR is optimized for outdoor environments. Your Ultra camera comes set to use HDR
automatically, but you can turn it on and off. See

Local 4K streaming and recording

4K means you can see more details in every image, even when zoomed in. Your Arlo Ultra
camera outputs 3840 x 2160 resolution at a 16 x 9 aspect ratio.
Your Arlo Ultra camera streams 4K while providing:
• 180-degree diagonal field of view that does real-time image de-warping
• Real-time high dynamic range (HDR)
• An integrated spotlight with dual noise-cancelling microphones
The Arlo Ultra system does all of this processing in parallel and in real time. Efficient video
encoding and battery optimization algorithms between the camera and the SmartHub allow
4K to work when your camera is running on battery power.
To use 4K streaming, you need an Arlo Ultra camera connected to an Arlo SmartHub VMB5000
or VMB4540 or an Arlo Base Station with Siren VMB4500 or VMB4000. For basic use of 4K, we
recommend an average upload bandwidth speed of 3 Mbps per Ultra camera.
You can stream 4K content without a subscription. You can use 4K by local live streaming or
recording 4K content. You can record onto a microSD card in the SmartHub VMB500 or onto
a USB device connected to the SmartHub VMB4540 or Base Station with Siren VMB4500 or
VMB4000. You can also purchase an add-on service to store 4K, motion-activated clips to the
Arlo Cloud for access anywhere your mobile app has a data connection.
