Outline of product

The successor to the AB-4838/AC-4829-D, the new and improved AB-4852/AC-4851 is still small and lightweight,
but now with more features that improve functionality and open new avenues for use.
It can shoot in 8K8K 60p, 8K4K 120p, and 8K2K 240p (Dual 4K), giving users flexibility for any kind of situation.
One of the most exciting features is the ability to transmit signals between the camera head and CCU without
the use of any additional optical converters, simplifying set up and reducing failure points.
The camera head and CCU communicate through QSFP, enabling them to be placed up to 2km apart.
This is ideal for use in large areas like stadiums, outdoor arenas, or racetracks. Users can also connect directly
to the camera head through a viewfinder to directly check the camera image.
The L-mount gives users a wider variety of lens options, allowing this 8K multipurpose camera
to be used in many different industries and markets.

Use Cases

Stadiums and Other Large VenuesOB Vans/Mobile Broadcast UnitsHigh-Reliability Broadcast Environments
With the extra distance provided by
the direct single-mode fiber, this unit
makes filming in a wider area a breeze.
One clean line from camera to control
with no extra boxes in between gives
users fewer failure points and a much
easier time setting up. Using an
adapter plug, you can connect from
the venue to the control room using
existing SMPTE fiber.
With its compact size, AB-4852 is ideal
for use in constricting conditions,
while also reducing power
requirements and cable clutter,
essential when mobile. Its ability to be
setup/torn down quickly makes it
perfect when time is of the essence.
As the CCU can output both 2SI and
SQD signals(future upgrade), an
external converter is not required.
When downtime is unacceptable, the
signal path for the AB-4852 is more
direct, with fewer failure points for
potential issues.

Features

■Long Distance Operation
Being able to place the camera head so far from the CCU makes operation in large areas
easier than ever before. Now even the most remote locations are within reach.

■Return Video
Using the newly added return video function, users now have the option to check the
camera angle and other functions directly from the camera head by connecting to a
viewfinder or monitor.

■Simpler System
This new system eliminates the need for external converter units, creating a cleaner
signal chain with fewer failure points. This also reduces the overall cost of the system
(planned upgrade).
