Announcement and advertising images can be
superimposed on the shooting screen for live
distribution and for recording onto an SD card. Up
to 50 image files can be saved in the camera
recorder and they can also be used as a slide show.
Zero Config Function n
The camera recorder can be automatically
detected using the Streamstar X series from
Streamstar connected to the same LAN, making it
easier to connect multiple units.
Control from RM-LP100 n
This camera recorder can be controlled by using a
remote camera controller RM-LP100. Control from
external devices is indicated as a tally display on
the LCD and VF.

be used to enable the same setup status for other
GY-HM250/GY-HM180/GY-HM170.
High Luminance Priority Mode n
Equipped with a high luminance priority recording
mode that reduces overexposure of brightly lit
images. By making the brightly lit areas high
contrast, the images will appear more natural.
Equipped with Histogram Function to
Check the Brightness of the Subject and
Assist in Determining Exposure Level
Allows users to check the overall trend of the
exposure level on a histogram and assists in
preventing overexposure and blocked-up
shadows.
High-Speed Recording Function
