• Has the camera been connected to a personal computer via a router
(via the Internet, for example)?
→ If UDP port transfer has not been set correctly, H.264 images cannot be
displayed.
H.264 can be transferred by HTTP when [Internet mode(Over HTTP)] is
set to [On].
• Has UDP communication been blocked by security software or a
firewall?
→ If [Internet mode(Over HTTP)] is [Off], H.264 is transferred by UDP.
→ Change the settings in the security software and firewall, and change
the settings to permit communications with your web browser.

Images stop in applications
that support High bandwidth

• When a personal computer and this unit are connected via a
commercially available USB LAN conversion adaptor, the images may
stop due to network problems on the personal computer side.
→ If this phenomena occurs, firstly disable the network adaptor that is
connecting the personal computer to this unit, then change [Streaming
mode] in [Video over IP] to [H.264]. After this, re‑enable the network
adaptor that you disabled and the images will be output when you
change the [Streaming mode] to [High bandwidth NDI].
