Feature summary
• Simple and intuitive control: Start the recording function from HiTeach software.
• No shooting area constraints: A Bluetooth microphone with infrared sensor
allows camera to follow teacher’s movement and capture every moment.
• Tag key concepts: students can use their IRS clickers to mark the parts which they
consider them important or difficult for review purposes
• Automatically print Logo on the video
• The recorded video can be uploaded to private FTP or ezCMS on IES for
management and review without time and space limitations.
-
Storage and management: ezCMS• Videos recorded by ezStation can automatically be uploaded to and saved on ezCMS
(Content Management System), which is an add-on module of our private cloud service,
called IES (Instruction Expert System).
• Teachers can organize videos
by the content, types of
materials, or privacy, and
assign videos to whole class or
specific students to review.
• When integrated with HiTeach,
the video can be consolidated
with other instructional
materials to create a
completed remediation lesson.
