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.
