About this app

DSGViewer is an application for viewing recording files of Hitachi's digital recorders for surveillance, DS-G series and DS-JH series.
Since the standard Viewer is only for the Windows version, I made an Android application by examining the recording file format on my own.

How to use
First, copy the file you want to view into your Android device. There are three types of file extensions that can be viewed: idx, jid, and gid. Other files in the folder containing those files are also required, so please copy them together.
Open the file from the button at the lower right of the app or from the "Open" menu in the upper right.
Play is the lower center PLAY button. The same button will stop during playback. The ">" and "<" buttons on the left and right of the play button are for 1 frame advance / return, and the next ">>" and "<<" are 10 frames advance / return.
Images can be sent to e-mail etc in jpeg format by "Share" in the upper right menu.
You can convert video to mpeg4 by "Save as mpeg4" in the menu. After selecting the menu, press the Convert button to create the converted file in the same folder as the original file.
Please open the converted file with your file manager.
