What is a TDX file?
Video information file created by D-TEG CCTV (closed-circuit television) DVRs (digital video recorders); saved with other information files as well as the video recording file itself; must be present with the original video file for video playback.
The video captured with TDX files can only be played back using the player bundled with the D-TEG DVR.
