==Camera mounting recommendation==
Camera location:
* To maximize the field of view, the camera should be mounted in the middle of the front windshield so that an even field of view for the sides of the vehicle is recorded. We recommend you mount the Dual Cam near the rearview mirror area.
* We always recommend angling the lens slightly upwards so that video footage displays about 60% road and 40% sky. This angle offers a good balance of exposure and details.
* View footage from SD card while mounting the Dual Cam so you can select what position and angle you prefer the Dual Cam to be set at.
Rear camera adjusting:
* Gently remove the cover from the case of the top camera. After the cover is removed you will see the screw.
* Unscrew it and rotate the rear camera to adjust the better view of the cabin. The rear camera contains infrareds on it.
* Put the cover back on the camera.
Connecting power source:
* Due to high camera power consumption we always recommend connecting the camera to the vehicle ignition. The camera start-up in 2-3 seconds when vehicle ignition goes ON.
* Camera ground (Black cable) must be connected to the same (common) Ground wire as FMx125 device.
* Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.

==Video file conversation==
===Video files and conversion===
Videos downloaded from the camera are in the raw h265 format. By default, they could be viewed using the ZMVideoPlayer program in the h265 format. If the videos are needed in a more common format, they can be converted.
===Video conversion example and settings===
For converting DualCam h265 videos to a more popular mp4 video format, a free open-source converter FFmpeg is used in the example. Although any other converter from h265 would work as well.
To convert DualCam video properly, the converter has to know the frame rate of the video. The frame rate is configured as Config Id: 66003 and could be either 20, 25, or 30 FPS. That same value could be obtained by using the metadata command (see more details at [[Teltonika_DualCam#Communication_protocol|File metadata response]] ('''CMD ID 0x000B''')).
Recommended parameters using the FFmpeg for the conversion:
'''ffmpeg -r <fps> -i <input>.h265 -ss 00:00:0.9 -c:a copy -c:v libx264 <output>.mp4'''
<fps> - configured frame rate of the video;
<input> - file name of the video file from the camera;
<output> - file name of the video that will be converted to mp4.
