Version 1.2.2
For Android Mobile and Tablet
* All viewable components like camera view, buttons, location data and other widget you see on the screen are recorded in video file. So don't need to use separate SQL database to store location data
This app records your journey in multiple video files format mp4.
This app can capture normal photo, but can not capture photo while recording
All photos taken by this app contain Exif information (GPS data) if GPS is available. Exif data is used for locating photo on Google map later.
This app uses the way of looped recording on multiple video files, oldest file will be removed and replaced by newest file (for saving the space of device's storage)
When you start the app, the app will calculate the duration and number of video files for the queue to perform the looped recording. This calculation depends on free space storage and file size per minute (FSPM). FSPM is very different on different devices and with different video bit rate and varied from some Mega bytes to about 20 Mega bytes/minute (see statistics)
By this way of calculation we have a new recording session with the following parameters
Min number of files: 2
Max number of files: 6
All the files has the same duration of 1 to 10 minutes
Min time : 2x1=2 minutes and Max time : 6x10=60 minutes (an hour)
If your device does not have much space storage and you want to start new recording session, so you must remove all files of prior session to get free space storage
Managements:
1. Recording manager - main screen
2. Video and Image Manager - replaying video, viewing images,send , modify ...
Settings: easily and simply
1. Measure unit of velocity: Km/h or MPH
2. Allowing audio recording or not
3. Acceleration threshold: 2.5 m/s² or 3.0 m/s² or 3.5 m/s²
Deleting Files:
The GPS data are attached at the video file if GPS device is turned ON and active. So You must delete video files by using rightly the context menu of Dashcam Pro, else you will leave GPS Data part without deleted from the database. (if you use Gallery to remove files, it can not remove GPS data part attached and if it happened the only way of repair is the uninstalling app and reinstalling it
