Manage recorded files

Pearl Nano save recordings by default to the SD card (or SATA M.2 2280 SSD on Pearl Nano). When the SD card is full, new recordings overwrite the oldest recordings. You can not manually transfer recordings off the SD card to iOS or Windows systems.

There are a variety of ways to automatically transfer files from the system to local network storage. You can also manually select individual recordings to transfer or delete using the Admin panel.

Manage the recordings for a channel using the Admin panel

• Log in to the Admin panel as admin.

• Pearl Nano - From the Channel menu, select Recording. The Recording page opens.

• All recordings are listed and sorted by date.

Files that are part of the same recording session are listed one after another. Three dots appear between files of different recording sessions. The file currently being recorded (if applicable) is shown at the top of the list. It cannot be modified or downloaded until it has finished recording.

• If there are no recordings, a message indicates there are no recorded files for this channel.

• To download an individual file, select the recording filename to download it.

• To download multiple files, select the check box next to the recordings to download and then click Download Selected. The files are download as a .zip file containing the selected recordings.

• To rename a recorded file, select the edit icon next to the file name you want to change. Type the new file name and press Enter using your keyboard.

• To view a recorded file, click on the triangle Play button next to the file you want to play back. This will open the video file in an HTML5 player within the browser for viewing.

The Admin panel keeps track of the filename extension (i.e. .avi) so you do not need to include it when renaming the file.

• To delete a single recording, click the X icon to the right of a recording and click OK when prompted.

• To delete multiple recordings, check the check box beside the recordings you want to delete, then click Delete Selected. Click OK when prompted.

• To delete all recordings for the channel, click Delete All and click **OK **when prompted.

The list may not update immediately. You can refresh the list by reloading the Recording page.

Join recorded files together

After recording files on Pearl Nano, you can join two or more files together. This is useful when a recording exceeds the maximum recording time limit and the recording is split into multiple files. You can use the third-party tool called ffmpeg to join the files.

Download ffmpeg from the Internet and join multiple recorded files

• Download the files that you need from Pearl Nano and make sure you have the right paths and file names. For example:

C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi

• Use the command ffmpeg -i to specify the input file. For example:

ffmpeg -i C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi

• Repeat the process and specify the file you want to join to the first file. You can keep adding as many files as you want to join together. For example, specifying a second file looks like this:

ffmpeg -i C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi -i C:\Users\JoesComputer\downloads\Program_A_May11_12-26-14.avi

• Use the **-c copy **command to specify the output file. After the command, type in the location, file name and file extension that you want for the concatenated file. The full line looks like this:

ffmpeg -i C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi **-i **C:\Users\JoesComputer\downloads\Program_A_May11_12-26-14.avi -c copy C:\Users\JoesComputer\Desktop\Concatenated_File.avi

• After completing the process, you will be able to access your new file in the location you specified. The file moves straight from the first video into the second without a pause.

You can this process to join multiple files; however, the more files you join, the greater the chance that some audio desychronization can occur between the clips.
