A filename must be included. .PARAMETER Format The format in which the recording should be exported. The default format is matroska. Most cameras only support the matroska format. .EXAMPLE Export-AxisRecording -Device 192.168.1.100 -StartTime (Get-Date "2022-01-01 00:00:00") -StopTime (Get-Date "2022-01-01 01:00:00") -FilePath "C:\Recordings\recording.mkv" This example exports a recording from the Axis device that occurred between January 1, 2022, 00:00:00 and January 1, 2022, 01:00:00. The exported recording will be saved as "C:\Recordings\recording.mkv". #> function Export-AxisRecording { [cmdletbinding( SupportsShouldProcess = $true, ConfirmImpact='high' )] Param( [Parameter(Mandatory)] [String]$Device, [Parameter(Mandatory)] [DateTime]$StartTime, [Parameter(Mandatory)] [DateTime]$StopTime, [Parameter(Mandatory)] [String]$FilePath, [Parameter()] [String]$Format="matroska" ) if($FilePath -notmatch "\.[A-Z1-9]{3}") { throw "Invalid Path.
