+The tsPartDuration parameter is the duration of the chunk the dvr recorder will write. By default, the value is 2000 ms. Thus, every 2s, the dvr-recorder will write a chunk of 2s.
+You can change this parameter in order to decrease the NAS loading (i.e 10000ms).
+Increasing the value of this parameter will delay the live output stream. So, if you change the value from 2s to 10s. The live will be delayed of 8s.
