Motion recording stops after 8 sec

I have 2C Pro. It records motion but stops at 8 sec 99% of time. But I read that it will keep recording until motion stops or up to 2 min. How do I extent my 8 sec recording?

Go to the Power Manager setting and select either Optimal Surveillance or Customize Recording. If you select Customize, set the time you want, set 5 sec re-trigger. Make sure to Turn off “End clip early if motion stops”.
