Hi Emmy and welcome to the forum!
The free version of NCS is the complete software. From camera 3 and above it is a red banner over thew image which is removed with a paid license.
-I have recorded a video but its record only 5 minutes video.
** In Settings --> Recording you can set the length of a recorded file. 5 minutes is the default.
- When I put the cam on recording with netcam on the next day I will daily press record button for each camera as I am using it, its the daily routine to press record button.
** Right-click on the video image and yu can select Schedule. There you can set up a schedule for the selected camera. Don´t forget to save this setting.
Is there any import option for recorded video?
Is there any other formate available without mp4.
** No, mp4 is the format that is used for the stored files.
