The Start Recording button on the Preview Control Bar can be used to record the preview from the selected video device. The recording would go on till you stop it manually. Monitoring with alerts, scheduling and other options are de-activated while you record manually. The only activities you can perform while manual recording are taking photos and streaming.

While recording is going on, the Start Recording button changes to a blinking Stop Recording button .

All settings that you configure for the Video/Audio Recording alert will apply to manual recording.

Though recording will go on till you stop it manually, it will stop if the specified space limit (on the drive where the recordings would be stored) is reached. This limit can be set from Tools menu > Options > General tab > Additional Storage Constraints.

You can see the Monitoring Log for the timing of events such as starting and stopping of manual recordings. Go to the Recordings tab to preview the manual recordings and photos taken.
