You can record to an SD card if your camera has an SD card slot
You will have to reformat the card before you can use it
First make sure the SD card is in the camera before you follow these steps.
Open the Alcidae App, for the Camera that has an SD card installed
1.) press on the camera still image to bring up live view
2.) press on the top right gear icon
3.) press Advanced Settings
4.) press Restart & Reset and press format SD card
Then go back one screen to Advanced Settings, then go to SD Card Settings to create a schedule
This formats an SD card installed in one camera and sets a schedule for recording on that camera
