The Integrator has an internal memory space of about 54 Gb.
This memory card has enough space to store up to 97.000 photos or 13.5 hours of video. The Integrator need to run non-stop for approximately 12 hours to store this amount of data.
Please keep in mind you need external power to run for such extended periods of time.
To see how much memory space is left go to 'capture' in the Integrator menu (see picture below).
