How long can a 256 GB video card record?
In other words, with a 256 GB card the SGGCX2 can record continuoulsy for 1 day, 13 hours and 55 minutes before it will automatically start to overwrite the oldest footage. So with GB being the card size in GB, Mbps the bit rate in Mbps, and s the recording time in seconds, our formula is
How many Mbps does a second of video take?
Mbps means “Megabit per second”, so each second of video consumes 15 million bits. 256 GB are 256 Gigabyte, or 256 billion bytes. 1 byte has 8 bits, so the capacity in bits is 256*8=2048 Gbits. Divide this by 15 Mbits and the result is the number of seconds you can record.
