I'm interested why my calculations show the built in memory in a much more favorable light than the examples above. I'm wondering if some calculations are mixing up the bitrate (for example 10mbps - i.e. 10 Mega bits per second) with MBps which would be Mega Bytes Per Second. In the example which C4rc4M noted above he stated that 1GB = 1024mb = 1024/10 - which it doesn't. 1GB is 1 GigaByte which is 1024MB (megabytes) not 1024mb (which is Megabits). The difference in the capitalisation of the bitrate figures is important here as there are 8 bits in a byte so the calculations above are out by a factor of 8. Writing at 10mbps, 1GB would take over 13 minutes to write, not 1 minute 43 seconds. This also means the camera at 10mbps would be writing a total of just over 105GB in a day, not the 834GB noted.
I stand corrected.
