It is a Casino environment, so yes, highest settings and 30fps is required. I am only required to hold, I think ~7-10 days. However, recent events have the higher ups wanting the ability to hold up to 30 days. The price isn't really a concern at this juncture, I am just trying to get a better feel for how much storage space I will need.
I am recording at 640x480 De-interlace in the Geo MPEG4 Format.
