Hard Drive space requirements for recording
-
How much hard drive space per camera do I need to record for images up to 640X480?
What formula would I use to calculate hard drive space requirements for different cameras at different resolutions.
I would like to keep images up to a one month span if possible. -
A 640x480 still image is approximately 8kb in size. Another way to say this is that 125 still images would take up about 1 megabyte. A 1024x768 image is about 20kb, or 50 images per megabyte.
Assuming you took 100 pictures per day for 30 days at 1024x768, these 3000 images would only need 60 megabytes of storage space. Even with 8 cameras, you could still store one month's images in half a gigabyte (at 100 images per day).
