A video I made that demonstrates the basics of using the ZoneMinder security suite.

It turns out that a significant amount of memory is required for scanning and decompressing images (go figure). What I did  not know is that the amount of allocated memory can only grow to a certain point before it hits the maximum amount for a given program. The ZoneMinder FAQ was very helpful in resolving the matter.  Basically you issue a simple command to up the amount of memory allowed for each program:

echo 134217728 >/proc/sys/kernel/shmall
echo 134217728 >/proc/sys/kernel/shmmax
