m. Loop Recording:
The DVR shall record continuously onto the removable hard
drive. The system recognizes when the available storage capacity for
surveillance images has reached capacity and automatically begins to purge the
oldest data in sequential fashion, making room for additional images without
operator intervention. Images that are tagged due to the activation of the
system’s inputs are protected from automatic overwriting until the relevant
images are manually deleted, or until all available space is filled with tagged
images, at which time the system performs a “first-in, first-out” (FIFO) overwrite.

n. Event Tagging: The DVR shall tag events when a system input, such as a
panicbutton, is activated. Tagged events are stored on the hard drive. When
retieved, the tagged events shall be easily identifiable and will remain saved for a
programmable period of time before being overwritten.
