A quick overview of digital recording
Digital multiplex recorders work in exactly the same way as analogue multiplexers except that they
use hard disks to store video, instead of VCR tapes. Analogue recording uses time-lapse recording
to extend the length of time recorded onto 2 or 3-hour tape - recording fewer pictures every second.
Adjusting the number of pictures recorded every second also extends the length of time recorded
onto the hard disk of a unit. �owever, other factors also determine the amount of time that can be
stored on the disk of a digital multiplex recorder:
The image quality
The record rate
The hard disk capacity
