Thank you for choosing this high quality Digital Multiplex Recorder. The DMR converts analog
NTSC or PAL video to digital i ages and records the to a re ovable hard disk drive. Digitally
recorded video has any advantages co pared to analog video recorded on tape. There is no
need to adjust tracking. Digital video can be indexed by ti e schedule or events, and you can
instantly view video after selecting the ti e or event. You can freeze fra es, fast-forward, fast-
reverse, slow-forward, and slow-reverse without i age streaking or tearing. It can be used as a
replace ent for both a ti e-lapse VCR and a ultiplexer in a security installation.
