Thank you for choosing the DVR1A. It converts analogue NTSC or PAL video to digital images and records them on
a removable hard disk drive. Digitally recorded video has several advantages over analogue video recorded on tape.
There is no need to adjust tracking. Digital video can be indexed by time schedule or events and you can instantly
view video after selecting the time or event. You can freeze frames, fast-forward, fast-reverse, slow-forward and
slow-reverse without image streaking or tearing. It can be used as a replacement for a time-lapse VCR in a security
installation.
