Introduction; Hardware Description And Connections; Standard (Blue) Unit - NETmc Marine 73fifty Series User Manual

1. Introduction

The 73fifty is a robust digital video recorder which is both simple-to-use and affordable. It is
capable of recording from a PAL, NTSC or SECAM video source and will automatically detect which
type of signal is present. (No re-configuration is necessary.) It can record for up to 120 hours
dependent on the bitrate selected. It is fully compatible with the NETmc Marine VideoTXT overlay
unit.
The standard (blue) 73fifty is housed in a 19" 1U rack-mountable case. Also available is a
73fiftyPeli version, which is supplied in its own robust Peli case for ease of transportation. This
can be supplied with or without its own monitor, and with or without internal built-in overlay.
The third option in the range is the 73fifty–Blackbox – designed for HSE recording requirements.
A new edition to the range is the 73fifty-videoPWR which is a combined digital video recorder
complete with camera and lamp controller, all supplied in the one Peli case for ease of
transportation.
