DVR Tral 1-22

DVR Tral 1-22 is a stand-alone digital video recorder (DVR) with removable hard drive. It records and provides access to data from 4 analog (PAL/NTSC) asynchronous video sources and 2 independent audio sources in MPEG-4 format using a removable 2.5-inch hard disk.

Overview

DVR Tral 1-22 can store up to 4 weeks of archived data without overwriting.

DVR Tral 1-22 is different from other similar devices, as it uses a special unit based on the AMD Alchemy Au1000 processor with the MIPS32 instruction set. This technology enabled us to create a reliable portable device with high performance and low power consumption (7 W). DVR Tral 1-22 operates under OS Linux 2.4 providing high reliability for embedded systems.

DVR Tral 1-22 is special because of its small size and use of natural cooling. These factors lead to substantial extension of its application areas. Automatic teller machines, train cars and emergency service vehicles are just a few of possible implementations.

The DVR Tral 1-22T model is specially designed to operate in heavy operation conditions (T stands for “transportation”).

DVR Tral 1-22 generates a standard data stream; therefore remote viewing of real-time and archived video can be done using any PC, or the non-PC based video terminal Tral Vision.
