Thefts and robberies occur regularly on Australia’s over 7 million kilometers rail network. Surveillance by the police is too manpower-intensive and costly. The authorities opted for a DVR system with IP cameras to monitor the wagons. The AIoT devices must be reliable and need fast memory to receive interference-free videos and ensure their analysis without loss of speed. Innodisk’s easy-to-integrate DRAM solutions provide the necessary quality and secure data management. They have a high storage capacity to store the amount of data from several connected IP cameras. In the process, each camera delivers high-resolution data material that must be processed at high and stable write speeds to avoid image loss. The components used must be robust, resistant, and compact, as they are exposed to constant vibrations and voltages. DRAMs with a capacity of 2 GB and a DDR3 speed of 1333MT/s in the compact SODIMM form factor are used. The Toshiba TLC 3D NAND in industrial quality with high-quality NAND flash technology from Innodisk, which is also used, has a storage capacity of 4TB. It is firmware-optimized for surveillance applications with high and stable write speeds. All modules have a small form factor and are designed for the harsh conditions on board vehicles.
