2.0 SI-2K Maintenance Tool (For SI-2K Recorders Only)
The SI-2K contains a compact flash memory card that appears as the “C:” drive when the
system is operating. The system boots and runs the SiliconDVR application from this drive.
The SI-2K Maintenance Tool is provided to quickly upgrade or restore the system’s flash drive
to a previous state, called a “snapshot”. This is an exact image of the full camera system –
SiliconDVR application, drivers and operating system. As such, any additions such as
touchscreen calibration or custom looks are overwritten by the process.
The SI-2K Maintenance Tool uses a USB Flash Drive (a “thumbdrive” or “pen drive”) which
has been loaded with a special version of the Linux operating system that allows the system to
boot independently of the internal flash drive and an application that allows snapshots to be
written.
The Snapshot files are included with the Maintenance Tool in order to restore or upgrade the SI-
2K.
