Data mirroring for take away
|
Thanks to the excellent video compression of the Linux-based DiREX-Pro DVRs, data can easily be mirrored simultaneously to internal recording on USB data storage. The internal FIFO ring memory is herewith extendable up to 2 TBytes.
This solution offers many advantages compared with ordinary HDD racks:
- a USB interface provides a sturdy and easy 'Plug-and-Play' solution,
- with the user-activated data mirroring, original data are preserved in the device,
- the total memory can be extended with additional 2 TBytes (capacity extension mode),
- inexpensive USB memory sticks provide extremely robust data protection.
The day's agenda on a keyring
USB flash memory stick solution is especially suitable for shift work (cash desks, workshops, etc.) and transport applications such as public transport (taxi, buses, trams) and also freight traffic (courier services, transport of valuables, freight). At the start of the working day, the personal USB stick is connected to the integrated, fan-less recorder. Thereby video, audio or also GPS data (i.e. coordinates, direction and speed) will be simultaneously recorded onto the internal automotive HDD (with DiREX-Pro.A30) and the flash memory.
By means of an optionally available RS-232 alarm box, the employee can use a 'panic button' to set alarm marks for later data analysis. At the same time, the system can save appropriate status reports inside which are transmitted either immediately by 3G/GPRS channels, or later via an Access Point wirelessly to the central office.

Thus every staff member can take his 'daily routine' at the end of the working day and, when required, be able to analyze his personal video journal - independently of workplace or vehicle. 4GB sticks suffice for the complete documentation of an average working day, though the 8GB sticks already available are recommended for future contingencies.
Regardless of the subsequent handling of the data carrier, a backup copy of all data is preserved in the DVR and a WLAN connection during a stay in a garage, for instance, can be retrieved via a protected company network.
If size matters...
 The external USB memory is recognized by the DVR as an independent data disk drive and, thanks to FIFO ring memory (also like the internal HDD), can be set for continuous recording. In addition, the external USB data drive can be configured either in a mirroring mode, or as a pure memory extension of the internal HDD.
The Linux operating system allows management of up to 2 TBytes which, together with DiREX-Pro.120 (120GB version) DVR, provides an extremely long recording capacity. As the USB disk drives are not accessible via network, a mechanical protection of the data carrier would be enough to meet application-based and country-specific data protection regulations.
When required, all data can be brought instantaneously for checking where above the USB-2.0 interface a quick analysis can be carried out directly from a PC. The use of an external USB RAIDs makes even a redundant solution possible, moreover one which a quite unrivaled value for money.
