Securtex International is shipping a line of Linux-powered DVRs (digital video recorders) for security and surveillance applications.

In addition to its “NAVS-E” products based on embedded Linux, Securtex offers a line of Windows-based “NAVS” products capable of integrating with cash registers, as shown in the photo at right.

Securtex says that both its NAVS and NAVS-E devices support “Pentaplex” operation, meaning that remote Windows-based client software can be used to simultaneously monitor, record, play-back, backup, and configure the devices, within the limitations of available network bandwidth.

Securtex LiveViewer Windows software can aggregate the output from several E-NAVS devices, displaying up to 64 thumbnails
