Powered by XOS
The XOS operating system was designed and developed by SAY Security Group USA in 2005.  It was written specifically to meet the needs and solve some of the problems of the Security Industry and the DVR community.  Past DVR systems have run on Windows 98, 2000 or XP.  The XOS was written to improve security, speed and reliability of PC Based surveillance systems.   PC DVR systems are vulnerable to viruses, hacking attacks, and other Windows slow downs.  These security threats have caused many in the industry to gravitate towards Linux-based Embedded DVR’s.  These are widely accepted as being virus free and maintenance free for the user and installer.  However, PC Based DVR’s are undisputedly easier to use, capable of storing more video, and are easier to integrate with POS and card access systems.  The XOS offers the best of both worlds; the stability, quality, and security of an Embedded DVR while giving the user the ease of use, high record resolution and long term storage options of a PC DVR.

Technical Description
XOS runs on Microsoft’s stable XP kernel.  The XOS install footprint is 80% smaller than the full version of XP Pro. XOS can also be sealed, protecting the DVR from malicious or unintentional damage by the user or an online threat.  Each time the DVR is started, it returns to its default operating state that can only be changed from the DVR by an authorized operator.  Unauthorized changes are discharged when the DVR is restarted.
SAY Security uses the XOS on its Rackmount, Compact and Lite series DVR’s.  The Rackmount and Compact DVR’s utilize solid-sate flash memory to run the XOS.  This gives the DVR’s the speed and stability of embedded Linux.  No moving parts contribute to the long life expectancy of the DVR.  Video storage is still held on standard high speed SATA Hard Drives.  The XOS is built on two stable Intel Based motherboards.
The XOS is not a substitute for low-end Embedded DVR systems.  It was designed to give the same speed and stability to PC DVR systems that come inherently with embedded systems.  The benefits are outlined as follows:
