Many of the embedded units use some version of Linux as an O/S.
Windoze isn't stable enough for security applications, especially when
the system is connected to a network with outside connections.

As a side note, the video industry is changing, and the traditional
DVR may become obsolete relatively soon.  There's a push to store
video at the device or "on the edge" of the network.  Megapixel
cameras or traditional cameras with Ethernet encoders at the camera
will enable recording devices to be hung anywhere on the network.
Client/ Server configurations with RAID storage enable you to secure
your video on super-reliable servers and still access it with
relatively simple, inexpensive windows-based clients.  Once encoded,
video can be managed digitally or decoded and managed using tradtional
analog processing equipment.

Most of the major CCTV companies have bought into this concept.  We've
used the Verint products, some AD, and Bosch's VIDOS recently.  Given
enough bandwidth, the technology is nice.  Bandwidth and network
integrity seem to be major issues, although storing video at the
camera end cures some of this.
