Small Diskless Servers

This article describes the concept and need for small diskless servers. This concept is quite applicable to the building of a VMS with enterprise storage or the infrastructure of a PSIM.

 

Transcoding for Security Video

Technology leaps in video security are often fueled by developments adopted from large dollar markets like entertainment. The use of transcoding and format down sampling in the DynaView SOC Video Management System are good examples of this approach.  This article offers a good discussion of the power and value of these techniques.

The Evolution of Transcoding

For live video streams used in security and surveillance applications on demand transcoding and format conversion offer substantial reductions in wide area network utilization while requiring practical levels of server and router power.

Help From Afar

The ability to administer a network video system from a remote location is a great time and cost saver. Windows remote desktop is commonly used for this purpose but does not work well with IP video environments. There are several available solutions that do work and an open source remote control package we highly recommend is UltraVNC.

UltraVNC consists of a server part installed on the machine(s) you wish to control remotely and a client part installed on your local machine. The machine(s) running UltraVNC server must be reachable by an IP address or Domain. Note that this IP address or domain could be temporary as long as it does not change during the remote control session. Complete installation instructions are provided for UltraVNC.

By default UltraVNC requires ports 5800 and 5900 to be open in your firewall. These ports may be changed if need be. You should not expect video viewed through UltraVNC to be of good quality – this package is meant for control and admnistration and will serve the purpose very well.
