Dynamic resource allocation - The process used by Phoenix RSM to find and use storage resources that
may be available across multiple storage devices.
E
Encoder - A device which takes the video signal created by an analog camera and converts it to a digital
format as created by newer digital cameras. It is most often seen when using older cameras in newer digital
systems.
F
Forensics - The process of reviewing recorded surveillance video to determine what happened in the past.
Phoenix RSM is a forensic video system.
Frames per second (FPS) - Frames per second, is an expression of frame rate. Surveillance cameras
record anywhere from less than 1 FPS to greater than 30 FPS. For the best chance of conviction based on
video evidence in a court of law, chain of custody procedures require 30 FPS.The higher the frame rate, the
smoother the video looks.

cameras.
Header - In data storage, a header is an area on media where the parameters assigned during preparation
of the media are stored. The information contained in the header includes access control lists (ACL),
storage pool information, media size, type, etc.

Information Lifecycle Management (ILM) - The policies, processes, practices, and tools used to align
the business value of information with the most appropriate and cost-effective IT infrastructure from the time
information is conceived through its final disposition. When ILM is video aware, it is called Video Lifecycle
Management (VLM).
Information Repository - The Information Repository is where data is stored. Since a Vault is a storage
device used to store files, the Information Repository is made up of all the storage devices, clients and
Vaults on your network.
Ingesting - The process of using Phoenix RSM clients to archive or move data, including metadata, from a
networked computer into the Information Repository. Capturing video from RTSP enabled IP cameras is a
type of ingesting.
