Optimizing storage efficiency and duration is a frequent cctv / video surveillance topic.

I put together a survey of DVR / NVR storage optimization measures.

I think most people who frequent these forums know those techniques well, but for those who don't, it might help.

Below is a summary of the 8 topics I review:

# Basic Motion Analytics
# Advanced Video Analytics
# Motion Exclusion Zones
# Data Aging
# Recording Schedule
# CODEC Selection
# Dual Streaming
# Storage Clusters

What others would you add or change?
