Video surveillance is a vital tool for protecting people and property around the clock. The increasing availability and, thus, lower cost of higher-quality cameras makes improving the effectiveness of video more affordable. However, a new issue now holds back users increased storage requirements. In a normal retail environment, it is common for video storage costs to exceed 50% of the entire surveillance system cost. This places an incredible financial burden on retailers, especially during these tough economic times. In response, many retailers are turning to ?record-on-motion? devices that have the potential to save storage, but can leave costly gaps in visibility.
