TL/DR: Edge storage stores video data directly on the camera or nearby devices, reducing the need for central storage and allowing faster access to footage.
Edge storage is a method of storing video data directly on the camera or on a nearby device within the same network, rather than on a central server or cloud. This approach enables the camera to record and store data independently, often using SD cards, solid-state drives, or other local storage devices within or connected to the camera. Edge storage allows continuous or event-triggered recording, helping ensure data is available even if the network connection to central storage fails. In many systems, edge storage is used in combination with central storage to provide backup and enhance the overall reliability of video surveillance.
Edge Storage stores video directly on the camera or a local device within the network, ensuring data availability even if network connectivity is lost. It reduces bandwidth usage by keeping data closer to the source and can be used for immediate access or as a backup. However, storage capacity is limited to the device’s hardware, and it may lack scalability for larger surveillance setups.
Cloud Storage stores video on remote servers managed by a cloud provider, offering high scalability and remote access from any internet-enabled device. It provides more storage flexibility and enhanced security with centralized management, but it relies on constant network connectivity and may require higher bandwidth to upload large video files.
Edge storage works by recording and saving video footage directly onto storage media within the camera or a nearby network device, such as an SD card, SSD, or hard drive. When a camera captures video, it writes the data directly to its internal or attached storage without relying on a central server or cloud connection.
This method enables cameras to operate and store footage independently, preserving data even if there’s a network disruption. The footage stored locally can be accessed either through the camera’s interface or downloaded to another device when needed. Edge storage is often used alongside central storage solutions to provide a reliable backup in case of connectivity issues.
