Edge Storage

Mini-SD, Micro-SD Embedded Storage Slots

Axis Communications IP cameras in coordination with Milestone Systems XProtect Corporate can utilize SD cards inside of the camera itself to store video locally until a provisioned event pulls the video to the Milestone server. This technology is also available with Axis Encoders to utilize the same technology when migrating away from analog camera systems. There are two primary use cases for this technology; one is to alleviate network load and the other is for fail over. Axis SD Card

In the first scenario, the Axis IP Camera is generally responsible for recording on motion and the Milestone server is provisioned to pull streams recorded on the camera in regular intervals or at set times. This alleviates the load of all video streaming across the network and having the Milestone XProtect software decide what video to keep. In this instance, the camera itself generally decides when motion is present and the network only has to transport video of motion. This type of setup is very common in our hosted/cloud IP Video Surveillance solution and/or systems with distributed campuses.

In the second scenario, the embedded storage in the SD card is provisioned to store video only when there is a network outage. This provides a very efficient level of resiliency at the camera directly. When connection is restored between the IP camera and the Milestone server, the video that was stored on the SD card is seamlessly pulled back to the Milestone recording server for playback. The video is generally marked in the Milestone timeline with a different color to indicate video that was retrieved from the SD card. Other than the color marking for statistical purposes, the video is managed and archived exactly as all other video feeds.
