Surveillance-optimized microSD cards for surveillance edge

In surveillance architectures the video content can be stored locally in the camera (edge storage), at the server/cloud side, or a combination of the two locations. Deploying edge storage creates powerful benefits. For smaller installations where space and resources are limited, elminate the overhead and cost for a dedicated onsite NVR/DVR. For mission critical deployments, increase system reliability with a fail-safe storage at each camera, ensuring uninterrupted operations regardless of network availability. And in cases where bandwidth resources are limited, or real-time analysis is desired, a hybrid edge and cloud storage solution optimizes bandwidth usage and provides instant actionable analytics. Consider an example, where high resolution video is recorded locally, while a user can view a live video feed in low resolution. The camera can perform real-time analytics based on the local copy, and can indicate whether any immediate actions are required. In the background, only the low resolution feed and/or metadata is sent back to the cloud for further "big data" analysis.

Important factors to consider when it comes to edge storage


The endurance is an indicator of the overall useful life of the system, and needs to support the intended use case. In a 24x7 recording system, a high endurance solution is critical to enabling reliability over a long period of time. For example, to support 3 years of continuous recording, at 10 Mbps, you will need a solution that supports 154TBW over period.


Ensure that have you enough capacity for your surveillance needs. For example, to store ~24 hours (ring buffer) of HD video at 10Mbps, you will need at least 128GB of storage.

Smart features

One such feature is a health status monitor, which will allow you track the health of the storage and enable preventative maintenance before any unexpected failures.
