Understand how edge storage works in video monitoring systems, including failover recording, low-bandwidth applications, storage cards, and VMS integration.

Edge Storage (Edge Storage) – also known as local recording – is an economical and efficient recording solution designed primarily for the implementation of a Video Monitoring Project in locations with limited or nonexistent network bandwidth.
The use of edge storage can increase the reliability of a system by ensuring continuous recording and the availability of complete videos for use as evidence in the event of network or server failures. This application is considered a form of contingency recording (failover).

Edge Storage plays a crucial role in mobile and remote applications, such as public transportation systems (trains and buses) and agricultural operations in distant locations, where the Network Infrastructure may be unstable or inaccessible.
“This technology enables local capture of high-resolution data, complementing low-resolution data transmission in bandwidth-constrained environments.”
Main Applications of Edge Storage
Edge storage has two general applications in Video Monitoring Systems:
- It is extremely useful in mission-critical locations such as airports or large transit stations. In these environments, reliability and continuous data availability are of utmost importance;
- It enables data storage directly on the source device, allowing applications in environments with unstable network coverage.
Recording Redundancy
Edge storage, in this context, can function as an essential part of a strategic contingency plan. It serves as an additional layer of redundancy for video recording, complementing centralized storage.
“Security cameras that monitor entrances and exits can employ edge storage to ensure continuous video recording, even in the event of network failures. This ensures that no critical data is lost and that operations can continue without interruption.”
Edge storage has the ability to record videos locally whenever the centralized system is unavailable, or it can operate in parallel with the Video Management Software (VMS), recording videos continuously.
One of the main benefits of edge storage is its ability to enable “failover” recording. This means that during network failures or system maintenance, images can be temporarily stored on the camera’s SD card.
When the network connection is restored and the system returns to normal operation, the central VMS can automatically retrieve the missing video clips from the camera and merge them seamlessly with the existing video recordings.
This increases reliability and protects system operation, ensuring that no critical data is lost.
Recording on secondary storage during failure:
- During normal operations, the camera transmits video to the VMS for storage.
- In the event of a network failure, video clips are temporarily stored on the camera’s SD card.
- When the network is restored, the VMS retrieves the missing video clips and merges them into the recording.
Edge storage for redundancy is compatible with most NAS (Network Attached Storage) products.
Low-Bandwidth Environments
Edge storage is essential for improving video analytics in systems with limited bandwidth. In these systems, high-quality video transmission may be unfeasible.
Together with Edge Storage, the implementation of advanced video compression algorithms can significantly reduce bandwidth and storage requirements while keeping all relevant forensic information intact.
One example of this application is installations on board a train. In this scenario, edge storage allows continuous video recording during vehicle operation, since the data is stored locally on the device, eliminating dependence on a constant network connection.
When the vehicle arrives at a station and a network connection is available, the recordings can be transferred to the central system.
Storage Cards for Video Monitoring
The storage cards used for video monitoring are predominantly based on Secure Digital (SD) technology, which includes variants such as SDHC (Secure Digital High Capacity) and SDXC (Secure Digital eXtended Capacity).
These flash memory devices are designed to provide high storage capacity for portable devices such as video cameras and smartphones.
In our Online Store, we offer SD cards specifically designed for video monitoring applications.
These cards are optimized to ensure superior performance in such applications. As they are industrial-grade cards, they are impact-resistant and capable of operating efficiently in extreme environments and temperatures.
Cameras with Edge Storage
Cameras with edge storage (Edge Storage) are an innovative solution for video monitoring. They have the ability to store videos directly in the camera through an SD card, increasing system reliability and enabling high-performance system applications in remote regions.
In our Online Store, we offer a wide variety of high-quality cameras. These cameras are designed to deliver superior performance and reliability in video monitoring applications.
Video Management Software
Video Management Software (VMS) platforms are essential components in video monitoring systems, providing a centralized platform for managing and analyzing video feeds from multiple cameras.
When integrated with edge storage technology, they can significantly increase the robustness and flexibility of these systems.
