In this role, it operates as a <b>failover<\/b> recording layer.<\/p>\n\n\n<p>[elementor-template id=&#8221;24446&#8243;]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Edge storage is especially important in mobile and remote applications such as public transportation systems, trains, buses, and agricultural operations where <b>network infrastructure<\/b> may be unstable or unavailable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>&#8220;This technology enables high-resolution data to be captured locally while lower-resolution streams are transmitted across bandwidth-constrained networks.&#8221;<\/i><\/p>\n\n\n\n\n<h2 class=\"wp-block-heading\">Main Edge Storage Applications<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Edge storage has two main applications in <a href=\"\/blog\/video-monitoramento-ip\/\" target=\"_blank\" rel=\"noopener\">video surveillance systems<\/a>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It is particularly useful in mission-critical environments such as airports and major transportation hubs, where continuous data availability is essential;<\/li>\n\n\n\n<li>It allows data to be stored directly on the source device, enabling operation in environments with unstable network coverage.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Recording Redundancy<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In this context, edge storage can serve as an essential part of a contingency strategy.&nbsp;It provides an additional recording layer that complements centralized storage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>&#8220;Security cameras monitoring entrances and exits can use edge storage to maintain continuous recording even during network failures, reducing the risk of losing critical video evidence.&#8221;<\/i><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Edge storage can record video locally whenever the centralized system is unavailable, or it can operate in parallel with the <b>Video Management System (VMS)<\/b> for continuous recording.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of its main benefits is <i>failover<\/i> recording. During network outages or maintenance, video can be temporarily stored on the camera\u2019s SD card.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When connectivity is restored and the system returns to normal operation, the central VMS can automatically retrieve missing clips from the camera and merge them into the existing recording timeline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This improves resilience and helps prevent loss of critical video data.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/a3aengenharia.com.br\/wp-content\/uploads\/2024\/05\/edge-storage-failover-1024x396.png\" alt=\"Diagrama ilustrando um sistema de monitoramento de v\u00eddeo com armazenamento em borda.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Recording to secondary storage during a failure:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><i>During normal operation, the camera streams video to the VMS for storage.<\/i><\/li>\n\n\n\n<li><i>If the network fails, video clips are temporarily stored on the camera\u2019s SD card.<\/i><\/li>\n\n\n\n<li><i>When the network returns, the VMS retrieves the missing clips and merges them into the recording.<\/i><\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Edge-storage redundancy can also be integrated with NAS (Network Attached Storage) architectures, depending on camera and VMS compatibility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Low-Bandwidth Environments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Edge storage is valuable in systems with limited bandwidth, where continuous transmission of high-quality video may be impractical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Combined with <i>edge storage<\/i>, advanced <strong>video compression<\/strong> can significantly reduce bandwidth and storage requirements while preserving relevant forensic information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A typical example is onboard train surveillance. Edge storage enables continuous recording while the vehicle is moving because video is stored locally, eliminating dependence on a constant network connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the vehicle reaches a station and network connectivity becomes available, recordings can be transferred to the central system.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/a3aengenharia.com.br\/wp-content\/uploads\/2024\/05\/armazenamento-em-borda-a-bordo-1024x576.jpg\" alt=\"\"\/><\/figure>\n\n\n\n\n<h2 class=\"wp-block-heading\">Storage Cards for Video Surveillance<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Storage cards used in video surveillance are predominantly based on <i>Secure Digital<\/i> (SD) technology, including variants such as SDHC (<i>Secure Digital High Capacity<\/i>) and SDXC (<i>Secure Digital eXtended Capacity<\/i>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These flash-memory devices provide local storage capacity for devices such as video cameras and other embedded equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>In our <a href=\"\/loja\/\" target=\"_blank\" rel=\"noopener\">Online Store<\/a>, we provide SD cards designed specifically for video surveillance applications.<\/i><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These cards are optimized for surveillance workloads.
