Edge recording was for many years considered a novelty video storage solution, but could not be deployed as the primary storage system for any serious video surveillance application. Nevertheless, various security camera manufacturers ensured that all their cameras came with SD card slots. The concept of Recording at the Edge could only be applied when setting up backup storage to prevent the likelihood of losing video data if the connection between the cameras and central recording server is lost, or the central server goes offline due to system malfunction or maintenance.
What does Edge Recording Cost?
Initially, the adoption of Edge recording as a primary video storage solution was slow due to a variety of reasons, namely, the cost of related technologies and limited storage capacities. Over the years, flash memory, which is the main technology behind on-board storage, has matured and experienced a considerable reduction in price. The favorable price points, increased storage capacities and enhanced reliability allow this technology to compete in the marketplace with other storage technologies.
Ideal Surveillance Applications for Edge Storage
1. Redundancy for Large Surveillance Applications
Edge storage is one of the best ways of creating a redundant video recording solution in large surveillance applications. This is opposed to setting up parallel recording servers to take over if the standard servers malfunction. Besides, it is possible for network malfunctions to affect the failover recording servers and thus, lead to loss of video. Edge recording doesn't need to send video to a centralized server for storage. As such, any time the cameras lose their connection to the video storage server, they can record to onboard storage and sync the footage when the connection resumes.
2. Failover Recording for Smaller CCTV Installations
Setting up failover recording servers for small-scale CCTV installations could prove expensive, considering that the servers will likely be idle most of the time. As such, edge storage is an appropriate substitute, with regard to the functionality and cost effectiveness. The security cameras would only record onto the onboard memory if the central recording server goes offline.
