Edge recording is a relatively new technology, which allows users to deploy surveillance architecture that are significantly different from the centralized storage solutions. Edge recording IP camera systems can store captured video onto onboard media such as SD cards or other plugged in devices at the edge of the video surveillance system. This is in contrast to the traditional central storage architecture, whereby, the security cameras have to send the recorded video to centralized video servers for storage.
The Advantages of Centralized Video Recording Systems
- Scalability: When deploying video surveillance applications with central storage servers, users have a freehand to scale or expand their video storage capacity to suit their requirements and budget.
- Customization: Centralized video storage systems allow users to tailor their surveillance applications to match the performance of their surveillance system.
- Redundancy: The central video recording systems can work with storage redundancy systems to ensure that video is not lost if the main recording system malfunctions.
The Disadvantages of Centralized Video Recording Systems
- Dropped Connections: If the connection to the security cameras is lost, it won’t be possible to transfer the recorded video to the central video storage servers
- Storage Server Malfunction: If the central storage server goes down as a result of a hardware/system failure or if the server is taken down for maintenance, video storage is interrupted .
The Significance of Edge Recording IP Camera Systems
Edge recording has in the past few years gained some footing in surveillance applications. The reason for this development is the gradual increase in storage capacities, favorable price points and higher level of reliability that has been occasioned by the maturity of onboard storage technologies such as flash memory. As such, most security camera manufacturers have started incorporating onboard storage on their cameras. Edge recording IP camera systems have three main advantages, namely:
- Flexibility: Onboard storage enables users to design more flexible surveillance applications.
- Low Bandwidth Usage: Edge recording lifts the burden of having individual cameras send continuous streams of data to the central storage servers. As such, very little bandwidth is required.
- Mobile Surveillance Applications: Recording at the Edge makes it possible to deploy surveillance cameras on moving vehicles.
