Video Surveillance Systems use two main concepts for video storage, namely, central video recording systems and Edge recording systems. These two concepts complement each other, with Edge storage being used as a backup to the central storage server systems. Below is a look at some of the scenarios where Edge recording comes in handy.

1.    Camera connection is downNYC Edge Recording Systems - Installations In All Boroughs

There are various instances where the network connection to one or more security cameras is lost. This is usually caused by faults on the network infrastructure, which connects the cameras to the video recording server. When this happens, the cameras are unable to send the recorded video to the central server for storage. With edge recording,  the video can be stored onboard the cameras that have lost connection, and the data retrieved once the connection has been re-established. 

2.    Recording server malfunction

Edge recording offers an ideal and low-cost backup solution when a system or hardware malfunction knocks out the central recording server. The video is stored onboard and retrieved automatically once the fault is fixed and the central server is online.

3.    System maintenance

Routine maintenance requires users to turn off their video recording equipment for a period of time. During this downtime, the security cameras have nowhere to send the recorded video. Under such circumstances, a failover server can be used for video storage. However, setting up parallel servers is quite expensive, making Edge recording systems a favorable alternative.  The video is temporarily stored onboard the cameras, for the entire length that the recording servers are turned off. Once system maintenance is complete and the servers turned back on, the system will retrieve all recordings from the individual cameras.

4.    Mobile surveillance applications

Video surveillance applications that involve mounting the security cameras on moving vehicles can prove difficult to design and implement. Usually, the nature of such applications cannot allow for a direct network link to a centralized video storage system. Therefore, the video has to be recorded onboard the cameras until such a time that the vehicles return to base to allow for the video to be transferred to the central server storage.
