The main storage modes of surveillance camera

The advent of webcams has changed the situation of storage solutions in the security industry. As monitoring systems move to web-based systems, the choice of records and storage is no longer clear. Today's storage solutions include network hard drive VCR NVR, edge storage and cloud storage solutions. System integrators should first differentiate the advantages and disadvantages of each solution to help customers choose the best record and storage solution to meet their requirements.

Network hard disk video recorder NVR

The network hard drive video NVR machine can be PC based or independent. Storage technology can be freely chosen from different storage systems supported by Microsoft Windows or Linux. In this way, system integrators or end users can choose the storage system that best suits their needs and budgets. The VCRS can be extended and upgraded to meet the storage requirements, and the performance of the storage system can be customized according to the actual needs of the monitoring system. Finally, storage redundancy techniques can be used to ensure that the storage system is always online and that the recorded data is not lost. Organizations with IT skills, adequate resources and network infrastructure can best deploy VCRS. Regularly purchasing network equipment and establishing good relationships with IT vendors, organizations can share resources and expertise with customer resources.

In many cases, video will not be able to record. At the front-end, for example, video cannot be recorded if the camera connection fails. Video cannot be recorded if the back end of the recording or storage solution fails, possibly due to a system failure or routine maintenance. The failover recording solution prevents this problem.

Edge of the storage

The edge is stored at the edge of Ethernet for recording, rather than sending data across the entire network to a centralized network hard drive video recorder. In essence, the concept refers to the ability to store and transmit between cameras in a decentralized manner. It works by recording video directly to a storage device, such as an SD/SDHC card that inserted into the camera, a built-in flash memory, or a small hard drive. Edge storage brings an alternative to the monitoring architecture. By supporting high-quality low-bandwidth monitoring of local recording, users can optimize bandwidth limitations and obtain high-quality video from event video for detailed investigation.

The three main advantages of edge storage are decentralized storage, redundancy and low bandwidth. Decentralized storage saves money by not recording video's live servers, network drives, or computers. If the camera is disconnected from the central server, it provides failover recording.

Some people believe that edge storage is unreliable because cameras fail or are stolen. If all the video is stored in the camera, it must mean that all the video will be lost. In addition, video recording capacity in edge storage has limits, such as 7 days or less, depending on SD card capacity and recording Settings. Therefore, the scheme may not be entirely suitable for applications requiring video storage up to 30 days. In addition, end users often don't know that the SD card has a life limit, and video will not be able to record if it reaches the deadline.  

Cloud storage

Cloud storage is often marketed as video monitoring as a service (VSaaS). This service enables end users to eliminate hardware investments because video and audio are stored and recorded in the cloud. VSaaS is a purchasing service that pays periodic fees to video service providers. On the other hand, investment in cameras and demand for Internet traffic are down. Maintenance and storage are outsourced to service providers. According to a new research report by TechNavio, the market for VSaaS has grown to $1.6 billion in 2016, driven by video analysis software from suppliers. The adoption of video analysis software will increase the value proposition of VSaaS. Our production JH0164G Outdoor Security Camera support 30-days Free Cloud Storage.

Although low initial investment, low maintenance costs can attract many homes and smaller companies, but many security the personage inside course of study thinks, cloud storage is more suitable for smaller than high security applications. VSaaS is more popular in residential and small business customers, because it can provide remote management flexibility, but the data security and bandwidth challenge is still the main problem for the large group. In the organization, safety is often a key task.
