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.
