In the present-day context, security has emerged as a matter of utmost significance, particularly for individuals and businesses striving to safeguard their assets and people. While conventional video surveillance systems have long been relied upon, they come with inherent limitations.
The VSaaS service is highly scalable in terms of the amount of stored video, the number of observation points, and the number of system users. The most significant barrier to expanding VSaaS services in the world is the insufficient bandwidth of communication channels outside the local network. Compare the data streams generated by the cameras with average subscriber connection speeds. On the one hand, even when using modern compression algorithms such as H.264, standard definition cameras (0.4 megapixels) form a data stream from 0.5 to 4 Mbit / s, and high-definition cameras (13 megapixels) from 1 to 10 Mbit / s for good viewing conditions and up to 50 Mbit / s for bad. For systems with a large number of cameras, the cost of transmitting, storing and analyzing data becomes critical. On the other hand, the average speed of the outgoing channel is 4 Mbps in the world. When using asymmetric access technologies (for example, LTE, 4G, ADSL), the outgoing channel from the subscriber to the VSaaS application is 410 times smaller than the incoming. Thus, the VSaaS service does not allow remote viewing and recording of video from a larger number of cameras, especially high-resolution cameras.
