An Overview of Bandwidth Shaping
Understanding Bandwidth and the Internet
The term "bandwidth" is one which many consumers casually toss around without really understanding the technical aspect. Generally, consumers are aware that more bandwidth costs more as it relates to an ISP (internet service provider), but many have only a vague idea of exactly what it is they're paying for. So what does it mean when we talk about using more or less bandwidth on the internet?
When we speak of bandwidth we're referring to the volume of information per unit of time that a transmission medium (like an internet connection) can handle, usually measured in bytes per second. If your internet connection speed has been rated at 60 MBs, that means you can transfer 60 million bytes of data per second (a byte is 8 bits of data.) Large sets of data, such as video files, move much more quickly with large bandwidth and slow down considerably with low bandwidth. You might think of it as the difference in the volume of water delivered when comparing a fire hose to a garden hose.
An Overview of Bandwidth Shaping
Video Surveillance as a Service (VSaaS) is rapidly emerging as the preferred choice for new deployments or to replace legacy surveillance systems. VSaaS does away with local recording devices, servers, and software. The video is sent directly from the camera to the Cloud over a broadband connection for storage, navigation, and playback.
We've already mentioned that video files involve transferring large volumes of data, so it's obvious that conserving bandwidth is of the utmost importance to any cost-effective VSaaS system. ISPs set limits on the amount of bandwidth individual consumers can use. Bandwidth shaping is the technique which assigns network connections and establishes the bandwidth usage amounts best suited for different types of internet applications.
The process is also known as bandwidth allocation, bandwidth allocation tool, bandwidth management, and traffic shaping. All of them refer to the allocation of resources based on demand, for example using low bandwidth to send an email or high bandwidth to stream a video. Bandwidth shaping allows ISPs to direct resources in a manner which ensures reliable content distribution.
To go back to our prior analogy, bandwidth shaping ensures that you don't show up at the fire with a garden hose. In this age of ever-increasing bandwidth demand brought about by mobile phones, the Internet of Things (IoT), and the general trend toward digital transformation, bandwidth shaping plays a crucial role. The technique can also be used to manage bandwidth from the user's side to optimize cost-efficient performance for data-intensive applications such as video surveillance.
Bandwidth Shaping at VIAAS
VIAAS cameras can deliver high bandwidth video and uploads with a low bandwidth speed of just 30Kb/sec. After reading the bandwidth explanation above it's natural to ask just how this could be possible, as the idea seems to be so counter-intuitive. The answer is the use of bandwidth shaping technology at our end. VIAAS was among the first companies to deliver Cloud VSaaS beginning in 2008 and developed Bandwidth Shaping technology specific to VSaaS.
VIAAS cameras compress and encrypt video and image files for the most efficient use with a low bandwidth connection. The VIAAS camera's IntelEvent feature ensures that only significant action has been captured to avoid transferring enormous files containing hour upon hour with nothing happening.
Once captured and compressed, full videos are stored on MicroSD cards in a local buffer and only thumbnail images are transmitted immediately (a buffer can be thought of as a reservoir or data storage tank.) When bandwidth is available or the buffer fills, the full video is transmitted. Full videos are also available at any time on demand with our instant access feature. The "shaping" is this spreading out of data to upload evenly at a constant low bandwidth over time.
A Lost Connection Doesn't Mean Lost Surveillance
One of the prime benefits of bandwidth shaping is the ability to maintain surveillance even if the internet connection is lost. If a camera loses its connection to the internet, IntelEvent continues to record all significant events throughout the outage until the connection is restored. When the connection is restored, all files are recovered from the camera and no recorded events are lost.
