Multicasting vs. Multistreaming in IP Video Surveillance Deployments

One of the advantages of IP video vs. analog CCTV is the distribution flexibility of IP networks. With IP networks, video can easily be routed anywhere on the network, to one or more endpoints as desired. In turn, users have the potential to over-utilize network bandwidth and compromise the overall performance of the video management system solution.

Drawbacks of Multicasting 
Some consider IP multicasting as the solution to minimizing IP streaming bandwidth, when in actuality the advantages of multicasting are limited to specific scenarios. With multicasting, bandwidth savings only occur when multiple subscribers view the same live video stream. Several drawbacks to multicasting should be considered including:

  • UDP video streaming – UDP does not guarantee every packet gets delivered and it exposes the video stream to any unreliability of the underlying network, resulting in poor video quality due to lost or duplicate packets.
  • Higher complexity – multicasting implementation requires special equipment and knowledge beyond fundamental IP network configuration.
  • Variable bandwidth savings – the amount of bandwidth savings can fluctuate depending how many people request the same content. Multicasting only delivers benefits when the same live camera stream is being viewed by multiple people.

Multicasting

One advantage of multicasting is that only one stream of video from the camera is required to support many viewers.  exacqVision provides this same benefit without the complex configuration. exacqVision is designed to efficiently support many clients viewing live video using only a single video stream from the camera.

exacqVision Saves Significant Bandwidth with Multistreaming
exacqVision is able to deliver significant bandwidth savings through the support of intelligent multistreaming, instead of multicasting. exacqVision will automatically deliver the full resolution stream or low resolution stream based on the viewing need of each client requesting video. Users can override the automatic choice and manually select high or low resolution streams for viewing as needed.

Migrating From Analog to IP Video

Is your legacy analog video security system reaching the end of its life? Some companies have been hesitant to make the leap to IP-based video, while other companies continue to look for the most cost-effective solutions to utilize existing infrastructures and maximize their surveillance investment while also adding new IP cameras. Meanwhile, the benefits of switching analog cameras and aging DVR systems to IP-based surveillance systems and network video recorders (NVRs) continue to grow.

Leverage Existing Infrastructure and Add IP Technology
Video surveillance technology is rapidly improving. Hybrid NVRs allow users to connect existing analog cameras and encoders as well as the latest IP cameras to the same server. This approach maximizes a company’s initial security investment while providing the flexibility to upgrade over time. As a result, end users can add IP cameras to their system in order to reap the benefits of high definition resolution, panoramic video, camera-based video analytics and more.

So What Makes IP Video Better?

Why IP Video
Why IP Surveillance Video?

IP-based video provides radical improvements over analog video. IP video is transferred over a computer network cable instead of a coaxial cable, which provides options for more flexible and higher resolution video. IP video improvements include video resolution, event analytics and situational awareness.

  • Larger, flexible viewing areas – Standard definition analog cameras have a maximum resolution of 704 pixels wide by 576 pixels tall—or .4 megapixels of resolution. Most IP cameras are between 1-5 megapixels, and some are up to 20 megapixels. In many cases, one IP camera can cover the same area as four or more analog cameras. Flexible resolutions are available to optimize the viewing area of the user’s environment. IP cameras can define their own aspect ratios to meet specific needs.
  • Panoramic video – There are many IP cameras on the market today that use multiple lenses and imagers to create 180 to 360 degree fields of view. Other cameras utilize panoramic or “fisheye” lenses to achieve these parameters on a single lens. A good VMS will allow you to bring this powerful video into your server with a single stream and to even zoom in and move around within the image for greater detail.
  • Improved camera analytics – Many IP cameras make use of video analytics that are built into the software or firmware utilized by the camera. These “smart” cameras can detect when a person or object crosses a line, detect objects left behind or removed from a field of view and more. These events are sent from the camera to the server so the user can be quickly notified. This approach does not require as much processing power from the server while freeing it up for other video management system tasks
  • Manage video from anywhere – IP-based video gives users the opportunity to easily view live and recorded video from any location through a PC, web browser or mobile device.

How to Configure Your System with Analog and IP
You know the cameras your company has in place or want to add to your system and need to know what server best suits your needs. An online configuration tool can help you calculate the approximate storage and bandwidth necessary for a security system. Users can simply enter the number of analog and IP cameras, the number of streams, compression, desired video resolutions and other features to find the best NVR that fits their needs.
