We think the quick adoption of H.264 will see a rise in megapixel and HDTV cameras which will be able to meet the market’s demands while maintaining current levels of bandwidth and storage use.
Axis has already released their first HDTV camera with the Q1755 and the results are impressive.
Latency is the time it takes to encode, send, decode and display the video to the operator.
H.264 offers a low latency (in milliseconds) which is a necessity for surveillance monitoring.
The bitrate is the total number of bits traveling between 2 devices at a given point.
Using H.264 allows you to make cost savings when designing a new surveillance system.
Advanced motion compensation, intra-prediction encoding, and an in-loop de-blocking filter which smoothes out the images.
We’ll talk more about how H.264 works later in this article.
We hear bold statements about low bandwidth usage, reduced storage requirements, higher resolution monitoring and better quality images and it all sounds too good to be true… Demands from the security industry constantly push for higher resolution monitoring and faster frame rates without any compromise on image quality.
With conventional compression formats this just isn’t possible but with the introduction of H.264 we can see many benefits which can improve the quality of security surveillance applications.
Without low latency the images would not appear in real-time to control room operators and cameras with pan-tilt-zoom (PTZ) control would be difficult to operate as the images would not update in time with the controls. When you use H.264 to view a conventional VGA video stream you will make great savings in terms of bandwidth and storage requirements as we have already mentioned but what it also gives us is the ability to deliver higher resolution video and better image quality at the same bitrates are we are using for conventional VGA cameras.
