The Bosch Security System blog recently as touting bitrates as a metric that
DVR manufacturers should publish alongside their frame rates and image resolution. I totally agree that missing information is one way to fool a buyer into thinking they're comparing like systems when they are not.
I commented on the post but, fair enough, they seem not to want to publish a comment from a competitor about the advantages of their systems. Or maybe they're too busy to approve the comment. Whatevs.
Here's what I said which no-one can object to me posting here on the Airship blog:
A system with a hard-and-fast bitrate is not going to work for many users. Users and Integrators want to be able to decide how much data traffic to put on their network, how much data they want to store in a 24-hour period. A good system will allow users to set a bitrate based on their needs. Airship DVR systems go further by offering a variable bitrate which responds to recording conditions to capture the best images with the most advantageous bitrate.
Why? Recording a store room that's usually empty is very different from recording a busy lobby or train station where there is constant motion in the entire image area. Airship has a very default high ceiling rate that can be adjusted by the user. This ceiling is almost never reached but is available should recording conditions require it. At the other end of the variable spectrum is a low rate for periods of no activity.
Simply put: The system will adjust to the conditions and capture the best images at the right bitrate. At the same time, it gives the network administrator peace of mind since Airship systems will never exceed the bandwidth limit set by the network administrator.
