4K, 5K, 6K, 7K Surveillance Cameras – What’s the Difference?
With Avigilon’s release of the industry’s first 7K surveillance camera this past August, there has been a lot of talk about the difference between the new options they have been given – 4K, 5K, 6K, and 7K Surveillance Cameras – and the options they’ve been getting used to over the past five years as IP video has risen to dominance. People are asking:
Who needs Ultra HD video surveillance?
What is the difference between the different classifications? 4K / 5K / 6K / 7K? Ultra HD?
How do I determine what I need?
This post should help our clients and readers to answer those questions.
What is the difference between 4K, 5K, 6K, 7K Surveillance Cameras?
As the photo below illustrates, these “Ultra HD” models are no different than any other imager classification, in that they are all defined by the number of pixels captured, transmitted and stored. Avigilon’s new 7K flagship provides 7,360 pixels on the horizontal axis, and 4,128 pixels on the vertical axis. The device nomenclature of “7K” comes from that horizontal pixel figure, indicating 7,000 horizontal pixels.
We could use a different naming convention – one that the video security industry has definitely become comfortable with over the years, and say it’s a “30 megapixel overview” providing the ultimate in situational awareness. The 6K device has roughly 6,000 pixels along the horizontal axis, but could just as easily be called “24 megapixel”. The 5K could also be called a 16MP unit, with pixel dimensions of 4,944 x 3,280, and the 4K is an 8MP camera at 3,840 x 2,160.
Who needs 7K video surveillance?
The basic idea behind these massive imagers is to gain an overview of a large scene (also known as “situational awareness”) while other camera positions focus on smaller areas.
Avigilon Pro Series devices like these are at home in a variety of settings, but Avigilon specifically points out that they are “ideal for stadiums, critical infrastructure, transportation and similar applications.”
Of course, not every location requires the power of 7K video surveillance. As systems integrators, PSX looks at at each unique setting individually and determines the best fit for that particular site and its circumstances.
How do I determine what type of video surveillance I require?
The best way to determine what type of video surveillance best suits your location is to request a needs assessment. PSX representatives will listen to your needs and visit your site to make a recommendation on the best fit for you.
