Dear Partner,

Please read the below article by John Honovich. We shall discuss your input after this section.

*******************Start of article**************

The word 'resolution' should be banned in surveillance. What all IP manufacturers mean when they say 'resolution' is 'pixel count.' We should be clear and precise, calling it what is - pixel count - to avoid confusion and making important mistakes.

Two Meanings

Traditionally, resolution meant the ability to resolve, or see, details. This focused on the user and the ability of the device to deliver meaningful visible benefits.

Now, resolution means the number of physical pixels that a sensor has - 1 million pixels 'resolution', 3 million pixels 'resolution', 10 million pixels 'resolution'.

What's Missing

Pixel count is only one element in a camera's capability to deliver visible details. Other critical ones include lenses, compression, frame rate, low light and WDR performance - some of which actually can be worse with more pixels. As such, resolution as 'pixel count' ignores critical elements in delivering real 'resolution'.

Height in Basketball

Pixels are like height in basketball. If you are too short or have too few pixels, you can never be the best at either. But being the tallest or having the most pixels does not ensure success. In basketball, a very tall person might lack coordination, athleticism, drive, intelligence, etc. just like a super high pixel count camera might be terrible in many other ways. More pixels can be useful but, just like height in basketball, smart 'scouts' should consider the whole package.

Call it Pixel Count

A simple solution would help a lot. Stop using 'resolution' and start saying 'pixel count'. Then users and specifiers can think more clearly what more pixels actually delivers.

Philip Starts here................

Pixel Count or resolution.... I call It Hi Res or Low res... and as mentioned..... Imagine a PERFORMANCE CAR...  How is the car evaluated...

1. great engine

2. great materials for car body 

3. great design

4. testing track


BUT how many count the factors for which they are mentioned. Its important to understand that the factors of measurement have changed a lot. Its important to understand that elements that make up the race track for a performance car is as important as the performance car itself.

In todays cameras market, the we forget about the race infrastructure.... We believe that if we give the fastest/ cheapest race car, the race is won.... but is it really? Its all about long term leadership....


My references may be confusing.... Lets discuss it... not about cars... about cameras..... 

revert back ... Will be a pleasure to discuss with you..
