1. High Mega-Pixel Display and Recording
How to best utilize high mega-pixel cameras
Guy Arazi: Director of Products

2. UDERSTANDING THE NEW RESOLUTIONS
Cameras offer higher resolutions than before
Each video frame is significantly larger
Bandwidth is higher
Storage needs are growing

3. RELATIVE FRAME SIZES 5.7 times larger than 2MP 39 times larger than D1

4. ASPECT RATIO
When mega pixel cameras took us out of the VGA / D1 zone, the aspect ratio shifted
Where 4:3 ratio dominated the industry in the past, wide 16:9 took the lead
Some resolutions like the 12MP are still 4:3
The industry adopted wide screen monitors
Good VMSs offer aspect ratio correction and allow to utilize both

5. ASPECT RATIO AND FIELD OF VIEW
12M image 4:3
8M image 16:9

6. FIELD OF VIEW AND PIXELS PER FOOT
With more pixels in every image we now can
Increase the field of view
Cover a wider area with each camera
Still have enough Pixel per foot
PPF = Picture Density = Detail

7. WHAT DOES PPF OFFER US?

8. WIDER FOV WITH SAME PPF
Number of horizontal pixels on camera Number of required Pixels−per−foot = Effective horizontal FOV
Example using 40ppf

9. ALWAYS USE 8MP AND 12MP? Not every camera needs to be 8 or 12MP
In some applications, these will be an expensive overkill
Using these in the right area will allow maximizing their capabilities

10. WHERE NOT TO USE Typically you will not use 8 and 12MP in
Standard indoor views such as a lobby
Small low details area to cover such as an office
Scenes where the detail is not required

11. WHERE TO USE Scenarios that will benefit from 8 and 12MP
Requirement for forensic detail such as money counting
Wide area shots such as a fence line

12. NEED TO HAVE GREAT DETAIL

13. NEED TO ZOOM IN TO SEE BETTER

14. NEED TO PICK REMOTE DETAILS

15. BANDWIDTH AND STORAGE 8 and 12MP cameras have larger images
They utilize higher bandwidth and require more storage than lower resolution ones as well as require more recording resources
Attention in the design will allow utilizing the cameras without overloading the system
If we use the standard road and traffic analogy, if the 2MP video streams are sedans driving on the road and 5MP are SUVs, the 12MP camera is a full size truck. It takes up more space on the road and will need larger parking spots to park at night.

16. DESIGN TIPS
These cameras come with a 1Gbps network port so can use a higher speed switch!
If you now cover and area that would require ~3 HD cameras, you should look at total bandwidth for the system
With a great picture, you can afford slightly lowering the FPS

18. DISPLAY CHALLANGES
Displaying these images requires more of the PC resources than before
The total number of these cameras a PC can display is lower than smaller resolutions
Older PCs (~2 years) might not be able to display these at all

19. HOW TO HANDLE DISPLAY When adding these cameras update the PCs
Utilize the camera’s secondary stream for split screen display
For continues full screen displays, dedicate a decoder PC

20. DISPLAY ON 1080P MONITORS

21. DO I NEED A 4K MONITOR
8 and 12MP cameras will display on lower resolution monitors (scaled down by the PC)
Using a 4K monitor can be an advantage:
Displaying an 8MP camera full screen
Displaying a 12MP camera full screen (slightly scaled down but less than on 1080P)
Displaying P cameras in a quad

23. The new cameras offer much higher resolutions
In many applications these resolutions can bring better FOV with superior PPF
Designing the system to handle these cameras well is key to utilize them well
The potential forensic value these bring combined with a built for security design and pricing offer great new uses.
