A Short Discussion on High Resolution Cameras VICON A&E SUMMIT ‘09
2
Goals Understand new terms and technology Discuss megapixel camera benefits Discuss megapixel camera trade-offs Overview of new Vicon products Look at possible product applications
3
Mega Terms Pixel PICture ELement Pixel count, expressed as megapixels Pixels Per Foot Progressive scan
4
VICON A&E SUMMIT ORLANDO, FLORIDA JAN. 25-27, 2009 Megapixel Cameras Four Major Benefits –Higher definition = greater detail –More coverage with fewer cameras –Different aspect ratio = higher efficiency –Progressive scan = stable picture
5
Higher Definition = Greater Detail Live Viewing After the Fact Multi Views
6
Fewer Cameras with Greater Detail
7
Fewer Cameras with More Detail
8
Resolution Relationship 1289 X 1024 VGA 1.3 MP 720 X 480 VGA
9
Different Aspect Ratio = Higher Efficiency Record the picture that is needed
10
Interlaced Scan vs. Progressive Scan Interlaced Scan
11
Megapixel Trade-Offs Greater bandwidth and storage requirements Four or more times greater – But … a 3 MP camera can replace up to 3 standard cameras
12
Megapixel Trade-Offs Smaller pixels are normally less light sensitive Pixels Picture Element
13
New Camera; New Lens Lens Quality Optics true to the edges Chip/ Lens Alignment Back focus
14
Facts about lenses Most sellers of mega pixel cameras are selling “pixels” not image quality* –Standard Lenses are made for 489 TV Lines –Lens quality needs to equal camera quality Les Simmonds Security Electronics Magazine
15
Pixels Per Foot: It’s all about the details Two ways to get detail. 1.Get the camera closer 1.Bigger lens / Move the camera 2.Collect more data.

28
Vicon 1.3 Mega Pixel Cameras –Three times higher resolution –View larger areas –MJPEG or MPEG 4 compression –2-8 FPS In Megapixel mode –Progressive scan –POE –Currently electronic iris only –The PTZ and fixed zoom lens is not dead. Bottom Line
29
IP Cameras and License Issues If all your product is software you have to charge for usage…..Camera License $$$$ The Vicon plan –License Software (open platform) –Vicon cameras….no license –Third Party IP cameras license fee charged –ONLY ONCE! It is reusable
