A Short Discussion on High Resolution Cameras VICON A&E SUMMIT ‘09
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
Mega Terms Pixel PICture ELement Pixel count, expressed as megapixels Pixels Per Foot Progressive scan
VICON A&E SUMMIT ORLANDO, FLORIDA JAN , 2009 Megapixel Cameras Four Major Benefits –Higher definition = greater detail –More coverage with fewer cameras –Different aspect ratio = higher efficiency –Progressive scan = stable picture
Higher Definition = Greater Detail Live Viewing After the Fact Multi Views
Fewer Cameras with Greater Detail
Fewer Cameras with More Detail
Resolution Relationship 1289 X 1024 VGA 1.3 MP 720 X 480 VGA
Different Aspect Ratio = Higher Efficiency Record the picture that is needed
Interlaced Scan vs. Progressive Scan Interlaced Scan
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
Megapixel Trade-Offs Smaller pixels are normally less light sensitive Pixels Picture Element
New Camera; New Lens Lens Quality Optics true to the edges Chip/ Lens Alignment Back focus
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
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.
