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. 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

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

• PixelsPicture 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

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.

I-ONYX MP-955IR

• 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

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

Post Alarm Work

• Outdoor– School play grounds– Executive Parking areas– Corrections exercise areas

• Indoor– School Lunch

Rooms– Corrections Day

Rooms– Money handling
