Presentation Transcript

  1. Axis Communications Partner Training

  2. Agenda • Overview – (8:30am – 12:00pm) • Network camera housings • CCTV and surveillance demystified • Optics

  3. Camera Enclosures

  4. Overview • Rating systems • General considerations • Installation tips • Recommended enclosures • AXIS 290B Network Camera Housing • AXIS Fusion Dome

  5. Rating Systems • Many different systems • NEMA, IEC, UL, CSA… • Industry action groups/companies • Product design, performance and application • Common reference & interchangeability

  6. Rating Systems • International Electrotechnical Commission (IEC) • Consists of two letter prefix IP followed by two digits • Solid object ingress (first digit) • Liquid ingress (second digit) • Examples: • IP65 dust tight, heavy water spray • IP66 dust tight, heavy jet spray • IP54 dust resistant, splashing water

  7. Rating Systems: IEC • IP (First number) • 0: No special protection • 1: Solid objects > 50 mm diameter • 2: Solid objects > 12 mm diameter • 3: Solid objects > 2.5 mm diameter • 4: Solid objects > 1 mm diameter • 5: Dust protected • 6: Dust tight

  8. Rating Systems: IEC • IP (Second number) • 0: No special protection • 1: Dripping water • 2: Dripping water when tilted 15 degrees • 3: Spraying water • 4: Splashing water • 5: Water jet spray • 6: Heavy jet spray • 7: Immersion • 8: Submersion

  9. Rating Systems • National Electrical Manufacturers Association (NEMA) • Water ingress • Solid object ingress • Mechanical impact of enclosure on walls • Oil resistance • Corrosion resistance • Door and cover latching requirements

  10. Rating Systems: NEMA • 1: General purpose (indoor) • 2: Water drip proof (indoor) • 3R: Dust tight, rain tight, ice resistant (outdoor) • 4: Water tight and dust tight (indoor/outdoor) • 4X: Water tight, dust tight, corrosion resistant (indoor/outdoor)

  11. Rating Systems: NEMA • 9: Indoor hazardous locations • 12: Industrial use – drip tight and dust tight (indoor) • 13: Oil Tight and Dust Tight (indoor)

  12. General Considerations • Local codes • NEMA rating of 3, 3R, 4, 4X, 6, or 6P for outdoor • IP Rating 66, 65 • Resistance measurement • 4x rule

  13. Installation Tips • Consult wiring distance chart • Add up total VAC needed • Camera placement is important • Environmental conditions • Heater/blower combinations • Sun shrouds • Cabling considerations • Accessories • POL • AXIS 2191 Audio Module

  14. AXIS 2130R Enclosures • AXIS Outdoor Fusion Dome • Outdoor dome housing • Tinted lower dome • Heater and blower for outdoor use • AXIS Indoor Fusion Dome • Indoor dome housing • Tinted lower dome

  15. AXIS 2130R Enclosures • AXIS Indoor Recessed Enclosure • Low profile indoor ceiling housing • Can be installed in either sheetrock or drop ceilings • Tinted lower dome • AXIS Outdoor Vandal Fusion Dome • Offers vandal resistant protection in a compact size • Heater and blower for outdoor use • Made from durable cast aluminum

  16. Axis Fusion Dome - Pricing

  17. AXIS 290B Network Camera Housing • IP 65 classified – Protected against dust and heavy rain • Axis network cameras supported • AXIS 2120 Network Camera • AXIS 2420 Network Camera • AXIS 2110 Network Camera • Temperature range -4° F to +108° F • Integral tamper proof wall mounting bracket. • Integrated sunshield • 1 year limited warranty

  18. AXIS 290B - Pricing * Bundled products are not pre-assembled.

  19. Q & A • Questions and Answers

  20. CCTV Demystified

  21. CCTV Closed Circuit Tele Vision

  22. Video • Video is Latin and means “I can see” • A human eye will consider 16 frames per second to be ”real time” video • A CCTV system provides up to 30 frames per second

  23. Basic CCTV Systems Alarm I/O Monitor Switch VCR / Time Laps Cameras

  24. Transmission Medium • Wired • Coax – 75 ohm • RG 59 – 300 meter • RG 11 – 500 meter • Twisted-pair • 2-wire twisted – 1000 meter • Fiber-optics • Single mode or Multi-mode fiber • Long distance – >10,000 meter • Wireless • Laser link • Microwave • Radio link

  25. Fields and Frames Each frame of video information ismade up of 2 fields

  26. TV Standards • NTSC – National Television System Committee • First standard 1953 • 525 horizontal lines • 60 fields/sec = 30 frames/sec

  27. TV Standards in Countries • http://www.alkenmrs.com/video/wwstandards1.html • http://www.ee.surrey.ac.uk/Contrib/WorldTV/

  28. The Video Signal Theory • Composite video • The complete video includes all signals • Y/C video • Y is the luminance signal • C is the chroma signal • Gives a better image quality

  29. Resolution • Vertical resolution • Horizontal resolution • Analog cameras • 330-400 lines is normal – Low res • >460 lines is good quality – High res

  30. Resolution • Resolution measurement in the future • Digital cameras • 640x480 pixel • 1280x1024 pixel

  31. Lights • What is light? • Eye vs CCD • Natural light sources • Artificial light sources

  32. Main Items in a CCTV System

  33. CCTV Video Camera DSP • D/A • A/D • Analog • B&W or color • 1/4”, 1/3” or 1/2” CCD

  34. Camera Lens • Basic lens types • Manual iris • Automatic iris • Lens function • Fixed focal length • Varifocal length • Zoom lens • Lens / chip size • 1/3” • 1/2” • Mounting standards • CS-mount • C-mount

  35. Domes • A Dome camera combinesthe design elegance ofa dome enclosure, colorcamera, a fast pan and tiltmechanism andan environmental enclosure • The result is an “all-in-one” product • The trend has been very clearthe last years: • Fewer pan and tilt devices andmore Domes

  36. VideoMonitors • A monitor is very similar toa standard television set, however, it lacks the electronics to pick up regular television, the tuner • Monochrome – up to 1000 lines • Color – up to 800 lines • Market different between plastic-cased monitors and metal-cased monitors

  37. VideoRecorders • Time lapse VCR • A special slow recording VCR • Max 540,000 images (VHS standard) • Up to 960 hours on a single VHS tape • Controllable via RS-232 • VCR with DAT • Digital Video Recorder (DVR)

  38. Control Devices in CCTV

  39. Video Switchers • Units that provide automated as well as manual switching of full screen images • Larger units will normally also provide an ability to control dome cameras and PTZ’s • When one camera is on selected for recording, the other camerasare NOT being recorded at all

  40. Video Multiplexers • Multiplexer units are high-speed switchers that provide full-screen images from up to 16 cameras • Available in two models • Simplex • Duplex • Normally also provide the ability for viewing multiple cameras in 2x2, 4x4 etc

  41. Quads • A quad sends upto fourcameras tothe monitorand tothe recorder atthe same time, eachcameragets a quarter of the monitor • All of the information fromeach camera gets recordedbut ONLY in small quarter-screen clarity

  42. Accessories

  43. Housings • Outdoor • Indoor • Aluminium and plastic common • Blower, heater optional • Housings for special applications • Process industry • Explosion proof

  44. Pan and Tilt Head • A normal camera can be placed onpanandtilt devices whichwill allowthe camera to bemoved up, down, left and right from a remote location • A zoom lens will allow a closer view • In- and outdoor version

  45. Infrared (IR) Illuminator • IR light can not be seen by human eye • IR sensitive B&W cameras can see in darkness with IR light • Illuminators exist in two versions • Lamp-based • LED-versions • Distance to the object • 20W 10-15m • 300W 80-120m

  46. Q & A • Questions and Answers

  47. Lenses & Filters

  48. Lens and Optical Filter in a Camera

  49. Filters - IR Filter • Filters the infrared light invisible for the human eye but visible for cameras

  50. Filters - Optical Low Pass Filter • Splits the incoming light • Improves color representation
