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

32 ... M A K E Y O U R N E T W O R K S M A R T E R Main Items in a CCTV System

33 A/D D/ADSP CCTV Video Camera  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 combines the design elegance of a dome enclosure, color camera, a fast pan and tilt mechanism and an environmental enclosure  The result is an “all-in-one” product  The trend has been very clear the last years: ­ Fewer pan and tilt devices and more Domes

36 Video Monitors  A monitor is very similar to a 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 Video Recorders  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 ... M A K E Y O U R N E T W O R K S M A R T E R 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 cameras are 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 up to four cameras to the monitor and to the recorder at the same time, each camera gets a quarter of the monitor  All of the information from each camera gets recorded but ONLY in small quarter- screen clarity

42 ... M A K E Y O U R N E T W O R K S M A R T E R Accessories

46 Q & A  Questions and Answers

47 ... M A K E Y O U R N E T W O R K S M A R T E R 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

51 Filters – Example: Without Optical Low Pass Filter

52 Filters – Example: With Optical Low Pass Filter

53 The Lens

54 Angle of View  Same as “field of view”  What the camera with a given lens can “see”  Horizontal, vertical or diagonal

55 Lenses - Focal length  A small focal length gives wide angle view  A large focal length gives tele view

56 Lenses – Calculating the Focal Length  Which focal length is needed for the application? Calculating the focal length (f): f = h * D / H

57 Lenses – Depth of Field  The regions in front of and behind the focus point where the image remains in focus

58 Lenses - Aperture F numberf1.0f1.2f1.4f1.7f2.8f4.0f5.6 % of light passed 20%14.14%10%7.07%2.5%1.25%0.625%

59 Lenses – Lens Iris  Opening in the lens that controls the amount of incoming light that reaches the image sensor A wire between the camera and the lens is needed with an automatic iris lens.

60 Lenses - Lens Elements  A lens contains several lens elements  Aspherical elements reduces distortion

61 Lenses- Mount Standards  CS-mount ­ 12.5mm from camera edge to sensor  C-mount ­ 17.5mm from camera edge to sensor ­ Conversion C to CS is possible

62 Lenses – Sensor Dependency  The lens must make an image circle large enough to cover the sensor  Larger sensor = more expensive lens  The size (e.g. 1/3”) can not be measured anywhere - corresponds to old TV camera tubes  Low end lenses produce unsharp corners

63 Lenses - Resolution  A typical CCTV lens has a resolution of 100 lines/mm

64 Lab Exercise 1. Field of view calculation

65 Lenses – Types: Wide Angle  Large angle of view  Good in low light  Good depth of field  “Barrel” distortion  Not for long distances

66 Lenses – Types: Wide Angle Image Example  Example of barrel distortion & missing optical low pass filter

67 Lenses – Types: Telephoto  Good on long distance  No barrel distortion  Shallow (small) depth of field  Bad in low light

68 Lenses – Types: Vari-focal  The focal length can be adjusted  Needs refocusing after focal length adjustment  Less precision needed in focal length calculation

69 Lenses – Types: Zoom  Zoom – the focal length can be adjusted with maintained focus  Often motorized

70 Special Lenses – Fish Eye  Extremely wide angle (~180 deg) lenses are called “fish eye lenses”

71 Lenses – Example: Fisheye Image  A fish eye lens on a high resolution camera can work as a pan/tilt/zoom camera

72  Exit pupil is 1-3mm  Can be either low end $1 lenses or high end >$500 lenses Special Lenses – Pin Hole

73 Q & A  Questions and Answers

74 Agenda  Overview – (1:00pm – 4:00pm) ­ Designing IP-Surveillance solutions ­ AXIS Camera Station ­ Axis product roadmap

75 ... M A K E Y O U R N E T W O R K S M A R T E R Designing IP-Surveillance Solutions

76 The Basics  In some ways similar to analog: ­ What do we need to monitor? ­ When do we need to monitor it? ­ How many cameras are needed to cover? ­ How much video do we need to transfer? ­ How much video do we need to save? ­ Do we need to identify or detect?

77 What do we need to monitor ?  Define the scene(s) ­ Lighting conditions ­ Distances ­ Angle of view needed ­ High traffic or low traffic

78 When do we need to monitor it?  Same need to monitor day/night/weekend?  Schedule the needs for every “scene”

79 How many cameras are needed to cover?  Which types of cameras are needed? ­ Light sensitivity? ­ Video quality? ­ Which type of lens? ­ Speed? ­ PTZ? ­ IO needs?

80 How much video do we need to transfer? 30 fps transferred around the clock?

81 How much video do we need to save? 30 fps saved around the clock?

82 ... M A K E Y O U R N E T W O R K S M A R T E R The Network

83 LAN/WAN Inventory  Congestion level of current LAN  Congestion level of current WAN links  Schedule of congestion levels  Redundancy of WAN links

84 Network (LAN) New network or existing infrastructure? The answer might be in the needs discussed earlier

85 New Network (LAN)  Speed?  100 Mbit/s switches  1 Gbit/s Backbone

86 New Network (LAN)  Guidelines: ­ Calculate 30% extra capacity ­ Avoid cross-use with public (parallel) network as long as possible

87 New Network (WAN)  Share WAN links with the public network?  Extra links needed for redundancy?  Distributed storage needed?

88 Existing Network (LAN) Possible at all?

89 Existing Network (LAN)  “Mixed mode” ­ Separate network for backbone/main installation, public network where needed  VLAN ­ A “logical” way to separate the surveillance network from the public  QoS ­ Ensure the available bandwidth for surveillance equipment on the public network

90 Existing Network (WAN)  Use VPN’s? (compare with VLAN’s)  Distributed storage?  Nightly transfers of recorded material?

91 Conclusions  The basics still apply ­ Do a thorough inventory of the needs  High performance infrastructure equipment is dropping in price/usage complexity  Avoid “free” sharing with public networks  VLANS, QoS, VPN’s are excellent tools for a surveillance network
