5.LENS SELECTION 6.CAMERA 7.MONITOR 8.DISPLAY
9.RECORD 10.INTEGRATED SYSTEM COMPREHENSION 11.AUDIT SYSTEM 12.CCTV DESIGN UNDERSTANDING
Teknologi dan Rekayasa CCTV ELEMENTS SYSTEM SIX DESIGN CONSIDERATION 1.Enviromental picture taking 2.Camera Lens 3.Transmission media 4.Monitor 5.Video signal management 6.Controller equipment
LIGHTING Without light in point camera can't perform task with every consideration which is give desirable image Based on lighting, available 2 camera types : –FULL VIDEO : –USABLE VIDEO
LENS Lens are optical component of system that describe picture screen include size, form and focus. Three factor of quality lens influence 1.Glass Absorption factor 2.Coating and Polishing 3.Mechanism
LENS SELECTION STEP FOR LENS SELECTION 1.Picture taking place identification, (to estimate with lens, broad estimation / vertical high picture taking) 2. Distance estimation of camera goes to picture taking place
3)Focal elongated computing of lens 4)Estimate horizontal's dimension and vertical area view critical 5)Determining area view critical measure in monitor 6)Choose for lens the most approaches requirement
CAMERA QUALITY DETERMINANT AND REABILITY OF CCTV SYSTEM Image censor resolution Signal Comparation to noise Automatic light compensation Synchronization Output signal Environmental conditions and camera reability Dimensions and weight
MONITOR Display ( monitor) criteria grouped in two category : Electronics factor Human interface factor
3 parameter that regard operator ability is engaged monitor efficiently : Display size Operator distance goes to to monitor = (Measure monitors (in inchi) – 4 = optimum visibilities +/- 25% (feet) Viewpoint
There is 3 type Monitor that frequent being used by various excess and its lack CRT LCD Plasma
