1. What doesCCTV Stand for?
A commonquestioniswhatdoesCCTV stand for.However,itshouldalsobe whatdoesitstand for
and whatis the mostsuitable systemformyrequirements.CCTV standsforClosedCircuitTelevision.
The emphasisisonthe closed-circuitelement.
In contrastto televisionbroadcasting,whichisopenlybroadcast,CCTV istakenfroma setof
camerasand those broadcastsare enclosedwithinthatpersonorcompaniescontrol andview
The transmissionof the systemstartsat the camera endand isthentransmittedbackto a central
networkwhichcontrolsandactionsthe signals.These canbe viewedonalocal monitoror sentover
variousnetworks.These canthenbe viewedbyothercomputersinternallyorexternallyfromthe
premises.Alsowithmodernsystems,thesecamerascanbe seenviaa phone or tablet device.
The systemcan be a point-to-point(1camera to 1 networkcontroller).Furthermore,theycanbe a
point-to-multi-point.(Manycamerasbackto a single networkcontroller).Generally,these cameras
and networksare linkedviahard-wireddatacabling.However,manyCCTV camerasare now linked
and transmittedviaWi-Fi
Analogue CCTV
Legacy CCTV systemswouldtransfertheirsignalsviaanalogue signalsandoveracoaxial cable.In
addition,the camerawouldrequire poweringatthe camera end.However,astechnologyadvances,
the cameras were able totake two cablesfromthe networkserver.Firstly,the cable wouldreceive
the signals.Secondly,the additional cable wouldsendpowertothe camera to eliminate the
requirementstohave local power.Furthermore,thesecableswere abletocontrol certaincamera
types,sotheycouldpan,tiltand zoom.
In additiontothese limitationsonthe cabling,the camerasalsohadto go back to a signal pointin
the building.If differentlocationswere required,several separate videostorage unitswere required
and all separatelylinkedbacktothe central network
IP Based CCTV
ModernCCTV camerasare nowprimarilytransmittedoverstructuredcabling.A single Cat5e,Cat6,
Cat6a cable will be installedbetweennetworkswitchesandcameras.Furthermore,asthe systemis
basedon structuredcablingandIPnetworking,the camerascanlinkback toany networkswitchin
the building.Thisallowssmootherinstallationandmanagement.
In addition,asthe camerasare linkedvia structuredcabling,theycanbe poweredbyPoEovera
single cable.Therefore,thisresultsinlesscablingoverall toinstall aCCTV system
How CCTV is Used
Firstly,eachbuildingisunique andwill dependonthe size of the space and how manyareas need to
be covered.Inaddition,itwill dependonhow manyentryandexitpointsthere are.These canbe
lifts,stairs,entrydoors,andlimitedaccessareas.Secondly,itwilldependonthe requirementsfor
youto have imagesof your space.Thiscan be general coverage incase of occurrences.Itcan be fine-
tuningto monitorveryspecificspaces.Itcan be internal,orexternal,orboth.Forexample,ageneral
office will have fewercamerarequirementsthanacasino.Lastly,the requirementswill dependupon
the budget.Some areaswill be anecessityandothersa nice to have.The budgetwill guidehow you
