2.4 EnvironmentalConsiderations
TomaximizethefiredetectionpotentialoftheFikeVideoAnalyticssystem,thecameralensesshouldbeproperlyset
upto ensuresharpimages.UsingaportableTVwiththeBNCconnectionattachedtothebackoftheIPcamerawill
allow localized adjustment to optimize the image focus.  Lenses should be clean and free of scratches.  Camera
positioningshouldconsiderlight saturationandconsistency,mountingintegrity,humidity, airborneparticulates,and
otherpotentiallydamagingambientconditions.Brightlightsourcesshouldbelocatedbehindthecameras.
The area to be protected should be uniformly illuminated; fluctuations caused by natural light should be limited.
Camerasshouldbesecurelymountedtopreventvibration,swinging,andothercameramotion.Excesshumiditymay
causefoggingofthelensesthatmaytriggerthesystem.
Makeprovisionto sustain camera lens clarity in applications whereairborne particulates and aerosols may coat the
cameralens betweenmaintenanceintervalsandaffectsensitivity.Camerasshouldbeprotectedeitherbydesignor
installationtoensurethatperformanceisnotcompromised.Whenusedinconditionsthatwillexposethecamerato
extremeconditions,thecamerasshouldbeshieldedorotherwisearrangedtomaintainperformancewhenexposedto
thoseextremeconditions.Thecamerasshouldnotbeinstalledinalocationwhereambientconditionsareknownto
exceedtheextremesfor which they have been listed (see specificationsAppendixA). Nuisance sources includebut
maynotbelimitedtowelding,modulatedlightsources,andlocalizedfluctuationsinlighting.Theareatobeprotected
shouldbeuniformlylitattheULminimumof1foot‐candle(10lux)measuredatthefloorlevelforthehazardareaor
the FM approved 4.8 Fc (~48 lux) at 30 inches (76 cm) above thefloorsurface.Generallightingshallmeetthe
minimumemergencylightingrequirementsofNFPA101(1Fc(10Lux))andshallnotproducealowlightcamerafault.
2.5 SelectingCable
Thereareseveralclassificationsofcableusedfortwisted‐pairnetworks.WerecommendCategory5(orCAT5)cable
forallnewinstallations.ThereareseveralfirecodeclassificationsfortheouterinsulationofCAT5cable.CMRcable,
or"risercable,"isthemostcommon,however,CMPorplenumcableisalsoavailableandmayberequiredbylocal,
stateornationalcodesifitwillberunningthroughsuspendedceilings,ducts,orotherareas,thatareusedtocirculate
airoractasanairpassagefromoneroomtoanother.Stranded wire patch cables are often specified for cable
segmentsrunningfromawalljacktoaPCandforpatchpanels.Theyaremoreflexiblethansolidcorewire.
CAT5cablehasfourtwistedpairsofwireforatotalofeightindividuallyinsulatedwires.Eachpairiscolorcodedwith
onewirehavingasolidcolor(blue,orange,green,orbrown)twistedaroundasecondwirewithawhitebackground
andastripeofthesamecolor.Thesolidcolorsmayhaveawhitestripeinsomecables.Cablecolorsarecommonly
describedusing the backgroundcolor followed by thecolorofthestripe;e.g.,white‐orangeisacablewithawhite
backgroundandanorangestripe.
The straight through andcross‐over patch cables are terminatedwithCAT5,RJ‐45modularplugs.RJ‐45plugsare
similartothoseyou'llseeontheendofyourtelephonecableexcepttheyhaveeightversusfourorsixcontactsonthe
endoftheplugandtheyareabouttwiceasbig.MakesuretheyareratedforCAT5wiring.(RJmeans"Registered
Jack").Also,thereareRJ‐45plugsdesignedforbothsolidcorewireandstrandedwire.Othersaredesignedspecifically
foronekindofwireortheother.Besureyoubuyplugsappropriateforthewireyouaregoingtouse.
