2.0 FikeVideoAnalyticsSystemDesign
Thesystemdesignshouldincludethepropercoverageofthehazardareaaswellasmonitoringoftheeventsrecorded
bytheFVA‐IPcameras.Themonitoringcanbedonebyon‐sitesecurityoraremotemonitoringfacility.Thesystem
architectureisveryflexibletosuittheendusersneedsandcareshouldbetakenwhendesigningthesystemlayoutto
meettheneedsoftheenduser.Someexamplesofthevaryingarchitecturesinclude:

 WiringthecamerasdirectlytothedrycontactsofaFMapprovedFACP
 Connectingthecamerastoon‐sitemonitoringusingthecoaxortheLANconnection
 Configuringthecamerastoberemotelymonitoredbyathirdpartyorcorporatesite
 Usingavideomanagementsystemtorecordeventsforposteventanalysis

Anycombinationofarchitecturecanbecombinedtoproducethedesiredresults.
2.1 SystemDesign
NOTE:AlltherequirementsofNFPA72,includingbutnotlimitedto,back‐uppowerrequirements,maintenance
requirements,andperformance‐basedinstallationcriteriashouldbefollowed.
NOTE:Powerwith12‐24VDC(UL),12VDC(FM)fromULlistedClass2powersupplyforsecurityorfireshouldbeused.
POEmaybeusedassupplementaltothelisted12or24voltpowersupply.
TheFVA‐IPcamerashouldbeconnectedtoeitherPower‐Over‐Ethernet(POE)ora12/24VDC1A,Class2powersupply
certifiedforusewithsecurityandorfireapplicationsonly.Bothcanbeusedtogetherforredundancy.Electricalratings
canbefoundontheFVA‐IPcameras.Ifyouareunsureofcameraplacement,youmaywanttoperformaFireHazard
Analysis(FHA)andoraperformance‐baseddesignanalysistodeterminetheproperplacementandnumberofcameras
toadequatelyprotectthearea.Itisimportanttoconsiderthedesiredperformanceandpreventionofnuisancealarms.
Takeintoaccountpredictedsmokeflow,ceilingobstructions,configurationofcontents,lighting,anddesiredfiresizeat
detection.
Thelocationandspacingofcamerasshouldbetheresultofanengineeringevaluationthatincludes:
 Sizeandtypeoffiretobedetected
 Fuelinvolved
 Detectorsensitivity
 CameraFieldofView(FOV)
 Distancebetweenfireandcamera
 Purposeofthedetectionsystem
 Responsetimerequired
 Sourcesoflight
 Obstructions
The FVA‐IP camera relies on “seeing” smoke and flames.  The presence of intervening structural members and/or
intermittent opaque objects or materials in front of the cameras can compromise its ability to respond to the fire.
Obstructions in the cameras FOV are acceptable, as long as the obstructions do not compromise the ability of the
systemtodetectthedesiredfiresizeandtypeintheallottedresponsetime.Mountcamerastoensureobjectsthat
willappearlargetoitwillnotpassinfrontoforthroughitsFOV;forexample,apersonstandingcloserthan5ft.(1.5
m)pastthecameraoravehicleparkinginfrontofthecamera.
