Li nekk ci biir sistemu saytu kaaraange mooy 'ñuy gis te leer.' Fiil reso buñu nattwul dafay tekki ni xamoo ndax mën na joxe siñaal wideo HD ci anam wu dëgër, ndax mën na liggéey ci anam PoE, wala ndax amna ay dog wala ay balluwaayi interference ci digg bi. Ci wàllu ingenieur ci wàllu kaaraange, saytu reso bi du 'jéego buy yokk' — mooy lignéeru kaaraange bu mujj ngir kalite joxe gi.
Li ñu gëna bari luñu juum mooy fiil reso yu bees yi usine bi lañu leen natt te soxla wuñu yeneen natt. Ci dëgg, fiil yi mën nañu yàqu ci dem ak dikk, dencukaay, samp, ak jeexal - rayon coudé bu ëpp, doole xëcc, xoosu ci catu ñaw, loose RJ45 crimping - lépp mën na yàq performance lëkkaloo. Bu jëfandikukat bi waxee ni 'nataalu kameraa bi dafay tëju' wala 'PTZ bi wëréeluwul,' li ko waral dafay jafe lool ngir xam fimu joge.
PoE (Power over Ethernet) benn la ci xarala yi gëna am solo ci sistem yiy saytu kaaraange. Kamera yi dañuy joxe done yi ak kuuraŋ bi ci benn fiil reso, suko defee doo fay xaalis bu bari wala jafe-jafe yi ci nekk ngir joxe kuuraŋ bu moom boppam. Waaye, PoE dafay laaj lu gëna rëy ci kalite lëkkalekaay bi gëna bari ci joxe done yu sell - doole ju doywul mën na tax kamera yi tàmbaliwaat, wane nataal yu jaarul yoon, wala sax dem offline.
Test PoE yamul ci xool ndax fiil bi dafay jaar; Dafay laaj itam nga natt voltage biy joxe, courant bi ak doole ji. Fiil bu am 80 meetar ak jauge bu woyof wala résistance bu baaxul ci konektër bi mën na tax voltage PoE bi ci catu kamera bi wàcci ba ci suufu threshold biy dox. Ci FangService jumtukaayi test reso, jumtukaayu ingenieur reso PK69 dafay jàppale PoE doole test, di wane voltage, courant, ak done doole ci jamono dëgg ngir jàppale insiñër yi ñu gaaw xam ndax lëkkalekaay bi méngoo na ak dooley PoE.
Ci wàllu ingenieur yiy saytu kaaraange, li gëna bari luñu koy saytu mooy xool siñaalu wideo bi ci kameraa bi. Li ñu gëna xam mooy nga boole kameraa bi ak monitër wala ordinatër, nga xool ak sa loxo ndax nataal bi leer na te melo yi jaar nañu yoon. Bokk na ci anam yii amul njariñ, mingi aju ci xalaatu ki koy saytu.
Jumtukaayi ingenieur reso yu bees yi dañu boole ay fonction test siñaal wideo. FangService's PK68 series professionel wideo tester jàppale IPC, AHD, TVI, ak CVI format wideo coaxial HD yu bari, te mën na wane nataalu kamera bi ci saasi te du boole ci ordinatër, ak jumtukaayi jàngat (lu melni jàngat melo, test grayscale, ak distorsion). Jumtukaayu ingenieur PK67 series ak jumtukaayu ingenieur portable series PK66 ñoo méngoo ak senaario instalaasioŋ yu gëna ndaw, suko defee benn nit mëna def test bi.
Ci sistem yiy saytu kaaraange, PTZ (Pan-Tilt-Zoom) mooy wuutale 'mën gis' ak 'mën jëfandikoo.' PTZ siñaal yi ñuy jëfandikoo dañuy jaar ci bus RS485 - ñaari yeneen fiil yu ñuy jëfandikoo (wala ñaari fiil yu amul liggéey yuñ boole ci fiil reso bi).

FangService's reso test jumtukaay ligne - PK69 ak PK68 series - ñoom ñaar jàppale RS485 PTZ test njiitu, mëna yónnee komànd njiitu ak xool tontu PTZ. Dañuy jàppale position yiñ tëral bu njëkk ak fàttaliku, jàppale ingénieur yi ñu gaaw ci gis njuumte yi ci doxal PTZ.
