As bilong wanpela sekyuriti monitoring sistem em i 'lukluk na klia.' Wanpela netwok kebol we ol i no bin testim yet i min olsem yu no save sapos em inap long salim ol HD vidio signal gut, sapos em inap long wok aninit long PoE pawa mod, o sapos i gat ol bruk o ol samting i save bagarapim namel.
As bilong wanpela sekyuriti monitoring sistem em i 'lukluk na klia.' Wanpela netwok kebol we ol i no bin testim yet i min olsem yu no save sapos em inap long salim ol HD vidio signal gut, sapos em inap long wok aninit long PoE pawa mod, o sapos i gat ol bruk o ol samting i save bagarapim namel. Insait long sekyuriti kebol enjiniaring, netwok tes em i no wanpela 'ekstra step' — em i laspela lain bilong difens bilong kwaliti bilong deliveri.
Wanpela tingting kranki we planti manmeri i save kisim em olsem ol nupela netwok kebol em ol i save testim long faktori na ol i no nidim moa tes. Tru tumas, ol kebol inap bagarap taim ol i karim, putim, putim, na pinisim — bikpela 'bend radius', strong bilong pulim, ol mak long ol sap arere, 'loose RJ45 crimping' — olgeta dispela inap long bagarapim wok bilong ol 'link'. Long taim wanpela yusa i ripot olsem 'piksa bilong kamera i toktok planti' o 'PTZ i no tantanim,' planti taim em i hat long painim as bilong dispela hevi.
PoE (Power over Ethernet) em i wanpela bikpela teknoloji insait long ol sekyuriti monitoring sistem. Ol kamera i save salim data na pawa long wanpela netwok kebol tasol, na dispela i save rausim pe na hevi bilong indipenden pawa kebol. Tasol, PoE i putim bikpela askim long 'link quality' winim 'pure data transmission' - sapos i no gat inap pawa dispela inap long mekim ol kamera i stat gen planti taim, soim ol piksa we i no stret, o i go oflain olgeta.
PoE testing em i no bilong sekim sapos kebol i wok gut o nogat; em i nidim tu long skelim saplai voltej, karent, na pawa. Wanpela 80-mita kebol wantaim liklik waia gej o nogut konekta kontek resistans inap long mekim PoE voltej long arere bilong kamera i pundaun aninit long mak bilong wok. Namel long ol 'network testing instrument line' bilong FangService, PK69 series netwok enjiniaring tul i sapotim PoE pawa tes, na i soim 'real-time voltage', karent, na pawa data long helpim ol enjinia long painimaut hariap sapos link i inapim ol PoE pawa rikwaemen.
Insait long sekyuriti monitoring enjiniaring, bikpela wok bilong testim em long sekim vidio signal bilong kamera. Pasin bilong bipo em long konektim kamera long monita o kompyuta na skelim long han sapos piksa i klia na kala i orait. Dispela rot i no gutpela na i dipen long tingting bilong man i testim.
Ol nupela netwok enjiniaring tul i save bungim ol wok bilong sekim ol vidio signal. FangService's PK68 series profesenel vidio testa i sapotim IPC, AHD, TVI, na CVI planti 'coaxial HD' vidio fomat, na i ken soim piksa bilong kamera stret na i no konektim long kompyuta, wantaim ol 'overlay analysis tools' (olsem kala analisis, 'grayscale test', na 'distortion detection'). PK67 series wristband engineering tool na PK66 series portable engineering tool em ol i gutpela long ol liklik instolesen senario, na larim wanpela man tasol long pinisim tes.
Insait long ol sekyuriti monitoring sistem, PTZ (Pan-Tilt-Zoom) kontrol em i nambawan samting we i save soim olsem 'ken lukim' na 'ken yusim'. Ol PTZ kontrol signal i save go long RS485 bas — tupela moa kontrol waia (o ol 'idle waia' we i stap insait long netwok kebol). Ol rong bilong RS485 waya (olsem A/B lain i senis), ol 'terminal resistor' i no stap, o 'baud rate' i no stret, olgeta dispela inap long kamapim PTZ kontrol feil o 'latency'.
FangService's netwok tes instramen lain — PK69 na PK68 series — tupela i sapotim RS485 PTZ kontrol tes, inap long salim ol kontrol komand na sekim PTZ bekim. Ol i sapotim preset posisen seting na rikol, na helpim ol enjinia long painim hariap ol PTZ kontrol rong. Insait long ol bikpela sekyuriti projek, PTZ kontrol tes em i samting we ol i save lusim tingting long en tasol em i bikpela samting tru — sapos ol i no inap long kontrolim PTZ bihain long ol i givim, ol kos bilong stretim hevi i ken winim kos bilong pulim gen ol kontrol lain.
Pe bilong baim ol 'network testing tools' em i liklik tru taim yumi skelim wantaim ol lus we ol i save stopim. Wanpela namel sais sekyuriti monitoring projek i ken involvim planti o planti handet kamera — sapos wok bilong testim wanwan kamera i kostim planti ten yuan, na sapos ol i painimaut wanpela 'link fault' we ol i no painim bihain long projek i pinisim i ken kostim planti tausen o ten tausen long stretim hevi na stretim, ekonomik veliu bilong tes em i klia tru.
Bikpela samting moa, ol tes data yet i gat longpela taim veliu. Wanpela link we ol i bin testim wantaim ol rekot PoE pawa paramita, vidio signal kwaliti, na PTZ kontrol status ol i ken skelim hariap long taim bilong mentenens long bihain taim: 'dispela link i bin gutpela taim ol i bin givim?' o 'dispela link i gat ol hevi i stap hait taim ol i salim i kam?' Ol link we ol i no bin testim em ol i olsem ol blakpela bokis long taim bilong mentenens. FangService's netwok tes instramen lain i karamapim olgeta nid stat long besik konektiviti verifikasen i go long edvans vidio analisis, na helpim ol enjiniaring tim long kamapim ol tes standet stat long stat bilong wanpela projek.
