Fɛn fɔlɔ min bɛ kɛ ka ɛntɛrinɛti injiniyɛri baarakɛminɛn sugandi, o tɛ ka fɛn ɲɛfɔlenw lajɛ, nka ka kɔrɔbɔli kɛcogo ɲɛfɔ. Ko minnu bɛ kɛ cogoya wɛrɛw la, olu bɛ baarakɛminɛn suguya wɛrɛw de wajibiya pewu.

Fɔlɔ ka ɲɛfɔli kɛ: I bɛ mun kɔrɔbɔ tigitigi?

Fɛn fɔlɔ min bɛ kɛ ka ɛntɛrinɛti injiniyɛri baarakɛminɛn sugandi, o tɛ ka fɛn ɲɛfɔlenw lajɛ, nka ka kɔrɔbɔli kɛcogo ɲɛfɔ. Ko minnu bɛ kɛ, olu bɛ baarakɛminɛn suguya wɛrɛw de wajibiya pewu: sotigi mago bɛ se ka kɛ baarakɛminɛn ye min bɛ se ka ta dɔrɔn, min bɛ se ka kamera ka balofɛnw lajɛ, k’a sɔrɔ lakana injiniyɛri ŋana dɔ ka kan ka kamera tan ni caman minɛ waati kelen na, ka PoE fanga kɔrɔbɔ, ka PTZ kunkanko sɛgɛsɛgɛ, ani ka sɛgɛsɛgɛli rapɔɔriw dilan.

FangService ka ɛntɛrinɛti sɛgɛsɛgɛli minɛnw sira bɛ tali kɛ ko jɔnjɔn naani na: sɛgɛsɛgɛli basigilen min bɛ se ka ta (PK66 seriyali), bololabaarakɛla ka mobili sɛgɛsɛgɛli (PK67 seriyali), baarakɛlaw ka wideyow sɛgɛsɛgɛli (PK68 seriyali), ani ɛntɛrinɛti baarakɛminɛn dafalen (PK69 seriyali). Sugandili kun ye k’a faamuya gɛlɛya jɔnjɔn min bɛ seri kelen-kelen bɛɛ ɲɛnabɔ, sanni ka ɲɛminɛ ni fɛnw lisɛli ye.

Portable vs Professional: Volume-Function Jago

Danfara min bɛ se ka faamuya kosɛbɛ ɛntɛrinɛti injiniyɛri baarakɛminɛnw ni ɲɔgɔn cɛ, o ye hakɛ ni cogoya ye. PK66 seriyali ye bolokɔni ye, wa a bɛ se ka baara kɛ ni bolo kelen ye, a bɛnnen don mɔgɔ kelen ka sɛgɛsɛgɛli teliya ma. PK67 seriyali dilannen don ni bolokɔnincinin ye — a bɛ don i n’a fɔ watɛsi, ka bolo fila bɛɛ hɔrɔnya walasa i ka se ka baara kɛ ni bolo kelen ye k’a sɔrɔ i bɛ sɛgɛsɛgɛli jaabiw lajɛ ni bolo tɔ kelen ye, o bɛnnen don foro baara kuntaalajan ma. PK68 ni PK69 seriyali ye baarakɛlaw ka baarakɛminɛnw ye — ɛkran belebelebaw ani baarakɛcogo caman, nka u ka bon ani u ka gɛlɛn fana, u bɛnnen don baarakɛyɔrɔ jɔlenw ma walima bolifɛnw baarakɛcogo ma.

Tiɲɛ walima kojugu si tɛ volume-function tradeoff la — n’i ka porozɛw ye kɛrɛnkɛrɛnnenya la sɛgɛsɛgɛli ni ladonni ye sistɛmu sigilenw na kaban, portable walima wristband models bɛ fɛn caman di ni aw ka porozɛw ye debugging ni sɔnni ye kosɛbɛ sistɛmu kura sigilenw na, baarakɛlaw ka modɛliw ka sɛgɛsɛgɛli seko bɛ kɛ fɛn ye min nafa ka bon.

Wideyo cogoya dɛmɛni: IPC/AHD/TVI/CVI — Bɛɛ ka kan ka datugu

Rezo injiniyɛri baarakɛminɛnw seko jɔnjɔn dɔ ye ka wideyow cogoya caman dɛmɛ. IPC (IP Camera) bɛ wideyow nizɛri ci ɛntɛrinɛti kan, k’a sɔrɔ AHD, TVI ani CVI ye coaxial HD cikan fɛɛrɛ saba ye minnu tɛ kelen ye — u bɛɛ bɛ baara kɛ ni coaxial kabali ye minnu bɛ yen walasa ka HD wideyow ci nka u tɛ bɛn ɲɔgɔn ma.

FangService ka PK68 ni PK69 seriyali bɛ IPC, AHD, TVI, ani CVI dɛmɛ waati kelen na — cogoya naani. O kɔrɔ ye ko fɛɛrɛ mana kɛ ni fɛɛrɛ o kamera ye porozɛ dɔ la, o baarakɛminɛn kelen bɛ se ka balo jira k’a ɲɛsin a yɛrɛ ma. Porozɛ ɲagaminenw kama minnu bɛ kamera fɛɛrɛ caman ta (i n’a fɔ sistɛmu kɔrɔ dɔw minnu bɛ baara kɛ ni AHD ye ani sistɛmu kura minnu bɛ baara kɛ ni IPC ye), dɛmɛ min bɛ kɛ ni cogoya caman ye, o ye seko nafama ye.

PoE Testing: Ɛntɛrinɛti baarakɛminɛnw bɛɛ t’a dɛmɛ

PoE fanga sɛgɛsɛgɛli ye fɛn nafama ye nka a bɛ se ka fɔ ka ban nɔgɔya la, min bɛ sɔrɔ ɛntɛrinɛti injiniyɛri baarakɛminɛnw na. Baarakɛminɛn dɔw bɛ se ka kabali tɛmɛsira kɔrɔbɔ dɔrɔn, u tɛ PoE fanga paramɛtiriw suman. Ni aw ka porozɛ bɛ baara kɛ ni PoE kamera caman ye, baarakɛminɛn dɔ sugandi min bɛ PoE sɛgɛsɛgɛli dɛmɛ, o nafa ka bon.

FangService ka PK69 seriyali bɛ PoE sɛgɛsɛgɛli dafalen dɛmɛ — ka tension, current, ani power jira, ani ka kiri tigɛ ni kuran sɔrɔcogo bɛnnen don. PK68 seriyali fana bɛ PoE sɛgɛsɛgɛli dɛmɛ nka a baarakɛcogo nɔgɔyara kosɛbɛ. PK66 ni PK67 seriyali ɲɛsinnen bɛ kosɛbɛ wideyow sɛgɛsɛgɛli jɔnjɔnw ma, ni PoE sɛgɛsɛgɛli seko danma ye. Sugandili ka kan ka da PoE kamera hakɛ kan porozɛ kɔnɔ.

Baarakɛminɛnw sugandili musaka dogolenw

Ni i bɛ ɛntɛrinɛti injiniyɛri baarakɛminɛn dɔ sugandi, musaka jɛlen (minɛn sɔngɔ) ye maana tilancɛ dɔrɔn ye. Muɲu dogolenw ye : batiri muɲuli (minɛn salen kɔrɔ ye ko baara tɛ se ka kɛ), ɛkran kalanni yeelenba kɔrɔ (kɛnɛyako gɛlɛyaw kɛnɛma jɔli yɔrɔw la), fɛn wɛrɛw bɛnkan (yala kɔrɔbɔli kabɔriw sanni ka nɔgɔn ani ka u falen wa?), ani baarakɛminɛnw kalancogo. FangService ka rezo sɛgɛsɛgɛli minɛnw sira bɛ nin ko dogolenw jateminɛ a dilanni na — PK67 bolokɔni dilanni bɛ bolo fila bɛɛ hɔrɔnya, PK68 ni PK69 yeelenba ɛkranw bɛ bɛn kɛnɛma sigidaw ma, ani seri bɛɛ bɛ baara kɛ ni fɛnw ye minnu bɛ kɛ ni sariya ye walasa ka fɛnw falen nɔgɔya la. Baarakɛminɛn ɲuman sugandili tɛ minɛn sanni ye, nka baarakɛcogo ɲuman sanni ye. View the Network Test Instruments Collection
