Labɛnni Sani sɛgɛsɛgɛli ka kɛ

IP kamera sɛgɛsɛgɛli fan min bɛ ye nɔgɔya la, o ye labɛnni ye. Sani aw ka kamera kura ta, aw bɛ fɛn saba dafa fɔlɔ: 1 kamera ka PoE fanga wajibiyalenw (voltage range, maximum power consumption); 2 réseau sigida (ni switch port bɛ PoE dɛmɛ, VLAN labɛnni, bandwidth danw); 3 sɛgɛsɛgɛli kuntilenna (baara minnu mago bɛ sɛgɛsɛgɛli la — wideyow, PTZ, alarma I/O, yɔrɔjan sɔrɔli).

PoE Seko ni dɔnko sɛgɛsɛgɛli: Ka bɔ Voltage la ka se Margin ma

PoE fanga sɛgɛsɛgɛli ye IP kamera sɛgɛsɛgɛli fɛɛrɛ fɔlɔ ye ani fɛɛrɛ min bɛ tɛmɛ nɔgɔya la. Mɔgɔ caman b’a miiri ko ‘ni switch bɛ PoE dɛmɛ, kamera bɛna baara kɛ ka ɲɛ.’ Tiɲɛ na, PoE fanga ye sistɛmu injiniyɛri ko ye — switch ka PoE puce, kabɛl wire gauge ani a janya, RJ45 crimp quality, ani kamera ka fanga ɲɛnabɔli circuit — ni ɲɔgɔndan kelen o kelen tiɲɛna, o bɛ se ka kɛ sababu ye ka fanga dɔgɔya.

PoE sɛgɛsɛgɛli ɲuman ka kan ka taa ɲɛ ni fɛɛrɛ saba ye: 1 ka switch-end bɔli wulicogo suman (a ka c’a la, a hakɛ bɛ kɛ 44-57V DC ye); 2 kamera laban donna tension suman (ni kabali janya kojugu walima ni nɛgɛ jateminɛnan ka fin kojugu, tension bɛ jigin kosɛbɛ); 3 ka jatebɔ kɛ tension margin (switch-end voltage minus camera-end voltage bɛ bɛn kabali voltage drop ma). A ka c’a la, tension jigin man kan ka tɛmɛ 5V kan — ni mɛtɛrɛ 80 kabɔri bɛ kɛ sababu ye ka tension jigin ka tɛmɛ 5V kan, o bɛ kabali jogo walima crimping gɛlɛya jira. FangService ka PK69 ni PK68 seriyali fila bɛɛ bɛ PoE tension ni current sumani kɛ waati yɛrɛ la, o bɛ ɛntɛrinɛti injiniyɛriw dɛmɛ u ka nin fɛɛrɛ saba in kɛ joona.

Wideyo jogoɲumanya sɛgɛsɛgɛli: ‘Ja lajɛ’ kɔfɛ.

Wideyo jogoɲumanya sɛgɛsɛgɛli ye IP kamera sɛgɛsɛgɛli kunba ye. Ja in yecogo ye fɛɛrɛ fɔlɔ dɔrɔn de ye; k’a dɔn ni ja in ‘seginlen don’, o bɛ jateminɛ kɛcogo sigilen de wajibiya. Jateminɛ jɔnjɔnw ye : ɲɛfɔli (1080P ni 4MP ni 8MP), frame rate (waati yɛrɛ la 25fps ni 15fps ni 10fps), bitrate (bitrate constant CBR vs variable bitrate VBR), kulɛri lasegincogo (baara kɛcogo yeelen cogoya wɛrɛw la), ani latency (waati min bɛ bɔ kamera ja la ka taa a jirali la).

PTZ Control ani Alarm I/O: Fɛn minnu bɛ kɛ ka ɲɛ, olu bɛ ye tuma caman na

Wideyo cikan jɔnjɔn kɔfɛ, a ka c’a la, IP kameraw bɛ PTZ kunnafoni, alarma doncogo/bɔcogo (Alarm I/O), ani mankan min bɛ kɛ sira fila fɛ. A ka c’a la, o baara ninnu bɛ sɛgɛsɛgɛ basigilen dɔrɔn na sigili waati nka u bɛ se ka gɛlɛyaw bɔ kɛnɛ kan baarakɛcogo yɛrɛ la.
