Mafi sauƙin abin kulawa na gwajin kyamarar IP shine shiri. Kafin ɗaukar sabuwar kyamara, tabbatar da abubuwa uku tukuna.

Shiri Kafin Gwaji

Mafi sauƙin abin kulawa na gwajin kyamarar IP shine shiri. Kafin ɗaukar sabon kyamara, tabbatar da abubuwa uku da farko: ① Abubuwan buƙatun wutar lantarki na PoE na kyamara (kewayon ƙarfin lantarki, matsakaicin yawan wutar lantarki); ② yanayin cibiyar sadarwa (ko tashar tashar tashar tana goyan bayan PoE, daidaitawar VLAN, iyakokin bandwidth); ③ makasudin gwaji (waɗanda ayyuka ke buƙatar tabbaci - bidiyo, PTZ, ƙararrawa I/O, samun dama mai nisa).

FangService's PK69 jerin kayan aikin injiniya na cibiyar sadarwa yana nuna matsayin haɗin gwiwar PoE na yanzu yayin duban kai na taya, gami da samun ƙarfin lantarki da matsakaicin ƙarfin samarwa. Idan ƙimar wutar lantarki ta kyamarar tana kusa da iyakar iyawar hanyar haɗin gwiwa, ya kamata a lura da wannan a cikin rahoton gwaji - ba lallai ba ne yana nufin matsala, amma yana iya zama cikas yayin haɓakawa ko ƙara kayan aiki a nan gaba.

Tabbatar da Wutar PoE: Daga Wutar Lantarki zuwa Margin

Tabbatar da ikon PoE shine mataki na farko a gwajin kyamarar IP kuma mafi sauƙin tsallake matakin. Mutane da yawa suna ɗauka 'idan sauyawa yana goyan bayan PoE, kyamarar za ta yi aiki lafiya.' A zahiri, ikon PoE shine batun injiniyan tsarin - guntu na PoE mai sauyawa, ma'aunin waya na USB da tsayi, ingancin crimp RJ45, da da'irar sarrafa wutar lantarki ta kyamara - duk wata gazawar hanyar haɗin gwiwa na iya haifar da rashin isasshen ƙarfi.

Daidaitaccen gwajin PoE ya kamata ya ci gaba a cikin matakai uku: ① auna ƙarfin fitarwa na juyawa-ƙarshen (yawan kewayon al'ada yawanci 44-57V DC); ② auna ƙarfin shigarwa na ƙarshen kyamara (idan kebul ɗin ya yi tsayi da yawa ko ma'aunin waya ya yi ƙarfi sosai, ƙarfin lantarki yana raguwa sosai); ③ ƙididdige ƙimar wutar lantarki (canja-ƙarshen ƙarfin lantarki rage ƙarfin ƙarfin kyamara-karshen ƙarfin lantarki yana daidai da raguwar wutar lantarki na USB). Gabaɗaya, digon wutar lantarki bai kamata ya wuce 5V ba - idan kebul na mita 80 ya haifar da raguwar ƙarfin lantarki da ya wuce 5V, yana nuna ƙimar ingancin kebul ko matsala. FangService's PK69 da PK68 jerin duka suna goyan bayan ma'aunin ma'aunin PoE da na yanzu, suna taimakawa injiniyoyi cikin sauri kammala waɗannan matakan uku.

Binciken ingancin Bidiyo: Bayan 'Duba Hoton'

Gwajin ingancin bidiyo shine ginshiƙan gyaran kyamarar IP. Ganin hoton shine kawai mataki na farko; tantance ko hoton ya 'cancanci' yana buƙatar ƙarin ƙima na tsari. Ma'auni masu mahimmanci sun haɗa da: ƙuduri (1080P vs 4MP vs 8MP), ƙimar firam (ainihin 25fps vs 15fps vs 10fps), bitrate (bitrate na yau da kullun CBR vs m bitrate VBR), haifuwa launi (aiki ƙarƙashin yanayin haske daban-daban), da latency (lokacin daga hoton kyamara don nunawa). FangService's PK68 jerin ƙwararrun mai gwada bidiyo na goyan bayan kayan aikin bincike mai rufi - yana iya nuna bayanan ƙididdiga masu launi, ƙirar gwajin launin toka, da gano murdiya akan hoto mai rai. Waɗannan kayan aikin suna taimaka wa injiniyoyi su kammala ainihin ƙimar ingancin bidiyo ba tare da kwamfuta ba. Don al'amuran da ke buƙatar ƙarin bincike na ci gaba (kamar ƙimar ƙaramar amo, gwaji mai faɗi mai ƙarfi), ana ba da shawarar yin amfani da ƙwararrun software na kwamfuta tare.

Ikon PTZ da Ƙararrawa I/O: Na'urori na ci gaba Sau da yawa ana kula da su

Bayan watsa bidiyo na asali, kyamarorin IP yawanci suna da ikon sarrafa PTZ, shigarwar ƙararrawa/fitarwa (Ƙararrawa I/O), da kuma sauti na hanya biyu. Waɗannan ayyuka galibi ana tabbatar da su ne kawai a lokacin shigarwa amma suna iya fallasa matsaloli yayin amfani na ainihi.

Rashin gazawar sarrafa PTZ na gama gari sun haɗa da: RS485 A/B juyawar layi (wanda ke haifar da PTZ don kada jujjuyawa ko juyawa baya), rashin daidaituwar ƙimar baud (PTZ yana amsawa a hankali ko a'a kwata-kwata), da ƙarancin saiti (buƙatun aikin sun wuce tallafin kyamara). Ƙararrawar I/O gama gari sun haɗa da: al'amurran da suka dace da wutar lantarki a tashoshin shigar da ƙararrawa (ayyukan ƙararrawa masu aiki da na'urorin ƙararrawa) da kurakuran daidaitawar software a cikin ƙararrawa. FangService's PK69 da PK68 jerin suna goyan bayan gwajin sarrafa RS485 PTZ, mai ikon aika umarnin sarrafawa da tabbatar da amsawar PTZ. Gwajin I/O na ƙararrawa yana buƙatar daidaitawa tare da takamaiman ƙirar kyamara da kayan ƙararrawa. Kafin isar da aikin, ana ba da shawarar yin cikakken tabbacin abu-da-abu na duk abubuwan ci-gaba - kar a jira har sai abokin ciniki ya ba da rahoton 'PTZ ba zai amsa' don gano matsalar ba.

Makomar Gwajin Kyamarar IP

Kamar yadda kyamarorin AI suka zama ruwan dare, gwajin kyamarar IP na fuskantar sabbin ƙalubale. Kyamarar AI ba kawai game da 'harbi a sarari' ba - mafi mahimmanci, sun kasance game da 'fahimtar abin da aka harbe.' Ba za a iya gwada ayyuka kamar tantance fuska, nazarin ɗabi'a, da tantance farantin lasisi ba kawai ta hanyar hukuncin hoto na hannu; ana buƙatar kayan aikin bincike na musamman. Layin gwajin gwajin cibiyar sadarwa na FangService a halin yanzu yana mai da hankali kan samar da barga, ingantaccen dandamali na kayan masarufi (PK66/PK67/PK68/PK69), yana rufe cikakkun bukatun daga gwajin bidiyo na asali zuwa bincike na PoE na gaba. Kamar yadda kyamarori na AI da ayyukan bincike na hankali suka zama mafi yawa, kayan aikin gwaji kuma za su buƙaci haɓaka daidai da haka - faɗaɗa daga 'tabbatar da ingancin sigina' zuwa 'tabbatar da daidaiton bincike.' Ga ƙungiyoyin injiniya na yanzu, zabar kayan aiki tare da ayyuka masu ƙarfi da ƙarfin faɗaɗawa ya fi dacewa fiye da bin sabbin samfura, mafi wayo. View the Network Test Instruments Collection
