Makina oteteza makamera a IP abweretsa zabwino zambiri pamsika kuyambira pomwe adayambitsidwa, koma chitukuko sichinakhale bwino nthawi zonse. Kwa zaka zambiri, opanga mavidiyo akhala akukumana ndi zovuta zokhudzana ndi zida.
Protocol imodzi yapadziko lonse lapansi idayenera kuthana ndi vutoli pophatikiza zinthu zopangidwa ndi opanga osiyanasiyana mkati mwa dongosolo limodzi, kuphatikiza makamera othamanga kwambiri a PTZ, zida zokhala ndi ma lens a varifocal ndi zoom lens, multiplexers, ndi makanema ojambula pa intaneti.
Komabe, mpaka pano, ma protocol akomwe opanga zida zamakanema amakhalabe oyenera. Ngakhale mu chipangizo cha Ivideon Bridge, chomwe chimakupatsani mwayi wolumikiza β98% yamitundu yamakamera kumtambo, timapereka luso lapadera pogwira ntchito ndi ma protocol achilengedwe.
Chifukwa chiyani izi zidachitika komanso maubwino otani omwe ali nawo, tifotokozanso pogwiritsa ntchito chitsanzo chophatikizana ndi Dahua Technology.
Single muyezo
M'mbiri yakale, kupanga njira yabwino kwambiri yomwe imagwirizanitsa njira zothetsera malonda kuchokera kwa ogulitsa angapo zafuna ntchito yaikulu yophatikizana.
Pofuna kuthetsa vuto la kusagwirizana kwa zida, mulingo wa Open Network Video Interface Forum unapangidwa mu 2008. ONVIF idalola opanga ndi oyika kuti achepetse nthawi yokhazikitsa zida zonse zamakanema.
Ophatikiza madongosolo ndi ogwiritsa ntchito omaliza adatha kupulumutsa ndalama pogwiritsa ntchito ONVIF chifukwa cha kusankha kwaulele kwa wopanga aliyense pokulitsa dongosolo kapena kusintha pang'ono zigawo zake.
Ngakhale kuthandizidwa ndi ONVIF kuchokera kwa opanga zida zonse zotsogola zamakanema, pafupifupi kampani iliyonse yayikulu imakhalabe ndi protocol yachilengedwe ku kamera iliyonse ndi chojambulira makanema cha wopanga.
Dahua Tech ili ndi zida zambiri zomwe zimathandizira pa onvif ndi proprietary Dahua Private protocol, zomwe Dahua amagwiritsa ntchito popanga zovuta zotetezera kutengera zida zake.
Native protocols
Kusowa kwa zoletsa zilizonse ndi mwayi wa chitukuko mbadwa. Muzomangamanga, wopanga amayang'ana pa "zinthu" zomwe amaziona kuti ndizofunikira kwambiri, kuthandizira mphamvu zonse za hardware yake.
Chotsatira chake, ndondomeko yachibadwidwe imapatsa wopanga chidaliro chowonjezereka pakuchita ndi chitetezo cha chipangizocho, chifukwa chimatsimikizira kuti zimagwiritsa ntchito zipangizo zamakono.
Izi sizabwino nthawi zonse - ndipo kuchuluka kwa makamera ochokera ku Aliexpress omwe amagwira ntchito pogwiritsa ntchito ma protocol "otayikira" komanso otseguka, "kuwonetsa" kuchuluka kwa anthu padziko lonse lapansi, ndi umboni woonekeratu wa izi. Ndi opanga monga Dahua Technology, omwe angakwanitse kuyesa machitidwe a chitetezo kwa nthawi yaitali, zinthu ndi zosiyana.
Protocol yachilengedwe ya IP kamera imalola kuti pakhale kuphatikizika komwe sikungatheke ndi ONVIF. Mwachitsanzo, mukalumikiza kamera yogwirizana ndi ONVIF ku NVR, muyenera kupeza chipangizocho, kuwonjezera, ndikuyesa ntchitoyo mu nthawi yeniyeni. Ngati kamera "ikulumikizana" pogwiritsa ntchito njira yachibadwidwe, ndiye kuti imadziwika ndikulumikizidwa ndi netiweki yokha.
Nthawi zina mukamagwiritsa ntchito chojambulira chokhala ndi kamera ya chipani chachitatu, mutha kuwona kuwonongeka kwa chithunzi. Mukamagwiritsa ntchito ma protocol amtundu wa zida zochokera kwa wopanga yemweyo, vuto ili, kwenikweni, silibwera ngakhale potumiza chizindikiro pa chingwe cha mpaka 800 metres (ndi ukadaulo Wowonjezera pa Ethernet).
Tekinoloje iyi idapangidwa ndikuyambitsidwa ndi Dahua Technology. Ukadaulo wa ePoE (Power over Ethernet) umagonjetsa malire a Efaneti achikhalidwe ndi POE (onse ochepera mamita 100 pakati pa madoko a netiweki) ndikuchotsa kufunikira kwa zida za PoE, ma Ethernet extenders, kapena ma switch owonjezera a netiweki.
Pogwiritsa ntchito ma encoding modulation ya 2D-PAM3, ukadaulo watsopano umapereka mphamvu, makanema, zomvera ndi zowongolera pamtunda wautali: pa 800 metres pa 10 Mbps kapena 300 metres pa 100 Mbps kudzera pa Cat5 kapena chingwe coaxial. Dahua ePoE ndi njira yosinthika komanso yodalirika yowunikira makanema ndipo imakupatsani mwayi wosunga pakuyika ndi ma waya.
Kuphatikiza ndi Dahua Technology
Mu 2014, Ivideon adayamba kugwirizana ndi kampaniyo , omwe ndi amodzi mwa opanga zida zamakanema padziko lonse lapansi, gawo lachiwiri lalikulu kwambiri pamsika wapadziko lonse lapansi wachitetezo. Pakali pano Dahua malo achiwiri pamndandanda wamakampani omwe ali ndi malonda akulu a&s Security 50.
Kugwirizana kwapafupi kwamakampani athu kwapangitsa kuti zitheke kukhazikitsa kuphatikizika kwa nsanja zambiri za zida, kuphatikiza masauzande masauzande amakamera a netiweki ndi zojambulira makanema.
Mu 2017, tidapanga yankho lomwe limakupatsani mwayi wolumikiza makamera ofananira komanso otanthauzira apamwamba pamtambo pogwiritsa ntchito
Tinathanso kupereka makina osavuta olumikiza nambala iliyonse ya makamera a Dahua kumtambo, mosasamala kanthu za malo awo, popanda kugwiritsa ntchito ma DVR, ma PC kapena mapulogalamu owonjezera.
Mu 2019, tidakhala ogwirizana nawo mu DIPP () - pulogalamu ya mgwirizano waukadaulo womwe umalimbana ndi chitukuko chophatikizana cha mayankho ophatikizika ophatikizika, kuphatikiza mayankho owunikira mavidiyo. DIPP imapereka mapangidwe apamwamba ndi chithandizo chaukadaulo pazolumikizana.
Thandizo la Dahua pazigawo zonse zopanga zinthu zatsopano zidatilola kuti tizilumikizana ndi ma protocol achilengedwe m'mayankho osiyanasiyana. Chimodzi mwazinthu zosangalatsa kwambiri za chaka chatha ndi , zomwe tinatha kukwaniritsa kugwirizanitsa ndi makamera a Dahua pamlingo wa chipangizo chawo "chobadwa".
Kodi βmlathoβ ukupita kuti?
Bridge ndi chida chofanana ndi rauta yaying'ono ya Wi-Fi. Bokosi ili limakupatsani mwayi wolumikiza makamera 16 amtundu uliwonse kumtambo wa Ivideon. Izi zikutanthauza kuti ogwiritsa ntchito machitidwe am'deralo amapeza mwayi wopita kumtambo popanda kusintha zida zoyikidwa. Mutha kuwonjezera makamera a analogi pamtambo kudzera pa chojambulira makanema cholumikizidwa ku Ivideon Bridge.
Mtengo wa chipangizocho lero ndi ma ruble 6. Pankhani ya chiΕ΅erengero cha mtengo / kanjira, Bridge yakhala njira yopindulitsa kwambiri yolumikizira mtambo wa Ivideon: njira imodzi yokhala ndi Bridge yokhala ndi zolipira zosungira zakale kuchokera ku Ivideon idzagula ma ruble 000. Poyerekeza: pogula kamera yokhala ndi mtambo, mtengo wa njira imodzi udzakhala ma ruble 375.
Ivideon Bridge si DVR ina, koma pulagi-ndi-sewero chipangizo kuti kwambiri kufewetsa kasamalidwe kutali kudzera mtambo.
Chimodzi mwazosangalatsa za "mlatho" ndikuthandizira kwathunthu kwa protocol yaku Dahua. Zotsatira zake, Bridge yakhala yolemeretsedwa ndi zinthu zomwe zimakhudza mwachindunji magwiridwe antchito amawu owonera makanema.
Zachilengedwe za Bridge ndi nsanja
Kujambulitsa deta yam'deralo
Njira yogwiritsira ntchito Edge Storage ikupezeka pamakamera onse a Dahua ndi ma DVR olumikizidwa kudzera pa Bridge pogwiritsa ntchito protocol yakomweko. Edge imakupatsani mwayi wojambulira kanema mwachindunji ku memori khadi yanu yamkati kapena NAS. Edge Storage imapereka zida zojambulira zotsatirazi:
- kupulumutsa maukonde ndi zosungira;
- kugawikana kwathunthu kwa kusungirako deta;
- kukhathamiritsa kugwiritsa ntchito bandwidth;
- kupanga zosunga zobwezeretsera zakale ngati kugwirizana kwalephera;
- kusungirako pamtambo wamtambo: ndikokwanira kukhazikitsa pulani yamtengo wapatali - mwachitsanzo, mtengo wocheperako wapachaka wa makamera 8 mumtambo udzakhala 1 rubles / mwezi kapena 600 rubles / chaka.
Kupezeka kokha kudzera mu protocol yachibadwidwe, Edge mode ndi njira yojambulira yosakanizidwa yomwe, kumbali imodzi, imachepetsa kuopsa kwa bizinesi komwe kumakhudzana ndi kutayika kwadzidzidzi, ndipo kumbali ina, kumakupatsani mwayi wopulumutsa pamtengo wokwera wa magalimoto.
Kukhazikitsa OSD ndi backlight
Ivideon Bridge imapereka mwayi wokhazikitsa zokutira zolembera, tsiku ndi nthawi pachithunzi (Pa Screen Display, OSD).
Mukamakoka, zolemba ndi deti zimayika "mamatira" ku gridi yosawoneka. Gululi ndi losiyana pa kamera iliyonse, ndipo kutengera komwe chizindikirocho chili pachithunzichi, malo enieni a mawu okutidwawo akhoza kuwerengedwa mosiyana.
Mukathimitsa zowunjikana zolembedwa kapena deti, zokonda zake zimasungidwa, ndipo mukayatsa, zimabwezeretsedwa.
Zokonda zomwe zimapezeka pa kamera inayake zimatengera mtundu wake komanso mtundu wa firmware.
Magawo ogwirira ntchito a Motion detector
Dongosololi limakupatsani mwayi wosintha mwachangu magawo ogwiritsira ntchito chojambulira choyenda, kuphatikiza kukhazikitsa malo odziwikiratu.
Kusintha magawo amtundu wamavidiyo
Kusintha magawo amakanema ndi ma audio kumathandizira kuchepetsa katundu pa njira ya intaneti - mutha "kudula" zikhalidwe zingapo ndikusunga pamagalimoto.
Kupanga maikolofoni
Monga momwe zimakhalira ndi mavidiyo, makonda a maikolofoni amapereka mwayi wofikira kukhudzika komwe kumakupatsani mwayi wogwiritsa ntchito chipangizocho mkati mwa zipinda zaphokoso.
Pomaliza
Bridge ndi chipangizo chapadziko lonse lapansi chomwe chimakulolani kuti muzitha kulumikiza makamera mwaluso. Njirayi idzafunika ngati mukufuna kulumikiza chojambulira chakale kapena kamera kumtambo womwe sungathe kudziwidwa.
Chifukwa cha kusinthasintha kwa makonzedwe a Bridge Bridge, wogwiritsa ntchito amatha kuthana ndi zochitika mosavuta pamene adilesi ya IP, kulowa kwa kamera / mawu achinsinsi akusintha, kapena chipangizocho chisinthidwa. Posintha kamera, simudzataya zosungidwa zakale zomwe zidajambulidwa kale mumtambo komanso zolembetsa zomwe zalipidwa kale pautumiki.
Ndipo ngakhale Bridge imakulolani kuti mugwire ntchito ndi ONVIF ndi RTSP pamlingo waukatswiri, osatopetsa wogwiritsa ntchito ndi "nthawi yoyamba mumayendedwe a Boeing cockpit", "kubwerera" kwakukulu kuchokera pamakamera kumatha kumveka ndi kuphatikiza kozama, monga momwe kungathekere. zikuwoneka mu chitsanzo cha chithandizo cha Dahua Technology protocol.
