Makina oteteza makamera a IP abweretsa zabwino zambiri pamsika kuyambira pomwe adakhazikitsidwa, koma chitukuko sichinakhale bwino nthawi zonse. Kwa zaka zambiri, opanga mawonedwe amakanema akhala akulimbana ndi zovuta zokhudzana ndi zida.
Pulogalamu imodzi yapadziko lonse lapansi idafunikira kuti athetse vutoli pophatikiza zinthu zopangidwa ndi opanga osiyanasiyana mkati mwa dongosolo limodzi, kuphatikiza makamera othamanga kwambiri a PTZ, zida zokhala ndi ma lens ang'onoang'ono ndi zoom, ma multiplexers, ndi makanema ojambula pa intaneti.
Komabe, ma protocol akomwe ochokera kwa opanga zida zamakanema amakhalabe othandiza masiku ano. Ngakhale mu chipangizo cha Ivideon Bridge, chomwe chimathandizira kulumikizidwa kwamtambo pafupifupi 98% yamitundu yamakamera, timapereka luso lapadera pogwira ntchito ndi ma protocol akomwe.
Tifotokoza chifukwa chake izi zidachitika komanso maubwino otani omwe amaperekedwa pogwiritsa ntchito kuphatikiza ndi Dahua Technology mwachitsanzo.
Zogwirizana muyezo
M'mbiri yakale, kupanga njira yothandiza kwambiri yomwe imagwirizanitsa njira zabwino kwambiri kuchokera kwa ogulitsa angapo zafuna ntchito yaikulu yophatikizana.
Pofuna kuthana ndi kusagwirizana kwa zida, muyezo wa Open Network Video Interface Forum unapangidwa mu 2008. ONVIF inalola okonza ndi oyika kuti achepetse nthawi yoyika zigawo zonse za kanema.
Ophatikiza madongosolo ndi ogwiritsa ntchito omaliza atha kusunga ndalama ndi ONVIF posankha mwaufulu wopanga aliyense pokulitsa dongosolo kapena kusintha pang'ono zigawo zake.
Ngakhale kuthandizidwa ndi ONVIF kuchokera kwa opanga zida zamakanema otsogola, pafupifupi kampani iliyonse yayikulu imagwiritsabe ntchito njira yakeyake, yochokera ku kamera ya wopanga aliyense ndi DVR.
Zida zambiri za Dahua Tech zimathandizira onse a ONVIF ndi eni ake a Dahua Private Protocol, omwe Dahua amagwiritsa ntchito kupanga zida zachitetezo chokwanira kutengera zida zake.
Native protocols
Kupanda malire aliwonse ndi mwayi wa chitukuko mbadwa. Wopangayo amagogomezera zinthu zomwe amawona kuti ndizofunikira pazantchito zake zomangidwira, kuthandizira mphamvu zonse za zida zake.
Chotsatira chake, ndondomeko yachibadwidwe imapatsa wopanga chidaliro chochuluka pakuchita ndi chitetezo cha chipangizocho, chifukwa chimatsimikizira kuti zimagwiritsa ntchito zipangizo zamakono.
Izi sizikhala zabwino nthawi zonse-ndipo kuchuluka kwa makamera ochokera ku Aliexpress, omwe akugwira ntchito pazolakwika komanso zotseguka zomwe zimawonetsa kuchuluka kwa anthu padziko lonse lapansi, ndi umboni woonekeratu wa izi. Ndi opanga monga Dahua Technology, omwe angakwanitse kuyesa chitetezo chokwanira, zinthu ndi zosiyana.
Protocol yachilengedwe ya kamera ya IP imathandizira kuti mulingo wophatikizika ukhale wosatheka ndi ONVIF. Mwachitsanzo, polumikiza kamera yogwirizana ndi ONVIF ku chojambulira makanema apaintaneti, muyenera kupeza chipangizocho, kuwonjezera, ndiyeno kuyesa ntchito yake munthawi yeniyeni. Ngati kamera imalumikizana pogwiritsa ntchito protocol yachilengedwe, kupezeka kwake ndi kulumikizana ndi netiweki kumachitika zokha.
Nthawi zina, mukamagwiritsa ntchito dashcam yokhala ndi kamera yachitatu, mutha kuwona kuwonongeka kwa chithunzi. Mukamagwiritsa ntchito ma protocol ochokera kuzipangizo zochokera kwa wopanga yemweyo, vutoli silichitika kawirikawiri, ngakhale potumiza chizindikiro pa chingwe chofikira mamita 800 (pogwiritsa ntchito ukadaulo wa Extended Power over Ethernet).
Tekinoloje iyi idapangidwa ndikuyambitsidwa ndi Dahua Technology. ePoE (Power over Ethernet) imagonjetsa malire a Efaneti yachikhalidwe ndi POE (zonse zimangokhala mamita 100 pakati pa madoko a netiweki) ndikuchotsa kufunikira kwa zida za PoE, zowonjezera za Ethernet, kapena ma switch owonjezera a netiweki.
Pogwiritsa ntchito 2D-PAM3 coding modulation, teknoloji yatsopanoyi imapangitsa kuti magetsi, mavidiyo, ma audio, ndi kuwongolera kufalikira kwa chizindikiro pamtunda wautali: kupitirira mamita 800 pa 10 Mbps kapena mamita 300 pa 100 Mbps kudzera pa Cat5 kapena chingwe coaxial. Dahua's ePoE imapereka mawonekedwe osinthika komanso odalirika owonera makanema ndikuchepetsa mtengo woyika ndi waya.
Kuphatikiza ndi Dahua Technology
Mu 2014, Ivideon adayamba kugwirizana ndi kampaniyo , yemwe ndi m'modzi mwa otsogola opanga zida zamakanema padziko lonse lapansi, gawo lachiwiri lalikulu kwambiri pamsika wachitetezo padziko lonse lapansi. Pakali pano, Dahua malo achiwiri pamndandanda wamakampani omwe ali ndi malonda akulu a&s Security 50.
Kugwirizana kwapakati pakati pamakampani athu kwathandizira kuphatikiza mapulatifomu angapo a hardware, kuphatikiza masauzande a makamera a netiweki ndi makanema ojambula.
Mu 2017, tidapanga yankho lomwe limakupatsani mwayi wolumikiza makamera ofananira komanso otanthauzira apamwamba pamtambo pogwiritsa ntchito
Tinathanso kupereka njira yosavuta yolumikizira nambala iliyonse ya makamera a Dahua kumtambo, mosasamala kanthu za malo awo, popanda kufunikira kwa zojambulira mavidiyo, ma PC, kapena mapulogalamu owonjezera.
Mu 2019, tidakhala ogwirizana nawo mu DIPP () ndi pulojekiti yothandizana ndi ukadaulo yomwe cholinga chake ndi kupanga pamodzi mayankho ophatikizika, kuphatikiza kusanthula kwamavidiyo. DIPP imapereka mapangidwe apamwamba ndi chithandizo chaukadaulo pazolumikizana.
Thandizo la Dahua m'magawo onse opanga zinthu zatsopano zidatilola kuphatikizira njira zachikhalidwe m'njira zosiyanasiyana. Chimodzi mwazinthu zosangalatsa kwambiri za chaka chathachi ndi , zomwe tinatha kukwaniritsa kugwirizanitsa ndi makamera a Dahua pamlingo wa chipangizo chawo "chobadwa".
Kodi "mlatho" ukupita kuti?
Bridge ndi chida chofanana ndi rauta yaying'ono ya Wi-Fi. Bokosi laling'onoli limakupatsani mwayi wolumikiza makamera a 16 kumtambo wa Ivideon. Izi zikutanthauza kuti ogwiritsa ntchito makina apanyumba amatha kupeza ntchito yamtambo popanda kusintha zida zawo zomwe zilipo. Ngakhale makamera a analogi amatha kuwonjezeredwa pamtambo kudzera pa chojambulira chamavidiyo cholumikizidwa ku Ivideon Bridge.
Chipangizocho chimawononga ma ruble 6,000. Pankhani ya mtengo pa tchanelo, Bridge yakhala njira yotsika mtengo kwambiri yolumikizira mtambo wa Ivideon: njira imodzi yokhala ndi Bridge ndi zosungira zakale za Ivideon zimawononga ma ruble 375. Poyerekeza, kugula kamera yokhala ndi mwayi wamtambo kumawononga ma ruble 5,500 panjira.
Ivideon Bridge si DVR ina chabe, koma pulagi-ndi-sewero chipangizo chimene kwambiri kufewetsa kasamalidwe kutali kudzera mtambo.
Chimodzi mwazinthu zosangalatsa za mlathowu ndikuthandizira kwake kwathunthu kwa protocol yaku Dahua. Zotsatira zake, Bridge Bridge idalemeretsedwa ndi zinthu zomwe zimakhudza mwachindunji magwiridwe antchito amawu owunikira makanema.
