Nyob rau hauv thaum ntxov 2000s, ib tug nyob ntsiag to kiv puag ncig tshwm sim nyob rau hauv lub imaging kev lag luam: lub community launch txog thawj zoom thaiv koob yees duab. Cov qauv kev sib xyaw ua ke no tsis yog tsuas yog ntxiv cov khoom lag luam tshiab rau hauv kev ua lag luam- lawv tau hloov kho li cas cov phiaj xwm video tau tsim, rhuav tshem cov pwm ntawm cov kev daws teeb meem ib txwm muaj nrog lawv cov PCBs, sensors, thiab lo ntsiab muag. Rau cov engineers thiab cov neeg tsim khoom lag luam thaum lub sijhawm, qhov kev xav tau tam sim ntawd: ceev autofocus thiab optical zoom peev xwm ntim rau hauv me me hneev taw, qhib qhov muaj peev xwm rau kos duab rau hauv ntau hom kev siv uas yav dhau los tau txwv los ntawm kev teeb tsa lub koob yees duab bulkier.
Raws li ib tug neeg uas tau pom qhov kev hloov pauv ntawm kev lag luam duab thev naus laus zis hauv ob xyoo dhau los, kuv tau pom zoom thaiv cov koob yees duab hloov pauv los ntawm kev daws teeb meem rau lub hauv paus ntawm kev kos duab kos duab. Hauv daim ntawv no, kuv yuav piav qhia txog lawv txoj kev taug kev-los ntawm lawv cov keeb kwm txo qis hauv cov neeg siv khoom siv hluav taws xob mus rau lawv cov xwm txheej tam sim no raws li cov neeg ua haujlwm ntawm cov ntawv thov kev lag luam-thiab muab kev nkag siab txog qhov twg cov cuab yeej no yuav mus tom ntej. Dab tsi ua rau Zoom Block cov koob yees duab sawv tawm yog lawv qhov sib xyaw ua ke ntawm kev yoog raws thiab tus nqi- kev ua tau zoo, kev sib xyaw ua ke uas tau ua rau lawv tseem ceeb rau suav tsis txheeb hauv kev lag luam kos duab ua haujlwm.
Keeb Kwm: Hla -Pollination of Consumer and Security Needs
Nws yog ib qho yooj yim uas yuav saib tsis tau qhov zoom thaiv cov koob yees duab tam sim no yog ib qho tseem ceeb rau kwv yees li 20 xyoo -ib qho lus tim khawv rau lawv cov txiaj ntsig. Lawv zaj dab neeg pib tsis yog nyob rau hauv industrial labs, tab sis nyob rau hauv cov neeg siv khoom handheld camcorder lag luam ntawm lig 1990s thiab thaum ntxov 2000s. Rov qab thaum ntawd, cov neeg siv khoom siv lub koob yees duab Japanese tau caij nthwv dej ntawm kev xav tau los ntawm cov neeg siv kev txaus siab nrog kev zoom zoom: lub peev xwm zoom rau ntawm qhov chaw yam tsis muaj kev cuam tshuam cov duab zoo yog qhov kev ua si- hloov pauv rau cov yeeb yaj kiab hauv tsev thiab kev ua yeeb yaj kiab amateur. Qhov kev vam meej ntawm cov neeg siv khoom no tsis yog tus neeg tsav tsheb cov nyiaj tau los xwb- nws tau tso cov txheej txheem thev naus laus zis rau qhov uas yuav dhau los ua lub koob yees duab zoom thaiv.
Nyob ib ncig ntawm tib lub sijhawm, qhov kev sib tw sib luag tau nthuav tawm hauv lub koob yees duab kev ruaj ntseg sector. Cov neeg tsim khoom siv lub koob yees duab kev ruaj ntseg Japanese tau sib cav nrog qhov kev mob tshwm sim: cov txheej txheem kev daws teeb meem ntawm kev sib txuas lub thawv lub koob yees duab nrog lub ntsej muag zoom (feem ntau nrog qhov nqaim focal ntev li ntawm 2.8-12mm) yog kim thiab cumbersome. Cov pab pawg txhim kho feem ntau yuav tsum tau nce ntaiv los kho qhov ntev ntawm lub ntsej muag kom ua tau raws li cov neeg siv khoom xav tau-ib lub sijhawm- siv, ua haujlwm- cov txheej txheem hnyav uas tawm hauv chav me me kom yooj yim. Kev lag luam tau quaj rau qhov me me, pheej yig dua, thiab ntau tus neeg siv- lwm txoj hauv kev nyiam.
Lub koob yees duab thaiv zoom tau yug los ntawm qhov kev sib koom ua ke ntawm cov kev xav tau no, ua tsaug rau kev txawj ntse ntawm ib txhais tes ntawm pem hauv ntej-xav engineers. Qhov kev tawg tuaj thaum ib pab neeg muaj lub tswv yim yooj yim tab sis ci ntsa iab: ua ke kev lag luam - qib sensor (zoo rau kev ua haujlwm qis- teeb pom kev zoo, xav tau kev ruaj ntseg tseem ceeb) nrog lub lens optical zoom, thiab lub tsev ob qho tib si nrog PCB nyob rau hauv lub rugged hlau chassis. Qhov kev koom ua ke no tshem tawm qhov xav tau ntawm cov khoom sib cais, txiav qhov loj me thiab tus nqi thaum txhim kho kev ntseeg tau.
Cov pioneer thaum ntxov hauv qhov chaw no suav nrog Sony thiab Hitachi, txawm hais tias lawv txoj hauv kev tau cuam tshuam txog lawv qhov kev ua tau zoo. Sony, nrog nws cov hauv paus tob hauv cov neeg siv khoom siv hluav taws xob, tsim cov thev naus laus zis hauv -tsev, siv nws cov kev txawj ntse hauv sensors thiab optics. Hitachi, lub sijhawm no, tau coj qhov zoo tshaj plaws - hauv- cov khoom siv hauv chav kawm, nrhiav cov khoom zoo - lo ntsiab muag zoo los ntawm cov neeg koom tes ntseeg siab xws li Tamron thiab Fujinon los ua ke nrog Sony cov khoom lag luam sensors. Cov kev sau npe nyuaj rau kev ua haujlwm qis- teeb pom kev zoo-ib qho tseem ceeb rau kev siv kev ruaj ntseg- tau ua haujlwm los ntawm DSP chips, cov ntsiab lus uas qhia txog cov qauv kev lag luam- qib pedigree.
Lwm qhov tseem ceeb ntawm qhov kev sib tw yog qhov kev coj ua ntawm kev tswj hwm. Rov qab thaum ntawd, VISCA thiab Pelco-D tau tshwm sim raws li cov qauv ntawm qhov tseeb, thiab lawv qhov cuam tshuam ntev tau hais ntau txog lawv txoj kev ntseeg siab-txawm niaj hnub no, yuav luag txhua lub koob yees duab zoom thaiv hauv khw tseem txhawb cov txheej txheem no. Thaum ntxov iterations kuj pom ib tug tseem ceeb leap nyob rau hauv focal ntev ntau yam, nthuav mus rau 4.0 ~ 88mm (ib tug 22x optical zoom), tso cai rau cov scene tswj uas yooj yim rau ob qho tib si installation thiab cov neeg siv kev. Rau cov chaw muag khoom lub koob yees duab kev ruaj ntseg, qhov no yog qhov muag muag uas lawv tsis siv sijhawm los hais txog: "Tsis muaj ladders xav tau" tau dhau los ua suab nrov nrov, vim tias cov koob yees duab zoom thaiv cov koob yees duab tau ua rau cov chaw taws teeb hloov kho ntawm autofocus thiab zoom- tshem tawm qhov xav tau ntawm phau ntawv ntawm -site tweaks.
Kev ruaj ntseg OEM lag luam tau ceev kom paub txog lub peev xwm. Cov tuam txhab pib sib koom ua ke VGA- daws teeb meem thaiv cov koob yees duab rau hauv PTZ domes, thiab kev thov tau tawg. Thaum lub sijhawm, PTZ kev ua lag luam tau tswj hwm los ntawm cov neeg tsim khoom zoo li Pelco, Bosch, thiab Axis, uas muag ntau txhiab units txhua xyoo. Tab sis raws li kev tsim khoom hloov mus rau Tuam Tshoj, Asian PTZ dome manufacturers sai sai tau coj - ib qho qauv uas tseem niaj hnub no, nrog rau feem ntau ntawm embedded zoom thaiv cov koob yees duab tseem tsim nyob rau hauv Suav teb. Qhov kev hloov pauv no tsis tsuas yog ua rau tus nqi qis xwb tab sis kuj tseem ua rau kev hloov pauv sai, ua rau cov cuab yeej siv tau rau ntau qhov kev lag luam.
Tam sim no: Los ntawm Kev Ruaj Ntseg Niche mus rau Industrial Workhorse
Ob xyoo dhau los, zoom thaiv cov koob yees duab tau hla lawv qhov kev ruaj ntseg qub- tsom rau niche, nthuav mus rau ze li txhua lub ces kaum ntawm kev lag luam kos duab. Dab tsi ua rau lawv cuam tshuam? Hauv kuv qhov kev paub dhau los, nws yog lawv cov cwj pwm tseem ceeb: kev ntseeg tau tshwj xeeb, ruaj khov, yoog raws, thiab kev sib koom ua ke tsis sib haum. Rau cov ntawv thov kev lag luam- qhov twg cov cuab yeej siv feem ntau ua haujlwm nyob rau hauv ib puag ncig hnyav thiab lub sijhawm poob qis yog kim heev- cov yam ntxwv no tsis yog - sib tham. Niaj hnub no lub zoom thaiv cov koob yees duab khaws cia cov ntaub ntawv compact tab sis ntim rau hauv ib chav suite ntawm cov yam ntxwv siab heev: siab - daws teeb meem lo ntsiab muag, ua - nyob rau hauv siab - rhiab heev sensors, thiab siab - ceev autofocus systems uas tuaj yeem ua raws li qhov xav tau ntawm kev lag luam ua haujlwm.
Cov evolution ntawm technical evolution nyob rau hauv ob peb xyoos dhau los no yog tshwj xeeb noteworthy. Thaum kuv saib cov qauv tshiab, kuv pom cov kev txhim kho tseem ceeb uas hais txog qhov tseeb -lub ntiaj teb muaj kev mob cov ntsiab lus: txuas ntxiv kho qhov muag zoom lo ntsiab muag nrog cov duab stabilization (tseem ceeb rau cov ntawv thov xws li mobile tshuaj xyuas neeg hlau), tshem tau IR txiav cov ntxaij lim dej (ua kom nruab hnub / hmo ntuj ua haujlwm), defogging peev xwm (rau cov duab hnyav ib puag ncig), thiab LVDS cov txiaj ntsig digital transmissions ntau dua). Sensor thev naus laus zis kuj tau los ntev heev -los ntawm 720p daws teeb meem ntawm cov qauv thaum ntxov mus rau 1080p, thiab thaum kawg mus rau 4K. Qhov kev dhia hauv kev daws teeb meem no tau qhib cov ntawv thov tshiab, los ntawm kev tshuaj xyuas kev tsim khoom kom raug mus rau qib siab - kev soj ntsuam xyuas hauv cov txheej txheem tseem ceeb.
Qhov ntawd tau hais tias, raws li kev lag luam sab hauv, Kuv tau pom tias qhov kev daws teeb meem zoo li tau nce mus txog qhov kev txwv rau feem ntau ntawm kev siv hauv kev lag luam. Thaum 4K ntau tshaj qhov txaus rau yuav luag tag nrho cov duab kos duab ua haujlwm, lub hom phiaj ntawm kev tsim kho tshiab tau hloov pauv -yog li- mus rau qis - lub teeb ua haujlwm. Hauv ntau qhov chaw muaj kev lag luam, los ntawm cov khw muag khoom tsis pom kev mus rau cov kav dej hauv av, qis - lub teeb rhiab heev tuaj yeem ua lossis tawg kev tshuaj xyuas. Qhov no yog qhov uas kuv pom qhov kev txhim kho nquag tshaj plaws niaj hnub no, thiab nws yog ib qho qauv uas yuav txhais tau rau theem tom ntej ntawm zoom thaiv lub koob yees duab evolution.
Yav tom ntej Outlook: Tsom ntsoov rau kev ua tau zoo, tsis yog kev daws teeb meem xwb
Yog li, dab tsi yav tom ntej tuav rau zoom thaiv cov koob yees duab? Raws li kuv cov kev soj ntsuam ntawm sensor thiab lens technology roadmap, kuv tsis xav tias yuav rov qab mus rau "kev daws teeb meem kev sib tw" ntawm kaum xyoo dhau los. Hloov chaw, ob peb xyoos tom ntej no yuav raug txhais los ntawm kev nce ntxiv tab sis muaj txiaj ntsig kev txhim kho hauv qis- teeb pom kev zoo- tau tsav los ntawm kev nce qib hauv sensor pixel tsim thiab lens txheej. Rau cov neeg siv kev lag luam, qhov no txhais tau hais tias cov duab zoo dua hauv cov teeb pom kev nyuaj nyuaj, txo qhov xav tau ntawm cov teeb pom kev zoo thiab nthuav dav ntau qhov chaw uas zoom thaiv cov koob yees duab tuaj yeem siv tau.
Tshaj li qis- lub teeb muaj peev xwm, Kuv cia siab tias yuav muaj kev koom ua ke ntxiv nrog IoT (IIoT) ecosystems. Yav tom ntej zoom thaiv cov koob yees duab yuav muaj peev xwm ua kom pom cov digital interfaces siab dua, ua kom muaj kev sib txuas tsis sib haum nrog cov cuab yeej siv cuab yeej cuab tam thiab huab platforms. Qhov no yuav tso cai rau kev txheeb xyuas cov duab tiag - sijhawm, kev saib xyuas kev kwv yees, thiab kev saib xyuas thaj chaw deb- muaj peev xwm ua kom muaj peev xwm ua tau tseem ceeb hauv cov chaw tsim khoom ntse thiab kev sib txuas.
Saib rov qab, txoj kev taug kev ntawm lub koob yees duab zoom thaiv yog ib qho piv txwv zoo ntawm cov neeg siv khoom siv thev naus laus zis tuaj yeem rov ua dua tshiab rau kev siv hauv kev lag luam, thiab yuav ua li cas daws qhov mob tshwj xeeb (cumbersome ruaj ntseg lub koob yees duab installation) tuaj yeem ua rau lub tshuab hloov pauv tag nrho kev lag luam. Raws li peb saib ua ntej, lawv cov txiaj ntsig zoo yuav nyob rau hauv lawv lub peev xwm los hloov kho cov kev xav tau hloov pauv ntawm cov neeg siv khoom lag luam-tseem tshuav kev cog lus, txhim khu kev qha, thiab tus nqi- siv tau thaum koom nrog cov yam ntxwv tseem ceeb tshaj plaws hauv kev siv tiag - ntiaj teb no. Rau cov kws tsim khoom thiab cov kws tsim khoom tsim khoom, lawv yuav txuas ntxiv mus ntxiv - los daws qhov teeb meem rau kev kos duab rau hauv cov khoom lag luam tiam tom ntej.
