Nyob rau xyoo tas los no, nrog rau kev nce qib ntawm kev loj hlob hauv nroog thiab kev paub txog kev ruaj ntseg hauv tsev ntawm cov neeg siv khoom, kev loj hlob ntawm kev lag luam kev ruaj ntseg ntawm cov neeg siv khoom tau nrawm dua. Muaj kev thov ntau ntxiv rau ntau yam khoom siv kev ruaj ntseg rau cov neeg siv khoom xws li lub koob yees duab kev ruaj ntseg hauv tsev, cov khoom siv saib xyuas tsiaj ntse, cov txheej txheem saib xyuas menyuam yaus, thiab lub qhov rooj xauv ntse. Ntau hom khoom, xws li lub koob yees duab nrog cov ntxaij vab tshaus, lub koob yees duab AOV fais fab tsawg, lub koob yees duab AI, thiab lub koob yees duab binocular / ntau lub lens, tab tom tshwm sim sai sai, txuas ntxiv tsav tsheb tshiab hauv kev lag luam kev ruaj ntseg.
Nrog rau kev hloov kho tshiab ntawm thev naus laus zis kev ruaj ntseg thiab kev xav tau ntawm cov neeg siv khoom uas hloov zuj zus, cov khoom siv uas muaj ntau lub lens tau dhau los ua qhov nyiam tshiab ntawm kev ua lag luam, tau txais kev saib xyuas ntxiv los ntawm kev ua lag luam thiab cov neeg siv khoom. Cov koob yees duab ib lub lens ib txwm muaj qhov tsis pom kev hauv lawv thaj chaw pom. Txhawm rau daws qhov teeb meem no thiab ua tiav lub kaum sab xis pom dav dua, cov tuam txhab tsim khoom tam sim no ntxiv ntau lub lens rau cov koob yees duab ntse, hloov mus rau kev tsim binocular / ntau lub lens los muab kev npog dav dua thiab txo cov qhov tsis pom kev saib xyuas. Tib lub sijhawm, cov koob yees duab binocular / ntau lub lens sib xyaw ua ke cov haujlwm uas yav dhau los xav tau ntau lub cuab yeej rau hauv ib yam khoom, txo cov nqi thiab txhim kho kev teeb tsa zoo. Qhov tseem ceeb tshaj plaws, kev tsim kho thiab kev hloov kho tshiab ntawm cov koob yees duab binocular / ntau lub lens sib haum nrog kev tsim kho tshiab sib txawv uas cov tuam txhab tsim khoom ruaj ntseg tab tom nrhiav hauv kev ua lag luam sib tw ntau ntxiv, coj cov cib fim tshiab rau kev loj hlob rau kev lag luam.
Cov yam ntxwv tam sim no ntawm cov koob yees duab ntawm kev ua lag luam hauv Suav teb:
• Nqe: Cov koob yees duab uas muaj nqi qis dua $38.00 suav txog li 50% ntawm kev lag luam, thaum cov hom lag luam loj tab tom tsom mus rau kev tsim cov khoom tshiab hauv tus nqi siab dua ntawm $40.00-$60.00.
• Pixels: Cov koob yees duab 4-megapixel yog cov khoom tseem ceeb, tab sis cov pixels feem ntau maj mam hloov ntawm 3MP thiab 4MP mus rau 5MP, nrog rau cov khoom 8MP tshwm sim ntau zuj zus.
• Ntau Yam: Cov khoom siv ntau lub koob yees duab thiab cov koob yees duab sab nraum zoov uas muaj lub dome tseem nrov, nrog lawv cov feem muag khoom tshaj 30% thiab 20%, raws li.
Tam sim no, cov hom koob yees duab binocular / multi-lens tseem ceeb hauv kev ua lag luam suav nrog plaub pawg hauv qab no:
• Kev Sib Koom Ua Duab thiab Kev Pom Kev Pom Kev Hmo Ntuj Tag Nrho: Siv ob lub sensors thiab ob lub lens los ntes xim thiab qhov kaj sib cais, cov duab tau sib koom ua ke tob kom tsim tau cov duab xim tag nrho thaum hmo ntuj yam tsis tas yuav siv teeb pom kev ntxiv.
• Kev Txuas Bullet-Dome: Qhov no muab cov yam ntxwv ntawm cov koob yees duab bullet thiab cov koob yees duab dome sib xyaw ua ke, muab ob qho tib si lub lens dav-lub kaum sab xis rau kev pom panoramic thiab lub lens telephoto rau kev pom ze ze. Nws muab cov txiaj ntsig xws li kev saib xyuas lub sijhawm tiag tiag, qhov chaw raug, kev ruaj ntseg zoo dua, kev ywj pheej muaj zog, thiab yooj yim rau kev teeb tsa. Cov koob yees duab txuas Bullet-dome txhawb nqa ob qho tib si kev saib xyuas static thiab dynamic, muab kev paub txog kev pom ob qho tib si thiab ua tiav kev ruaj ntseg niaj hnub.
• Hybrid Zoom: Cov thev naus laus zis no siv ob lossis ntau lub lens tsom teeb tsa hauv tib lub koob yees duab (piv txwv li, ib qho nrog qhov ntev me dua, zoo li 2.8mm, thiab lwm qhov nrog qhov ntev loj dua, zoo li 12mm). Ua ke nrog cov algorithms zoom digital, nws tso cai rau kev zooming hauv thiab tawm yam tsis muaj kev poob pixel loj, piv rau kev zoom digital xwb. Nws muab kev zooming sai dua yam tsis muaj kev ncua sijhawm piv rau kev zoom mechanical.
• Kev Sib Txuas Panoramic: Cov khoom no ua haujlwm zoo ib yam li cov kev daws teeb meem kev sib txuas ntawm lub koob yees duab saib xyuas. Lawv siv ob lossis ntau lub sensor thiab lens hauv ib lub tsev, nrog rau kev sib tshooj me ntsis hauv txhua lub sensor daim duab. Tom qab sib dhos, lawv muab qhov pom panoramic zoo nkauj, npog kwv yees li 180°.
Qhov tseem ceeb, kev loj hlob ntawm kev ua lag luam rau cov koob yees duab binocular thiab ntau lub lens tau tseem ceeb heev, nrog rau lawv qhov kev ua lag luam tau dhau los ua qhov tseem ceeb. Zuag qhia tag nrho, raws li AI, kev ruaj ntseg, thiab lwm yam thev naus laus zis txuas ntxiv hloov pauv thiab raws li kev thov ua lag luam hloov pauv, cov koob yees duab binocular / ntau lub lens saib xyuas tau npaj los ua qhov tseem ceeb hauv kev ua lag luam IPC (Internet Protocol Camera) ntawm cov neeg siv khoom. Kev loj hlob tas mus li ntawm kev ua lag luam no yog qhov sib txawv tsis lees paub.
