Yuav Qhia Li Cas Yog Koj Lub Koob Yees Duab Kev Ruaj Ntseg Sau Hauv 4K lossis 1080P

Ntau tus tswv tsev thiab cov tswv lag luam nruabkoob yees duab kev ruaj ntsegcia siab tias yuav siv lead ua-cov duab meej meej, tsuas yog nrhiav tau tom qab ntawd cov ntsiab lus tseem ceeb xws li lub ntsej muag lossis daim ntawv tso cai pom qhov muag plooj dhau qhov kev lees paub. Cov lus nug tseem ceeb yog qhov yooj yim: yog koj lub koob yees duab tiag tiagkaw tseghauv 4K lossis 1080P?

4K(Ultra HD)thiab1080P(Full HD) xa mus rau qhov kev daws teeb meem ntawm cov ntaub ntawv khaws tseg video, tsis yog saib nyob hauv koj lub xov tooj xwb. Cov ntaubntawv povthawj siv 4K tiag tiag yog 3840 × 2160 pixels. Cov ntaub ntawv 1080P siv 1920 × 1080 pixels. Paub qhov txawv-thiab txheeb xyuas nws- cuam tshuam ncaj qha seb koj cov duab thaij puas ua pov thawj siv tau.

4K vs 1080P Cov Ntsiab Lus: Tus lej Tiag Tiag

Kev daws teeb meem txhais tau tias pes tsawg pixels ua rau txhua tus duab video. Ntau pixels xa cov ntsiab lus ntau ntxiv thaum koj zoom hauv lossis tshuaj xyuas cov duab tom qab.

1080P, tseem hu ua Full HD, muab kwv yees li 2.07 lab pixels. Nws tau ua tus qauv txhim khu kev qha rau ntau xyoo hauv ntau qhov chaw nyob thiab kev lag luam me.4K(UHD) dhia mus txog 8.29 lab pixels - kwv yees li plaub npaug ntawm qhov nthuav dav.

Qhov kev sib txawv no tseem ceeb tshaj plaws thaum ua si. Lub koob yees duab 1080P tuaj yeem pom tus neeg taug kev hauv txoj kev tsheb kom pom tseeb ntawm qhov pom. Tab sis zoom nyeem daim ntawv tso cai 30 ko taw deb, thiab daim duab sai sai tig muag. Cov ntaub ntawv 4K tiag tiag ua rau cov npoo ntse txawm tias tom qab digital zoom.

Cov ntaub ntawv qhia qhov tseeb.Cov ntawv thov kev lag luam thiab cov ntawv nyob hauv app tuaj yeem ua rau yuam kev. Nco ntsoov xyuas qhov tseeb khaws tseg video.

Lub hauv paus no pab koj txav mus dhau qhov tshwj xeeb rau kev ua haujlwm tiag tiag.

4K thiab 1080P hauv tiag-Kev Siv Ntiaj Teb: Lub Zog thiab Kev Txwv

4Kci nyob rau hauv loj dua los yog siab - ib puag ncig kev nyab xeeb. Xav txog lub tsev khaws khoom thauj khoom thauj khoom lossis chaw nyob ntev. Ntawm 50+ ko taw, 4K footage feem ntau ntes tau daim ntawv tso cai nyeem tau lossis lub ntsej muag uas 1080P tig mus rau hauv cov duab tsis pom tseeb. Digital zoom ntawm 4K cov ntaub ntawv nquag khaws cov ntsiab lus siv tau qhov twg 1080P poob sib nrug.

1080Ptseem siv tau rau ntau lub sijhawm. Nws ua haujlwm zoo rau lub qhov rooj, qhov chaw nqaim, lossis chaw ua haujlwm me me uas lub koob yees duab zaum ze ntawm qhov kev txiav txim. Nws siv tsawg cia thiab bandwidth, ua rau nws yooj yim dua nyob rau hauv tsev tes hauj lwm los yog ntau - lub koob yees duab systems. Hauv qhov chaw nruj nrog lub teeb pom kev zoo, 1080P feem ntau xa txhua yam xav tau yam tsis muaj nqi ntxiv.

4Kcoj kev xav tau siab dua. Cov ntaub ntawv siv ntau zaus ntau dua li 1080P, nyob ntawm tus nqi qis, tus ncej tus nqi, thiab compression nyiamH.265. Kev saib tej thaj chaw deb yuav tsum muaj zog upload bandwidth. Tsis yog txhua qhov NVR lossis huab npaj ua haujlwm puv 4K smoothly.

Xaiv raws li koj xav tau. Ib lub koob yees duab npog qhov chaw nres tsheb dav tau txais txiaj ntsig los ntawm 4K. Ntau lub koob yees duab tsom rau cov ntsiab lus nkag feem ntau ua tau zoo hauv 1080P.

Kev cia thiab bandwidth qhov tseeb feem ntau txiav txim siab seb koj tau sau dab tsi hnub tom qab hnub.

Yuav ua li cas kom raug txheeb xyuas koj lub koob yees duab cov ntaub ntawv daws teeb meem

Tsis txhob cia siab rau lub app nyob saib. Ntau lub tshuab qhia qis dua - daws teeb meemsub kwjntawm cov khoom siv mobile rau kev ua si du thaum kaw qhov siab dua - zoolub ntsiab kwjhauv zos.

Download tau cov duab qub ua ntej.Rub ib clip los ntawm qhovSD daim npav, NVR, lossis huab cia rau koj lub computer. Txoj cai -nias cov ntaub ntawv thiab xyuas nws cov khoom, lossis qhib nws hauv amedia playeruas qhia cov ncauj lus kom ntxaws.

Saib tshwj xeeb rau thaj chaw daws teeb meem video . 3840 × 2160 lees paub4K. 1920 × 1080 txhais tau tias1080P. Ib yam dab tsi ntxiv -xws li 2560 × 1440 (2K) lossis 2304 × 1296- poob qis ntawm qhov tseeb 4K.

Txheeb xyuas cov kev teeb tsa thoob plaws tag nrho cov system.Qhib lub koob yees duab app lossis NVR interface. Paub meej cov ntaub ntawv tseem ceeb ntawm cov lus tshaj tawm daws teeb meem. Xyuas bitrate thiab ncej tus nqi ib yam nkaus. Ib cov ntaub ntawv technically 4K nrog tsawg tsawg bitrate tseem tuaj yeem ua rau poob siab.

Khiav qhov kev sim teb sai.Muab ib daim ntawv xeem los yog cov ntawv luam tawm ntawm qhov kev ncua deb thaum nruab hnub. Sau 10-20 vib nas this, rub tawm cov ntaub ntawv, thiab zoom hauv 200%. Rov ua dua thaum hmo ntuj. Qhov no qhia txog qhov sib txawv ntawm qhov ua tau zoo ntawm kev saib ua ntej thiab kaw.

Cov kauj ruam no tshem tawm kev kwv yees. Cov ntaub ntawv tau txais kev cawmdim yog qhov pov thawj nkaus xwb.

Vim li cas koj lub koob yees duab yuav txhawb nqa 4K Tab sis Sau hauv 1080P

Ntau lub koob yees duab tshaj tawm 4K muaj peev xwm tsis tau ua rau txo qis hauv kev xyaum.

Feem ntau ua rau muaj xws li NVR channel txwv uas yuam kom downgrading, huab npaj uas compress footage txiav, los yog tej chaw uas xaiv sub kwj rau kaw. Tsawg SD daim ntawv sau nrawm lossis tsis txaus network bandwidth tuaj yeem ua rau txo qis. Qee lub tshuab qhia "Ultra HD" nyob rau hauv saib thaum lub ntsiab kwj cov ntaub ntawv qis dua.

Main stream vs sub kwjpiav ntau qhov tsis meej pem. Cov kwj dej loj ua haujlwm siab - daws teeb meem hauv zos kaw. Lub sub kwj txhawb nqa tau zoo saib tej thaj chaw deb. Kev tshuaj xyuas tsuas yog lub xov tooj app feem ntau ua rau cov neeg siv xav tsis thoob rau hauv kev xav tias lub koob yees duab khaws cia qis dua qhov nws ua tau.

Saib xyuas txhua txheej: lub koob yees duab teeb tsa, NVR teeb tsa, thiab kev xaiv huab. Kev tsis sib haum xeeb ntawm txhua qhov chaw tuaj yeem tiv thaiv qhov tseeb 4K kaw.

Tshaj li kev daws teeb meem: Dab tsi cuam tshuam rau duab zoo

Kev daws teeb meem suav pixels, tab sis qhov zoo nyob ntawm ntau dua. A4Kcov ntaub ntawv tuaj yeem saib mos thaum hmo ntuj yog tias lub sensor, lens, lossis infrared illumination underperforms. Tsawg bitrate, txo suab nrov, los yog lo ntsiab muag qias neeg kuj degrade cov txiaj ntsig txawm tias tus lej daws teeb meem raug.

Hmo pom kevmuab piv txwv meej. Muaj zog infrared LEDs thiab lub sensor zoo feem ntau tseem ceeb dua li kev daws teeb meem ib leeg. Lub koob yees duab zoo -engineered 1080P tuaj yeem ua tau zoo tshaj 4K qauv hauv lub teeb qis.

Ib txwm ntsuas cov duab tag nrho- daws teeb meem ntxiv rau kev txhawb nqa kho vajtse thiab kev teeb tsa kom raug.

Daim ntawv teev npe ceev thiab cov kauj ruam tom ntej

Siv daim ntawv txheeb xyuas no txhawm rau txheeb xyuas koj qhov teeb tsa sai:

• Download thawj cov ntaub ntawv video (tsis yog saib ua ntej xwb)

FAQ

Q1: Kuv puas tuaj yeem ntseeg qhov kev daws teeb meem hauv kuv lub mobile app?

Tsis yog. Mobile apps feem ntau tso saib qhov qis dua - daws teeb meem sub kwj rau kev ua si du. Nco ntsoov rub tawm cov ntaub ntawv video qub los ntawm SD daim npav lossis NVR thiab tshawb xyuas nws cov khoom tiag kom paub meej tias nws puas yog kaw hauv 4K (3840 × 2160) lossis 1080P (1920 × 1080).

Q2: Kuv lub koob yees duab tau tshaj tawm raws li 4K tab sis cov duab pom qhov muag plooj thaum hmo ntuj. Puas yog nws kaw hauv 1080P?

Tsis tas li. Hmo pom kev zoo nyob ntawm qhov ntsuas qhov loj me, lub lens zoo, infrared LEDs, thiab cov duab ua dua li kev daws teeb meem ib leeg. Lub koob yees duab 1080P zoo tuaj yeem ua haujlwm tsis zoo rau 4K qauv hauv lub teeb qis. Tshawb xyuas cov ntaub ntawv daws teeb meem ua ntej, tom qab ntawd ntsuas lwm yam khoom kho vajtse.

Q3: Ntau npaum li cas cov ntaub ntawv khaws cia 4K xav tau piv rau 1080P?

4K feem ntau xav tau ob peb zaug ntau dua kev cia siab dua 1080P, tab sis qhov sib txawv ntawm qhov sib txawv nrog bitrate, ncej tus nqi, codec (H.264 vs H.265), thiab hom kaw. Tsab ntawv tsa suab- tshwm sim los yog tshwm sim-raws li kev kaw cia txo qis kev xav tau khaws cia piv rau kev kaw cia tas mus li.

Q4: Puas yog qhov kev daws teeb meem siab dua ib txwm txhais tau tias cov duab zoo dua?

Kev daws teeb meem txiav txim siab pixel suav, tab sis tag nrho cov duab zoo kuj nyob ntawm bitrate, lens kev ua tau zoo, ua kom pom tseeb, thiab teeb tsa. Cov ntaub ntawv 4K technically nrog qis qis heev yuav zoo li phem dua li qhov zoo - optimized 1080P kaw.

Q5: Yog tias kuv lub koob yees duab tsuas yog sau hauv 1080P, kuv puas yuav tsum tau hloov mus rau 4K?

Nws nyob ntawm koj qhov xwm txheej . 1080P feem ntau txaus rau ze - thaj chaw xws li nkag, hauv tsev, lossis chav me. Hloov kho mus rau qhov tseeb 4K rau kev tsav tsheb ntev, chaw nres tsheb loj, warehouses, lossis cov xwm txheej uas koj nquag xav kom zoom rau kev txheeb xyuas lossis pov thawj.
