Dab tsi yog lub koob yees duab PTZ?
PTZ lub koob yees duab yog ib qho kev ruaj ntseg system los txhawb ib tug tag nrho ntau (up thiab down, sab laug thiab txoj cai) mobile thiab zoom lens zoom, zoom tswj lub koob yees duab.
PTZ no yog ib qho kev sib txig rau Pan / Tilt / Zoom. PTZ lub koob yees duab tso cai rau koj saib xyuas qhov "pom dav" ntawm 360 degree los yog 180 degree lub teb lub voj voog thiab lub siab ceev dome lub koob yees duab tuaj yeem ua tig mus rau hauv thaj tsam ntawm kev txaus siab los ntawm kev saib lub panoramic saib ntawm thaj tsam ntawm kev txaus siab. , Thiab ua tiav qhov lawv tsis muaj peev xwm, uas tseem muaj lub koob yees duab panoramic "saib dav" zoo thiab cov koob yees duab "high-speed dome" saib "zoo meej".
Yav tas los, megapixel koob yees duab raug txwv rau kev sib tw ua haujlwm, tsuas yog nyob rau hauv kev daws teeb meem megapixel, tsuas yog M-JPEG encoding hom. Yog li, PTZ koob yees duab cov neeg siv leej twg xaiv megapixel daws teeb meem, txais 15Mbps los yog ntau dua bandwidth thiab siab dua nqi; txawm yog yuav txo tau cov koob yees duab megapixel ncej npaum li ib lub koob yees duab cov koob yees duab siv. Yog li, txawm hais tias lub koob yees duab megapixel nyob rau hauv kev ua lag luam, tab sis qhov kev daws teeb meem loj thiab kev sib txawv ntawm cov qhab nia feem ntau yog qhov hauv paus ua rau nws tsis muaj peev xwm kis tau.
Tab sis qhov teeb meem saum toj no hauv 2008 tau raug hloov kiag li. Nyob rau hauv 2008, txoj kev lag luam pib tsim lub ntiaj teb thawj zaug raws H.264 encoding ntawm lub tswv yim zoo siab txhais lub koob yees duab, vim muaj kev sib kho zoo ntawm kev daws teeb meem, PTZ lub koob yees duab siab npaum li cas thiab kev sib tw bandwidth, ua network xyuas tiag rau hauv cov tswv yim ua lub ntsiab lus tseem ceeb Lub sij hawm tom qab, domestic thiab txawv teb chaws cov kws ua lag luam pib tawm ntau lub ntsiab lus ntawm kev ruaj ntseg thooj txhij thiab taag hemisphere, thiab H.264-high-definition network lub koob yees duab. Mus txog rau tam sim no, tsis muaj teeb meem nyob qhov twg, peb tham txog HD, muag HD, ntau dua thiab ntau cov neeg siv kuj siv high-definition. HD network xyuas tau nkag mus rau lub sijhawm nyuab siab. Network PTZ lub koob yees duab yog qhov tseem ceeb tshaj plaws kev txhim kho kev loj hlob yog lub ntsiab lus siab!
