PTZ kamera - chii ichocho?

PTZ makamera ibazi recompact video surveillance devices. Vagadziri vemidziyo iyi vakagadzirisa kuchengetedzwa kwekamberi makamera kusvika kune imwe nhanho pamusana pemagetsi avo anonyatsogadzirisa, uye mune dzimwe nguvawo robotic inyanzvi yekudzivirira. Mune zvimwe, magetsi akafanana akashandiswa muzvizvarwa zvekutanga zvevideo surveillance systems, asi mhinduro dzemazuva ano dzinoparadzaniswa zvakajeka muzviverengero zvakawanda, izvo zvinosimbiswa nemuenzaniso we PTZ kamera. Izvi zvinorevei mukuita? Chokutanga pane zvose, ndiyo mikana yakawanda yekudzora maikiramu emakera, uye mumamiriro ekure. Mukuwedzera, vadziri vezvikwata zveTPZ vanonyatsoteerera maitiro ekutanga ekupfura, vachikubvumira kuwana mhando dzakakwirira dzemifananidzo apo uchichengetedza kukura kwakaderera kwekamera pachako.

General information pamusoro pemakamera eTZZ

Uyu haisi yemikiramu kamera, mutsauko mukuru wekuvepo kwekubatanidzwa kwemagetsi-mechanical drive. Uyezve, matrix pachayo, iyo inoita kuti kugadziriswa kwevhidhiyo ishandiswe, inonyatsoenderana nemamiriro ekugadzirwa kwekamberi makamera kuitira kuongororwa kwevhidhiyo. Zviratidzo zvakagadzirirwa nekutya ne robotic control principle, iyo, nenzira, inogona kuita sechikamu chakaparadzaniswa-chimwe chikamu chegadziriro yakakwana. Zvisinei, mazuva ano mapurisa emhando iyi yakasiyana uye iri mukati. Kugadzirwa kwemaziso, kunyanya, kunoita kuti iwe uchinje maonero ekuona, ayo anotora PTZ kamera. Ndezvipi izvi maererano nemutengi? Muchidimbu, izvi zvinoreva kushandiswa kwakasiyana-siyana kwetara nekunonoka kwechiedza uye kuwedzera kwechinhu chinotarisirwa. Zviratidzo zvekudzora motokari yekugadzirisa uye mukati me sensor zvinogona kubva kubva kure, uye zvinogona kugadzirwa nevatongi vanotaura nekombiyuta. Izvi zvinoreva, kuburikidza ne-software, mushumiri anogona kugadzirisa kamera kuti iite zvakakwana kushanda.

Zvinonyanya kukoshesa kamera

Nhamba yepikisiki ndiyo chiratidzo chikuru chehutano hwebasa remarudzi ose emakamera akadaro. Shanduro dzakanakisisa dzakapiwa matrices pa 0.3 MP, nepamusoro-tech versions - ne modules pa 5 MP. Nhamba yeefaira dzakanyorwa zvakagadzirwa mumasero matanhatu -30. Zvechokwadi, mukuongorora kunaka kwechifananidzo hakugoni kuita kunze kwekugadzirisa kwechigadzirwa PTZ - HD-kamera, somuenzaniso, tsigira nechivimbo fomu 1920x1080. Panguva imwecheteyo, chivako cheVGA chakaitika panguva ye640x480 chinoramba chakakosha. Mukuchengetedzwa kwekuchengetedza, kushandiswa kwema modules akadaro kazhinji kwakarurama. Asi kana zviri pamusoro apa zvichitsanangurwa zvizere zvakakwana zvakagadzirirwa muhutano hwemhando dzekambani dzeCCTV makamera, zvino mukukurumidza kwekushanduka uye kuwedzera mukutarisa PTZ kune zvakakosha. Nokudaro, kukura kwe optical kunogona kuva 36-peta, uye kuvhenekera kwedijitini 18-iko. Kana iri yekukurumidza kwekuzungunuka, mumazuva ano maitiro anosvika 400 ° / s. Uyewo, kufambira mberi kwakagadziridzwa kwakagadzirwa ne 3D inonzi technology technology.

Minda yekushandiswa kweTPZ

Nyanzvi dzinoziva nzvimbo mbiri umo maitiro ekushanda emakamera akadaro anonyanya kuziviswa. Izvi ndezvekuchengetedzwa kwezvigadziro maitiro uye kubudiswa kwevhidhiyo mumakamuri emagungano. Muzviitiko zvose izvi, vashanduri vanoziva kushanduka kwemichina yacho maererano nehutungamiri uye zvinenge zvisingagoneki zvigadziriswa zvekugadzirwa kwezvigadzirwa zvemichina. Pano zvakakosha kucherechedza midziyo isina kushandiswa inoshandiswa neTPZ yemazuva ano. Izvozvo zvinorevei mukushanda kwekushanda? Shanduro dzese dzisingabatsiri dzekutaurirana dzinoita kuti zvigadzirise kudiwa kwematare kuti ave nechokubatanidza nechokushandisa. Mukureva kushandura, iyi ndiyo yakanakisisa mhinduro, sezvo uyo anorwisa achange aine mukana muduku wekuona zviratidzo zvevhidhiyo yekutarisa system. Kusiyana naizvozvo, basa rekushanda re rotary camera mechanics richabvumira kuona zviri kuitika mukamuri ine nzvimbo inobatsira zvikuru.

Mitambo yevhidhiyo kamera yakagadzirwa

Vagadziri vanobudisa makamera emhando iyi mumhando dzakasiyana-siyana. Inonyanya kukosha ndeye PTZ kamera nenzira yehemisphere. Iyi shanduro inonzi Speed Speed uye ine kukanganisika kwakanyanya. Izvo zvakagadziriswa pachedu, zvichienderana nemagadzirirwo ayo emagetsi, inoderedza dambudziko revhu nekunyoro kunowira pasi peimba.

Imwe nzira - yakagadzirirwa, yakanyanya kufanana nemakamuri nenzira yehemisphere. Mienzaniso yakadaro inowanzove yakagadziriswa nemagetsi ane simba uye nzira dzokudzivirirwa pakurwisana nemhepo. Muzhinji, PTZ dome makamera yakagadzirwa nenzira yakadaro iyo yose inogadzirisa zvikamu zvekuzadza ine mikana yakawanda yekubatana zvakananga nemhepo. Izvi zvinonyanya kuoneka mumatambudziko emigwagwa yemigwagwa, iyo inokodzera kunyatsotarisirwa.

Zviratidzo zvemigwagwa yemugwagwa

Kuvhima kwekunze kwevhidhiyo maitiro ekudikanwa kunoda kutarisa zvimwe zvinhu zvinowedzera. Pakati pavo pane mavara ekutsigira kuwirirana kwekhamera uye mapurisa ekugadzirisa, sangano rekugonesa kwenyika uye kuchengetedzwa kwemidziyo inobva kune dzimwe nyika. Nezvekudzivirirwa, zvikwata zvinowanzogamuchira jekete yehutsi ine guruva uye kusungira mvura kusina mvura. Mimwe mienzaniso inowedzera kugoverwa neheater uye ventilation system, iyo inobvumira kutonhora kunotanga pamwero wakaipa uye kutema kwakanaka. Simba rinogona kupiwa zvakananga kana nebheteri. Nenzira, kushandiswa kwesimba risina kushandiswa kunobvumirwawo. Kunyange imwe iyo PTZ yakagadzirirwa kamera inokubvumira kuti uite maitiro ekushandura kune simba rekuchengetedza mukana wekusagadzikana kwemasimba emagetsi. Kukurukurirana, zvakare, kwakarongekawo zvakananga kuburikidza nekambo kana wireless teknolojia kuburikidza nehurukuro yemudhiyo.

Analog uye Digital Models

Mune mifananidzo yeAnalogog, rekodi yakagamuchirwa inongororwa nekugadziriswa ne digital digiti. Zvadaro nyaya yacho inotumirwa kumagetsi ekushandura, umo kutendeuka kunoitikazve, asi nenzira yakatarisa. Kukurukurirana kwekukurukurirana kwemidziyo yakadaro kunopiwa nea coaxial wires. Kuvhiringidzika kwevatungamiri vorudzi urwu kunosanganisira kugadziriswa kwakadzika, izvo zvisingakubvumiri kutarisira chimiro chepamusoro-soro kana kupfurwa pamakirwere akareba. Digital PTZ-CCTV makamera anopawo kutanga kugadzirisa zviratidzo mumushandisi, mushure mokunge mashoko acho anokwanisa kuparadzirwa pamusoro peTCP / IP protocol pane yakatanga kujekeswa. Kubudirira kukuru kwemajitiramu emagetsi ndeyechokwadi "mifananidzo" yepamusoro-soro, nokuti mumashoko ekukurukurirana nemichina yekugadzira, zvigadzirwa zveanalogog mune zvimwe zviitiko zvinogona kugadziriswa.

Camera control

Mukuwedzera pakagadzirisa zvigadziriro zvekupfura, kamera dze PTZ dzinopa hutano hwakawanda hwemagetsi huripo mukushanda kwekushanda kwekushandisa kwechokushandisa. Pakuisa khamera pane chimwe chinhu, musarudzo anogona kutarisa purogiramu mumazana ezvigadziriswa. Neimwe nzira, sarudzo yose yemamiriro ezvinhu inofungidzirwa, pakati payo iyo kukosha kwema angle, zoom zoom, nezvimwewo. Mimwe mienzaniso inokubvumira kuti iwe ugovera script yega yega yekutengesa. Somuenzaniso, PTZ mumugwagwa kamera ndiyo yakanyanyogadziriswa mune izvi, sezvo inofanira kufukidza nzvimbo huru, kusanganisira avo vane zvirongwa kure. Kutaridzika kure, zvakare, kunokubvumira kururamisa kupisa kwepanoramic nechitsipa. Nokuda kweizvi, telemetry console inowanzoshandiswa.

Vaiti ve PTZ makamera

Zvikamu zvepamusoro-tech zvakakurumidza kuzadzwa nemishonga kubva kuvakadzi vakura. Munyaya iyi, mamiriro acho ezvinhu akasiyana, sezvo zviitiko zvakabudirira zvikuru zvinoratidza makambani mashoma anozivikanwa. Mutungamiri nzvimbo inotungamirirwa neAxis PTZ kamera, kuchinjwa kwaro kunotungamirirwa kune zvose zvakasarudzwa uye zvakasikwa zvekuona mavhidhiyo emabasa. Zvimwe zvinokosha ndezvipi zvinopiwa kubva kuDahua, Geovision uye zvakabatana zvakagadziriswa zve Optimus. Pakati pemakona makuru enyika anozivikanwa, teknolojia yeTPZ inonyatsozivikanwa nevanowaniki veSamsung, kunyange nekuda kwekudhura kwechigadzirwa ichi hachisi chinhu chakakurumbira mukuenzanisa nemifananidzo inobva kune vaiti vambotaurwa.

Mhedziso

Vashandi pachavo havafariri zvekuona mavhidhiyo maitiro ehuyu. Pasinei nehutachiona hwekugadzirisa kwehutano hwemunhu mumwe nomumwe, chigadzirwa ichi chichiri kune imwe nzvimbo yakasiyana. Inzwisisa izvi uye vadziki, vachitsvaka kuvaka zvitsva uye zvishandiso, izvo zvinogona kuva ne PTZ kamera. Izvi zvinorevei mumamiriro ekukwirirana kwechikamu? Panguva ino, teknolojia inotsigira pakugadzirisa kushamwaridzana kwekukurukurirana kwekhamera uye yekutonga. Mukuita, izvi zvinoreva kusarudza nzira dzekukurukurirana pakati pezvikamu zvezvikamu zvevideo surveillance systems, uye panguva imwechete kutenderera kwakawanda kwe mechanic yemakeras uye software.
