Ungasarudza sei DVR yemotokari: wongororo uye mavhidhiyo
DVRs yagara ichishandiswa nevatyairi vakawanda, chigadzirwa ichi chave chinhu chakakosha mukamuri. Kutenda kwazviri, unogona kurekodha zvese zvinoitika kwauri uchityaira, uye kana pakaitika tsaona yemumugwagwa, unogona kuratidza kusava nemhosva kwako. Kana iwe ukaenda kune chero chitoro kana kushanyira online chitoro, iwe uchaona huwandu hwakawanda hwezvishandiso izvi, izvo zvinosiyana kubva kune mumwe nemumwe mumutengo wavo uye muhunhu hwavo.
Nzira yekusarudza DVR yakanaka yemotokari, ndeapi maitiro aunofanira kubhadhara pakutanga? Takatovhara nyaya iyi pawebhusaiti yedu Vodi.su, tichitsanangura mhando dzakakurumbira dzevanyori muna 2015.
Muchidimbu, iyo DVR idiki kamera yakaiswa pamhepo, asi mumakore achangopfuura mashandiro akawedzera zvakanyanya, uye mhando yekurekodha yakavandudzwa, uye izvi hazvishamise - tarisa kuti nharembozha dzakasvika sei mumakore gumi - kubva kune yakakura. monoblocks ane antenna uye mashoma masimba , kune yakanyanya-yakatetepa smartphones, ayo akazara-akazara mini makomputa.
Ndizvo zvakaitikawo nemarekodha evhidhiyo. Zvisinei, mabasa ose aya anodiwa here muupenyu chaihwo? Ngatikurukurei zvakadzama.
Kurekodha mhando ndiyo huru parameter.
Mafomati anotevera ari kushandiswa parizvino:
- VGA - 640x480 pixels, chimiro chekare, mumufananidzo wakadaro unogona kuona mugwagwa, mota dziri pamberi, nzira, asi haugone kusiyanisa chero chinhu chakatsanangurwa: haugone kuona nhamba, kunyange mhando dzedzimwe mota, kunze kwemavara akamonyaniswa zvinooneka;
- HD - high resolution 1280x720 pixels, mhando yekurekodha iri nani kakawanda, mavhidhiyo akadaro anogona kutariswa pachiratidziro chikuru, kunyangwe zvidiki - nhamba dzemotokari - dzinogona kuverengerwa padhuze, huyo huchavapo zvakare;
- Yakazara-HD - 1920x1080 pixels - yakanakisa mhando yemifananidzo, unogona kuona zvinenge zvese zvese, kusvika kunhamba dzemotokari dzisiri kure zvakanyanya;
- Super-HD - 2304 × 1296 - yakanyanya kugadziriswa panguva ino, mavhidhiyo akadaro anogona kutariswa pane yakakura TV skrini, mhando yacho inokufadza iwe, zvinenge zvese zvinodiwa zvichaonekwa kwauri: nhamba, zviratidzo zvemugwagwa uye zviratidzo, zviso zvevanhu zvichingodaro.
Izvi zvinoreva, kana iwe uchida kuti munyori aite basa rayo guru nemazvo, sarudza kubva kumafomati maviri ekupedzisira.
Nekudaro, kugadzirisa ndicho chimwe chezvikonzero zvinokanganisa kunaka kwekurekodha; paramita yakadai sekumhanya kwekurekodha yakakosha zvakaenzana, inoyerwa mumafuremu pasekondi. Nezviyero zvemazuva ano, kumhanya kwekurekodha kunofanirwa kunge kuri makumi maviri neshanu mafuremu pasekondi, kune mamwe mamodheru epamusoro anogona kuita makumi matatu pasekondi.
Iyo yakakwirira yemhando yevhidhiyo, iyo yakawanda nzvimbo inotora pane memori kadhi. Kune zvakare mamodheru aunogona kusarudza nemaoko kumhanya kwekurekodha, semuenzaniso, kana memori kadhi yakagadzirirwa 8 kana 16 GB, saka zviri nani kusarudza yakaderera kumhanya, kunyangwe mazhinji marekodha epakati uye epamusoro emitengo anogona. makadhi ekutsigira pa36, 64 uye kunyange 128 kana 256 Gigabyte.
Kuti uwane ruzivo rwakawanda pane memori kadhi, iwe unofanirwa kusarudza iyo chaiyo registrar zvinoenderana nefaira yekumanikidza nzira (encoder, codec, decoder).
Mafomu ekumanikidza mafaira:
- MJPEG - chimiro chekare chinoenderana nefuremu-ne-frame compression, vhidhiyo yakadai inotora nzvimbo yakawanda, ruzha runochengetwa zvakasiyana;
- MPEG4 - panguva imwe chete kudzvanywa kwemaodhiyo uye vhidhiyo hova, vhidhiyo inotora 10 nguva shoma nzvimbo;
- H.264 ndiyo yakanyanyisa kugadzirwa, inotora hafu yenzvimbo pane yapfuura, uye kunze kweiyo, pane zviri nani ruvara uye kubereka kwezwi.
Kune mafomati akaita seMOV kana AVI, mafaera evhidhiyo ari mufolda akarekodhwa mumafomati aya akanyorwa seizvi: video.mov kana video.avi. Kune zvakare mafomati akasarudzika anoshandiswa nevagadziri vega. Iyo VisionDrive fomati inozviratidza zvakanaka, iyo yakanyatsogadzirirwa kurekodha vhidhiyo pakufamba. Kuti uitembe, unofanirwa kudhawunirodha yakakosha media player chirongwa pakombuta yako.
Imwe pfungwa yakakosha ndeye husiku maitiro. Muchidimbu, iyo yehusiku modhi idambudziko rechero registrar. Mumigwagwa yeguta yakavhenekerwa, vhidhiyo inobuda kunyange yakawedzera kana kushoma yemhando yepamusoro, asi kunze kweguta, uko migwagwa isingawanzo vheneka, zvakaoma kwazvo kuona chero chinhu. Kugadzirisa mamiriro acho ezvinhu, vagadziri vazhinji vanoisa infrared illumination, asi kubva pane zvatinoona isu tichati hazvina basa.
Zvakanaka, imwe paramende yakakosha ndiyo kona yekuona. Iko kona inowanzoyerwa diagonally uye inogona kubva pa60 kusvika ku170 degrees. Tingadaidza iyo yakakwana gap - 90-140 madhigirii. Ndiyo kona iyi yekuona inozotitendera kufunga mabhendi evavakidzani. Kana kona yacho yakamanikana, saka hauzooni, semuenzaniso, mota dziri mumigwagwa yakavakidzana, asi kana kona inopfuura madhigirii 140, mufananidzo wacho unonyanya kukanganisa nekuda kweiyo fisheye effect.
Mounting nzira, kugona kutendeuka 180 madhigirii - kune maregistrars anogona kuiswa zvakachengeteka munzira dzakasiyana kurekodha hurukuro nemuongorori wemapurisa emigwagwa. Kune zvakare ayo akasungirirwa zvakasimba pane matatu matatu.
Iyo inofambisa sensor chinhu chinobatsira kwazvo, rekodhi inomuka kubva mukurara nekukurumidza kana chero kufamba kunoonekwa mumunda wekuona.
G-Sensor kana kuvhunduka sensor - yakasarudzika dhairekitori dhairekitori yakagoverwa pane memori kadhi, umo vhidhiyo yakanyorwa mumamiriro ekukurumidzira inochengetwa. Semuenzaniso, kana iwe ukarohwa kubva kumashure, kana iwe wakamanikidzwa kubhureki nesimba, vhidhiyo inochengetwa mune iyi folda uye haizodzimwa panguva yekurekodha loop.
GPS inowedzera inobatsira zvikuru. Vhidhiyo inorekodha kumhanya kwekufamba uye zuva razvino. Uye zvino, kana uchiona vhidhiyo pakombuta, unogona kuibatanidza neGoogle mepu, uye kumhanya chaiko kwekufamba kucharatidzwa pane chimwe nechimwe chikamu.
Teerera zvakare kune saizi yechiratidziro, bhatiri huwandu, basa remifananidzo, chena chiyero, sefa (kutarisa kunze kusingakodzeri radiation).
Imwe kana yakaderera yakajairwa vhidhiyo rekodhi inodhura inokwana zviuru zvina rubles.
