Makhadi okumbukira ndiwonyamula deta yodalirika komanso yodalirika, chifukwa chomwe, osachepera apo, kuwonekera kwa makanema ojambulira pamtengo angakwanitse. Lero tikuthandizani kusankha khadi yoyenera ya chipangizo chanu.
Njira Zosankha Khadi
Makhalidwe ofunikira a SD-makhadi ofunikira pakugwira ntchito kwa wojambulira amaphatikizapo zizindikiro monga kufananirana (mtundu wothandizidwa, mtundu woyenera ndi wothamanga), voliyumu ndi wopanga. Tiyeni tiwone onse mwatsatanetsatane.
Kugwirizana
Ma DVR amakono amagwiritsa ntchito miyezo ya SDHC ndi SDXC ngati makadi okumbukira mu ma fomu a SD ndi / kapena ma MicroSD. Nthawi zina amagwiritsa ntchito miniSD, koma chifukwa cha kusowa kwawotere, amakhala osatchuka.
Zoyimira
Mukamasankha kakhadi kachipangizo kanu, werengani mosamala muyezo wa media omwe ali nawo. Mwachilengedwe, zida zambiri zotsika mtengo zimapanga kanema mu mtundu wa HD, womwe umagwirizana ndi muyezo wa SDHC. Komabe, ngati kujambula kanema wa FullHD kulembedwa pamachitidwe a chipangizocho, mwina chimafunikira khadi yokhazikika ya SDXC.
Mtundu
Mtunduwu ndiwosafunikira kwenikweni: ngakhale ngati wolembetsa wanu atagwiritsa ntchito makadi okumbukira akulu, mutha kugula chosinthira cha MicroSD ndikugwiritsa ntchito chomaliza.
Komabe, pankhaniyi, muyenera kusamala: zikuwoneka kuti wolembetsa amafunikira ndendende makadi a SD, ndipo sagwira ntchito ndi zina mawonekedwe ngakhale kudzera pa adapter.
Onaninso: DVR sawona khadi yokumbukira
Gulu lothamanga
Makalasi akuthamanga kwambiri omwe ma DVR amathandizira ndi Class 6 ndi Class 10, yomwe imafanana ndi kulemba kochepa kwambiri kwa data 6 ndi 10 MB / s. Pazida zamtundu wapamwamba kwambiri, thandizo la UHS limapezekanso, popanda zomwe sizingatheke kujambula mavidiyo pazisankho zazikulu. Kwa ojambula otsika mtengo okhala ndi chizolowezi choyambira kugwira ntchito kwa VGA, mutha kugula khadi ya Class 4. Zowonekera zamakalasi othamanga afotokozedwa mwatsatanetsatane m'nkhaniyi.
Voliyumu
Kanema ndi amodzi mwa mitundu yamtundu wotchuka kwambiri, kotero pazida zojambulira za digito, zomwe ndi zojambulira, muyenera kusankha kuyendetsa pamagalimoto ambiri.
- Zochepetsetsa zochepa zitha kumayesedwa ngati 16 GB drive, yomwe ili yofanana ndi maola 6 a HD-video;
- Kukula komwe amakonda ndi 32 kapena 64 GB, makamaka makanema apamwamba (FullHD kapena kuposa);
- Makhadi okhala ndi mphamvu ya 128 GB kapena kuposerapo ayenera kugulidwa kokha pazida zomwe zimathandizira kuthetsa kutalika kwa liwiro ndi kuthamanga kwambiri.
Wopanga
Ogwiritsa ntchito samvera chidwi kwenikweni ndi omwe amapanga makadi amakumbukidwe omwe akufuna kugula: gawo lamtengo ndilofunika kwambiri kwa iwo. Komabe, monga zowonetsera, makadi ndi okwera mtengo kwambiri kuchokera kumakampani akuluakulu (SanDisk, Kingston, Sony) ndi odalirika kuposa ochokera kumakampani omwe sadziwika.
Pomaliza
Kuti tifupikitse izi pamwambapa, titha kuona njira yabwino kwambiri ya memory memory ya DVR. Kuyendetsa uku ndi 16 kapena 32 GB mu mtundu wa MicroSD (monga momwe alili kapena ndi adapter ya SD), SDHC yokhazikika komanso kalasi 10 kuchokera kwa wopanga wodziwika bwino.
