NVR vs. DVRFuafuaga Teuina & Codecs

O lo'o iai le tele o le teuina NVR ma le DVR fa'alelei manuia pe le manuia. Pe e te faamaumauina analog (DVR) poʻo IP vaitafe (NVR), atoa bitrate ta'avale aso o le taofiga. H.265 (ma faʻatau codec atamai) e masani ona tipi le teuina 30-50% vs H.264, ae fa'alagolago lau maila gaioiga fa'aaliga, iugafono, ma fua fa'avaa.

Fua fa'atatau (fa'afaigofie)

• Aofa'iga o la'asaga (Mbps) × sekone/aso (86,400) ÷ 8 = MB/aso.

• Faatele i numera o meapueata ma aso taofi; faaopoopo ~10–20% luga.

Filifiliga e fai

• Fa'aauau vs fa'avae pu'eina (faagaioiga e sefe le teuina ae mana'omia le fa'alogo).

• I'uga/Fa'avaa fua faatatau: 4K @ 15–20 fps e taatele mo le iloagofie; 1080p @ 10–15 fps mo se vaaiga lautele.

• Codec: E sili H.265 pito-i-pito; fa'amaonia uma NVR ma meapueata lagolagoina.

• Ituaiga teuina: Su'esu'e-vaega HDDs, faitalia RAID 5/6, vevela-fa'asao. Mo nofoaga tetele, mafaufau NAS/SAN ma iSCSI pe NFS.

DVR vs NVR nuances

• DVR: itiiti ki codec; ta'i ta'i ala bitrate e masani ona tapuni, o lea e sa'o lelei fuafuaga o le gafatia.

• NVR: sili atu fetuutuunai (VBR/CBR, GOP, codec atamai), ae faigofie ona faʻafuaseʻi overshoot teuina ma 4K mea pueata.

NVR vs. DVRAvanoa Mamao & Fa'atasi

E lua DVR ma NVR tulaga ofoina polokalama feavea'i ma P2P ao feso'ota'iga mo va'aiga mamao. O le ese'esega o le lelei o lo latou fa'atasia ma le fa'aputuga fa'aputuga lautele ma mea faigaluega lona tolu. NVR/IP tautala faiga RTSP, ONVIF, ma e masani lava API malolo, fa'afaigofie ona gaugau i totonu VMS, pulea avanoa, laulau fa'ailo, pe SOC dashboards.

Avanoa avanoa mamao

• Fa'atau P2P: Fa'atonu sili ona faigofie; galue i tua o le NAT.
