Umhlahlandlela Wokukhetha I-Hard Drive Engcono Kakhulu Ye-CCTV DVR
Esinye sezici ezibaluleke kakhulu ekunqumeni ikhwalithi yohlelo lokuphepha lwe-CCTV akuyona nje ikhamera noma i-DVR uqobo, kodwa futhi nemidiya yayo yokugcina. Amacala amaningi okuqoshwa okungadlali emuva, okonakaliswa ngokushesha, noma ukugcwaliswa ngokushesha kungenxa yokukhethwa kwe-hard drive (HDD) okungafanele. Ama-CCTV DVR asebenza amahora angama-24 ngosuku, ebhala idatha yevidiyo njalo, ngakho-ke izidingo zawo ze-hard drive zihlukile kweze-HDD yekhompyutha yasekhaya. Lesi sihloko sixoxa ngomhlahlandlela wokukhetha i-hard drive engcono kakhulu ye-CCTV DVR yakho ukuqinisekisa ukuqoshwa okuphephile, okuzinzile, nokuhlala isikhathi eside.
1. Qonda umehluko phakathi kwe-CCTV HDD ne-Desktop HDD
Ama-hard drive edeskithophu ngokuvamile aklanyelwe imisebenzi yansuku zonke ngezikhathi ezithile. Okwamanje, ama-CCTV DVR enza ukuqopha okuqhubekayo (ukubhala okuqhubekayo), okufaka ingcindezi enkulu ku-motor ye-HDD, ikhanda, kanye nezingxenye zangaphakathi.
Ama-HDD aqondene ne-CCTV (avame ukubizwa ngokuthi ama-HDD okuqapha) ngokuvamile analokhu:
– Kwenzelwe ukusebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto, kufanelekile ukuqopha ngaphandle kokuma.
- I-firmware ekhethekile yokusingatha ukusakazwa kwevidiyo okuningi (ukusakaza okuningi) kusuka kumakhamera amaningi ngesikhathi esisodwa.
– Ukuphathwa kwamaphutha ngendlela efanele ekurekhodweni kwevidiyo. Ezinhlelweni ze-CCTV, ukubambezeleka kokufunda/ukubhala kungabangela ukuwa kohlaka noma ukuqoshwa kweqiwe.
– Isilinganiso esiphezulu sokukhuthazela kanye nomthwalo womsebenzi kunama-HDD avamile edeskithophu.
Uma ufaka i-HDD yedeskithophu ku-DVR, ingase isebenze, kodwa ingozi yokushisa ngokweqile, ukwehluleka, noma ukuqoshwa okungazinzile inkulu kakhulu—ikakhulukazi ezinhlelweni ezinamakhamera amaningi noma ezinezinqumo eziphakeme.
2. Thola Umthamo Ngokusekelwe Ezidingweni Zokurekhoda
Ukukhetha i-HDD engcono kakhulu akusho njalo ukuthi inkulu kunazo zonke, kodwa kunalokho ifanelana kahle nemigomo yakho yokugcina (isb., izinsuku ezingu-7, izinsuku ezingu-14, noma izinsuku ezingu-30). Umthamo uthonywa yizici eziningana:
1. Inani lamakhamera (isib. iziteshi ezingu-4, 8, 16).
2. Isixazululo (2MP/1080p, 4MP, 5MP, 8MP/4K).
3. Izinga lohlaka (FPS): I-10 fps isebenza kahle kakhulu kune-25/30 fps.
4. I-compression codec: I-H.265/H.265+ isebenza kahle kakhulu kune-H.264.
5. I-Bitrate: uma ikhwalithi iphakeme, isikhala esidingekayo siba sikhulu.
6. Imodi yokuqopha: Ukutholwa okugcwele kwamahora angama-24 noma ukunyakaza kuphela.
Isibonelo esilula, uhlelo olunamakhamera amane lwe-1080p olunezilungiselelo ezisebenza kahle ze-H.265 lunganele nge-1–2TB isikhathi sokugcina esingaba yizinsuku eziyi-7–14, kodwa ezinye izilungiselelo zingahluka kakhulu. Uma uhlose isikhathi eside sokugcina (isb., izinsuku ezingama-30) ngamakhamera ayisishiyagalombili e-4MP, cabanga ngomthamo omkhulu, njenge-4TB–8TB, noma cabanga ngohlelo lokugcina olunezigaba.
Icebiso eliwusizo: uma ungabaza, kuphephile ukukhetha umthamo omkhulu kancane ukuze i-DVR ingabhali ngokushesha amarekhodi amadala ngaphambi kokuba kufinyelelwe isikhathi sakho sokugcina osifunayo.
3. Khetha Uhlobo lwe-HDD Oluklanyelwe Ngokukhethekile Ukuqapha
Kuma-CCTV DVR/NVR, okubaluleke kakhulu ukuzinza kokubhala, hhayi isivinini sokufunda esiphezulu njengalezo zokudlala. Khetha i-HDD ethengiswayo ukuze ihlolwe. Uzothola amamodeli anjengalawa:
– I-WD Purple (Ukuqapha)
– I-Seagate SkyHawk (Ukuqapha)
Zombili zivame ukusetshenziswa kuma-DVR/NVR ngoba zenzelwe imisebenzi engu-24/7. Ngaphandle komkhiqizo, naka uchungechunge olufanele—njengoba umkhiqizo ngamunye ungaba nemigqa ehlukene yedeskithophu, i-NAS, ibhizinisi, kanye nokuqapha.
4. Naka usayizi: 3.5 amayintshi vs 2.5 amayintshi
Ama-DVR amaningi e-CCTV asebenzisa ama-HDD angu-3.5 intshi (njengama-PC HDD), ngoba:
– Umthamo omkhulu.
– Intengo nge-TB ngayinye iyonga kakhulu.
– Ngokuvamile ukusebenza nokuqina kufaneleka kakhulu ezinhlelweni ezimile.
Ama-HDD angu-2.5 intshi ngokuvamile asetshenziselwa amadivayisi/ama-laptop aphathekayo. Amanye ama-DVR asekela ama-drive angu-2.5 intshi, kodwa amandla awo nokuqina kwawo kokusetshenziswa amahora angu-24 ngosuku, izinsuku eziyi-7 ngesonto akuvamile ukuba kuhle njengama-drive angu-3.5 intshi. Uma i-DVR yakho isekela ama-drive angu-3.5 intshi, kuyisinqumo esiphephile kakhulu sohlelo oluhlala njalo.
5. Lungisa isivinini sokujika bese ugxila ekuzinzeni
Uma kukhulunywa nge-CCTV, i-HDD engu-5400 RPM ivame ukwanele, njengoba imfuneko yayo eyinhloko ukubhala idatha yevidiyo okuzinzile. I-HDD engu-7200 RPM ngezinye izikhathi inikeza ukusebenza okuphezulu, kodwa ingenza okulandelayo:
– Kushisa kakhulu.
– Ukusetshenziswa kwamandla okuphezulu.
– Kungaba nomsindo kakhulu.
Kumasistimu amaningi e-DVR asekhaya/amabhizinisi amancane, i-HDD yokuhlola engu-5400–5900 RPM ifanelekile. Uma usebenzisa amakhamera amaningi anesinqumo esiphezulu noma i-NVR ene-bitrate ephezulu, hlola izincomo zomkhiqizi we-DVR/NVR kanye nemininingwane ye-HDD ukuqinisekisa ukuthi ingakwazi ukusingatha umthwalo wokusakaza.
6. Hlola “Isilinganiso Somthwalo Womsebenzi” kanye Nenani Lamakhamera Asekelwayo
Imininingwane ebalulekile evame ukunganakwa yisilinganiso somsebenzi (isb., ukuthi zingaki i-TB/ngonyaka) kanye nenani lemifudlana/amakhamera asekelwayo. Ama-HDD okuqapha ngokuvamile achaza inani lamakhamera angakwazi ukuwaphatha kahle.
Uma uhlelo lukhulu (isib. amakhamera angu-16 e-4MP asebenza amahora angu-24 ngosuku, izinsuku ezingu-7 ngesonto), kulapho udinga khona i-HDD enomsebenzi omningi, noma isu:
– Ukusebenzisa ama-HDD angaphezu kweyodwa (uma i-DVR isekela).
– Cabangela izinketho ze-NVR ngesitoreji se-NAS/RAID, uma isikali sikhulu.
Uma i-DVR yakho inikeza isikhala esisodwa se-HDD kuphela, ukukhetha i-HDD elinganiswe ngokubhekisisa kuba kubaluleke nakakhulu ngoba wonke umthwalo womsebenzi uncike kuleyo drive eyodwa.
7. Cabanga Ngokuhlala Isikhathi Eside, Iwaranti, kanye Nodumo
Ngenxa yokuthi ama-DVR aqopha ngokungayeki, i-HDD yingxenye eguga ngokushesha. Ngakho-ke, cabanga ngalokhu:
– Iwaranti esemthethweni (ngokuvamile iminyaka engu-2-3 yochungechunge lokuqapha, ingahluka kuye ngemodeli/izwe).
– Imikhiqizo iqinisekiswa ngabasabalalisi abasemthethweni ukuze kugwenywe izinkinga zesimangalo.
– Idumela lochungechunge lwe-HDD ekusetshenzisweni kwangempela kokuqapha.
Khumbula: I-HDD eshibhile kodwa eshesha kakhulu ingagcina ikubize kakhulu ngoba ulahlekelwa yizithombe ezibalulekile futhi kufanele uyishintshe idrayivu ngokushesha.
8. Qinisekisa ukuthi iyahambisana ne-DVR yakho
Ngaphambi kokuthenga, hlola okulandelayo:
– Umthamo omkhulu osekelwa yi-DVR (isb. umkhawulo ophezulu yi-6TB/8TB/10TB ngesikhala ngasinye).
– Isikhombimsebenzisi: ngokuvamile i-SATA.
– Ukusekelwa kwenqubo yokufometha nokuqalisa: amanye ama-DVR acela inqubo "yefomethi" ye-HDD kumenyu ye-DVR.
Uma ufake i-HDD entsha, yiqalise usebenzisa i-DVR bese uqinisekisa ukuthi isimo “Sijwayelekile/Siphilile”.
9. Gwema Amaphutha Avamile
Amanye amaphutha avamile lapho ukhetha i-HDD ye-CCTV DVR:
1. Ukusebenzisa i-HDD esetshenzisiwe evela kwi-PC endala. Kungenzeka ngokobuchwepheshe, kodwa ingozi inkulu ngenxa yokuguga kanye nemikhakha emibi ayibonakali ngaso sonke isikhathi ngokushesha.
2. Uma sicabanga ukuthi wonke ama-HDD afana. Kodwa-ke, i-firmware kanye nomklamo womsebenzi kuthinta kakhulu ukuzinza kokuqopha.
3. Ukunganaki ukushisa. Ama-DVR abekwe ezindaweni ezivalekile ngaphandle komoya abangela ukuthi i-HDD ishise ngokushesha futhi inciphise isikhathi sayo sokuphila.
4. Ukungabalwa kwezidingo zomthamo ukuze okuqoshiwe kususwe ngokushesha (kubhalwe ngaphezulu).
Isixazululo: khetha i-HDD entsha yokuqapha, faka i-DVR endaweni epholile/enomoya, bese usetha imodi ye-bitrate kanye neyokurekhoda njengoba kudingeka.
10. Izincomo Eziwusizo Ezisekelwe Esikalini Sokusetshenziswa
Nasi umhlahlandlela osheshayo (ojwayelekile) wokwenza izinto zibe lula:
– Ikhaya (amakhamera angu-2–4 angu-1080p/2MP): i-HDD yokuqapha engu-1TB–2TB.
– Isitolo esincane (amakhamera angu-4–8 angu-1080p–4MP): i-HDD yokuqapha engu-2TB–4TB.
– Imakethe yehhovisi/encane (amakhamera angu-8–16 e-4MP): 4TB–8TB, cabanga nge-DVR enezikhala eziningi noma uhlelo olunwebekayo.
– Isikali esikhulu: kuphephile ukusebenzisa i-NVR+NAS/RAID noma ama-HDD amaningi ukuze umthwalo ungahlali kudrayivu eyodwa.
Izibalo ezingenhla zisadinga ukulungiswa ngokuya ngezilungiselelo zesikhathi sokugcina isitoreji se-bitrate, i-fps, i-codec, kanye ne-target recording.
Isiphetho
Ukukhetha i-hard drive engcono kakhulu ye-CCTV DVR yakho kuyindaba yokufanisa izidingo zokurekhoda ezingama-24/7 nomthamo wedivayisi, ukuqina kwayo, kanye nokuhambisana kwayo. Beka phambili i-HDD yokuqapha ezinikele, bala izidingo zakho zomthamo ngokusekelwe enanini lamakhamera nekhwalithi yevidiyo, futhi uqinisekise ukuthi i-DVR yakho isekela umthamo we-HDD oyikhethayo. Ngokukhetha i-HDD efanele, uzothola ukuqoshwa okuzinzile, unciphise ingozi yokulahleka kwedatha, futhi unikeze uhlelo lokuphepha oluthembeke kakhulu.
Uma ufuna, sicela ucacise inani lamakhamera, i-resolution, i-codec (H.264/H.265), kanye nenani lezinsuku zokugcina eliqondiwe, khona-ke ngingakusiza ukubala isilinganiso somthamo we-HDD esifaneleka kakhulu se-DVR yakho.
