Tilmaamaha Doorashada Hard Drive-ka ugu Fiican ee CCTV DVR
Mid ka mid ah arrimaha ugu muhiimsan ee lagu go'aaminayo tayada nidaamka amniga CCTV ma aha oo kaliya kamaradda ama DVR lafteeda, laakiin sidoo kale warbaahinta kaydinta. Kiisas badan oo duubis ah oo aan dib u ciyaarin, si dhakhso ah loo kharribo, ama si dhakhso ah loo buuxiyo ayaa sabab u ah xulashada hard drive-ka aan habboonayn (HDD). CCTV DVRs waxay shaqeeyaan 24 saacadood maalintii, iyagoo si joogto ah u qoraya xogta fiidiyowga, sidaa darteed shuruudaha hard drive-kooda way ka duwan yihiin kuwa HDD-ga kombiyuutarka guriga. Maqaalkani wuxuu ka hadlayaa hage ku saabsan doorashada hard drive-ka ugu fiican ee CCTV DVR-gaaga si loo hubiyo duubisyo ammaan ah, deggan, iyo waara.
1. Fahmo Farqiga u dhexeeya CCTV HDD iyo Desktop HDD
Darawalada adag ee desktop-ka guud ahaan waxaa loogu talagalay shaqooyinka maalinlaha ah ee kala go'a. Dhanka kale, CCTV DVR-yadu waxay sameeyaan duubis joogto ah (qoris joogto ah), taas oo culeys badan saarta matoorka, madaxa, iyo qaybaha gudaha ee HDD-ga.
HDD-yada gaarka u ah CCTV (badanaa loo yaqaan HDD-yada la socodka) waxay caadi ahaan leeyihiin:
- Waxaa loo habeeyay hawlgalka 24/7, oo ku habboon duubista aan joogsiga lahayn.
- Qalab gaar ah oo lagu maareeyo durdurro fiidiyowyo badan (multi-stream) oo ka imanaya kamarado badan hal mar.
- Maareynta khaladaadka saxda ah ee duubista fiidiyowga. Nidaamyada CCTV, dib u dhaca akhriska/qorista waxay sababi karaan hoos u dhac ku yimaada qaab-dhismeedka ama duubista la boodo.
- Qiimayn dulqaad iyo culays shaqo oo ka sarreeya HDD-yada caadiga ah ee desktop-ka.
Haddii aad ku rakibto HDD desktop ah DVR-ka, way shaqayn kartaa, laakiin khatarta ah in aad u kululaato, fashilmo, ama duubis aan degganayn ayaa aad uga badan - gaar ahaan nidaamyada leh kamarado badan ama xallin sare.
2. Go'aami Awoodda Iyada oo ku saleysan Baahiyaha Diiwaangelinta
Doorashada HDD-ga ugu fiican had iyo jeer macnaheedu maaha kan ugu weyn, laakiin waa kan ugu habboon yoolalkaaga kaydinta (tusaale ahaan, 7 maalmood, 14 maalmood, ama 30 maalmood). Awoodda waxaa saameeya dhowr arrimood:
1. Tirada kamaradaha (tusaale ahaan 4, 8, 16 kanaal).
2. Xallinta (2MP/1080p, 4MP, 5MP, 8MP/4K).
3. Heerka qaab-dhismeedka (FPS): 10 fps ayaa ka waxtar badan 25/30 fps.
4. Koodhka isku-dhafka: H.265/H.265+ wuu ka waxtar badan yahay H.264.
5. Heerka Bitrate-ka: tayada oo sareysa, booska loo baahan yahay ayaa sii weynaanaya.
6. Habka duubista: 24 saacadood oo buuxa ama ogaanshaha dhaqdhaqaaqa oo keliya.
Tusaale ahaan, nidaam afar kamaradood ah oo 1080p ah oo leh cadaadis H.265 iyo dejimo hufan ayaa ku filnaan kara 1-2TB muddo haynta ah oo qiyaastii ah 7-14 maalmood, laakiin qaabaynta kale way kala duwanaan kartaa si weyn. Haddii aad higsanayso muddo haynta oo dheer (tusaale ahaan, 30 maalmood) oo leh siddeed kamaradood oo 4MP ah, tixgeli awood weyn, sida 4TB-8TB, ama tixgeli nidaam kaydin oo heer sare ah.
Talo wax ku ool ah: marka aad shaki qabtid, way ka ammaan badan tahay inaad doorato awood yar oo ka weyn si DVR uusan si dhakhso ah u tirtirin duubitaanadii hore ka hor inta aan la gaarin muddada haynta ee aad rabto.
3. Dooro Nooca HDD-ga oo si gaar ah loogu talagalay Ilaalinta
CCTV DVRs/NVRs, mudnaanta koowaad waa xasilloonida qorista, ee maaha xawaaraha akhriska sare sida kuwa ciyaaraha. Dooro HDD loo suuqgeeyay si loo ilaaliyo. Badanaa waxaad ka heli doontaa moodooyinka sida:
– WD Purple (Dabagalka)
– Seagate SkyHawk (Dabagalka)
Labadaba waxaa badanaa loo isticmaalaa DVR-yada/NVR-yada sababtoo ah waxaa loogu talagalay culayska shaqada 24/7. Marka laga reebo summada, fiiro gaar ah u yeelo taxanaha saxda ah—maadaama summad kastaa ay yeelan karto khadad kala duwan oo loogu talagalay desktop-ka, NAS-ka, ganacsiga, iyo la socodka.
4. Fiiro gaar ah u yeelo cabbirka: 3.5 inji iyo 2.5 inji
Inta badan CCTV DVR-yadu waxay isticmaalaan HDD-yada 3.5 inji ah (sida PC HDD-yada), sababtoo ah:
– Awood ballaaran.
– Qiimaha halkii TB waa mid dhaqaale ahaan ka jaban.
– Guud ahaan waxqabadka iyo cimri dhererkuba way ku habboon yihiin nidaamyada taagan.
HDD-yada 2.5-inji ah waxaa badanaa loo isticmaalaa aaladaha/laptop-yada la qaadi karo. Qaar ka mid ah DVR-yadu waxay taageeraan darawallada 2.5-inji ah, laakiin awooddooda iyo cimri dhererkooda isticmaalka 24/7 badanaa ma aha kuwo la mid ah darawallada 3.5-inji ah. Haddii DVR-gaagu uu taageero darawallada 3.5-inji ah, waa doorashada ugu ammaansan nidaamka joogtada ah.
5. Hagaaji Xawaaraha Wareegga oo Diiradda saar Xasilloonida
Marka laga hadlayo CCTV, HDD 5400 RPM ayaa badanaa ku filan, maadaama shuruudaheeda aasaasiga ah ay tahay qorista xogta fiidiyowga oo deggan. HDD 7200 RPM mararka qaarkood waxay bixisaa waxqabad sare, laakiin waxay awood u yeelan kartaa:
– Ka kulul.
– Isticmaalka korontada oo sareeya.
– Waxay noqon kartaa mid buuq badan.
Nidaamyo badan oo guryaha/ganacsiga yaryar ah, HDD-ga ilaalada ee 5400–5900 RPM ayaa ku habboon. Haddii aad isticmaaleyso kamarado badan oo xallin sare leh ama NVR-ga xawaaraha sare leh, hubi talooyinka soo saaraha DVR/NVR iyo qeexitaannada HDD-ga si aad u hubiso inay xamili karto culayska socodka.
6. Hubi "Qiimaynta Culayska Shaqada" iyo Tirada Kaamirooyinka la Taageero
Tilmaamaha muhiimka ah ee inta badan la iska indho tiro waa qiimeynta culeyska shaqada (tusaale ahaan, inta TB/sanadka) iyo tirada durdurrada/kamaradaha la taageerayo. HDD-yada kormeerka guud ahaan waxay qeexaan tirada kamaradaha ay si fiican u qaban karaan.
Nidaamka oo sii weyn (tusaale ahaan 16 kamaradood oo 4MP ah oo shaqeynaya 24/7), ayaa inta badan aad u baahan tahay HDD shaqo oo sarreeya, ama xitaa istaraatiijiyad:
- Isticmaalka in ka badan hal HDD (haddii DVR ay taageerto).
– Ka fiirso ikhtiyaarada NVR oo leh kaydinta NAS/RAID, haddii miisaanku weyn yahay.
Haddii DVR-gaagu uu bixiyo hal boos oo HDD ah oo keliya, markaas doorashada HDD-ga la qiimeeyo ee la socodka ayaa aad muhiim u noqonaysa sababtoo ah shaqada oo dhan waxay ku tiirsan tahay hal wadistaas.
7. Ka fiirso Waarta, Dammaanadda, iyo Sumcadda
Maadaama DVR-yadu ay si aan kala joogsi lahayn u duubaan, HDD-gu waa qaybta ugu da'da badan. Markaa, tixgeli:
– Dammaanad rasmi ah (badanaa 2-3 sano oo loogu talagalay taxanaha dabagalka, way kala duwanaan kartaa iyadoo ku xiran nooca/waddanka).
- Badeecadaha waxaa damaanad qaadaya qaybiyeyaasha rasmiga ah si looga fogaado dhibaatooyinka sheegashada.
- Sumcadda taxanaha HDD ee isticmaalka dhabta ah ee kormeerka.
Xusuusnow: HDD raqiis ah laakiin si dhakhso ah u sii xumaanaya ayaa ku dambayn kara kharash badan sababtoo ah waxaad waayi doontaa muuqaallo muhiim ah oo waa inaad si dhakhso ah u beddeshaa darawalka.
8. Hubi in aad la jaanqaadi karto DVR-gaaga
Kahor intaadan iibsan, hubi kuwa soo socda:
- Awoodda ugu badan ee ay taageerto DVR (tusaale ahaan ugu badnaan 6TB/8TB/10TB halkii boos).
– Is-dhexgalka: guud ahaan SATA.
– Taageerada habka qaabaynta iyo bilaabista: qaar ka mid ah DVR-yadu waxay codsadaan habka "qaabaynta" HDD ee ku jira liiska DVR.
Haddii aad rakibtay HDD cusub, ka bilow DVR-ka oo hubi in xaaladdu ay tahay "Caadi/Caafimaad".
9. Ka fogow khaladaadka caadiga ah
Khaladaadka caadiga ah marka la dooranayo HDD-ga CCTV DVR:
1. Isticmaalka HDD la isticmaalay oo laga sameeyay kombiyuutar duug ah. Farsamo ahaan waa suurtagal, laakiin khatartu way badan tahay da'da awgeed, qaybaha xunna had iyo jeer si dhakhso ah uma muuqdaan.
2. Haddii dhammaan HDD-yadu isku mid yihiin. Si kastaba ha ahaatee, naqshadeynta firmware-ka iyo shaqada culus waxay si weyn u saameeyaan xasilloonida duubista.
3. Dareen la'aanta kuleylka. DVR-yada la dhigo meelaha xiran ee aan lahayn hawo-qaadis waxay keenaan in HDD-gu si dhakhso ah u kululaado oo uu gaabiyo cimrigiisa.
4. Lama xisaabin shuruudaha kartida si duubista si dhakhso ah loo tirtiro (looma qoro).
Xalka: dooro HDD cusub oo la socosho ah, ku rakib DVR-ka meel qabow/hawo leh, oo deji qaabka bitrate-ka iyo duubista hadba sida loogu baahdo.
10. Talooyin Wax Ku Ool ah oo Ku Salaysan Miisaanka Isticmaalka
Waa kan hage degdeg ah (guud) si wax loo fududeeyo:
– Hoyga (2–4 kamarado 1080p/2MP ah): 1TB–2TB HDD ilaalo ah.
– Dukaan yar (4–8 kamarado 1080p–4MP ah): HDD-ga ilaalada 2TB–4TB.
– Suuq xafiis/yar (8–16 kamarado 4MP ah): 4TB–8TB, tixgeli DVR-ga badan ama nidaamka la ballaarin karo.
– Cabbir weyn: way ka ammaan badan tahay in la isticmaalo NVR+NAS/RAID ama HDD badan si culaysku uusan ugu nasan hal darawal.
Tirooyinka kor ku xusan wali waxay u baahan yihiin in la hagaajiyo iyadoo loo eegayo xawaaraha bitrate-ka, fps-ka, codec-ga, iyo dejimaha waqtiga kaydinta ee bartilmaameedka ah.
Gabagabo
Doorashada darawalka adag ee ugu fiican CCTV DVR-gaaga waa arrin ku saabsan iswaafajinta baahiyaha duubista 24/7 iyo awoodda qalabka, cimri dhererka, iyo iswaafajinta. Mudnaanta sii HDD-ga ilaalada ee gaarka ah, xisaabi baahiyahaaga awoodda iyadoo lagu saleynayo tirada kamaradaha iyo tayada fiidiyowga, oo hubi in DVR-gaagu uu taageerayo awoodda HDD-ga ee aad doorato. Markaad doorato HDD-ga saxda ah, waxaad gaari doontaa duubitaan deggan, waxaad yareyn doontaa khatarta luminta xogta, waxaadna bixin doontaa nidaam amni oo aad loogu kalsoonaan karo.
Haddii aad rabto, fadlan sheeg tirada kamaradaha, xallinta, codec-ga (H.264/H.265), iyo tirada maalmaha la keydiyo ee bartilmaameedka ah, markaa waxaan kaa caawin karaa inaad xisaabiso qiyaasta awoodda HDD ee ugu habboon DVR-gaaga.
