Isici Sokuqopha Isikhathi Okuzenzakalelayo Kumarekhodi E-CCTV
Ezinhlelweni zokuphepha zanamuhla, amakhamera e-CCTV awasebenzi nje kuphela njengamathuluzi okuqapha okubonakalayo kodwa futhi njengamadivayisi okubhala agcina ubufakazi bezehlakalo ngokulandelana kwezikhathi. Esinye sezici ezibaluleke kakhulu—kodwa ezivame ukunganakwa—ukufaka isitembu sesikhathi ngokuzenzakalela kumavidiyo e-CCTV. Lesi sici sibonisa isikhathi nosuku ngqo kuvidiyo, noma sigcina njenge-metadata engatholakala uma kudingeka. Lesi sihloko sixoxa ngokuthi kuyini ukufaka isitembu sesikhathi ngokuzenzakalela, ukuthi kusebenza kanjani, ukuthi kungani kubalulekile, kanye nemikhuba emihle yokuqinisekisa ukuthi lesi sici sinembile futhi sithembekile uma sidingeka.
Kuyini Ukuqopha Isikhathi Okuzenzakalelayo ku-CCTV?
Ukuqopha isikhathi okuzenzakalelayo kuyisici esivumela izinhlelo ze-CCTV ukuthi zengeze ulwazi losuku nesikhathi kumavidiyo aqoshiwe. Lolu lwazi luvame ukuboniswa njengembondela encane yombhalo ekhoneni lesikrini. Kwezinye izinhlelo, ngaphezu kwembondela, isikhathi sigcinwa njenge-metadata ngaphakathi kwefayela levidiyo, okwenza kube lula ukusesha nokuvumelanisa.
Izitembu zesikhathi ngokuvamile ziqukethe:
– Usuku (ifomethi ingaba u-DD/MM/YYYY noma u-YYYY-MM-DD)
– Amahora, imizuzu, imizuzwana (HH:MM:SS)
– Ngezinye izikhathi izindawo zesikhathi (isb. GMT+7)
– Ngezinye izikhathi ubunikazi bekhamera noma isiteshi (i-Cam 01, i-Lobby, i-Warehouse)
Ngalolu lwazi, ividiyo ayibonisi nje kuphela "okwenzekile", kodwa futhi "nokuthi kwenzeke nini" ngokunembile.
Kungani Izitembu Zesikhathi Zibaluleke Kangaka?
1. Ukuqinisa Ubufakazi Bokubaluleka Kokuqoshwa
Ezimweni zophenyo, izithombe ze-CCTV zivame ukusetshenziswa njengobufakazi obusekelayo. Izitembu zesikhathi zisiza ekusunguleni ukulandelana kwemicimbi futhi zixhumanise izithombe nezinye izehlakalo, njengemibiko yezokuphepha, izingodo zokungena emnyango, noma ukuthengiselana kwabakhokhi. Ngaphandle kwezitembu zesikhathi, izithombe zingaba nemibuzo: izenzakalo zingase zibonakale zicacile, kodwa isikhathi asiqinisekile.
2. Kwenza kube lula ukusesha okuqoshiwe
Enye yezinselele ezinkulu ekuphathweni kwe-CCTV ukuthola ividiyo ethile phakathi kwamahora noma izinsuku zevidiyo. Ngezitembu zesikhathi ezinembile, abaqhubi bangagxumela ngqo esikhathini sesigameko, njengokuthi "02:13 ekuseni," ngaphandle kokubuyisela emuva ividiyo kusukela ekuqaleni.
3. Ukuvumelanisa Amakhamera Amaningi
Emahhovisi, ezindaweni zokugcina impahla, ezikoleni, noma ezindaweni zomphakathi, kuvame ukuba namakhamera amaningi. Uphenyo luvame ukudinga ukuqoshwa kusuka kuma-engeli amaningi ngesikhathi esisodwa. Izitembu zesikhathi ezihambisanayo phakathi kwamakhamera zivumela ukuvumelanisa okusheshayo. Uma amawashi ehluka ngisho nangemizuzu embalwa phakathi kwamakhamera, ukuhlaziywa kwezehlakalo kungaphambaniswa futhi ukulandelana kwezikhathi kungaba nzima.
4. Isekela ukuzenzekela kanye nokuhlaziya
Izinhlelo eziningi zesimanje zisebenzisa ukuhlaziya kwamavidiyo, njengokutholwa kokunyakaza, ukuqashelwa kwepuleti lelayisense, noma ukubalwa kwabantu. Idatha yokuhlaziya ivame ukugcinwa nezitembu zesikhathi. Izitembu zesikhathi ezinembile ziqinisekisa ukuthi izehlakalo ezitholiwe zinereferensi yesikhathi evumelekile yokubika nokuhlola.
Indlela Okusebenza Ngayo Ukuqopha Isikhathi Okuzenzakalelayo
Ngokuvamile, isikhathi sokuqoshwa kwe-CCTV singavela emithonjeni eminingana:
1. Iwashi Langaphakathi le-DVR/NVR/Ikhamera
Amadivayisi okurekhoda (ama-DVR amakhamera e-analog, ama-NVR amakhamera e-IP) anamawashi angaphakathi. Amanye amakhamera e-IP nawo agcina amawashi awo. Uma engavumelanisiwe, lawa mawashi angaphakathi angahamba ngokuhamba kwesikhathi (ukuhamba kwewashi), ikakhulukazi kumadivayisi ashibhile noma amadala.
2. Vumelanisa ne-NTP (Iphrothokholi Yesikhathi Senethiwekhi)
Ukuze kugcinwe ukunemba, izinhlelo eziningi zihlinzeka ngokuvumelanisa okuzenzakalelayo nge-NTP. Amadivayisi azofanisa isikhathi sawo neseva yesikhathi ku-inthanethi noma iseva yendawo yenkampani. Lena yindlela evame kakhulu futhi enconywayo, njengoba igcina iwashi elizinzile nelihambisanayo kumadivayisi amaningi.
3. Ukuvumelanisa neSistimu Ephakathi
Endaweni yebhizinisi, isikhathi singavunyelaniswa ngeseva yangaphakathi (isb., iseva yesizinda noma iseva yesikhathi esizinikele). Le ndlela yandisa ukulawula, ikakhulukazi lapho ukufinyelela kwe-inthanethi kuvinjelwe.
Isitembu Sesikhathi Esimboziwe vs I-Metadata: Uyini Umehluko?
Imbondela Yesitembu Sesikhathi
- Kubonwe ngqo kuvidiyo.
– Kunzima ukususa ngaphandle kokushintsha ividiyo.
– Iwusizo kakhulu uma ividiyo ithunyelwa kufayela elijwayelekile futhi idlalwa kunoma iyiphi idivayisi.
Okubi: Uma umbhalo umboza izinto ezibalulekile (njengobuso noma amapuleti elayisensi), kungaphazamisa. Ngakho-ke, ukubeka umbhalo ngokucophelela kanye nosayizi kubalulekile.
Isitembu sesikhathi njengeMetadata
– Ngokuvamile akubonakali esikrinini.
- Isetshenziselwa ukusesha, ukufaka ohlwini, kanye nokudlala kusofthiwe ethile.
– “Kuhle” kakhulu, kodwa kuncike kumdlali noma kuhlelo lokusebenza olusekelayo.
Okungcono kakhulu, uhlelo lusekela kokubili: ukunqwabelanisa kobufakazi obubonakalayo kanye nemethadatha yokusesha okusheshayo.
Izinkinga Ezivamile Ngezitembu Zesikhathi ze-CCTV
1. Iwashi licimile (alinembile)
Izimbangela zifaka phakathi ukungasebenzisi i-NTP, ibhethri le-CMOS elibuthakathaka (kwamanye ama-DVR), ukucima kukagesi njalo, noma izilungiselelo ezingalungile ezenziwe ngesandla. Imiphumela imbi kakhulu: ukurekhoda kuba nzima ukukusebenzisa njengezinkomba zesikhathi futhi kungaphakamisa ukungabaza ngesikhathi sokuhlolwa.
2. Izinguquko Zesikhathi Ngemva Kwesigameko
Uma umphathi eshintsha iwashi ledivayisi ngemva kwesigameko, umugqa wesikhathi ungaba yinto edidayo. Ngisho noma inhloso iwukulungisa isimo nje, lolu shintsho lungaphakamisa imibuzo mayelana nobuqotho bobufakazi. Ngakho-ke, izinguquko zokucushwa kufanele zibhalwe phansi futhi zisetshenziswe ngokwezinqubo ezicacile.
3. Indawo Yesikhathi Engalungile
Amaphutha endawo yesikhathi abangela ukuthi ukuqoshwa kubonakale sengathi "kuphambili" noma "kubuyela emuva" ngamahora amaningana. Lokhu kuvame ukwenzeka kumadivayisi asebenzisa izilungiselelo ezizenzakalelayo zasefekthri noma asekelwe endaweni yesikhathi yezwe elihlukile.
4. Ifomethi Yosuku Oludidayo
Ifomethi ye-DD/MM/YYYY uma iqhathaniswa ne-MM/DD/YYYY ivame ukuholela ekuchazeni kabi, ikakhulukazi uma usuku nenyanga zombili zi-<=12. Kumasistimu anabasebenzisi abaningi, ifomethi ye-ISO (YYYY-MM-DD) ivame ukuvikeleka kakhulu. Izindlela Ezinhle Zokusebenzisa Izitembu Zesikhathi Ezinembile 1. Nika amandla i-NTP ku-DVR/NVR nakuwo wonke amakhamera e-IP, bese ucacisa iseva ye-NTP ethembekile. 2. Setha indawo yesikhathi ibe yinye (isb., i-WIB/GMT+7) bese uqinisekisa ukuthi amadivayisi alandela leso silungiselelo. 3. Khiya ukufinyelela kokucushwa: khawulela ukuthi ubani ongashintsha isikhathi nezilungiselelo zesistimu. 4. Sebenzisa i-UPS yamadivayisi e-DVR/NVR kanye nenethiwekhi ukuvimbela isikhathi ukuthi singaphinde sisethwe ngesikhathi sokuphela kukagesi. 5. Ukuhlolwa okuvamile: hlola ukunemba kwesikhathi okungenani kanye ngenyanga, ikakhulukazi ezindaweni ezinokucima okuvamile noma ukuxhumana kwe-inthanethi okungazinzile. 6. Beka izimbozo ukuze zingambozi izindawo ezibalulekile (iminyango, abakhokhi, ubuso, amapuleti elayisense). 7. Gcina ilogi yokushintsha: amadivayisi amahle aqopha ukuthi ukucushwa kwashintshwa nini nokuthi ubani. Lokhu kusiza ukugcina ukwethembeka kokuqoshwa. Izitembu zesikhathi kumongo wezomthetho nowokuthobela imithetho Kwezinye izimo, izithombe ze-CCTV zisetshenziselwa ukubika kwangaphakathi, izimangalo zomshuwalense, noma izinqubo zomthetho. Izitembu zesikhathi ezihambisanayo nezithembekile zisiza ukukhombisa ukuthi izithombe zinomongo wesikhathi ocacile. Ngenkathi izitembu zesikhathi zingeyona yodwa into enquma ubuqiniso bobufakazi, ukungabikho kwazo noma ukungalungi kungenza buthaka isikhundla somuntu oletha izithombe njengobufakazi obusekelayo. Ngaphezu kwalokho, ezinkampanini ezinezinqubomgomo zokuphepha kwedatha, ukugxivizwa kwesikhathi kuhlobene nokuthobela imithetho: lapho idatha iqoshwa khona, ukuthi igcinwa isikhathi esingakanani, nokuthi isuswa nini. Konke lokhu kuncike esikhathini esinembile sesistimu. Isiphetho Ukugxivizwa kwesikhathi okuzenzakalelayo kuzithombe ze-CCTV kuyisici esibalulekile sesistimu yokuphepha. Kusiza ukuqinisekisa ukuthi izithombe azigcini nje ngokubhala okubonakalayo, kodwa futhi nokurekhoda kokulandelana kwesikhathi okusiza ukusesha, ukuvumelanisa, uphenyo, kanye nokuhlola. Kodwa-ke, lezi zinzuzo zikhuliswa kuphela uma izitembu zesikhathi zigcinwa ngokunembile ngokuvumelanisa kwe-NTP, izilungiselelo zesikhathi ezifanele, kanye nezinqubo zokuphatha ezihlelekile. Uma ufaka noma uphatha i-CCTV, qiniseka ukuthi isici sesitembu sesikhathi asigcini nje ngokuthi "sivuliwe," kodwa futhi sinembile, siyahambisana, futhi siyaqinisekiswa. Ngoba lapho kwenzeka isigameko, imininingwane emincane efana nesikhathi nosuku ivame ukuba yizinto ezibalulekile ekwenzeni isinqumo esifanele.
