Kwadalwa ngo 10.25
Njengoba izixeko zikhula futhi izixeko zifuna ukusebenza kahle, ukuphepha, nokuhlala isikhathi eside, imizamo yokwakha amadolobha akhanyayo seye yaba yinto ebalulekile emhlabeni jikelele. Kusukela ekuphathweni kwemigwaqo kuya kokuphepha komphakathi, izixazululo ezisekelwe kudatha ziguqula izindawo zasemadolobheni—futhi enhliziyweni yezinhlelo eziningi zalezizixazululo kukhona ingxenye ebalulekile, kodwa evame ukungabhekwa:amamojula ekhamera yokubona ebusuku. Lezi zisetshenziswa ezincane, ezinamandla zixhumanisa isikhala phakathi kokusebenza kosuku nangesikhathi sobusuku, ziqinisekisa ukuthi izakhiwo zedolobha ezihlakaniphile zisebenza kahle 24/7. Kulolu hlu, sizohlola ukuthi ama-modules wekhamera yokubona ebusuku akha kanjani ukuthuthukiswa kwedolobha elihlakaniphile, ubuchwepheshe bawo obubalulekile, izicelo zangempela, nokuthi yini okufanele uyicabangele uma uwahlanganisa ezinhlelweni zasemadolobheni.
Ukuqonda Amamojula Ezikhamuzi Zokubona NgeNhliziyo: Ngaphezu Kokuqapha Okuyisisekelo
Ngokuyinhloko, amamojula wekhamera yokubona ebusuku ayizinhlelo zokuthwebula ezikhethekile eziklanyelwe ukuthwebula izithombe ezicacile ezimeni zokukhanya okuphansi noma emnyama ngokuphelele. Ngokwehlukile kumakhamera ajwayelekile asebenzisa ukukhanya okuboniswayo, lawa mamojula asebenzisa ubuchwepheshe obuphambili ukuze athole futhi akhuphule ukukhanya okukhona noma akhe ukukhanya kwawo. Izinhlobo ezimbili eziyinhloko ezisebenza kumamojula wekhamera yokubona ebusuku yanamuhla ezindaweni zokuhlala ezihlakaniphile ziyi-infrared (IR) esebenzayo kanye nokuthwebula okuphansi kokukhanya okungasebenzi.
Active IR modules work by emitting infrared light (invisible to the human eye) via built-in illuminators and capturing the reflected light with a sensor. This technology is cost-effective and reliable, making it ideal for short-to-mid-range applications like street-level surveillance. Passive low-light modules, on the other hand, amplify faint ambient light (such as moonlight or streetlights) using high-sensitivity sensors like back-illuminated CMOS (BI-CMOS) or charge-coupled devices (CCDs). For extreme low-light conditions, some modules combine both technologies, offering versatility for diverse urban environments.
Lokho okwehlukanisa amamojula okubona ebusuku agxile emadolobheni akuhlobene nokuhlanganiswa kwawo nezinye izobuchwepheshe: ngokuvamile zinekhono lokucubungula edwaleni ukuze zisebenze idatha endaweni (kwehlisa isikhathi sokulinda), ukuhambisana nezinhlelo ze-IoT ukuze kube nokwabelana ngedatha okungaphazamiseki, kanye nezinsiza eziphezulu zokuxilonga (ukuze kube ngu-4K) ukuze ziqoqe imininingwane esebenziseka—kusukela kumaphasiwedi kuya ezicini zobuso—ngisho nasemnyama.
Izinhlelo Eziyinhloko Ku-Smart City Ecosystems
Izikhangiso zezikhamuzi zokubona ebusuku azihambisani nazo zonke; ukusebenza kwazo kudlula ezindaweni eziningi zedolobha ezihlakaniphile, ngayinye ibhekana nezinselelo ezihlukile zedolobha. Nansi eminye yemisebenzi ethinta kakhulu:
1. Ukuphepha Komphakathi Nokuvikela Izenzo Zobugovu
Amadolobha emhlabeni jikelele abhekene nengcindezi yokunciphisa izinga lobugebengu ngenkathi kuncishiswa isidingo sokuba nezinsizakalo zabantu ezihlala zikhona. Imodyuli yekhamera yokubona ebusuku ivumela ukuqapha okungapheli ezindaweni ezisemathubeni aphezulu—izindawo zokupaka, izindlela ezincane, nezikhungo zokuhamba zomphakathi—ngaphandle kokuphazamisa abantu abahlala khona ngezibani ez bright. Emkhankasweni we-Smart Nation eSingapore, amakhamera anama-IR ezindaweni zokuhlala asize ukunciphisa ubugebengu obuncane obubangelwa ubusuku ngo-37% kusukela ngo-2020, ngokusho kweSingapore Police Force. Le modyuli ihlanganisa nezinsiza ezisebenza nge-AI ukuze kutholakale ukuziphatha okungajwayelekile (isb., othile ophumile eduze kwezinsiza ezibalulekile) futhi ithumele izaziso zangesikhathi sangempela kumaphoyisa, ivumela ukungenelela okuphumelelayo.
2. Ukuphathwa Kwezimoto Okuhlakaniphile
Traffic congestion and accidents peak during dawn, dusk, and nighttime hours when visibility is poor. Night vision camera modules mounted on traffic lights, highway overpasses, and street poles provide clear footage of vehicle and pedestrian movement. In Barcelona’s smart traffic system, these modules track lane violations, detect jaywalkers, and monitor traffic flow after dark. The data is fed into the city’s traffic management platform, which adjusts signal timings and sends hazard alerts to drivers via navigation apps. A 2022 study by the city found that nighttime traffic accidents decreased by 29% following the deployment of these modules.
3. Ukuhlola Izinsiza Eziyinhloko
Amadolobha akh smart axhomeke ezakhiweni ezifana nezinhlelo zamandla, izitshalo zokwelapha amanzi, nezinsika zokuxhumana—izimpahla ezidinga ukuqapha okungama-24/7 ukuze kugwenywe isikhathi sokungasebenzi noma ukuhlaselwa. Imodyuli yekhamera yokubona ebusuku enekhono le-IR elide (kuze kube ngamamitha angama-100) ifakwe ezindaweni ezinjalo ukuze kutholakale ukuhlaselwa, ukuwohloka kwemishini (isb. ipayipi eliphumayo noma i-transformer efudumele kakhulu), noma ukuhlekwa. Eprojekthini yeSmart City yaseDubai, imodyuli ezitshalo zokuhlunga amanzi ziye zathola izimpawu zokuqala zokwehluleka kwemishini kathathu ngokushesha kunabahloli bomuntu, kugcina idolobha imali engama-$2 million yokulungisa minyaka yonke.
4. Ukuphendula Okuphuthumayo
Ngesikhathi seziqhamo zemvelo (isb. izikhukhula, umhlaba ophukile) noma izinkinga ezenziwe ngabantu (isb. umlilo), ukubonakala kuvame ukuphazamiseka kakhulu, okwenza kube nzima imizamo yokusiza. Amamojula wekhamera yokubona ebusuku afakwe kumadroni nakumathuluzi okuphuthumayo avumela abaphenduli bokuqala ukuthi bahambe ezindaweni ezithintekile, bathole abasindile, futhi bahlaziye umonakalo ngemuva kokukhanya. ETokyo, edlula ezikhukhulweni ezivamile, amadroni anamamojula okukhanya okuphansi asize amaqembu okusiza ukuthola abantu ab trapped ezindaweni ezikhukhulwe ngesikhathi sezikhukhula zobusuku, kunciphisa isikhathi sokuphendula ngama-50%.
Izinto Eziyinhloko Okufanele Zicatshangelwe Ekuxhumaneni
Ngenkathi amamojula wekhamera yokubona ebusuku ehlangabezana nenani elikhulu, ukuhlanganiswa kwawo ngempumelelo ezinhlelweni zedolobha ezihlakaniphile kudinga ukuhlela ngokucophelela. Nansi imingcele ebalulekile abahleli bedolobha namathimba wezobuchwepheshe kumele babhekane nayo:
Ukuxazulula kanye neKhwalithi yeMifanekiso
Ukuze idatha ibe nezenzo, amamojula kumele abambe izithombe ezicacile, ezinemininingwane. Bheka amamojula anokunciphisa okungenani kwe-1080p (i-4K iyathandwa ezinhlelweni ezifana nokuhlonza amaphuzu ezinombolo) kanye nezinga eliphansi lokukh noise—elilinganiswa ngokuqhathaniswa kwesignali nokukh noise (SNR). I-SNR ephezulu (ngaphezulu kwe-50dB) iqinisekisa ukuthi izithombe zihlala zicacile ngisho nasekukhanyeni okuphansi kakhulu.
Uhlanga kanye Nokukhanya
Ibanga le-IR elidingekayo lincike kokusetshenziswa: ukubhekwa kwezitaladi kungase kudinge kuphela amamitha angama-20–30, kanti ukuqapha izakhiwo kudinga amamitha angama-50+. Khetha ama-modules anama-illuminators alungisekayo ukuze ugweme ukuveza izinto eziseduze kakhulu (okungase kube nomthelela ekucaciseni) noma ukuchitha amandla ebangeni elingadingekile.
Amandla Okusebenza
Izinsiza zedolobha ezihlakaniphile zivame ukufakwa ezindaweni ezikude ezinomthamo ophansi wamandla (isb., izinsika zomgwaqo ngaphandle kwezikhala zamandla eziseduze). Khetha ama-modules anokusetshenziswa kwamandla okuphansi (okungcono ngaphansi kwe-5W) angasebenza kumaphaneli elanga noma ezinsizeni zamabhethri. Lokhu akunciphisi kuphela izindleko zokusebenza kodwa futhi kusekela imigomo yokusimama yedolobha.
Ukuhambisana kwe-IoT
Amamojula kumele ahlanganiswe ne-ecosystem ye-IoT esivele ikhona edolobheni (isb., LoRaWAN, 5G, noma amanethiwekhi e-Wi-Fi 6) ukuze wabelane ngedatha nezinkundla eziphakathi. Qinisekisa ukuthi amamojula asekelwa ama-protocol avulekile (njenge-MQTT) ukuze kube lula ukuhlanganiswa futhi ugweme ukuvalelwa kumthengisi.
Idatha Ubumfihlo kanye Nokuphepha
Amakhamera, ikakhulukazi lawo anokubona ebusuku, akhuphula ukukhathazeka ngokuqinisekiswa. Izixeko kumele zilandela imithetho efana ne-GDPR ye-EU noma i-CCPA yaseCalifornia ngokwenza idatha ebucayi ingaziwa (isb. ukungacacisi ubuso ezindaweni zomphakathi) nokuvikela amanethiwekhi amakhamera ekuphulweni. Khetha ama-modules anokufihla okwakhiwe ngaphakathi (AES-256) kanye nezibuyekezo ezijwayelekile ze-firmware ukuze unciphise izingozi.
Ikusasa Lezinhlelo Zokubona NgeNhliziyo Emadolobheni Ahlakaniphile
Njengoba ubuchwepheshe buqhubeka, amamojula wekhamera yokubona ebusuku ayanda ukuthuthuka, abe mncane, futhi ahlanganiswe nezinsiza eziphumelelayo zedolobha ezihlakaniphile. Nansi imikhuba okufanele uyibheke:
AI kanye neMishini Yokufunda Ukuhlanganiswa
Izinhlelo zesikhathi esizayo zizohlanganisa ukubona ebusuku ne-AI esebenzisa idivayisi ukuze zenze ukuhlaziywa kwesikhathi sangempela—isb., ukuhlukanisa phakathi kwesilwane esingaziwa nomuntu ongenele, noma ukuthola imoto enerejista esiphelelwe yisikhathi. Lokhu kunciphisa isidingo sokucubungula efwini, kwehlisa isikhathi sokuphendula nezindleko ze-bandwidth.
Miniaturization and Discretion
Amamojula ayancipha ngosayizi, okwenza kube lula ukuwafaka ezindaweni ezihlukene (isb., ngaphakathi kwezibani zomgwaqo noma izimpawu zomgwaqo) ngaphandle kokuphazamisa ubuhle bezindawo zasemadolobheni. Abakhiqizi abanye baphinde bathuthukisa amamojula ahlanganiswe nezindonga zokwakha, bebhekana nezinkinga zokuthi “ukubhekwa kancane kancane.”
Imaging ye-Multispectral
Ngaphandle kokukhanya okubonakalayo nokukhanya kwe-IR, amamojula alandelayo azothatha idatha ezindaweni eziningi (isb. ukwakheka kokushisa). Lokhu kuzovumela izinhlelo ezintsha, ezifana nokuthola uku leak kwegesi (ngokusebenzisa izimpawu zokushisa) noma ukuqapha ikhwalithi yomoya ebusuku—kwandisa indima yabo ngaphezu kokubhekwa ukuze kube nokuhlola kwemvelo.
Ukuthuthukiswa Kwe-Edge Computing
Ngenkathi kukhula i-5G, ama-modules azokwazi обработать idatha eningi endaweni, avumele ukwenza izinqumo ngokushesha. Isibonelo, i-module endaweni yokwakha ingakwazi ukuthola ukuphulwa kwemithetho yokuphepha (isb., umsebenzisi ongena nekhanda eliqinile) ebusuku futhi iqhube i-alamu endaweni ngaphakathi kwemizuzwana, ngaphandle kokulinda idatha ifike kuseva enkulu.
Isiphetho
Izikhangiso zezimoto zokubona ebusuku azisagcini nje ngokuba “izengezo” kumasistimu edolobha ehlakaniphile—zizinto ezisemqoka ezivumela ukusebenza okungama-24/7, zandise ukuphepha, futhi zivule amazinga amasha okusebenza kahle. Kusukela ekuvimbeleni ubugebengu kuya ekuphatheni ithrafikhi nasekugadweni kwezinsiza, umthelela wazo uyabonakala futhi ubanzi. Njengoba amadolobha eqhubeka nokutshala imali kubuchwepheshe obuhlakaniphile, isidingo sezikhangiso zokubona ebusuku ezisezingeni eliphezulu, ezisebenza kahle ngamandla, futhi ezihambisana nezimfanelo zobumfihlo sizokhula kuphela.
Kubahlaziyi bezinhlelo zedolobha, okubalulekile ukuhlela ukusebenza kahle ngokucacile: ukukhetha ama-modules ahlangabezana nezidingo zobuchwepheshe ngenkathi ebhekana nezinkathazo zomphakathi mayelana nokuvikeleka. Kubahlinzeki bezobuchwepheshe, ithuba likhona ekwakheni izixazululo ezihlanganisa kahle nezinhlelo ezikhona futhi zishintsha ukuze zifanele izitayela ezivela njenge-AI ne-5G.
Ekugcineni, umgomo wokuthuthukiswa kwemizi ehlakaniphile uwukwakha izindawo zasemadolobheni eziphephile, ezihlala kahle—futhi amamojula kamakhamera wokubona ebusuku asiza ukwenza lo mgomo ube yiqiniso, ngosuku nasentambama.
