Kwadalwa ngo 05.26
Abantu abaningi bajwayelane namakhamera e-USB njengama-webcam asekhaya noma izinto zokuphepha zasekhaya zasendlini. Kodwa-ke, amakhamera e-USB asezingeni lezimboni seziyindlela esebenzayo kumakhamera e-IP abizayo, amakhamera e-PoE, kanye nemishini yokubona ithrafikhi ezinikezelwe ukuze kube nokuqapha izimoto zesimanje. Lawa makhamera ahlinzeka ngokuthwebula izithombe ezisezingeni eliphezulu, ukuhlanganiswa okulula, kanye nezindleko zokuba nazo (TCO) eziphansi emaqenjini ezokuthutha omkhandlu, iminyango yezokuthutha, kanye nabakhi bezingqalasizinda ezihlakaniphile.
Ukuqapha izimoto kuyisisekelo sokuhamba okuphephile, okuphumelelayo emadolobheni. Kusekela ukuhlaziywa kwesivinini sezimoto ngesikhathi sangempela, ukuphoqelela imithetho yemigwaqo (red-light enforcement), ukubona izinombolo zezimoto (LPR/ANPR), ukubona abahamba ngezinyawo, ukulawula ukuminyana kwezimoto kanye nempendulo ezingozini. Iminyaka edlule, amadolobha ayethembele ezinhlelweni zamakhamera ezimoto ezibizayo, ezidinga izintambo eziyinkimbinkimbi, ihadiwe eyikhethekile kanye nokugcinwa okubizayo. Namuhla, amakhamera e-USB okuqapha izimoto enza ukufakwa kube lula, anciphise izindleko ngama-70% futhi agcine ukusebenza kumazinga ochwepheshe.
Lo mhlahlandlela uchaza ukuthi kungani amakhamera e-USB asezingeni lezimboni alungele ukuqapha izimoto, ukuthi ungakhetha kanjani imodeli efanele, izimo zokusebenzisa empeleni, namathiphu okuhlanganisa amanethiwekhi ezimoto ezihlakaniphile. Noma ngabe wakha isiqaphi esincane sendawo noma uhlelo lokuqapha izimoto lonke idolobha, amakhamera e-USB asiza ukukhulisa ukusebenza kahle nokunciphisa izindleko zesikhathi eside.
Amaphutha Ezinhlelo Zokujwayelekile Zamakhamera Ezimoto (Ahlanganiswa Amakhamera E-USB Ezingeni Lezimboni)
Ihadi ye-traffic monitoring hardware idala izinkinga ezihambisanayo emadolobheni nakubakhi. Amakhamera e-USB embonini axazulula zonke izinkinga ezisemqoka ngenkathi ehambisana noma idlula ukusebenza kwamakhamera ajwayelekile.
1. Izindleko Eziphansi Zokuqala Nezikhathi Ezingamashumi
