Tam sim no peb tuaj yeem pom kev sib xyaw ua ke ntawm lub qhov rooj ntawm yuav luag txhua qhov nkag. Ntawm lawv lub hauv paus, lawv tsis yog ib puas feem pua kev ntseeg tau, tab sis tseem pab ua kom lub qhov nkag huv si thiab tiv thaiv cov neeg sab nrauv nkag mus.
Kev sib txuas xauv sib txawv ntawm txoj cai ntawm kev ua haujlwm, khoom siv thiab, raws li, tus nqi. Lawv yog mounted thiab built-in, mechanical thiab electronics. Txhawm rau qhib qhov sib xyaw ua ke, nws yog ib qho tsim nyog yuav tsum nkag mus rau hauv qee txoj kev (feem ntau siv cov keyboard) cov lej sib txuas khaws cia hauv qhov zais zais ntawm lub xauv. Xws li xauv muaj ob qho tib si pluses thiab minuses nyob rau hauv kev sib piv nrog cov pa sawv daws yuav. Ntawm qhov zoo, ib tus tuaj yeem tawm qhov tsis muaj
koj cov yuam sij uas nyiam ploj ntawm lub sijhawm tsis tsim nyog tshaj plaws. Yog tias cov txheeb ze lossis phooj ywg tuaj xyuas koj, tsis tas yuav ua dua. Tsis tas li ntawd, cov pluses suav nrog kev muaj peev xwm hloov cov cai yog tias muaj kev xav tias tus lej qub tau dhau los ua neeg paub txog. Lub downside yog tias tus lej tuaj yeem tsis nco qab lossis nws tuaj yeem raug soj ntsuam los ntawm tus neeg sab nraud. Undoubtedly, qhov tsis zoo muaj xws li qhov tseeb tias nrog nquag ntaus ntawv ntawm tib txoj cai, cov nyees khawm tau sau dua.tus lej, thiab tus neeg tawm tsam tuaj yeem yooj yim siv qhov zoo ntawm qhov no. Vim li no
th codes yuav tsum tau hloov ntau li ntau tau.
Cov khoom siv sib xyaw ua ke yog feem ntau pom ntawm lub qhov rooj ntawm cov tsev. Qhov no yog vim lawv cov qauv tsim yooj yim thiab muaj kev ntseeg siab. Cov xauv no yog ua los ntawm cov hlau zoo. Tsis zoo li cov khoom siv hluav taws xob, lawv tsis nyob ntawm hluav taws xob, thiab tseem tsis muaj cov txheej txheem uas tuaj yeem tawg. Sab hauv muaj cov thooj voos kheej kheej, uas, tom qab dialing code, kab nyob rau hauv ib tug tej yam ib ntus, thiab lub qhov rooj qhib. Tom qab qhib lub qhov rooj, nws txaus tsuas yog kaw nws tom qab koj, xws li lub xauv yuav kaw cia li (yog tias koj muaj lub kaw lus kaw, koj tsis tas yuav ua qhov no, lub qhov rooj yuav kaw nws tus kheej).
Lwm yam yog cov khoom siv hluav taws xob ua ke. Lawv kuj tau siv rau ntawm lub tsev qhov rooj nrog rau cov neeg kho tshuab, tab sis yog kim dua vim siv cov cuab yeej siv niaj hnub microprocessor. Tsis zoo li cov khoom siv sib xyaw ua ke, hauv cov khoom siv hluav taws xob cov txheej txheem yog khaws cia hauv lub cim xeeb ntawm cov khoom siv hluav taws xob. Lawv kuj tsis muaj lub tog raj kheej loj thiab cov nyees khawm. Lawv tau hloov los ntawm lub vaj huam sib luag me me thiab cov keyboard. Lawv raug suav tias yog qib siab dua, vim tias lawv muaj ntau yam ntxiv, xws li backlighting keyboard lossis qhib qhov rooj nrog daim npav tshwj xeeb, tab sis kuj tseem muaj ob peb nuances los xav txog nrog lawv. Ua ntej, xws li lub tsev fuabtais yuav tsum tau tiv thaiv huab cua (tsis muaj qhov yuav tsum tau uadej yuav tsum nkag rau hauv), thiab qhov thib ob, rau kev ua haujlwm ib txwm, nws
xav tau lub zog tas li.
Ib hom kev sib xyaw ua ke yog lub xauv xauv. Nws yog ib qho yooj yim-saib padlock uas muaj ob peb lub log (feem ntau yog 3-4) rau kev hu rau tus lej tsim nyog. Vim li no, nws yog qhov txhim khu kev qha ntau dua li cov pa ntsuas phoo, tab sis tseem tsis tshua muaj kev ntseeg siab tshaj li qhov tsim-hauv ib qho, vim tias cov hlau shackle tuaj yeem raug txiav tawm. Feem ntau, cov xauv no yog siv los kaw cov chaw nres tsheb, cov txee dai khaub ncaws lossis chav siv hluav taws xob.
