Kev pab kho tshuaj nrog rau kev ua lag luam, cov tools tshiab dhiaj muaj los pab ua siab thiab ua rau qhov kev tsim kho khoom zoo dua. Ib qho khoom uas dhiaj ua kom cov khoom lag luam zoo dua yog cov ntaub ntawv saib xyuas cov ntaub ntawv.
Kev saib xyuas cov ntaub ntawv saum npoo cov khoom lag luam yog qhov chaw ua haujlwm tshwj xeeb uas tuaj yeem xyuas kom paub tseeb tias cov ntaub ntawv saum npoo cov khoom lag luam yog tseeb lossis tsis tseeb thiab nyob rau qhov chaw sib xws. Cov camera no tuaj yeem saib cov ntaub ntawv saum npoo cov khoom lag luam nrog qhov xwm thiab soj ntsuam nrog cov lej kom paub tseeb tias lawv tau ua raws li cov lus qhia. Qhov no pab cov chaw tsim khoom kom tsis txhob ua tiav thiab pab kom paub tseeb tias cov khoom lag luam ntawm lawv zoo ua ntej xa tawm.
Kev siv tus neeg saib xyuas ntawv qhia tuaj yeem pab cov neeg ua lag luam tsim kho qhov lag luam sai thiab yooj yim rau kev txawj nkawm. Lawv cov neeg no tuaj yeem saib xyuas cov ntawv qhia rau cov khoom lag luam thaum lawv huv mus rau hauv qhov tsheb ntim khoom, uas yog qhov ua rau sai dua li kev saib xyuas lub zog. Qhov no ua rau cov neeg ua lag luam muaj peev xwm tsim khoom thiab xa mus rau qhov chaw muag khoom sai dua, kom cov neeg ua lag luam tuaj yeem tiv thaiv tau qhov xwm yeem txaus si thiab cov neeg ua lag luam tuaj yeem nce mus rau hauv qhov kev lag luam.
Lawv feem ntau yog qhov tseem ceeb heev thaum lawv saib xyuas cov ntawv qhia. Cov neeg no muaj qhov kev paub txog kev saib xyuas cov ntawv qhia thiab so kom zoo li cov kev cai uas tau teev tseg ua ntej. Txhua qhov yuam kev yooj yim kuj tau txais so thiab ua ntej thaum cov khoom lag luam tau xa tawm ntawm qhov chaw tsim khoom. Qhov no pab cov neeg ua lag luam tiv thaiv qhov zog zoo heev ntawm cov khoom lag luam thiab qhov siab rau cov neeg siv khoom.
Qhov no yog ib qho uas ua rau qhov kev saib xyuas cov ntaub ntawv hluav taws xob zoo heev: lawv cia siab txog sijhawm thiab txo qhov tsis raug hauv kev teeb tsa. Cov ntaub ntawv saib xyuas no tuaj yeem ua haujlwm tag nrho lub sijhawm, tsis txhob yuav tsum teeb tsa cov ntaub ntawv hluav taws. Nws kuj tso ceeb ntawm cov neeg ua lag luam kom pom cov qat ua ntej nyob rau hauv kev tsim kho, cia siab sijhawm thiab lwm yam khoom nrog rau hauv qab.
Tom qab ntawm kev teeb tsa cov ntaub ntawv zoo thiab nyob rau qhov chaw tsim nyog, cov ntaub ntawv saib xyuas cov ntaub ntawv tuaj yeem pab daws cov khoom tsim thiab kev lag luam. Cov ntaub ntawv no tuaj yeem mus saib cov ntaub ntawv zoo li qhov zoo ntawm xim thiab qhov zoo ntawm kev sau rau kev ua siab tias cov khoom lag luam zoo heev nyob rau hauv qhov chaw tsim khoom. Qhov kev nco ntsoov no tuaj yeem ua rau qhov sib txawv uas pab cov neeg ua lag luam kom zoo dua thiab tau neeg ua lag luam ntau dua.
