?? CCTV lub koob yees duab: ua haujlwm cov ntsiab cai thiab kev paub cuam tshuam

Lub hauv paus rau phau ntawv

CCTV (kaw - Circuit TV) yog daim vis dis aus saib xyuas kom dav rau kev saib xyuas kev ruaj ntseg, kev lag luam, thiab ib cheeb tsam kev lag luam. Tsis zoo tshaj tawm TV TV, CCTV cov paib qhia hauv lub voj kaw, siv tau tsuas yog rau cov neeg pom kev tso cai.

1. Yuav ua li cas CCTV cov koob yees duab ua haujlwm

1.1 Cheebtsam ntawm CCTV system

Ib qho cctv system suav nrog cov tseem ceeb hauv qab no:

• Lub koob thaij duab - Cov lus pom tau pom cov ntaub ntawv.

• Daim iab - Tsom cov teeb rau ntawm lub sensor.

• Cov Duab Sensor - Hloov lub teeb rau hauv lub teeb liab hluav taws xob (CCD lossis CMOS).

• Yees duab processor - Hloov pauv thiab cov txheej txheem duab kos npe.

• Kis tau sib kis - Hloov cov ntaub ntawv video (xaim lossis wireless).

• Cov Ntaubntawv thiab cov khoom siv cia - DVR (DESAL Video Recorder), NVR (Network Video Recorder), lossis Huab Cia COOL.

• Saib Xyuas - Vacthabnes lav cov tiag tiag - lub sijhawm lossis kaw cov duab.

1.2 kauj ruam - los ntawm - Nqis Ua Haujlwm Txheej Txheem

1. Duab ntes:
   Teeb hla dhau lub koob yees duab lens thiab ntaus cov duab sensor (CCD lossis CMOS), hloov kho qhov muag kho qhov muag rau hauv cov cim hluav taws xob.

2. Teebcim Ua:
   Lub koob yees duab sab hauv converts converts raw cim rau hauv kev pom video ntws.

3. Kev tiv tauj:

   • Lub tshuab analog Hloov cov yeeb yaj kiab ntawm coaxial clesles rau DVR.

   • IP - cov tshuab Hloov cov ntaub ntawv ntawm Ethernet lossis wireless network rau ib qho NVR lossis huab platform.

4. Nkauj kaw:
   Daim duab footage yog khaws cia rau ntawm cov tawv ntoo hauv zos, SD card, lossis chaw taws teeb / huab servers.

5. Xyuas:
   Daim duab yog saib hauv lub sijhawm lossis rov ua haujlwm ntawm cov khoom sib txuas xws li saib xyuas xws li cov saib, PCs, lossis xov tooj ntawm tes.

2. Hom CCTV cov koob yees duab

3. Cov Duab Sensor Technologies

• CCD (them - Coupled ntaus ntawv): Paub rau cov duab zoo tshaj plaws; ntau dua tus nqi thiab fais fab siv.

• CMOS (multementary hlau - olide - semiconductor): Muaj nqis pheej yig thiab lub zog - muaj peev xwm; pheej txhim kho hauv qhov zoo.

4. Cov yam ntxwv tseem ceeb ntawm kev siv cctv niaj hnub

• Siab - Txhais (HD / 4K) Kev daws teeb meem Video

• Lub zeem muag hmo ntuj ntawm infrared (ir) thev naus laus zis

• Kev kuaj cov lus tsa suab thiab cov lus ceeb toom

• Ob - Txoj Kev Audio Kev Sib Txuas Lus

• Huab - Raws Chaw Cia Khoom thiab Chaw Nkag Mus Nkag

• AI - Powered Video Analytics thiab Kev Paub Zoo

• Kev koom ua ke nrog cov tshuab ntse thiab iot

5. Kev Xa Khoom

• Coaxial cable (RG59): Kev tsoos analog video kis

• Ethernet cable (Cat5E / Cat6): Txhawb lub zog tshaj ethernet (POE) rau IP cov koob yees duab

• WI - FI lossis RF kis: Ua kom muaj kev sib txuas wireless

• Fiber ntau Optics: Zoo rau kev ncua ntev - nrug, siab - bandwidth cov ntaub ntawv kis

6. Cov ntawv thov CCTV

• Thaj chaw thiab cov khoom lag luam ruaj ntseg

• Khw muag khoom tub sab nyiag

• Kev lag luam kev nyab xeeb thiab ua haujlwm

• Cov Tsheb thiab Tsheb Thauj

• Tuam txhab nyiaj thiab cov tuam txhab nyiaj txiag

• Pej xeem chaw thiab tub ceev xwm

7. Kev txiav txim siab thiab kev coj ua

• Ua raws li kev ceev ntiag tug

• Cov ntaub ntawv kev ruaj ntseg thiab encryption

• Kev Tso Cai Siv thiab Ceeb Toom

• Kev siv kev siv hauv zej zog thiab ntiag tug

Cov koom haum yuav tsum ua kom ntseeg tau tias muaj kev cai lij choj rau cheeb tsam cov kev cai lij choj ntsig txog kev sau cov ntaub ntawv, cia, thiab kev soj ntsuam, thiab kev soj ntsuam, thiab kev soj ntsuam cov kev soj ntsuam.

8. Tawm thev naus laus zis: Ai sib xyaw

Kev sib koom ua ke ntawm kev txawj ntse nrog CCTV thev naus laus zis siv:

• Kev Txiav Txim Siab Txiav Txim Siab

• Yam khoom thiab lub ntsej muag paub

• Kev Coj Tus Qauv Cim Kev Ntsuam Xyuas

• Tiag tiag - Sijhawm Anomaly ceeb toom

• Neeg coob thiab tswj hwm

AI hloov CCTV los ntawm cov cuab yeej soj ntsuam passive rau hauv kev daws teeb meem kev ruaj ntseg.

CCTV Technology ua lub luag haujlwm tseem ceeb hauv kev soj ntsuam niaj hnub los ntawm kev muab cov peev xwm saib xyuas tiag tiag, thiab kev txheeb xyuas cov peev xwm, thiab kev txheeb xyuas cov peev xwm, thiab kev txheeb xyuas qhov tseeb. Raws li thev naus laus zis hloov zuj zus, AI thiab IOT kev sib xyaw ua ke ntawm dab tsi CCTV tuaj yeem ua tiav, txhim kho kev nyab xeeb, kev nyab xeeb, thiab ua haujlwm zoo.
