Kakaretso ea tsamaiso ea ho shebella video

Matsatsing ana, marang-rang a ho shebella livideo a ntse a tsebahala le ho feta, 'me ho na le litharollo tse ngata tsa ho aha lits'ebetso tsa ho shebella livideo.Har'a tsona, tlhahlobo ea CCTV le tlhahlobo ea kh'amera ea IP ke litharollo tse atileng haholo.

Sistimi ea ho shebella thelevishene e koetsoeng (CCTV)
Ka mokhoa o tloaelehileng oa ho shebella thelevishene o koetsoeng, khamera ea analog e tsitsitseng (CCTV) e hokahane le sesebelisoa sa polokelo (joaloka sehatisi sa video sa cassette VCR kapa digital hard disk video recorder DVR) ka mohala oa coaxial.Haeba kh'amera e le kh'amera ea PTZ (e ts'ehetsa ho potoloha, ho sekamela le ho atametsa), ho tlameha ho eketsoa molaoli oa tlatsetso oa PTZ.

Sistimi ea ho shebella video ea marang-rang ea IP
Ka marang-rang a tloaelehileng a marang-rang a marang-rang a IP, lik'hamera tsa IP li hokahane le marang-rang a sebaka seo ka likhoele tse sothehileng tse sa sireletsehang (ke hore, Sehlopha sa 5, Sehlopha sa 5, le li-jumper tse ling tsa marang-rang) le li-switches.Ho fapana le lik'hamera tsa analog tse boletsoeng ka holimo, lik'hamera tsa IP haholo-holo li romela le ho amohela li-datagrams tsa IP ka marang-rang ntle le ho li romella lisebelisoa tsa polokelo.Ka nako e ts'oanang, video e nkiloeng ke lik'hamera tsa IP e ngotsoe ho PC leha e le efe kapa seva ho marang-rang.Ntho e kholo ka ho fetisisa ea marang-rang a marang-rang a marang-rang a marang-rang a IP ke hore khamera e 'ngoe le e' ngoe ea IP e na le aterese ea eona e ikemetseng ea IP, 'me e ka iphumana kapele. e ipapisitse le aterese ea IP marangrang ohle a video.Ka nako e ts'oanang, kaha liaterese tsa IP tsa lik'hamera tsa IP li fumaneha habonolo, li ka fumanoa ho tsoa lefats'eng lohle.

Bohlokoa ba optical fiber transceiver ho CCTV / IP network surveillance system

Litsamaiso tse peli tse boletsoeng ka holimo tsa ho shebella livideo li ka sebelisoa libakeng tsa marang-rang tsa khoebo kapa tsa bolulo.Har'a bona, lik'hamera tse tsitsitseng tsa analog tse sebelisoang ho CCTV hangata li sebelisa lithapo tsa coaxial kapa lithapo tse sothehileng tse sa sireletsehang (ka holimo ho lihlopha tse tharo tsa marang-rang) bakeng sa ho hokahanya, 'me lik'hamera tsa IP hangata li sebelisa lithapo tse sothehileng tse sa sireletsehang (ka holimo ho lihlopha tse hlano tsa marang-rang) bakeng sa ho hokahanya.Hobane merero ena e 'meli e sebelisa koporo ea koporo, e ka tlaase ho fiber cabling ho latela sebaka sa phetisetso le marang-rang a marang-rang.Leha ho le joalo, ha ho bonolo ho nka sebaka sa koporo ea hajoale ka optical fiber cabling, 'me ho na le mathata a latelang:

*Ka kakaretso lithapo tsa koporo li kengoa leboteng.Haeba ho sebelisoa likhoele tsa optical, lithapo tsa optical li lokela ho kenngoa ka tlas'a lefatše.Leha ho le joalo, sena ha se khonehe ho basebelisi ba kakaretso.Litsebi li hlokoa hore li phethe ho beha, 'me litšenyehelo tsa wiring ha li tlaase;
* Ntle le moo, lisebelisoa tsa khamera tsa setso ha li na likou tsa fiber.

Ka lebaka la sena, mokhoa oa optical fiber wiring o sebelisang li-transceivers tsa fiber optic le lik'hamera tsa analog / lik'hamera tsa IP li khahlile tlhokomelo ea batsamaisi ba marang-rang.Har'a bona, transceiver ea optical fiber e fetola lets'oao la pele la motlakase hore e be lets'oao la optical ho hlokomela khokahano ea mohala oa koporo le fiber ea optical.E na le melemo e latelang:

* Ha ho na tlhokahalo ea ho tsamaisa kapa ho fetola mohala oa mohala oa koporo o fetileng, feela hlokomela phetoho ea photoelectric ka li-interfaces tse fapaneng ho transceiver fiber optical, le ho hokahanya mohala oa koporo le fiber optical, e ka bolokang nako le matla ka katleho;
* E fana ka borokho pakeng tsa koporo medium le optical fiber medium, ho bolelang hore thepa e ka sebelisoa e le borokho pakeng tsa mohala oa koporo le lisebelisoa tsa fiber optical.

Ka kakaretso, li-transceivers tsa fiber optic li fana ka mokhoa o theko e boima oa ho atolosa sebaka sa phetisetso ea marang-rang a teng, bophelo ba tšebeletso ea lisebelisoa tse se nang fiber, le sebaka sa phetisetso pakeng tsa lisebelisoa tse peli tsa marang-rang.
