CCTV: izinhlobo. Indlela uxhuma ikhamera analog? Isikimu analog ikhamera. Ekhethwayo ikhamera analog

amakhamera Analog asetshenziswa amabhizinisi ngoba video ukubhekwa lezinto. onobuhle yamanje zenziwa abanamalensi ebucayi. amakhamera amaningi akhiwe conductivity eliphezulu. Ngokusho kwe-idivayisi awafani. Futhi, nemingcele eziyisisekelo idingekile ukuze kokuma kwekhamera futhi ubude ebalulekile. Ngaphezu kwalokho, cabanga imvamisa zedivayisi. , Kunconywa ukuba sicabangele ukuguqulwa isikimu ejwayelekile baluhlolisise ku amakhamera analog hlobo.

uhlelo chamber

Standard isikimu analog ikhamera kuhilela ukusetshenziswa contact lens, futhi control unit mojuli. Lenses zisetshenziswa ukuzwela high and low. Isiqophi okukhiphayo asethwe uchungechunge ezahlukene. Thyristors Site onobuhle imvamisa 400 MHz. Ngaphezu kwalokho, kubalulekile ukuqaphela ukuthi adapters babe amakhamera efakwe nabalawuli.

izinhlobo onobuhle

Kunezinhlobo ezahlukene amakhamera analog. Ngu uhlobo ukufakwa onobuhle zihlukaniswe ukuguqulwa ngaphakathi kanye nabangaphandle. inketho Okokuqala kangcono nehhovisi izindawo. Babesebenzisa encane conductance-matrix. Uma lokhu engela lingaphansi kuka-degree angu-12. Uma sicabanga ikhamera yangaphandle, bona baye basungula lens ebanzi. kumadivayisi abaningi basebenzisa iyunithi yezintambo. Umkhawulo engela onobuhle kulingana degrees 160. Ngokusho ukwakhiwa wayehlala kude futhi rotary kwelivi-ukuguqulwa.

amashubhu kwangaphakathi

Yangaphakathi CCTV ekhiqizwa nge Racks ukufakwa. onobuhle yamanje zinezikhathi lesinqumo high, ayesebenzisa wire modulator. Ubude ebalulekile amadivaysi iqala ngo 3.5 amamitha.

Indlela uxhuma analog ikhamera uhlobo zasekhaya? Abanye onobuhle amiswa ngokuqondile ngokusebenzisa umqhubi komugqa. Extenders for ukuguqulwa akhethiwe isiqondiso esihle.

ukuzwela inketho emakamelweni bangaphakathi cishe 5.5 mV. Iningi amadivayisi kwenziwa okukhipha ividiyo PP. Kufanele kuphawulwe ukuthi zikhona izinguquko ukuze modulators zesikhashana. Imvamisa yokusebenza ngesikhathi emakamelweni angaphakathi imayelana 450 MHz. onobuhle amaningi akhiwe nge ohlelweni ukuphepha. Kufanele kuqashelwe ukuthi le amadivaysi zingafani ngokoMthetho umsindo. Kwezinye izimo, emakamelweni uxhumano ezivezwa adapters siteshi.

ikhamera yangaphandle

ikhamera yangaphandle ume wokubuka engeli ebanzi. Babesebenzisa ukuvikeleka okungcono. ukulungiswa ezinjalo zivame ukufakwa emnyango izakhiwo ehhovisi. amamodeli futhi ivame ukusetshenziswa phambi kwezitolo ezidayisa. Engela umbono zingabantu ngokuvamile ingeqi 230 degrees. Abanye onobuhle zenziwa nge-adaptha oxhumana naye okukhipha ividiyo. Ukulungiswa ipharamitha kumaseli kuyahluka. onobuhle Iningi lusekelwa ngamandla modulator. Ngaphezu kwalokho, kubalulekile ukwazi ukuthi zikhona amakhamera nge multi-channel adapters. Sepharamitha ukusebenza imvamisa ifinyelela esiphezulu amadivayisi 450 MHz. Lenses esetshenziswa amakilasi ezahlukene. Imbobo ngesikhathi esifanayo isethi P40 chungechunge.

Uma ukhetha ukulungiswa kubalulekile sinake izindlela kudivayisi. Ukuze ebusuku sokudutshulwa edingekayo isihlungi ekhethekile. Kufanele kuphawulwe ukuthi zikhona onobuhle ngozwelo eliphezulu. Ixhuma amakhamera engenantambo kwenziwe ngokusebenzisa adaptha umugqa. Comparators amadivayisi akhethiwe ongaphakeme inethiwekhi ohlangothini. Uma sicabangela imodeli elula nge counter Ngamafuphi, omiswe module olulodwa. onobuhle yamanje zenziwa nge ukukhululwa kwe-AU. Ukuze uwanike amandla ukusebenzisa thyristors. Lezi zinto zidayiswa khona noma angabi khona rectifier. Kubalulekile ukuphawula ukuthi zikhona izinguquko ukuze abalawuli olunezintambo, avalwa phezu kwe-module. Ukuze uxhume ukuguqulwa enjalo usungula contactor ekhethekile. Ikhamera sidla ngokuzenzakalela kukhompyutha. Ukuze usethe i-imishini, iya kwimenyu zedivayisi. Kulokhu, ukuthi okuningi kuncike endleleni yesistimu yokusebenza.

PTZ amakhamera

Rotary CCTV zihlanganisa matrix multi-umzila kanye ne-lens evamile. I module isetshenziswa ne thyristor. Ixhuma i ikhamera analog kwenzeka kaningi kakhulu ngokusebenzisa inkinobho. Uma sicabanga imodeli ejwayelekile, it has inkomba Imvume 780 by Amaphikseli 500. Amanye amadivayisi akhiqizwa ngokusekelwa ifomethi CP.

Kufanele kuqashelwe ukuthi le onobuhle babe Racks mobile ekhethekile. Actuators asetshenziswa kuphela uhlobo isilawuli. Ezinye amakhamera abelwe ukumelana ongaphakeme. Rectifiers ngabo zikhethwa phezu okukhiphayo ezimbili. Ukuze ufake edingekayo ukuguqulwa olwandisa pin esivala okuphakela amandla. Ukulungisa ikhamera usebenzisa ikhompyutha siqu ezivamile.

amaseli Wiring izakhi

Yakhiwe amakhamera analog kungenzeka ixhunywe nge dipole modulator. Isilawuli isetshenziswa yesixhumo olulodwa. Ochwepheshe bathi lemifanekiso esetshenziswa contactor.

Uma sicabangela ukuguqulwa yezintambo, banezizathu PP okukhiphayo. Kulokhu adaptha lisetshenzisiwe olwandisa. Kubalulekile futhi ukuba uqaphele ukuthi amanye model kuphela axhunyiwe ngokusebenzisa contactor ukuba okukhiphayo ezintathu. Kulokhu, ukucushwa imishini kungenxa kukhompyutha siqu. Imodeli standard kuyinto adjustable ngokusebenzisa panel. Uma ucabangela ukuguqulwa modulator, kuyafaneleka ukuthi udinga ukufaka AC isilawuli. I-adaptha le njongo isetshenziselwa iziteshi ezintathu. Ukuze niqede ukujikeleza ngeke zihambelane reamer ongaphakeme-ukudaza inkani.

Uhlobo oluhle ikhamera analog

ActiveCam AC-TA461IR2 - nansi best ikhamera analog, muva nje eye bayindlala kakhulu. It has a lens eliphezulu elikuvumela ukudubula ephezulu definition vidiyo. I-matrix imodeli akusho athatha ugesi. Ngaphezu izinzuzo idivayisi akufanele zihlanganisa ukuguqulwa conductivity ezimbi. Izazi zikholelwa ukuthi ukusebenzisa idivayisi Kulula kakhulu ukufaka. Kufanele kuphawulwe ukuthi imodeli unomzimba omkhulu. Lemifanekiso kuleli cala uhlobo photosensitive.

Ukufaka kwikhompyutha

amakhamera Analog exhunywe ngekhompyutha nge-adaptha. Kulokhu, ukuthi okuningi kuncike endleleni iphaneli okukhiphayo. Uma sicabanga idivayisi RK isixhumi basebenzisa contactor ngaphandle extender. Kulokhu ekamelweni ixhunyiwe ngqo nge contactor. Kufanele kuphawulwe ukuthi ukuguqulwa kungenziwa amisiwe usebenzisa umshayeli. Amanye amadivayisi benziwe isivuno PE. Abanaso silingane extender ejwayelekile. Adaptha ifanelekile ukuze ukhethe transceiver. ochwepheshe abaningi basebenzisa kuphela version yezintambo. Uma ufake amakhamera amaningi, sewugubha asetshenziselwe le nhloso. amadivaysi Modern akhiqizwa ngesikhathi okukhiphayo ezimbili.

Uxhumano nge-laptop

Through the laptop kungenziwa exhunywe amakhamera analog ezinhlobo ezehlukene. Uma sicabangela kudivayisi lelivakalako, okuyinto osetshenziselwa transceiver. Rectifiers ezifakiwe ngezihlungi ngaphandle kwalo. Kufanele kuqashelwe ukuthi le amakhamera zixhunywe ngokusebenzisa amamojuli. Ukukhuluma kwesiteshi ukuguqulwa, kuyafaneleka ukuthi wasebenzisa KE izixhumi. Konke lokhu kusikisela ukuthi module ejwayelekile asifanele uxhumano.

Kulokhu, ukuguqulwa ingasetshenziswa kuphela nge-adaptha dipole. Kulesi iqoqo wave rectifier inkinobho. Ukuze ulungise ikhamera kuzodingeka ukuya control panel. Okulandelayo, kubalulekile ukuthola idivayisi entsha, uma le njongo umsebenzi ukuskena. Ngemva yilokhu okuyomane ubuyekeze umshayeli ukuguqulwa.

Ukusetshenziswa kwe-module 10 B

Amandla amayunithi 10 ofanele kuphela amakhamera zangaphandle. Ukuze uxhume contact asetshenziswa modulators ukulungisa. Kulokhu, nabaqondisi ezifakiwe nge adapters ka conductivity ezahlukene. amadivaysi Modern benziwe isivuno RK. Sinenkosi liner ejwayelekile.

Kufanele kuphawulwe ukuthi zikhona amadivayisi nge-AC. Ikhamera onobuhle ezifana kuphela zinhlobo efanelekayo ezishintshwe izakhi. Ngokushesha Eliminator esetshenziswa ongaphakeme-Ukumelana hlobo. Ochwepheshe bathi thyristor kukhethwa adaptha intambo. I olwandisa lokuqala ixhunywe wesifunda. Ngemva kwalokho, ukufaka ikhamera bese ugesi.
