Iikhamera zeCCTV: Iintlobo. Indlela ukudibanisa ikhamera analog? Scheme analog camera. Oluthandayo lwe camera analog

iikhamera Analog asetyenziswa kumashishini yevidiyo esweni izinto. imifuziselo yangoku zenziwa kunye lenses ezibuthathaka. iikhamera ezininzi zenziwe conductivity ophezulu. Ngokutsho ukusonjululwa isixhobo zahluke kakhulu. Kwakhona, kwiipharamitha ezisisiseko eziyimfuneko ukuze athwale ikhamera engile kunye ubude. Ukongezelela, cinga rhoqo kwefowuni. , Kucetyiswa ukuba siqwalasele loyamano inkqubo eqhelekileyo ukuba baphande ngokucokisekileyo kwi iikhamera uhlobo analog.

scheme egumbini

Standard scheme analog khamera kubandakanya ukusetyenziswa lens zoqhagamshelwano, kwaye iyunithi yolawulo umnqongo. Lens isebenze uvakalelo oluphezulu nezisezantsi. iziphumo zevidiyo ibekwe series ezahlukeneyo. Thyristors ifanele imifuziselo kunye rhoqo 400 MHz. Ngaphezu koko, kubalulekile ukuqaphela ukuba ngokubakho kufuneka iikhamera ezifakwe kunye nabalawuli.

iintlobo imifanekiso

Kukho iindidi ezahlukeneyo iikhamera analog. Xa uhlobo iimodeli ufakelo azizahlulo ukuguqulwa lwangaphakathi nolwangaphandle. ukhetho lokuqala ifanele izibonelelo ofisi. Basebenzisa matrix conductance encinane. Xa le angle ngaphantsi kwe degrees 12. Ukuba sicinga ikhamera yangaphandle, they sungula lens ngokubanzi. izixhobo ezininzi usebenzisa iyunithi kwentambo. Nciphisa engile njengezibonelo ilingana degrees 160. Ngokutsho ukwakhiwa kude kunye rotary nayiphi-ukulungiswa.

zohlobo lwe yangaphakathi

iikhamera zeCCTV yangaphakathi enziwa kunye nezinye izinto ze ufakelo. imifuziselo yangoku luphawulwa nokugqama, basebenzisa ucingo modulator. Ubude yinqontsonqa yayo izixhobo iqala eemitha 3.5.

Indlela ukudibanisa i camera uhlobo basekhaya analog? Ezinye iimodeli zaziwa ngqo nge umqhubi yomgama. Extenders zokuwaguqula zikhethiwe ingculaza.

nobuzaza ukhetho emagumbini nama-5.5 MV. Uninzi izixhobo kwenziwa nevidiyo kwimveliso PP. Kufuneka kuqatshelwe ukuba kukho ulungiso ukuya modulators yenguqu. Amaza yokusebenza kwi amagumbi yangaphakathi 450 MHz. imifuziselo ezininzi ezenziwe kwinkqubo yokhuseleko. Kufuneka kuqatshelwe ukuba izixhobo kwahluka ngokwemiqathango ingxolo. Kwezinye iimeko, amagumbi uqhagamshelo eveliswe amaqhoshana channel.

ikhamera yangaphandle

camera lwangaphandle ukuma ukubukela engile ngokubanzi. Basebenzisa ukukhuselwa ngcono. Izilungiso ezinjalo badla efakwe emnyango kwezibonelelo ofisi. imizekelo nazo zisetyenziswa phambi ezivenkileni. Abone ngayo bona ngokubanzi ayidluli degrees 230. Ezinye iimodeli zenziwa kunye nomfowunelwa adaptha ukuya kwimveliso yevidiyo. Isisombululo parameter iiseli iyahluka. Imifanekiso anikwe amandla a modulator. Ngaphezu koko, kubalulekile ukuba kuqatshelwe ukuba kukho iikhamera kunye ezisebenza ngokubakho multi-channel. Ipharamitha frequency ukusebenza ufikelela ubuninzi kwizixhobo 450 MHz. Lens basebenzisa kwiiklasi ezahlukeneyo. Imbobo ngexesha elifanayo elimisiweyo P40 series.

Xa ukhetha utshintsho kubalulekile ukunikela ingqalelo iindlela idivayisi. Kuba ukudubula ebusuku efunekayo lokucoca okhethekileyo. Kufuneka kuqatshelwe ukuba kukho onobuhle uvakalelo oluphezulu. Idibanisa iikhamera wireless lihanjiswa kulo zombini umgca. Comparators izixhobo ezikhethiweyo womnatha zemiyalelo ephantsi. Xa siqwalasela umfuziselo elula ikhawuntala emfutshane, kokuba limiselwe imodyuli elinye. imifuziselo yangoku zenziwa kunye kukhululwe AU. Ukuze sikwazi ukuba isicelo thyristors. Ezi zinto zithengiselwa kunye okanye ngaphandle rectifier. Kananjalo kubalulekile ukuba siqaphele ukuba kukho ulungiso nabaqondisi igxunyekwe, avalwa kwi kwimodyuli. To connect a kwako onjalo simisela lwekontraka okhethekileyo. Le khamera kondliwa kwikhompyutha. Ukuze kumiswe izixhobo, yiya kwimenyu kwefowuni. Kulo mzekelo, oku kuxhomekeke kwinkqubo yokusebenza.

iikhamera PTZ

iikhamera zeCCTV rotary ziquka matrix multi-itshaneli kunye lens eqhelekileyo. Imodyuli isetyenziswa ne thyristor. Ukuhlobanisa i camera analog kwenzeka amaninzi ngalo iswitshi. Xa siqwalasela umzekelo umgangatho, it has Isalathisi imvume yi-780 nge pixels 500. Ezinye izixhobo ziveliswa kunye nenkxaso ifomati CP.

Kufuneka kuqatshelwe ukuba beye nezinye izinto ezikhethekileyo mobile. Actuators zisetyenziswa kuphela uhlobo umlawuli. Ezinye iikhamera zabelwa ukuxhathisa eliphantsi. Rectifiers ukuba akhethwe kwi iziphumo ezimbini. Ukuze ufake i efunekayo ukuguqulwa olwandisa iphina ukuba ivale unikezelo amandla. Ukuze ukuqwalasela ikhamera usebenzisa ikhompyutha eqhelekileyo zobuqu.

Zikagesi izakhi iiseli

Izakhi iikhamera analog ukuze izakubanodibaniso nge dipole modulator. A isilawuli isetyenziswa ne adaptha elinye. Iingcali zithi lokucoca isetyenziswa ne lwekontraka.

Ukuba sicinga ukuguqulwa Esetyenzisiweyo, sinaye PP output. Kule meko zombini lusetyenziswa olwandisa. Kubalulekile ukuqaphela ukuba ezinye iimodeli ezidibene kuphela lwekontraka ukuya iimveliso ezintathu. Kulo mzekelo, uqwalaselo izixhobo kungenxa computer siqu. Umfuziselo standard yi adjustable ngokusebenzisa panel. Xa kuqwalaselwa nenguqulo modulator, kubalulekile ukukhumbula ukuba kufuneka uzifakelele AC isilawuli. Zombini ngenxa yale njongo sisetyenziselwa iindlela ezintathu. Ukugqiba wesekethe uya lulungele reamer esezantsi-ukuxhathisa.

Uhlobo oluhle camera analog

ActiveCam AC-TA461IR2 - oku ikhamera ilungileyo analog, nto leyo kutshanje siye kwemfuno enkulu. Kuye lens ophezulu ezikumgangatho ekuvumela ukuba kutolwe Isinxulumaniso yevidiyo. I matrix yemodeli akuthethi kudle umbane omninzi. Ukongeza iingenelo isixhobo kufuneka ibandakanye embi ukuguqulwa conductivity. Iingcali zikholelwa ukuba icebo Kulula kakhulu ukuba ukufaka. Kufuneka kuqatshelwe ukuba umfuziselo unomzimba omkhulu. Isihluzo kulo mzekelo uhlobo photosensitive.

Ukufaka kwikhompyutha

iikhamera Analog eqhagamshelwe nge ikhompyutha ne-adaptha. Kulo mzekelo, oku kuxhomekeke lenjongo kwimveliso. Ukuba sicinga isixhobo RK isinxibelelanisi basebenzisa lwekontraka ngaphandle extender. Kulo mzekelo egumbini elidityaniswe ngqo nge lwekontraka. Kufuneka kuqatshelwe ukuba ukuguqulwa nokuba iqwalaselwe nge umqhubi. Ezinye izixhobo eyenziwe isivuno eBhayi. Abayi yaxaka extender eqhelekileyo. Adaptha kunilungele ukuba ukhethe transceiver. Iingcali ezininzi basebenzisa kuphela yinguqulelo kwentambo. Ukuba ufakela iikhamera ezininzi, le yomfumani zisetyenziselwa le njongo. izixhobo Modern ziveliswa kwi iziphumo ezimbini.

Connection nge laptop

Esebenzisa laptop kungaba izakudityaniswa kubekanye iikhamera analog kweentlobo ezahlukeneyo. Ukuba sicinga isixhobo projektha, nto leyo isetyenziselwa transceiver. Rectifiers zifakwa kunye lwamacebo okucoca ngaphandle kwayo. Kufuneka kuqatshelwe ukuba iikhamera ziyaxhonywa ngokusebenzisa iimodyuli. Ethetha channel yokuphila, kubalulekile ukuqaphela ukuba asebenzisa KE izihlanganisi. Konke oku kubonisa ukuba imodyuli standard akafanelanga kusetyenziselwa uqhagamshelo.

Kulo mzekelo, ukuguqulwa zingasetyenziswa kuphela adaptha dipole. Kule iseti lwamaza rectifier iswitshi. Ukulungisa icamera ukuya panel yolawulo. Okulandelayo, kubalulekile ukuba ukubona isixhobo esitsha, kunikwa le njongo umsebenzi isixhobosovavanyo lwemifanekiso. Emveni koku ndiya kuyihlaziya kuphela umqhubi ukulungiswa.

Ukusetyenziswa umnqongo 10 B

units Power 10 efanelekileyo kuphela iikhamera zangaphandle. To connect umfowunelwa modulators uguqulo kancincane ziyasetyenziswa. Kulo mzekelo, nabaqondisi zifakwa kunye ezisebenza ngokubakho of conductivity ezahlukeneyo. izixhobo Modern zenziwa ngendlela isivuno RK. Zinelungelo nqanawa eqhelekileyo.

Kufuneka kuqatshelwe ukuba kukho izixhobo kunye AC-adaptha. Ikhamera njengezibonelo ezinjalo kuphela ngeentlobo ezifanelekileyo ngobunjineli. Ngoko nangoko eliminator wasebenzisa uhlobo ephantsi-ukuxhathisa. Iingcali zithi ukuba thyristor ikhethiwe ukusuka adaptha ntambo. Le olwandisa lokuqala liqhagamshelene wesekethe. Emva koko, ukufaka ikhamera namandla ubonelelo.
