Sekuyisikhathi eside kudlule izikhathi ezinzima lapho kungenzeka khona ngaphandle kokwesaba okwedlulele ukucela ukunakekela ingane noma ukuphuza izimbali ngesikhathi seholide cishe cishe noma yimuphi umakhelwane esevele eseqedile. Namuhla, inkinga yokuqinisekisa ukuthi ukuphepha kwezindlu kulukhuni ngisho nasezindaweni ezincane, kungakhulumi izindawo ezinkulu zamadolobha amakhulu. Ukuvikela indlu noma ifulethi kusuka kwabangaphakathi, ukulawula umsebenzi womfana noma umninindlu, futhi ukuze uthole ukuthi ubani ovakashele ukungena emnyango - yonke le misebenzi ixazululwa kalula ngosizo lwezinhlelo zesimanje zokuqapha ividiyo, inhliziyo yekhamera efanele.
Izinhlobo zekhamera zevidiyo zokuhlola ividiyo
Uma ukhetha le ndlela yokubhekwa kwevidiyo, okokuqala, kuyadingeka ukuthi uchaze ngokucacile ukuthi yimuphi umsebenzi esifuna ukukunika wona:
- ukulungisa isimo endlini lapho kungekho khona abanikazi;
- ukuqaphela izitebhisi;
- Ukuqaphela insimu eduze kwendlu yangasese;
- ukulungiswa kwezinto ezihambayo eziwela ngaphakathi kwekhamera yekhamera.
Uma sikhuluma ngokulawula phezu kwendawo encane encane, kunengqondo ukufaka uhlelo lwe-analog video surveillance system, isithombe esithunyelwa ngesimo se-pulses. Ama-cameras for analog ukubhekwa izinhlelo zibukeka kahle elula kanye nezindleko eziphansi. Uma lo msebenzi ukulawula izinto eziningana ngesikhathi esifanayo, ngenkathi uthola isithombe sekhwalithi enhle, kuyadingeka ukufaka uhlelo lwe-digital surveillance system. Amakhamera ane-digital processing processing alahlekisela umyalo wezinga elibiza kakhulu kune-analog, kodwa anezinhlobo eziningi zokusebenza nokusebenza, okukuvumela ukuba uthole uhlelo oluphumelelayo kakhulu ekuphumeni.
Izinhlobo ezilandelayo zamakhamera zihlukaniswa nokubulawa kwazo:
- Icala . Ukufakwa kwamakhamera anjalo kwenziwa ngosizo lwabakaki, ngenkathi kungabonakala kunoma yikuphi ubuso: udonga, ugwadule ngisho nangaphansi. Inzuzo enkulu yekhamera ejwayelekile yevidiyo yikhono lokufaka cishe noma yiliphi ilensi kubo, okukuvumela ukuba uthole ukulinganisa okulungile nesithombe.
- Ukufakwa (ukulawula) . Amakhamera anjalo anesimo se-hemisphere futhi ahloswe ukufakwa endaweni engaphakathi kwendawo. Ngemodemu ye-infrared, bangakwazi ukudubula ngokumangalisayo hhayi kuphela ngosuku, kodwa futhi ebusuku. Ikhiqizwa emaphoyiseni amhlophe noma amnyama futhi ukufakwa okufanele kufinyeleleke ekungenakwenzeka.
- Okuncane . Yenzelwe ukubukwa kwevidyo efihliwe futhi ingaba nesimo kwanoma yikuphi ukuma, kusukela nxazonke kuya emgqeni.
- I-Modular. Unesimo se-lens esibekwe ebhodini. Icala lamakhamera anjalo alitholakali, ngoba laklanyelwe ukunyuka kwe-flush. Isibonelo, zingasetshenziswa esikhundleni somnyango womnyango emzimbeni womnyango wangaphambili noma ezindlini zokuvikela zokusebenzisa ngaphandle.
- Ixhunyiwe. Amakhemikhali ahlukahlukene ahlanganiswe emzimbeni womtshina womusi noma ukunyakaza.
- Ngaphandle. Ama-camcorders aklanyelwe ukuhlolwa kwevidiyo ngaphandle (ngaphandle). Zine-visor ekhethekile evikela lens kusuka ilanga glare kanye nemvula. Ukuze uvikele ngokumelene nama-vandals, amakhamera anjalo anconywa ukuthi afakwe endaweni ephakeme ayifinyeleleki ngaphandle kokusebenzisa isiteji.
- I-Antivandal. Amakhamera ane-case enamandla yensimbi nesilazi esikhethekile esincane.
- Rotary. Ama-robotic amakhamera anezilawuli ezikude namakhono okuhlela. Amakhamera anjalo angavulwa futhi avaliwe ngezikhathi ezithile, aphenduke izikhombisi-ndlela ezahlukene, unikeze ukuthunyelwa okuphezulu kwensimu.
