Iphrothokholi yokuxhumana kwenethiwekhi i-onvif, iphrothokholi yangasese ye-HTTP, iphrothokholi yesixhumi esibonakalayo se-CGI
Iphrothokholi ye-Pelco kanye nephrothokholi ye-Visca yomibili iphrothokholi yokulawula imbobo ye-serial. Iphrothokholi ye-Pelco isebenzisa isikhombimsebenzisi esingu-485 ukulawula izisetshenziswa zangaphandle ezifana ne-PTZ; Iphrothokholi ye-Visca isebenzisa isixhumi esibonakalayo se-TTL ukulawula ukunyakaza ngaphakathi.
Imbobo ye-Ethernet, RS485, RS232, CVBS, okokufaka kwe-alamu nokuphumayo, okokufaka komsindo nokuphumayo, ukunikezwa kwamandla
36-phina ikhebula le-FPC lamakhamera enethiwekhi;30-phini ikhebula le-LVDS lamakhamera edijithali;Ukuze uthole ezinye izindawo zokusebenzelana, bheka umbhalo wencazelo yesixhumi esibonakalayo.
①Imojuli yekhamera yedijithali isekela kokubili okuphumayo kwenethiwekhi nedijithali;②Imojula yekhamera yedijithali ayisekeli umsebenzi we-alamu;③Izinhlamvu ezibekwe ngaphezulu kuvidiyo yemojula yekhamera yenethiwekhi zigcinwa ngemva kokuqalisa kabusha, kodwa izinhlamvu ezibekwe ngaphezulu kuvidiyo yekhamera yedijithali imojula ayilondolozwa ngemuva kokuqala kabusha;
Chofoza Ukhohlwe Iphasiwedi kusixhumi esibonakalayo sokungena, khetha indlela yokuqinisekisa ifayela, thekelisa ifayela, khiqiza ifayela elingukhiye futhi ulingenise, bese usetha kabusha iphasiwedi.
① Qiniseka ukuthi ibanga lento likhulu kunebanga eliyisisekelo lokugxila.② Ingabe isilawuli sokugxilisa ingqondo singafinyelela iphuzu elicace kakhulu? Uma isafiphele, kungahlulelwa ukuthi ithintwa ingilazi yekhava; uma kungase kucace, kwahlulelwa ukuthi kunenkinga ngejika lokulinganisa noma izingxenye zangaphakathi zelensi zisusiwe, futhi idinga ukubuyiselwa efektri ukuze ihlolwe;
Faka isixhumi esibonakalayo sezilungiselelo ze-Edge - Isiphequluli esizenzakalelayo - Ukuhambisana kwe-IE:① Setha okuthi "Njalo" ukuze uvule amawebhusayithi ku-Edge nge-IE② Setha "Vumela ukulayishwa kabusha kwamawebhusayithi ngemodi ye-IE" ukuze "Vumela"
① Ukuthi ingabe ingxenye yenethiwekhi ne-DNS yekhompuyutha nedivayisi kuyahambisana yini; ②Ukuthi kunenkinga ngekhebuli yenethiwekhi; ③Ukungajwayelekile kwekhadi lenethiwekhi yekhompyutha; ④Imikhawulo yesofthiwe ye-firewall/anti-virus
Ukubambezeleka okujwayelekile kwenethiwekhi yokunyakaza kungu-200-300ms, futhi ukubambezeleka okufushane kusethwe ekucushweni kwendawo;
Ukuthi isibonisi sembondela yezinhlamvu ze-OSD sijwayelekile, isibonisi se-OSD sijwayelekile, inkinga yokuvula ilensi, setha mathupha umphumela wokuvula; I-OSD ayikwazi ukuboniswa, bese yenza izinyathelo ezilandelayo ukuxazulula inkinga;① Ukuthi ukulanda/ukushaya ucingo kujwayelekile, ungasebenzisa i-IE9 noma isiphequluli esingaphezulu ukuze ungene kumnyakazo ukuze uhlole; uma isilawuli singafakiwe, sifake kabusha ukuze ubone ukuthi sizoba sejwayelekile yini; uma isangajwayelekile, qhubekela esinyathelweni sesibili sokuxazulula inkinga.② Sebenzisa iklayenti (4200/ODM/VLC) ukuze uhlole ukuthi isithombe sokubuka kuqala sijwayelekile yini; uma kujwayelekile, kuyinkinga yokumisa isiphequluli/ikhompyutha. Zama ukushintsha ikhompuyutha bese uhlola; uma kungejwayelekile, qhubekela esinyathelweni sesithathu ukuze uxazulule inkinga.③ Hlola ukuthi ikhebula lokuxhuma phakathi kwebhodi lenzwa nebhodi elikhulu elingaphakathi kokunyakaza lifakwe endaweni. Kuyadingeka ukuqaqa umshini bese uxhuma kabusha ikhebula; uma ikhebula lifakwe endaweni futhi kusenenkinga, lidinga ukubuyiselwa efektri ukuze lihlolwe futhi lilungiswe.
Ukulandelana komugqa kwesixhumi esibonakalayo se-LVDS sokunyakaza kwedijithali kwe-Univision kufana ncamashi nokuka-Sony. Iphinikhodi engu-1 yemojuli yekhamera yethu ingakwesokudla, futhi iphinikhodi engu-1 yakwa-Sony ingakwesobunxele.
① Hlola ukuthi ingabe iphrothokholi yembobo ikhethwe kahle yini, i-Hikvision protocol port 8000, i-onvif protocol port 80② Hlola ukuthi ingabe iphasiwedi ilungile yini③ Hlola ukuthi ifomethi yombhalo wekhodi ifana ne-NVR④ Ingabe i-multi-screen ifremu encane ayibonisi isithombe noma eyodwa ifremu egcwele yesikrini ayibonisi isithombe, hlola ukuthi ingabe ukulungiswa kufana ne-NVR
