FAQs nezve Wireless Vhidhiyo Transmitter uye Receiver
Yedu isina waya vhidhiyo transmitters ane aya marudzi evhidhiyo yekupinza maficha: HDMI 1080P uye 4K HDMI, CVBS inoumbwa, SDI, AHD, IP Ethernet, BNC, kana kuti tiudze mhando yaunoda, mainjiniya wedu anozogadzirisa kuti asangane nezvinodiwa zvako.
Nzvimbo yedu yekufambisa inogona kugadziriswa nekuwedzera magetsi amplifiers. Parizvino, makuru ndiwo 15? km, 30? km, 50? km, 80? km, 100? km , uye 150km, izvo zvinoenderana nezvinodiwa nevatengi.
Eheka, nhambwe dzekufambisa dzakanyorwa pamusoro dziri mukati mese LOS mutsara wekuona. Kana paine zvipingamupinyi pakati peanotumira uye anogamuchira, NLOS (iyo isiri-mutsara-yekuona), kureba kwekutapurirana kwakaderedzwa zvakanyanya, 1km chete kana 2km, zvichienderana nenhamba yezvipingamupinyi zvepakati uye nharaunda isina waya.
Nzira imwe zvinoreva, Tinogona chete kufambisa uye kudhawunirodha vhidhiyo kana data kubva kune isina waya vhidhiyo transmitter kune inogamuchira mune imwe nzira, uye isu hatigone kurodha vhidhiyo kana data kubva kune inogamuchira kune inotapurirana. Mhando iyi inonziwo simplex.
Nzira mbiri zvinoreva kuti, kwete chete isu tinokwanisa kudhawunirodha vhidhiyo kana data kubva kune yedu isina waya transmitter kune anogamuchira, asi zvakare isu tinogona kurodha vhidhiyo kana data kubva kune inogamuchira kune inotapurirana. Izvi zvakakodzera chaizvo kushandisa drones. Iwe haugone chete kuona iyo chaiyo-nguva vhidhiyo inofambiswa kubva kune drone, asi zvakare rodha murairo kuti udzore drone kana murairo wekutonga PTZ kamera kugadzirisa kona kune transmitter.. Izvi zvinogona kushanda panguva imwe chete. Iri rudzi zvakare rakanzi hafu-dulpex kana yakazara-duplex.
