COFDM Wireless Video HDMI Transmitter TX nifşek HDMI 1080p HD CVBS H264 Encoder COFDM-907T
COFDM-907T veguheztinek amûrek veguheztina daneya bilez e ku ji bo sepanên veguheztina vîdyoyê û bihîstweriya hêja ye. Ji bilî hewcedariyên vîdyoyê û bihîstweriya hêja ya kamerayê, stream Kodkirina, and channel rate requirements are very high. Ev dikarin H.264 codec-high quality ragihîne, a receiver image resolution up to 1920X1080P/60.

FAQs
Hema hema 14 Watts xerc.
1W ji bo mesafeya 1 km bes e. Lê em ê 2W ji we re çêbikin ku performansa wergirtina çêtirîn peyda bikin.
Ew jî bi hawîrdora weya herêmî ve girêdayî ye, gelo ew LOS an NLOS e, ji kerema xwe vîdyoya testa me kontrol bikin, gelek qat û avahî hene.
Ji bo guhertina amplifikerên hêzê yên cihêreng li ser 500 MW, 1 watt, 2 watt, an 10 dipîve. Ew ne tenê verastkirina mîhengê di nermalavê de ye, Di heman demê de hûn hewce ne ku di hundurê veguhezerê de hardware amplifikatorê Hêzê biguhezînin. Ew nikare di bikarhênerê dawîn a normal de bixebite û biguhezîne, û mesref û mezinahiya qutiya metal a veguhêz cuda ne.
Mîhenga frekansa xwerû ye 503 Mhz, 509 Mhz, 521 Mhz, û 521 Mhz hilbijêre, yek bişkojka li ser kabîneyê dikare biguhere. Heke hûn bi rastî hewceyê bandek 1.3Ghz tenê hewce ne, divê hûn modelek din hilbijêrin (1.2G an 1.4G). Ji kerema xwe hûrguliyên daxwaza xwe ji me re bibêjin.
