COFDM Wireless Video HDMI Transmitter
COFDM Wireless Video HDMI Transmitter TX Kis HDMI HD 1080P CVBS H264 Encoder COFDM-907T
COFDM-907T tus xa tawm yog cov cuab yeej siv cov ntaub ntawv xa mus rau cov vis dis aus zoo thiab daim ntawv thov xa suab. Ntxiv rau qhov ua tau zoo hauv video thiab suab uas yuav tsum tau ntawm lub koob yees duab, lub encoding kwj, and channel rate requirements are very high. Nws muaj peev xwm kis H.264 high-zoo codec, a receiver image resolution up to 1920X1080P/60.

FAQs
Yuav luag 14 Watts noj.
1W is enough for a 1km distance. But we will make 2W for you to ensure the best reception performance.
It also depends on your local environment, whether it is LOS or NLOS, please check our test video, there are many floors and buildings.
For changing different power amplifiers about 500 MW, 1 Watt, 2 Watt, los yog 10 watts. It is not just adjusting the setting in the software, You also need to change the Power amplifier hardware inside the transmitter. Nws tsis tuaj yeem ua haujlwm thiab hloov pauv ntawm cov neeg siv khoom ib txwm muaj, thiab tus nqi thiab transmitter hlau thawv loj yog txawv.
Qhov kev teeb tsa zaus yog 503 Mhz, 509 Mhz, 521 Mhz, thiab 521 Mhz xaiv, ib lub pob ntawm lub txee tuaj yeem hloov pauv. Yog tias koj xav tau 1.3Ghz band nkaus xwb, koj yuav tsum xaiv lwm tus qauv (1.2G los yog 1.4 G). Thov qhia peb cov ntsiab lus ntawm koj qhov kev thov.
