COFDM Wireless Video uqhagamshelwano lwetshiphu emsebenzi Gazi
COFDM Wireless Video lwetshiphu Gazi TX Transmission lwetshiphu HD 1080P CVBS H264 Encoder COFDM-907T
Umthumeli weCOFDM-907T sisixhobo esikhawulezayo sokuhambisa idatha kwizicelo ezikumgangatho ophezulu wevidiyo kunye nokusasaza. Ukongeza ividiyo ekumgangatho ophezulu kunye neemfuno zekhamera, zokuvela enkhowudingi, and channel rate requirements are very high. It angadlulisela codec H.264 ezikumgangatho ophezulu, a receiver image resolution up to 1920X1080P/60.

Ii-FAQs
phantse 14 IiWatts ukusetyenziswa.
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, okanye 10 watt. Ayikokulungisa nje useto kwisoftware, Kufuneka kwakhona utshintshe i-Hardware ye-amplifier yamandla ngaphakathi kwi-transmitter. Ayinakusebenza kwaye itshintshe kwisiqhelo somsebenzisi, kunye nexabiso kunye ne-transmitter ye-metal box size yahlukile.
Isetingi yefrikhwensi emiselweyo yile 503 MHz, 509 MHz, 521 MHz, kwaye 521 Mhz ukukhetha, iqhosha elinye kwikhabhinethi lingatshintsha. Ukuba ufuna ngokwenene ibhendi ye-1.3Ghz kuphela, kufuneka ukhethe enye imodeli (1.2G okanye 1.4G). Nceda usixelele iinkcukacha zemfuno yakho.
