Ceeb toom
Thaum lub COFDM-905T transmitter and receiver COFDM-905T tsim ib qhov system point-to-point video wireless kis, qhov qhia tau qeeb video:
Peb indicators as video qeeb, tus nqi ntsis video, and air interface rate are mutual influence and mutual restraint. Thaum cov pa interface yog siab tshaj 5 lub sij hawm cov video chaws twg, lub qeeb video no yam tsawg kawg nkaus. Qhov no, qhov kev kuaj ntawd sij yog tias cov video ncua yog hais txog 60 milliseconds when the code is transmitted at 720P@60, thiab cov video ncua yog hais txog 130 milliseconds at 1080P@60. Lub qeeb hais txog qhov ncua ntawm cov HDMI video input kis kawg rau qhov HDMI video tso zis ntau kawg tau nyiaj, excluding tus ncua ntawm cov koob yees duab front-end txog tag kis (peb li qeeb rau ntawm ib hom SLR yees thaum txog 70 milliseconds, thiab qhov ncua ntawm ib tug naas ej hom kev ua si lub koob yees duab ntawm txog 130 milliseconds). Rau feem ntau cov ntawv scenarios, the video delay is set to about 200 milliseconds by default.
Thaum lub COFDM-905T transmitter thiab cov COFDM-905R receiver tsim ib qhov system point-to-point video wireless kis, yuav kis tau tus mob ntawd:
Wireless kis tau tus mob ntawd muaj feem xyuam rau ntau yam xws li kuaj puag ncig, cuam Ambient electromagnetic, tej yam kev mob occlusion, pa av noo, ua hauj lwm zaus, wireless bandwidth, thiab kis thiab tau txais antennas. Cov kev ntsuas tau: ib tug neeg kuaj, unmanned aircraft-mounted transmitter to fly about 100 siab meters, koj muab tau 4M QPSK wireless bandwidth, 700MHz chaw kev khiav hauj lwm zaus, 1W kis fais fab, transmitter kav hlau txais xov 3dBi ib ncig, Tau muab iav fiber ntau kav hlau txais xov koj qhov nce ntawm txog 10dBi, a distance of up to 16km (yees duab du);
peb muaj peb li kev kuaj hauv Shenzhen, community launch kawg rau qhov flyover, kav hlau txais xov hose zoo tib yam (hais txog koj qhov nce 3dBi), 340Community launch MHz, QPSK 8M Bandwidth, tus kav hlau txais xov fiberglass kawg tau nyiaj, thiab ib Yagi kav hlau txais xov, hais txog 2.2 meters loj rau ntawm tus ncej, 2.2 kilometers tseg, txhais yees duab du, a small number of high-rise buildings between the transmitter and receiver, txoj kev mus txog visually 20 dabtsi yog khoov degrees. Vim muaj cai txwv tsis pub, tsis muaj kev xeem ntxiv tau ua.

FAQs
- COFDM Video Transmitter COFDM-905T supports 1000 MHz to 2500 Mhz.
- But the COFDM Video Receiver COFDM-905R frequency range is 170-860Mhz, it does not support it, you should use the frequency down converter.
If no Power amplifier inside, tsuas - 5db
Yog, kev them nyiaj.
The SDI and AHD input cable is not including.
To be equipped with a fan, a short time no fan for testing is allowed
