COFDM Encoder module Advantage:
- Ультра аз кечигүү H.265/H.264 аудио жана видео коддоо максималдуу колдоо 1080P@60 реалдуу убакытта видео тартуу жана коддоо
- HDMI же AV аудио жана видео киргизүү, коддоодон кийин, Ethernet портунун чыгышы же зымсыз модулга чыгуу, видео коддоо бит ылдамдыгы динамикалык конфигурацияланышы мүмкүн
- аудио киргизүү жана аудио чечмелөө чыгарылышты колдоо
- Эки видеону колдоо (HDMI + AV) бир убакта киргизүү коддоо (тандоо, демейки HDMI же AV коддоо болуп саналат, эки киргизүү булагынан бирин тандаңыз). )
- Web UI же сериялык порт UART AT буйругу конфигурацияны башкаруу үчүн

Көп берилүүчү суроолор
- Question1: Could you please tell me part number of this component, we try to find localy and check. жооп 1: It is a inductance named LOH32PN2R2NNC.
- Suggest Check Points: If the power supply current of the board is well but there is no RF output, maybe the below component TC1-1-13MX+ is generally damaged.
- In order to avoid damage to this device during transportation (the device itself is relatively high), we ordered red glue protection for this device when we shipped it.
- The engineer also suggests that you check to see if the cable is loose or in poor contact.
- Please try to replace the FPC cable connecting the two boards
- We can provide spare parts if you're sure which one.

3. суроо, If our camera quality is good enough for both 4 MHz and 8 MHz жөндөмдүүлүгү. Бул учурда, Should the customer choose 4 MHz же 8 MHz?
жооп: Our one-way COFDM shipments use 4Mz wireless bandwidth by default, corresponding to a video bit rate of 3.12Mbps, which is enough for 1080p; If changed to 8MHz wireless bandwidth under the same conditions, the video bit rate doubles to 6.24Mbps. All customers can choose between wireless bandwidth 4MHz and 8MHz, even 6MHz can also be considered.
4. суроо: Which is better for this tx+rx set from a receive sensitivity view?
жооп: For wireless links, it can be simply considered that the receiving sensitivity will be higher at lower wireless bandwidths. From the perspective of receiving sensitivity, 4MHz>6MHz>8MHz

Vcan1870 учкучсуз UAV зымсыз видео өткөргүч жана кабыл алгыч үчүн COFDM релелик кайталоочу модулу
Single channel receiving sensitivity:
-97+/-1дБм at QPSK 8MHz,
-98+/-1дБм at QPSK 6MHZ,
Sensitivity increased by 3dbm when receiving with dual antennas
The receiver default firmware supports RTSP player, some clients prefer UDP player, which we also can offer, then RTSP player doesn't support. (RTSP and UDP can only choose one of the two firmware)
