COFDM Encoder module Advantage:
- Ултра-ниско кашњење Х.265/Х.264 аудио и видео кодирање максимална подршка 1080П@60 видео снимање и кодирање у реалном времену
- ХДМИ или АВ аудио и видео улаз, након кодирања, излаз Етхернет порта или излаз на бежични модул, Брзина бита кодирања видеа може се динамички конфигурисати
- Суппорт аудио улаз и аудио излаз декодирања
- Подржава два видео записа (ХДМИ + АВ) кодирање истовременог уноса (опција, подразумевано је ХДМИ или АВ кодирање, изаберите један од два извора улаза). )
- Веб УИ или serial port UART AT command for configuration management

ФАКс
- Question1: Could you please tell me part number of this component, we try to find localy and check. Одговор 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. питање, If our camera quality is good enough for both 4 МХз и 8 МХз проток. У овом случају, Should the customer choose 4 МХз ор 8 МХз?
Одговор: 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. питање: Which is better for this tx+rx set from a receive sensitivity view?
Одговор: 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, 4МХз>6МХз>8МХз

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)
