COFDM Encoder module Advantage:
- Izjemno nizka zakasnitev H.265/H.264 kodiranje zvoka in videa največja podpora 1080P@60 za zajemanje in kodiranje videa v realnem času
- HDMI ali AV avdio in video vhod, po kodiranju, izhod vrat Ethernet ali izhod v brezžični modul, Bitno hitrost kodiranja videa je mogoče dinamično konfigurirati
- Podporo avdio vhod in avdio izhod dekodiranja
- Podpira dva videa (HDMI + AV) hkratno vnosno kodiranje (možnost, privzeto je kodiranje HDMI ali AV, izberite enega izmed dveh vhodnih virov). )
- Spletni uporabniški vmesnik ali ukaz serijskih vrat UART AT za upravljanje konfiguracije

pogosta vprašanja
- Question1: Could you please tell me part number of this component, we try to find localy and check. odgovor 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. vprašanje, If our camera quality is good enough for both 4 MHz in 8 MHz pasovne širine. V tem primeru, Should the customer choose 4 MHz ali 8 MHz?
odgovor: 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. vprašanje: Which is better for this tx+rx set from a receive sensitivity view?
odgovor: 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

Single channel receiving sensitivity:
-97+/-1SMO at QPSK 8MHz,
-98+/-1SMO 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)
