- HDMI po'o le AV leo ma fa'aoga vitio, pe a uma le fa'ailoga, le Ethernet port output po'o le Output i le module uaealesi, e mafai ona dynamically configured fua faatatau vitio encoding bit
- Lagolago sao o leo ma galuega faatino decoding otio
- Lagolago ni vitio se lua (HDMI + AV) fa'ailoga fa'akomepiuta fa'atasi (filifiliga, o le faaletonu ole HDMI po'o le AV encoding, filifili se tasi mai le lua mea e maua mai ai). )

FAQs
1. What should I do when I found one Tx module doesn't generate RF output power?
- Fesili 1: E mafai ona e ta'u mai ia te au se vaega numera o lenei vaega, matou te taumafai e suʻe le lotoifale ma siaki. tali 1: O se inductance igoa LOH32PN2R2NNC.
- Fautua Faailoga Siaki: Afai o loʻo lelei le eletise o loʻo i ai nei o le laupapa ae leai se RF gaioiga, atonu o le vaega i lalo TC1-1-13MX+ e masani ona faaleagaina.
- Ina ia aloese mai le faaleagaina o lenei masini i le taimi o felauaiga (o le masini lava ia e fai si maualuga), sa matou okaina le puipuiga o le kelu mumu mo lenei masini pe a matou lafoina.
- Ua fautua mai foi le inisinia e te siaki pe ua matala le uaea pe leaga le fesootaiga.
- Fa'amolemole taumafai e sui le uaea FPC e feso'ota'i ai laupapa e lua
- We can provide spare parts if you're sure which one.
2. E mafai ona e ofoina mai ia te aʻu le faila o le UART AT mo lenei faʻataʻitaʻiga?

3. E fa'afefea ona lagolagoina e lenei COFDM Vitio transmitter ma le fa'ameamea se meapueata IP?
1. E le faigofie ona faʻafesoʻotaʻi i le IPC mo se so'otaga COFDM e tasi. E iai le matou faʻataʻitaʻiga H264, lea e fesoʻotaʻi atu i le IPC faʻaoga e ala i le faʻalauteleina o le taulaga fesoʻotaʻiga, ae o loʻo iai manaʻoga mo faʻataʻitaʻiga IPC (e le o faʻataʻitaʻiga uma o le IPC e mafai ona fesoʻotaʻi lelei ma fesoʻotaʻiga COFDM), ua matou tofotofoina le IPCs o Hikvision, Dahua, ma Xiongmai, ma maua ai o le aafiaga sootaga o Hikvision e fai si lelei.
2. E le mafai ona aveese sa'o le HDMI CVBS encoder ma faʻafesoʻotaʻi le IP Camera i le COFDM Transmitter board. E tasi le auala COFDM fesoʻotaʻiga i le IPC e manaʻomia auala faʻapitoa faʻapitoa e iloa ai.
3. O le auala sili o le fautuaina lea o le faʻaaogaina o la matou transceiver felauaiga ata e lua, lea e lagolagoina sa'o le IP mea pu'eata.
4. Afai e tatau i le tagata faʻatau ona faʻaoga le COFDM transmitter board e lagolago ai le IP camera, e lua itu e ao ona silasila i ai.
5. O le manatu muamua o se faʻafitauli faʻapitoa. Matou te manaʻomia le faʻaogaina o se isi auala e faʻatagaina ai fesoʻotaʻiga COFDM e tasi e faʻaoga ma le IPC.
6.Afai e te mafaufau i le IPC mai le vaaiga o le faʻaititia o tau, you don't need to consider it. Ona o le laupapa encoding ma decoding laupapa e manaʻomia pea, e le mafai ona sefe le tau.
7. The second point is the customer's usage habit, lea ua le toe avea ma auala masani sooga e lua. E mafai ona latou matamata i le IP Camera Video ma e oʻo lava i le pulea o le PTZ o le IP Camera e ala i le itulau web poʻo le PC-itu PC software (UART AT poloaiga).
8. Ona o lenei faʻataʻitaʻiga fesoʻotaʻiga uaea ole COFDM soʻotaga tasi-ala; e leai se fa'amatalaga fa'aliliu (na'o le tasi le auala felauaiga; e le mafai ona tu'uina atu fa'amatalaga mai le tagata e taliaina i le transmitter); the customer can only watch the video of the IP Camera and cannot reversely configure the IP Camera's parameters or control the PTZ of the IPCamera.
9. O se fa'afitauli lea e le'i amana'ia e le to'atele o tagata fa'atau i le taimi muamua ma fa'asea mulimuli ane ina ua uma ona fa'aaogaina.
10. So we don't recommend that the client choose a one-way COFDM transmitter and receiver for the IP camera. E i ai se matou fofo sili atu mo le IP Camera e ala i lua feso'ota'iga feso'ota'iga vitiō.
4. Fa'amolemole tu'u mai ia te a'u le C/N Manaomia (BER=2x10-4 ina ua uma Viterbi) mo eseese le bandwidths 2, 4, 6, ma 8 Mhz o fesoʻotaʻiga vitio HDMI matou te faʻaogaina?

1. I le taimi nei, e na'o le lua e tu'uina atu e le tagata e fa'ailoa le malosi o fa'ailo ma le fua fa'aletonu, ma e leai se C/N parameter
2. O a mea e te manaʻomia e faʻafetaui e tusa ai ma bandwidths eseese? Afai o se vitio code stream, o le transmitter encoding laupapa lava ia o le a otometi lava ona fuafua le fua faatatau code stream vitio talafeagai e tusa ai ma le faaaogaina i le taimi nei uaea laina (bandwidth, GI, CR, ma isi tulaga faapena), ma o le a maua le fua o le code video pe a uma ona suia le bandwidth ma le laupapa parameter o le a otometi lava ona fetuunai.
3. fesili, Afai e lelei a tatou meapueata mo mea uma e lua 4 MHz ma 8 MHz bandwidth. I lenei tulaga, Pe tatau ona filifili le tagata faatau 4 MHz po o 8 MHz?
tali: O a matou uta COFDM e tasi le auala e faʻaaogaina le bandwidth wireless 4Mz e ala i le faaletonu, e fetaui ma se ata vitio o le 3.12Mbps, lea e lava mo 1080p; Afai e suia i le 8MHz wireless bandwidth i lalo o tulaga tutusa, e faaluaina le fua o le vitio i le 6.24Mbps. E mafai e tagata fa'atau uma ona filifili i le va o le bandwidth wireless 4MHz ma le 8MHz, e oo lava i le 6MHz e mafai foi ona mafaufauina.
4. fesili: O le fea e sili atu mo lenei seti tx + rx mai se vaaiga maaleale maua?
tali: Mo so'oga uaealesi, e mafai ona na'o le manatu o le a sili atu le lagona o le mauaina i lalo o bandwidths uaealesi. Mai le vaaiga o le mauaina o lagona, 4MHz>6MHz>8MHz
6. E i ai sau COFDM Relay Repeater Modules mo le Fa'aliliuina Vitio Uaealesi ma le Receiver？

7. E mafai ona auina mai ia te a'u se fua fa'amatalaga o le maaleale mo 4/6/8 MHz mataupu? Faataitaiga, mo QPSK, 1/2CR, 1/32GI what threshold reception RX's input level (dBm)?
Auala e tasi e maua ai lagona maaleale:
-97+/-1dbm ile QPSK 8MHz,
-98+/-1dbm ile QPSK 6MHZ,
Ma'ale'ale fa'asili i le 3dbm pe a maua fa'atasi ma antenna lua
9. O fea e mafai ona ou siiina ai le UDP player? Matou te fautuaina le Splayer_v4.2_2020.6.6 lea matou te fa'aoga soo.
E lagolagoina e le tagata fa'amaumau fa'aletonu le RTSP, o nisi tagata fa'atau e fiafia i le ta'aloga UDP, e mafai foi ona matou ofoina atu, then RTSP player doesn't support. (RTSP ma le UDP e mafai ona filifili se tasi o le firmware e lua)
