Cheap Wireless video transmitter and receiver’s small screen has great help on signal strength lock
Maybe you have already watched our test video of COFDM-912T, it supports long-distance at the building, tree and in city busy traffic.
Many clients ask me why the receiver has so thick with a small screen.
In this video, it can be seen that as the transmitter goes farther and farther, the signal strength becomes lower and lower, When the SNR is lower than 6dB, the picture appears mosaic, and when the SNR is lower than 3dB, the receiver’s picture appears black. So the operator can make corresponding adjustments according to the parameters displayed by the meter at any time.
The model COFDM-912T wireless transmitter and receiver can provide a good transmission effect in 25 kilometers at the light of sight and 1.5km at non-light of sight. In the actual use process, if the signal is interrupted, or the receiver’s monitor is stuck or frozen, it is annoying to be unable to analyze the cause in time and take appropriate recorrect action. Because it is long-distance wireless transmission and reception, sometimes there is a local signal transmission tower that interferes with the transmitter or receiver in the local environment, it is impossible to determine the cause in time and accurately.
If there is a function, especially a small screen, that it can accurately display whether the current transmitter and receiver signals are locked or unlocked in real-time, and the screen can display the current signal strength in real-time, it will be helpful for wireless transmitters and receivers. Empeleni, the receiver of COFDM-912T has this function. Although adding a screen will make the overall size appear large, the addition of this screen is very helpful for real-time monitoring of signal strength. Other functions include viewing the version number of the system, upgrading, modifying the parameters of the transmitter and receiver in time, and enabling or disabling AES265 encryption.
Thanks for watching, please contact us with any further questions. I will show you the details in the next video.

Izithutha zethu zevidiyo ezingenazintambo zinalezi zinhlobo zezixhumanisi zokufakwayo kwevidiyo: I-HDMI 1080P ne-4K HDMI, Inhlanganisela ye-CVBS, SDI, I-AHD, IP Ethernet, BNC, noma usitshele ukuthi udinga luphi uhlobo, unjiniyela wethu uzolungisa ukuze ahlangabezane nesidingo sakho.
Ibanga lethu lokudlulisela lingalungiswa ngokungeza izikhulisamandla. Okwamanje, okuyizona eziyinhloko 15km, 30km, 50km, 80km, 100km , futhi 150km, okuncike ezidingweni zamakhasimende.
Kunjalo, amabanga okudlulisela abalwe ngenhla wonke angaphakathi LOS ububanzi bomugqa wokubona. Uma kukhona izithiyo phakathi komthumeli nomamukeli, NLOS (okungewona umugqa wokubona), ibanga lokudlulisela liyancipha kakhulu, 1km noma 2km kuphela, kuye ngenani lezithiyo ezimaphakathi nendawo yendawo engenazintambo.
Indlela eyodwa kusho, Singadlulisela futhi sidawunilode ividiyo noma idatha kusuka kusihambisi sevidiyo esingenantambo siye kumamukeli ngendlela eyodwa, futhi asikwazi ukulayisha ividiyo noma idatha esuka kumamukeli iye kumthumeli. Lolu hlobo lubizwa nangokuthi i-simplex.
Izindlela ezimbili kusho lokho, hhayi kuphela ukuthi singadawuniloda ividiyo noma idatha kusuka kusidlulisi esingenantambo siye kumamukeli, kodwa futhi singalayisha ividiyo noma idatha kusuka kumamukeli kuye kusidlulisi. Lokhu kulungele kakhulu ukusebenzisa ama-drones. Awukwazi ukubona kuphela ividiyo yesikhathi sangempela edluliselwa kusuka ku-drone, kodwa futhi layisha umyalo wokulawula i-drone noma umyalo wokulawula ikhamera ye-PTZ ukuze ulungise i-engeli kusidluliseli.. Lokhu kungasebenza kanyekanye. Lolu hlobo luphinde lwaqanjwa ngokuthi i-half-dulpex noma i-full-duplex.

Ama-transmitter amaningi wevidiyo angenantambo manje ayasekela I-AES128 noma i-AES256 bit encryption kanye nokuqaqwa, kuye ngokuthi iyiphi imodeli oyikhethayo. Sicela usithinte ukuze uqinisekise.
Amafrikhwensi akho kokubili isidlulisi sevidiyo esingenantambo kanye nesamukeli sevidiyo esingenantambo kungashintshwa. Abasebenzisi badinga ukuthenga amabhodi okumisa amapharamitha engeziwe.
Nokho, uma kucatshangelwa ukuthi isikhulisi samandla esihambisanayo kanye nothiyo sekuvele kulungisiwe phakathi kwebanga elithile lapho izimpahla zithunyelwa.. Uma umsebenzisi elungisa imvamisa yesithumeli, okuhambisanayo i-amplifier yamandla, I-antenna ehambisayo kanye ne-receiver antenna kufanele futhi kulungiswe kufrikhwensi efanayo, futhi laba basebenzisi badinga ukulungiswa. Uma kungenjalo, kuzokwenza ukuthi imvamisa yesidlulisi sevidiyo esingenantambo sihluke kumafrikhwensi wothi, ukwenza ukwamukela kube nzima. Ngakho-ke sicela uqiniseke ukuthi wazisa imvamisa efanele oyidingayo ngaphambi kokufaka i-oda.
Uma kungokokuphepha noma ukugcinwa kuyimfihlo, ungakwazi sebenzisa i-encryption kanye ne-decryption imisebenzi ye-transmitter nomamukeli, okungaqinisekisa ukuthi ukudluliswa kwevidiyo yakho kuyimfihlo. .
Yebo, wonke umkhiqizo wethu amapharamitha kungenziwa egcizelele ngokwezidingo zekhasimende. Uma unesicelo esikhethekile, sicela usazise ngesixhumanisi esingezansi.
