Q2: For 15km, should I use a 10W PA power amplifier inside?
A2: 10W PA supports up to 150km, 10W PA draadloze videozender en -ontvanger 110 km echte testvideo. 15km met behulp van een 2W PA-eindversterker is voldoende, op onze testvideo, het ondersteunt 27 km-30 km, Controleer de onderstaande link voor testvideodetails.

Q3: Is your price on the base of one node or one pair?
A3: Normaal gesproken is de offerte voor draadloze zenders en ontvangers op twee manieren gebaseerd op één knooppunt, u kunt zich bij veel knooppunten aansluiten, zoals een computer zich bij een netwerk aansluit. Als u één zender en één ontvanger nodig heeft, de eenheidsprijs moet het dubbele zijn.
Q4: What kind of video quality and speed?
A4: De draadloze videozender en -ontvanger met ethernetpoort ondersteunen een 1080P60 IP-camera, en de maximale snelheid ondersteunt 20Mb bps.
V5: How about the delay and radio band?
A5: De vertraging bedraagt 26 ~ 70 ms (milliseconde) uit onze testvideo van 110 km, van de ethernetpoort van de zender naar de ethernetpoort van de ontvanger, getest door Ping-opdracht in het Windows-computersysteem.
De radioband kan kiezen uit 800Mhz, 1.4Ghz, of 2,4 GHz, because of 800Mhz is the digital tv standard frequency range and 2.4Ghz are some wifi frequency range. So our wireless video transmitter and receiver’s default frequency range are 1.4Ghz.
V6: Why are some one-way wireless video transmitters and receivers much cheaper than two-way?
A6: Because one-way wireless video transmission systems are only video downloads from the transmitter to the receiver, they can not upload the drone control command or PTZ camera control command from the receiver to the transmitter and camera, so the function is simple and the price is cheaper.
V7: Does your model support, a 10-15km transmission distance, open air, van lucht naar grond, multi-camera to one single monitor, it is better for outdoor use?
A7: TX900-2W-30km supports the demand you mentioned in the above question.
Q8: Does it support 10 transmitters and 10 receivers working together?
A7: For TX900-2W-30km support 10 transmitters with 10 camera's, you do not need 10 receivers and 10 monitors, you can use one TX900-2W-30km as the receiver or center receiver, this type we called to star connection network.
Q9: If I want to control the signal pin (GPIO pin High or Low, or common 1 ), what kind of models do you recommend?
A9: If you want to control the signal at the transmitter from the receiver by somebody, this is the typical application of the two-way wireless video data link, TX900-2W-30km is powerful on this control application. Because it can not only download the video and data from the transmitter to the receiver but also can transfer the receiver’s control command to the receiver, there are two ethernet ports and three RS232 ports.
