UHF/ L bands Network 150km UAV Video Transmitter With Frequency Hopping Spread Spectrum

Yes, the default video input is IP RJ45 Ethernet port. If your camera only has HDMI, SDI, AHD or AV output, you need to buy our mini encoder device to encode the video and audio signal into digital data for transmission. At the receiver end, you can connect it directly to your computer or NVR. If you want to output to an HDMI monitor, you can also buy our decoder device to convert the digital data back into HDMI video and audio signals.

If your area has a DVB-T or DVB-T2 digital television signal, the TV frequency range is 170-860Mhz, so choose 1.4G would be better. Moreover, GPS antenna receives the GPS signal and the GPS direction on the drone is up, and our transmitter antenna is pointing down to send the signal to the ground. So the 1.4G frequency effect on GPS is negligible.

Yes, it supports. There are two solutions for the multiple cameras on transmitter to one receiver:

1. 4 IP cameras → Net Hub → Transmitter ↔ Receiver → Computer Screen
2. 4 IP cameras → NVR HDMI output → HDMI encoder IP output → Transmitter ↔ Receiver → computer screen.

The serial port of our wireless video transmission link is transparent, no data is actively sent to the flight controller. This is controlled by the ground station. It won't send failsafe command, but you can see the link working status led from the signal indicator as below:

Flight controller doesn't get the information, but you can see the link status LED light. If it is Orange or Red, you should control the UAV back in advance. You can also get the RSSI values from below window.

The difference between the air unit (transmitter) and ground unit (receiver) is:

1. Device type: Air unit (transmitter) is the access node and the ground unit (receiver) is the central node.
2. Rate ratio of the downlink and up link. Over 30km, the best rate ratio is 4:1 or 3:2.

Yes, it supports 4K video, but the transmission range would be shorter than that of 1080P.

The main difference is in the power. HCL551 supports a transmission distance up to 150 km, while HCL536 only supports a transmission distance up to 100 km.
