Description:

HCL536 Video Data Link was designed for video data wireless transmission with two- way wireless data link. It works at 800MHz or 1.4GHz bands, with frequency hopping spread spectrum automatic technology (FHSS) to make sure better stability signal communication.

Specifications:

Wireless Networking with HCL536:

HCL536 video data link supports 2 operating modes: Access Node or Central Node.

It can be managed through web UI. HCL536 supports features of maximum 16 Access Nodes connected to a Central Node. All nodes are in the same wireless local area network and share the entire transmission bandwidth (maximum 30 Mbps @ 20 MHz throughput).

The data from the central node to the access node is referred to as downlink, while the data from the access node to the central node is called uplink. The ratio of uplink and downlink data streams can be controlled through the Web UI. When using HCL536 for point-to-point transmission, the uplink and downlink data will share the entire transmission bandwidth (maximum 30Mbps @ 20MHz transmission rate).

HCL536 video data link supports networking mode: Point -to-Point, Point-to-Multipoint, Relay, and Mesh (specify mesh version when make an order).

FAQ

Q1. It seems to support IP camera, but I want HDMI or SDI video input?

A: Yes, the default video input is IP RJ45 Ethernet port, if your camera only has HDMI, SDI, AHD or AV output, we suggest to buy our mini encoder device to encode the video 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 HDMI monitor, you can also buy our decoder device to convert the digital data back into HDMI video and audio signals.

Q2. For the 800MHz and 1.4G band? Which one would be better?

A: If your local area has DVB-T or DVB-T2 digital television signal, and 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, the transmitter antennas are pointing down to send the signal to the ground. So 1.4G frequency effects on GPS is negligible.

Q3. Does it support using multiple cameras on the transmitter to only one receiver? For example, use 3 IP cameras on the transmitter.

A: 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.

Q4. Does the transmitter on the air give failsafe command to the flight controller when the connection between air and ground will be lost?

A: 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:

Q5. Can the transmitter and receiver be interchanged for use with change in the setting?

A:Yes, The difference between the transmitter (on the drone ) and receiver (on the ground) is:

1. Device type: transmitter is the access node and the 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.
