  • Controlled via Web UI or Serial UART for easy management and configuration.
  • Features 2 Ethernet and 3 UART data links for versatile connectivity options.
  • Long transmission distance of up to 150km with 10W RF power for reliable performance.
  • Operates at 800MHz or 1.4GHz bands with FHSS technology for stable signal communication.
  • Supports AES128 encryption for secure data transmission.
  • Compact and lightweight design (252g) with dimensions of 131.9 × 67.7 × 28mm for easy integration.
FAQ:
  • Can I use a camera with HDMI or SDI output with this transmitter?
    Yes, but you will need a mini encoder to convert HDMI, SDI, AHD, or AV signals into digital data for transmission. At the receiver end, a decoder can convert the data back to HDMI if needed.
  • Which frequency band should I choose, 800MHz or 1.4GHz?
    If your area has DVB-T or DVB-T2 signals (170-860MHz), the 1.4GHz band is recommended. Additionally, 1.4GHz has minimal interference with GPS signals.
  • Does this transmitter support multiple cameras on one receiver?
    Yes, you can connect multiple IP cameras using a net hub or NVR with HDMI output, then encode the signal for transmission to a single receiver.
  • Does the transmitter send failsafe commands to the flight controller if the connection is lost?
    No, the serial port is transparent and does not send failsafe commands. However, the LED indicators show link status (weak, medium, or strong) to help you monitor connectivity.
  • Can the air unit and ground unit be interchanged?
    No, the air unit (transmitter) and ground unit (receiver) have different roles and rate ratios for optimal performance, especially over long distances.
  • Does it support 4K video transmission?
    Yes, but the transmission range will be shorter compared to 1080P video.
  • What is the difference between HCL536 and HCL551 models?
    The HCL551 supports a longer transmission distance (up to 150km) compared to the HCL536 (up to 100km), due to its higher power capabilities.
