ເຄື່ອງສົ່ງສຽງ ແລະເຄື່ອງຮັບສັນຍານວິດີໂອໄຮ້ສາຍສຳລັບກ້ອງໝວກກັນກະທົບ skydriver

hi, I am looking for a system capable of transmitting video and audio from an action cam (HD at least) installed on a skydiver helmet (ເຄື່ອງສົ່ງສັນຍານ) to a tv/laptop in the ground (5km max). Do you have something built in that can work for that? ຂໍຂອບໃຈ
