FAQs
This model is our lowest latency for the drone wireless video transmitter and receiver.
It supports the lowest 28-millisecond latency. (Not including the camera and monitor display time)
COFDM-912T, CVBS RCA 720P Video Input, 200~400 millisecond.
COFDM-908T: HDMI input, 200~300 millisecond.
Vcan1729: HDMI input, 20~40 millisecond. suitable for drone.
The 1729 model is ultra-low latency, which is very suitable for drones. It can detect obstacles in time, such as houses, trees, wires, etc., and avoid them in the shortest time. Many drone factories in China have adopted this video transceiver system.
