The casing of our devices was made of metal, so the inside circuit will not be interfered by other wireless signal. Normally the power of walkie talkie is always huge which could effect the transmission if the HDMI/SDI cable shielding properties is not good. Please try to replace an HDMI/SDI cable which has a good ability of anti-interference, and keep the walkie talkie at least 1m away from the cable.
