KanexPro ECOAX4 Reviews
Works as Intended

Purchased this to add a wireless 3.5mm mic to a PTZ camera that outputs video through HDMI. The camera has a 3.5mm audio in, but sounded like garbage. This fixed that. If anyone is wondering: I did PTZ HDMI to the KanexPro, Wireless mic to the 3.5mm Line In, HDMI from the KanexPro to a deck recorder. This embeds the audio to HMDI without any lip-sync issues that I've noticed. Sounds decent for the price. Will be running this on a 24/7 PTZ camera. Hopefully it holds up.
