I have two models of iON.
I did a review here: http://chadkovac.com/2016/02/21/new-ion-cameras-installed-tested-reviewed/
I’m still a fan for the price and at $40 instead of $99 which I paid originally, these are a great deal.
Does this have a microphone input?
Features say yes:
Audio – Built-in, high-quality microphone; AAC compression, automatic gain control
