2 way audio setup

[e007]

Hi.

I still can't understand the pricing of Axis accessories. I don't want to pay as much for the camera for microphone.
Could these possibly work outdoor?

Mini Microphone Handsfree Clip 3.5mm Microphone PC For PC | eBay
or New Mini 3.5mm Microphone Outdoor Stereo Microphone Notebook Notebook Phone 2017 | eBay with longer cable.

Also, what would you recommend for the speaker? The temperature can drop below 30 degrees Celsius.

Thanks
