5442 s3 equivalent with two way audio?

Not equal in image quality*, but the 3449 PV-PRO series has a pretty good mic/speaker setup with true two way talk


* search around the forum you’ll find some reviews. It has its issues and because of an inadequate sensor it doesn’t have the image quality of the 5442 series, but it does have the audio features and onboard white LEDs that make it acceptable in certain scenes, especially if you can give it added external light

Same as Andy’s Color-4M series

I think DIY but haven’t attempted it myself.

There may be other factors in that true two way talk involves more than just the hardware. You get the walkie talkie effect
