Collar camera suggestions for inside-outside cat?

I try to keep my cat inside for the most part, but before I had her, she was allowed outside anytime she wanted so she’s gotten really good at sneaking out when I turn my head for even just a sliver of a second. There have been a couple times where she’s been gone for a couple days and I’ve been worried and I was wondering if anyone knew of a camera I could buy to put on her collar for when this inevitably happens again? I don’t want something that films and you have to get the footage from the camera, I’m wanting something that offers live footage that I can access through my phone, kinda like a ring camera. Any suggestions?
