Best camera for internal use/watching dog

[Phillycheesesteak]

I've got a clever dog camera but its crap. It's always disconnecting. I basically need a camera that I can check while in work and on 4g. Any recommendations?

My dB bought an indoor camera for £30 from Amazon, it can move and you can talk through it, so talk to your dog. My dB bought this for my elderly mother to keep an eye on her and talk to her rather than call her.

Neos cameras.
I have one in the kitchen for my dog. Brilliant little cameras and only £25

Yi dome camera. It spins 360° as well as you being able to talk to your dog.
