Remote HD camera, how hard can it be?

Internet is full of apps like Alfredcamera etc for using a mobile as a surveillance camera. Easy to use, but the videos/pictures are lousy, blurry 1080 res. Cant even read a car license plate with those.

I want to set up a mobile at a house(no WiFi) which is empty most of the year and occasionally do a check .
I dont need any vidoes with alarm and motion detection. I simply need to be able to take sharp HD pictures in original mobile quality, and have them sendt back to my main mobile or PC. How hard can that be in 2021? Well I havn't found any apps yet that can do this. Someone know?.

 

Thanks man,
..or if I instead use two mobiles: No.1 sends a command - No.2 takes picture and respond with a MMS? That's all I want.

Yes I've heard about this Tasker for various remote control actions. I will have to check it out.
