If you consider alternatives beyond out-of-the-shelf, I’d recommend your own DIY IP camera. A Raspberry Pi (or something similar, such as Orange Pi), an IR camera module, an UPS and a protective shell case are the minimal hardware requirements for a cheap camera built by yourself. You’ll have total control over the software, you’ll be allowed to choose the OS, the software, every aspect of the camera, something that’s not possible with out-of-the-shelf IP cameras.
I sleep. It’s the closest to be distant from the boredom of existence.
