If you're feeling adventurous you could get a little Rasberry Pi PC and install an operating system like NOOBS or Ubuntu (my favorite) on it. Then you could SSH to your router, webcam, etc. It doesn't require a screen once you've got it setup and running. It's not very complicated. About 50 bucks.
I've left my old junker Dell (work) laptop in my car continuously for years and it never seemed to be bothered by the cold. In fact they love being cold. I'm sure it was subject to below zero temps many times. I couldn't kill the thing. I wouldn't be concerned about leaving an old laptop running all winter. I'd just set the hard drive to spin down after inactivity. If you're worried about it bursting into flames, just stick it inside the oven. I've got old laptops stacked up like cord wood.
