My work involved using expensive cameras to monitor remote sites and I was an early adopter of commercial off the shelf (COTS) systems for home use. Since about 2000 I've had (and still have) Foscam, Netgear, Reolink, several Trail cams but for the last 3 years a LOT (about 30) of Wyze cams deployed at 3 residences.
For the OP's situation a few good trail cams would be best for now.
One of the problems with most of the cameras was cost and software. Up until Wyze, cameras cost about $100 and up and problems with software were frequent and rarely fixed. Wyze changed that.
They had a $20 camera with a responsive customer support and a group of programmers that would change the software for the better FREQUENTLY.
But that also is changing. Camera prices jumped this spring (now $30@) and because Wyze now sells so many lines, from Vacuums to doorlocks, their focus has changed.
Their most recent camera, the V3 has pretty fair low light performance, is easy to set up, is weather proof enough to mount outside without separate enclosure, and works well with 128GB SD cards. I get about 2 weeks of CONTINUOUS recording (24 hours/day) on a 128GB SD card.
