You try finding a cheapish, 2 or 3 Mpix IP camera with a sensible field of view (ie not more than about 70 deg) that can FTP upload a configurable but static filename still image on a regular basis say every 15 minutes.
Not many can these days, they are all geared towards remote monitoring on an iThingy or only doing things on an "alarm" trigger, like motion detect.
The HIK Vision only fails on the static filename(*). The Vivotek IP8131 ought to pass but seems to be made of unobtainium, it's also only 1 Mpixel.
(*) A thought has just struck me I wonder if the HIK Vision camera has any command line SQL tools that could be used to change the db entries. It has SSH access...
