Wifi camera to monitor temperature guages

I know there are a lot of cheap security / pet cameras out there, but I’m hoping to find a recommendation specifically for monitoring gauges - so doesn’t need audio or HD. Doesn’t even need 30 fps. Just want to look at a temp gauge remotely so I don’t have to come into my shop just to see the status of my brew kettle.

We do long processing times, so it would be a huge stress and time saver if I could look at it any time I wanted.

Does anyone have a camera recommendation?
