I'm sure some people have something similar already, but as they vary so wildly in price I wanted to recommend the one I have just bought:
https://www.amazon.co.uk/Clever-Dog-Camera-Monitor-Colour/dp/B019RQNV7Q/
You control it through a phone app, you can watch it live from anywhere as long as you have wi-fi, and it automatically records video if you turn the motion sensor on. It even alerts you if motion is detected, and you can talk to the person at the other end!
Really impressed with it for the price, there are much better ones for more money but for the cost of a loose figure it's really a no brainer.
