Can my employer make me pay for a till shortage?

I have worked for my employer for 2 years in England.

My neighbour recently installed a CCTV camera that seems to point directly at my front door as well as part of the shared path.

They say it’s for security, but it feels like it records everyone coming and going from my home.

Is this allowed in England, or are there rules about where private CCTV cameras can point?
