Privacy invasion and Neighbour CCTV

[WillMH]

Our house backs onto the side access of another house. New owners have spent the last year renovating the house and building a rear extension. In the summer we noticed that they had added a CCTV camera to the far corner of the rear extension which is directly filiming the whole back of our house - rear garden, as well as inside the house (through glazed back doors). We've asked them to reposition the camera but they refuse. We have children and it feels like a real invasion of privacy to have this camera, with its green light showing it is operating, permanently pointed at us.
I contacted the ICO and all they can do is send him a letter urging him to move it. Neighbour has also consulted ICO website so knows where they stand.They could easily reposition cameras to other locations which would satisfy their security concerns and not invade our privacy but they are not willing to as they have just installed it all and renovated the entire property so this would involve rewiring.
Do we have any other action we can take? Do we have no right to privacy for ourself and particularly our children?

Can you position something on your side of the fence that blocks their view. Like a trellis panel.

I used to live opposite two houses, one of which had extended to the side and so their new window on their new extension was now 8ft away from their neighbour's existing side window (which was their bathroom). So the neighbours with the old/existing window rigged up what looked like a normal 5ft by 5ft fence panel on two massive poles and put it up in between their houses, on their land.

Is something like that an option. Something temporary that they can't complain about. Even one of those patio sails?

erect a tall washing line. Hang your tarpaulin on it to dry (or you can buy a piece of camo netting).

Put a scary dummy in your back garden and move it around (and remove it from time to time). When they ask what it is tilt your head and look concerned.

Like others have suggested trellis or a large quick going plant.

Send them a SAR every day

They should have the option to blur out where it records your property, so they may not have to reposition IF they can do this. We can on ours but our neighbours are happy for us to record where ours over look their property. They should have as a curtesy, at least notified you so you could ask they could do this.

Nice big fence panel with a thoughtful picture on their side.

Our cameras appear to be pointing into our neighbours back garden but in fact we've blocked out their property - which most cctv has the ability to do. So we aren't actually filming their patio. We did knock and tell them that though, and showed them our footage.

They can't have it pointing directly into your property but if its point mainly into there's area their is very little you can do . some camera CCTV systems have a blanking out area facility so it can't record neighboring property but looks like it is .
Council environmental service would be able to advise but its dependent of interpretation of the rules of each council .
