Can you explain your situation a little more?
No, that is not an offence I'm afraid.
There are offences in things like voyeurism but then you have to film somebody doing something really private like using a bathroom.
There is no offence in evidence gathering although actually photographs do not prove barking.
In any event, unless you are not allowed a dog at the property, the fact that you have a dog does not amount to a noise nuisance.
All dogs bark especially when somebody is at their window. To amount to a bark nuisance it has to be consistent for more than 20 minutes at a time.
Can I clarify anything for you?
