They have banned parental recordings because we have a child who is on a child protection order so it needs to be confidential
Thats a good thing, sad for other parents, but it is the right thing for the school to do to protect a child.
It does annoy me when 'no cameras' are used in a blanket scenario though.
DD was in a dance show this weekend. I took a couple of photos of her with my phone, and started to take a video when she was doing her solo.
One of the theatre staff told me to stop. I asked why and she said that cameras and videos weren't allowed.
I asked why and she said "well isn't that obvious?" really sarcastically.
I said no, and asked who the woman at the front with the zoom lense was then, seeing as she had taken a number of shots of MY daughter.
She said she was a member of staff and that the shots were going to be used as promotional material and also sold to parents. She said that everyone taking part had given permission for photos to be taken.
So I just stood there smiling and waiting for the penny to drop....
Unfortunately by the time it did I was too late to film DD and the woman just hurried off after saying "thats different" 
I dodn't really care that much - I've probably got hours of videos of DD dancing, but that woman did make me chuckle
