Do I need to inform staff where the cameras are or can I just put some signage up stating that CCTV is in operation in this office?
Think you are not in the same country as I am but just for fun and intrest tell about Norway,
1. Secret camera surveillance is forbidden! (That will say that you are not allowed to have any cameras, without having a sign saying that CCTV is in operation.
2. It is illigal to have a CCTV sign up if you do not have any real CCTV surveillance.
3. It is not to have Dummy/broken cameras in "use".
4. It is allowed to have hidden cameras so long it is a sign saying CCTV is in operation.
So for a retailer, you would need to inform employees about the CCTV and they can ask to see the camera point of view. You need to put at least a sign at the entrance telling customers that CCTV is in use. You can not store the video files more then 7 days. After that you need to delete them or hand them over to the police if you want them to use them in a ongoing criminal case. (Post office and Banks and some other high risk/high security places can store for 30 days).
You are not allowed to use CCTV in public places like outside on the street etc, only Police can after they have filed a request that have been approved. There is not allowed to use Audio in any way except at Bank/Post office. You are not allowed to film in places where people would excpet to find privacy for instance Toilets, dressing room, showers, swimming pools, nightclubs and bar's.
Probably not much useful here but ....
