Alarm and cctv system regulation

Good day everyone! Just wanted to hop on and ask a quick question. Recently I've been thinking of installing some alarm systems and video surveillance systems in my office building. Are there any particular regulations against this or will I need to have a permit or something to do so? 

There are video cameras everywhere, in the street, in the supermarkets, in shops and all over the airport. No doubt in Spain you will need some sort of permit that will be just ink on paper to extract money from you.

I see, thank you very much!

Well when it comes to commercial buildings, cameras are usually installed around each entrance, it's a pretty normal thing but I do think you need a permit and some paperwork done before. And for your reference, most clients of mine ask for axis cameras with skyrec or network optix vms in such areas.
