Looking at Google images for Berlin Zoo fence, it appears there is a fence of vertical iron railings around 10 feet high - does this go all the way around? Or would there be something different, eg a wall, on the side nearest the Tiergarten? I can't tell from Google satellite images.
I'm assuming the zoo has security cameras installed - can anyone confirm this?
Would there be passers-by in the area, even at that time of night?
I'd like my characters to climb the fence and wander around for a while before they realise they've been seen by security cameras, which happens just before a couple of security guards turn up. Does this sound feasible?
Thanks in advance!
