Yes if it could done surreptitiously this would be better, but I would rather not get a beating, seriously though you should be careful. Is there not anyone who knows someone with a flat overlooking the area? Or, a shop with a view who wouldn't mind some surveillance? A long zoom lens from inside a far away window would be best, well out of way and sight.
Or...
Slightly more elaborate may be a hidden camera hat? (not like the one in simpsons)
