The property management staff, I think I want to be responsible for the safety of the area inside, if the area inside the security protection, residents living can be assured, recently I have been thinking, how to strengthen the safety, then I thought of a way, that is the area inside to install some Marine CCTV Marine CCTV, I think this is very good, but now there are some corner inside the parking lot we do are not in place, we can then install some Marine CCTV in those places, so maybe some security will be more, but I think this kind of Marine or CCTV well, installed in the area inside, no matter which corner can see, is really good.
