wireless cctv cameras is what they need

I really get annoyed every morning when I heard complains from the PCA’S at work. They seems like stabbing each others. Maybe the management really needs to add some more wireless cctv cameras to monitor each workers, especially those ones who worked at night. They seems like not really doing their job and yet complains a lot with their other co-worker. In that case they will know how’s really not doing their job during their duties.
