Even if a building has gates, locks, cameras, and alarm systems, it's not entirely safe from security issues. After all, anyone who's determined to break inside the facility to make mischief can find ways to climb up the gate and open the lock even without a key. State-of-the-art cameras and alarm systems are quite tricky to bypass, but it does not necessarily mean it's impossible to do so.
Hiring a security officer is necessary if an owner or manager of an establishment really wants to prevent anyone from trespassing. With trained personnel guarding the whole facility, it would be almost impossible for anyone to break into the building's perimeter. If they manage to do so by a slim chance, the security officers can check the cameras and apprehend the trespasser before they can escape.
