How can you keep a high rise building safe? There are many ways you can do. It includes controlling the access points to different floor levels, ensuring that elevators access are given to tenants only, installing video surveillance as well as external video surveillance. This will allow your team to see who keeps on coming inside the building. It will also allow them to see suspicious people especially if you have an identity security software installed on your system. So, before they make any action, your security team can prevent them from doing it. Yet, you must not be abrupt in interrogating anybody who seemed suspicious.
