Monitor the entry points in your home or business. With an access control system, you can manage who enters your property by utilizing a keypad, a key fob, or an access card. By using such items, you don't have to change locks every so often. You grant access only to certain people like your staff. If needed, you can also grant temporary access to vendors. You may also set the access time if you want to deny access to certain people for a particular time. This reduces the cost of reconfiguring the network for when employees leave at the end of their shift, or they leave the company for good. If these people insist on trying to gain access, you will get notified by an email, complete with pictures.
