When it comes to many industries, there is a need to have monitored entrances for exclusive personnel. Access control systems tend to be a great solution for those properties, but what about when a visitor arrives? They are unable to enter the premises, though it is necessary for them to communicate their need for entry. In order to make it in, they require a solution where they can present their identity, and be granted access. An audio intercom system can be a wise choice as it allows for easy communication with the press of a button. This is a viable option for many businesses and industries, but can open up some security concerns. Without the ability to actually see the individual, you have to trust their word for who they are. With the incorporation of a video intercom system, you can have full monitoring capabilities of the entrance, and can see who the person is who is attempting to gain entry. This makes for a safer work environment, and also alleviates the stress of any unwanted visitors entering the building.
