5) Access control with computer feedback
If within your organization you control more than just a few fob- or card-readers, then it may be suitable to have them administered centrally by wiring all readers to feed back to a central computer. This will make it very easy to add or delete fobs/cards or, for example, to set them up to work at certain times on certain readers only. While the installation and cabling tend to be involved, the end-result is usually incredibly well received.
Intercom Systems
Intercom systems are a ubiquitous feature of both residential and commercial premises. If you need to know who is knocking on your door, then an intercom system is a must.
Depending on the end-user's requirements, intercom systems can be large versions for many users:

This is a flush-mounted intercom system, where the main part of the equipment is sunk into the wall.
Or they can be small, single-user units:

In this case, the entire unit would be fitted onto the wall - this is a surface-mounted intercom system.

Intercom systems are audio-only most of the time. Audio systems outnumber video systems by a factor of 20.
For commercial installations, intercom systems are frequently combined with other means of access control, such as a keypad or a fob-reader:

The intercom is for visitors, whereas staff will be able to easily get in via the keypad.
As a rule of thumb, intercom systems can have a trouble-free life-expectancy of between 5 and 10 years. As there aren't any moving parts, they don't usually need a service contract.
