What are some of the most common screw ups to avoid when installing an access control or door entry system? In this article, we’ll look at some of the most common mistakes engineers make when installing access control and door entry systems.

What is a ground loop error?
A common mistake is to ground the shielding at both ends of the data cable. If the two grounds do not have the same potential, current can flow through the shielding, distorting the signals in unpredictable ways and causing video application malfunctions; this is known as a ground loop.

How do I conceal the cables for my access control and door entry systems?
For aesthetic reasons, it is always preferable to hide cabling beneath floors, above ceilings, or beneath wall plaster, but this is not always possible. If it is difficult to conceal the cables, electric junction boxes can be used.

What factors should be taken into account when installing the access control and door entry components?
The manufacturer’s specifications must be followed when mounting the components (attaching them to walls, racks, doors, and door frames).
The diagram below illustrates typical electrical component locations in a door.
