Door Entry Systems: Learn How They Can Protect Your Business or Home

In today’s uncertain economic climate, many businesses and homeowners are worried about the possibility of an increase in crime. As a result of this, they are taking action to ensure the security of their property: a key facet of this is the installation of an effective door entry system.

Door entry systems can be defined as electronic or mechanical systems that control access to a property: as such, they can also be called door security systems or door access systems. Though in the past they have been most commonly installed by large companies or in large-scale residential developments, advances in technology have combined with increased efficiency in mass production methods to ensure that even a homeowner with a modest income can implement some form of door entry system, resulting in an ability to control access to his or her property, and therefore an increased feeling of safety.

As has been indicated, a door entry system can be installed in buildings or building complexes of various sizes. Simplest are the intercom systems that can be installed to protect single properties: these allow the individual homeowner to permit access after either talking to the visitor through an intercom, viewing them via a video screen, or a combination of the two. Next up the scale, low rise systems are appropriate for low rise blocks of domestic properties, or for medium sized company buildings with a number of entry points or offices. Finally, high rise systems are complex systems that allow access control for full-scale high rise housing developments and also large company buildings with multiple offices and entry points, or even sites with a number of company buildings in close proximity to each other.

No matter what size of property is being protected, there are a number of types of door entry system that may be installed. The most basic is a simple intercom system: this allows the resident to talk to the visitor though an intercom. Video entry systems are an extension of intercom systems which add the functionality of allowing the resident to observe the visitor, via a handily placed video screen.

For large organisations, keycard or keypad systems may be more appropriate as they allow more independence for the visitor: rather than relying on the resident to grant entry, access may be gained by punching a number into a keypad or swiping a card through a card reader. Not only does this leave the resident free to do other things rather than monitor access, the latter especially can allow varying levels of access, granting entry to some parts of a building but denying it to others. In this way different groups of visitors or employees can be controlled in their movement throughout a building with a minimum of fuss.

A new development in this field is the increased implementation of proximity sensors. Instead of remembering a code or carrying a keycard, visitors simply carry an object that grants access. When the visitor or employee comes close to the proximity sensor, it automatically detects the object being carried and opens the door. This method is especially useful in loading bays where it is desirable that drivers can gain access without leaving their vehicles, for instance in high security areas or in extreme environments.
