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. A door locksmith can do it.
As has been indicated, a door entry system can be installed in buildings or building complexes of various sizes. 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.
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.
Door Entry Systems
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.
For large organizations, key card or keypad systems may be more appropriate as they allow more independence for the visitor. 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. 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. This is known as electronic lock system. (Car Door Entry Systems)
