Technology has advanced so quickly in recent decades that what once seemed part of science fiction is now very much part of real life. This is particularly true when it comes to modern alarm systems, which make good use of computer, light sensor and radio frequency technologies to make homes and businesses more secure. The manufacturers of such security alarms offer a range of products to suit both the commercial and the residential markets. For example, Scantronic has long been a leader in the industry and provide proximity readers as part of their most modern models. The same can be said of other brands, like Pyronix, which have recognised the advantages connected with such technology. Proximity readers take out the hassle of keying in codes when entering, and sometimes exiting, a premises. Instead, getting into a building is now a simple case of swiping or showing a card or tag to a reader. The reader emits a constant radio frequency signal that is absorbed by the proximity card, which triggers the transmission of a unique identity code to the reader itself. The general advantages of such a system include the facts that no reading mechanism and no reading heads are needed. Instead, the low level signal ensures that the triggering device is never actually off. The fact that the access code is unique and housed in the chip within the card or tag means that duplication is virtually impossible. Not only that, but because the signal can move through thin materials, this system can also be concealed behind a wall or plastic casing. Of course, the system was designed to cater for hundreds of personnel and prevent the clogging up of entry points in a commercial building. They normally operate using a computer software package, where the access codes are stored and can be grouped so as to allow specific staff access to specific areas. However, the advances in technology now mean that a pc is no longer necessary for the reader to know who to give access to or who not to, making it suitable for home security systems too. This technology was never simply a neat trick used by companies to impress clients, although doubtless when it first came out it was eye catching. There are very legitimate reasons for using it, with industrial security the key one. The technology has been used for well over a decade in laboratories, and research and development departments, where only certain staff could be privy to the latest developments and discoveries. The capabilities of the system have meant that small companies have been able to make use of it, and not just for security reasons. The system also acts as a clocking in mechanism, noting the time that an employee enters work and when they leave. It can even detect the specific location of staff members within the building at any time. For home security systems, the needs are very different, of course. There is no swell of people trying to enter, and no real need for anyone to know where a family member is within the home at any one time. But, what it can do is remove the need for a person to manually key the alarm code in when they arrive home in order to turn the alarm off. Similarly, when leaving the home, a simple wave of the proximity key can set the alarm, again placing no pressure on the resident to remember the alarm code. Of course, there is always the chance that a proximity tag, which might easily be attached to a keyring, may inadvertently set or unset the alarm. However, the range of the radio frequency can vary, requiring the tag to be held close to the reader, perhaps as close as 2 inches before there is any reaction. A proximity reader is not available in every security alarm systems, but its inclusion in systems is no longer a strange thing, even for the home. Amongst the leading manufacturers to include them are Scantronic, whose 32 zone 9752EN model is perfect example for commercial properties. The six digit PIN security code can be used, but it includes an integral electronic reader also. Another manufacturer to include the technology is Pyronix, whose PCX SMS model can handle up to 26 zones and sends an sms to the property owner should there be any security breach. It is ideal for commerical properties, but can also be effective to on residential buildings.
