Laser Home Security - Inside, Outside, All Around Your Home

Laser Home Security - Inside, Outside, All Around Your Home
By David Faulkner

Laser home security alarms, which create beams of laser light, can be installed either around your homes exterior perimeter or in your homes’ interior rooms. If installed on your home’s exterior, the alarms can be positioned at set intervals high enough above ground level to give your home’s perimeter complete protecting from intruders by sounding an alarm when the beam of light is penetrated.

Exterior Laser Home Security

Laser home security perimeter alarms are among the most costly home security equipment available, but are popular because they can be concealed beneath the homes shrubbery and are easy to arm and disarm. They will neither harm the lawn or other landscaping around a home, nor damage any lawn ornaments or furniture.

Laser home security perimeter alarms are also ideal for use around the perimeters of swimming pools, where they can be set to project light beams between one and two feet above ground level, and sound an alarm whenever a small child approaches the pool.

Like other security alarms, laser home security systems can be installed so that they alert local police as soon as their light beams are disturbed and the alarm sounds. Having this feature is becoming essential; the increasing numbers of car alarms which sound with regularity have desensitized people to the sound of an alarm. So you can’t depend on your neighbors to notify the police if your laser home security alarm should be triggered in your absence.

Interior Laser Home Security

You can purchase an interior laser home security device capable of covering a room of up to eleven hundred square feet with its sensors, and signaling its master control unit when its light beam is broken. The control unity will then sound an alarm; if you pay a modest monthly fee for a monitoring service, they will contact the police for you. One of these systems has a device to prevent your pets from unnecessarily tripping the alarm.

Most interior laser home security systems are compact and very simple to install; they will ply into your regular telephone jacks and power outlets, and can be connected to the master alarm control and to each other with a remote. The monitoring company will first contact the homeowner in the event of a laser home security alarm sounding, and then contact law enforcement if necessary.

Most laser home security systems come with a one-year warranty on parts and labor, which will be upgraded to a lifetime warranty for those who use the monitoring systems. And they have backup batteries which keep them functional even during power failures.

Biometric Door Locks: Secure, Reliable, Comfy

Biometric Door Locks: Secure, Reliable, Comfy

Gone are the days of carrying bunch of keys for opening doors. Gone are the days of keeping separate keys for separate locks. Now you would be able to unlock all the doors and cases without the help of any key. The idea is not new and has been in use for quite some time but slowly and steadily it is becoming popular and coming in people's eye. Right! We are talking about biometric door locks.

Biometric locks provide an entirely new level of interface with extreme ease & security. The most noticeable benefit is getting rid of carrying cumbersome keys. It also mitigates a range of problems associated with PIN, standard key, RFID, magnetic stripe cards, etc., while providing new levels of ease. Biometric door locks identify the authorized people on the basis of their biometric properties, already fed earlier into the system. The unique biometric characteristics of individuals allow only correct users to enter the system.

For quite some time the use of biometric access systems, particularly biometric door locks have been plagued by two flaws. First one has been the high cost of these devices in order to achieve accurate performance that put them out of the general consumer range. The second problem has been the visual design characteristics. But in recent years biometric device manufacturers have been able to sort out both these flaws. You can now find a range of biometric access devices in the market at an affordable rate.

Types of Biometric Technology
A number of identification technologies have been used by the biometric door locks manufacturers, such as fingerprint recognition technology, face recognition technology, voice recognition technology, iris recognition technology, etc. Each of these technologies work on some type of unique and individual biometric properties that we inherit. In this way one can't copy or duplicate one's unique identification like the password and access card, ultimately enhancing the security.

Unlocking Doors with Eyes
Now open doors with your eyes! You might have seen it many times in sci-fi movies. But the fiction has been changed to reality. Researchers from Queensland University of Technology's faculty of Built Environment and Engineering, has achieved sorting out one of the final obstacles to the everyday application of iris scanning technology. Already being used, this technology will become the part of our daily life in coming decade.

Like fingerprint every individual iris is unique and even the iris pattern of the left and right eye of the same person differs from each other. The iris pattern is fixed throughout a person's lifetime. Iris recognition confirms the identity of a person based on who the person is instead of what the person possesses, such as an ID card or password.
