Some security systems only work when the break-in has been accomplished and are more about alerting security staff or police and identifying the criminals. They may make use of an infrared camera or some other kind of surveillance camera for this purpose.

But for a homeowner who is interested in preventing a break-in and worried about opening the door to a stranger, a closed circuit monitoring system (CCTV) could be the answer. There is no need to open a door without first knowing who is on the other side with a CCTV camera installed. You can also add automatic lock controls and an intercom for extra protection.

Dvr stand-alone security camera systems provide simultaneous recording and playback capabilities. These security camera systems have certain benefits, but they are not suitable for all needs. Usually at least one camera is needed as a minimum while you also need something, such as a TV or a monitor, to play back the images on. If you want to use your TV then it will need to have ‘video in' jacks. If you want to record images you will need a VCR.

When choosing a CCTV dvr unit you can get a black and white or colour camera, but the correct camera lens is of prime importance. An auto-iris lens is a good general one used for varying light conditions. Manual and power zoon lenses are also available.

While you may feel that multiple cameras are necessary to watch each entry or exit area, having more than one camera means that your security system will be more complex. It does not need to run continuously, though. It can be set to only start when motion is detected.

1. The statistical study of biological phenomena.

2. The measurement of physical characteristics, such as fingerprints, DNA, or retinal patterns, for use in verifying the identity of individuals.

September the 11th, 2001 saw the United States shaken to it's very foundation. We watched the towers fall and suddenly we all felt threatened.

Security whether it be personal, industrial or global became, and still is a massive issue. With all these perceived threats on our lives, family, assets, identity etc what is the best way to make ourselves feel secure?

Traditionally security comes with "something" we have to carry or remember. Passwords, keys, cards, badges etc. The problems with these systems are numerous. "I forgot my password", "I forgot my key", "My key got stolen", "I need to update my password" etc.

Nature in its wisdom gave ALL of us the best ever security device, Biometrics. Whether it be our fingerprints, vein patterns, habits, behavior etc every one of us have unique identifiers that biometric systems can record and use to validate us to be who we claim to be.

In a nutshell Biometric systems employ a 4 stage process.

1. Capture. During enrollment, the system captures the biometric sample to be used. Fingerprint, eye scan, etc

2. Extraction. The system extracts the uniqueness out of the captured sample and turns it into a biometric template via a mathematical algorithm.

3. Comparison. When the user attempts to gain access in the future, the new sample is compared to all the old samples in the system.

4. Matching. The system will find a match and grant access or deny access when no match is found.

That is basically it. How long does all this take? Depending on the amount of users in the system anywhere up to a second? Less users = faster access.

The current biometric systems have a rejection rate of

So how does all this pertain to the average Joe out there?

Biometric technology is fast becoming more mainstream as a security measure for everyday people. No longer is it the super expensive system of the wealthy few but it's now abundant and affordable to you and I.

You can secure your PC data at the mouse, at the flash drive even at the door to the room with the PC. You can secure your car to the point that no one can steal it. The car's ignition system is encrypted and requires a valid fingerprint to start.

Let's assume someone absolutely MUST have your car and decides to steal your finger; the system will not recognize it. Biometric systems require a living sample to do the comparison and match stages.

The future of security is already here.
