FAQ on Biometrics attendance system

 

 

Biometrics is a concept that many may not be familiar with and there are several FAQ on biometrics attendance system.

It helps in authentication and identification of a person based on their characteristics and biometric template to compare with the existing data for recognition.

 

Biometrics is a form of access control that is used for keeping highly secured places safe from unauthorised access.

 

The reference model for identification is first stored in a database later this model is compared with the biometrics data of the person to be authenticated. After the process of authentication the person’s identity is verified.

 

For example:

Are you Mr/Mrs/Miss A?

Biometrics consists of identification system that determines the identity of a person. The biometric identification then captures a biometric data that can used for recognition. It can be a photo, image of fingerprint, voice recording, image of an eye, etc.

This captured information is then compared with all the other stored data in the biometric identification database for a verification.

 

Hence, that is what Biometrics is but that is not enough to answer on the FAQ on Biometric attendance system.

 

Let us look into the major FAQ on Biometrics attendance system for a better clarity.

  • Is fingerprint scanning technology harmful for health?

A very often asked FAQ on Biometrics attendance system.

This question has no evidence to support that it is harmful for health or can impose any negative effects in ones body. It is a non intrusive and simple scanning process for identification and authorisation.

 

  • Does fingerprint scanner secure my identity?

Absolutely, it also enhances your security and privacy by providing a combination of encryption and biometrics. It is process that requires for you to be physically present there to verify your identity unlike keys and access cards or pin codes.

 

  • Can I still login with an injured finger?

Another FAQ on Biometrics attendance system.

In case of a injured finger as long as the outer layer of skin is not badly damaged you will be able to login easily. If a scar remains on the finger it can be used as a unique feature of your identification in the later days to come.

 

  • Can my fingerprint image be duplicated?

No, the fingerprint image is not stored while the minuetia is captured instead and calculated using the algorithm concept. It is then stored as your unique identity which cannot be provided by any other source except your own finger.

 

  • What is the most popular biometrics?

According to the research the most popular biometrics is the fingerprint biometrics. This is due to the less complicated process of a fingerprint identification, it is also much lesser intrusive, the device for this type of biometrics is smaller and an individual has an option of several fingers.

 

  • What is 1:1 (one-to-one) and 1:N (one-to-many) verification?

This may not be a FAQ on Biometrics attendance system but is an important one.

1:1 is a verification with pin where users require to key-in their pin before placing their fingers on the device. Then the device compares the call up template with the live finger for verification.

1:N is a direct verification of fingerprint which means the device will check for identification of the finger within its stored data for verification.

 

  • Why isn’t DNA widely used as a verification even if it is considered as the most unique form of biometrics?

A smart FAQ on Biometrics attendance system.

It is correct that DNA is the most accurate form of biometrics. But DNA is the most easily accessible form of a person’s identity, hence, it remains as an unsafe form of security verification.

 

  • Can a detached finger be used in Fingerprint scanner?

Fingerprint scanner only identifies live finger as the sensor can detect the moisture and the temperature of the finger.

Hence, only a live finger can be used for Fingertec verification.

 

  • Which is the recommended finger to be used for a fingerprint scanner?

This is another FAQ on Biometrics attendance system.

You can use any of the ten fingers for verification.

However, it is much easier for the scanner to capture the minutiae from index and thumb rather than other fingers.

 

  • Why are some 1:N users limited to certain number of users?

1:N users template is not call-up prior for comparison with the live finger. As the live finger will be compared with all the existing templates in the database till the matching template is found.

Therefore, in case the number of template increases, the searching time increases hence increasing the time of verification. Hence, to avoid this from happening 1:N users are limited to certain number of users.

 

  • What is the fingerprint verification system does not recognize my finger at all?

That is not a problem as there will other ways to verify the identity. Usually a fingerprint system have alternative ID verification that will help you log in.

 

  • What happens to the verification system in case of a power failure?

Usually fingerprint verification systems are powered with backup and battery. However, backup can last only for few hours, hence, safety measures must be taken to make sure that it keeps running smoothly or find other means to ensure safety for the premises.

 

  • Can fingerprint technology integrate with other security systems?

Fingerprint security systems can be integrated with other security systems. It can also be used as the main security system along with other security systems.

 

  • Can I adjust the level of security in fingerprint technology?

This is a significant FAQ on Biometrics attendance system as not many are aware that it’s possible.

Yes you can adjust the level of security in fingerprint technology according to your preference. There can be multi verification needs or lesser levels of verification.

 

  • If fingerprint identification expensive compared to other security systems?

It is not always more expensive than other security system. It can be if you are looking at two different type of qualities in different security systems.

But if you want to compare the same quality or same dealer’s security systems it costs just as any other decent high tech security system.

 

These are some of the FAQ on Biometrics attendance system.

A high resolution camera in case of a higher definition required for a larger space. Choosing a sensitive camera is good for catching images in a poorly lit areas.

 

  • What’s the difference between hardware compression and software compression?

Hardware compression consists of both capturing the video and compressing the video signal using DSP chipset integrated on DVR board. It is a low rate CPU and RAM resources In this system the computer CPU task focuses on the streaming of the video and audio to the network and saves the recorded data in the hardware.

While software compression is a DVD board that only captures video signal without compressing it.It is the high rate of CPU and RAM resources.In this case the CPU and RAM are usually overloaded. It is much easier to crash than a hardware compression.

 

  • Why do I get clear picture only during the day time and it’s blur during the night?

A FAQ on CCTV camera systems that seems to be every first time user’s problem.

It is a simple answer, it happens due to the change in depth of field and can be easily changed using the set of rules provided in the manual book.

 

  • How do I set up a camera and lens to use in a low light conditions or set up a camera with infrared lighting?

Placing a (ND1) Neutral Density filter in front of the lens can help the colour camera for low lighting conditions. While for a Mono camera you can use (ND3) Neutral Density filter in front of it’s lens for low lighting conditions.

For Mono camera fitted with I/R lighting place an (IRP) Infrared Pass filter in front of the lens should fix the problem.

 

  • When can I use a manual Iris lens?

The original rule is to use the manual iris or an MI lens only in an internal application. It is because while using MI one is dependent on an electronic circuitry  of the camera that is compensating for the light changes in the focus area. As this camera is not able to compensate for the scene as much as a auto Iris lens, hence it is limited to internal use.

 

  • How to back focus a camera that is fitted with a fixed focal length lens?

These are the five simple steps for this problem:

  •  Set the physical focus of the camera to infinity which must be done clockwise from the front row.
  • Aim the camera to the subject to be viewed
  • Release the camera back focus mechanism
  • Adjust the back focus to get the highest resolution possible
  • Secure the camera back focus mechanism

 

  • How to fit an Auto Iris lens to a camera?

This FAQ on CCTV security systems that has the simplest answer. Refer to the manual book and if not then a simple plug in connection to rear or on the side of the camera should fix this issue.

 

  • How to back focus a camera fitted with a zoom lens?

Follow these simple steps below:

  • Set the lens to full wide angle view
  • Set the physical focus of the lens to infinity clockwise as viewed from the front
  • Aim the camera to an object that is at least 30 meters away
  • Release the camera back focus mechanism
  • Adjust  the focus to obtain maximum clarity possible
  • Zoom the lens to full telephoto and focus on a nearby object
  • Keep the object in focus while zooming out slowly and if it is set correctly the it will remain in focus
  • Secure the camera back focus mechanism

 

  • What is the size of the monitor that should be used?

This entirely depends on the usage. For example: the number of images to be displayed in a given amount of time, the viewing distance and the available space.

 

  • What do you mean by video termination?

Video termination means the end line resistance of  CCTV camera. It must be set to 75 ohm. There is no requirement for setting every piece to 75 ohm only the last camera must be set to this ohm.

 

  • Is it mandatory to use a regulated power supply?

Yes, this will be answered with more clarification by the manufacturer as ro what type of power supply their system will require. However, in general yes it is mandatory.

 

  • What is the correct level for a video picture?

The correct level for a video picture is  1 volt peak to peak. Although this can only be set by an oscilloscope or a video level meter.
