FAQ

CCTV

What is the difference between IP and Analogue Cameras?

  • IP stands for Internet Protocol, and basically refers to a digital video camera that can send and receive data via a computer network, as opposed to sending a feed to a Digital Video Recorder (DVR). This is advantageous for a lot of reasons:Picture Quality,Video Analytics, Flexibility and Scalability

What is a DVR AND NVR?

  • DVR stands for Digital Video Recorder. A Security DVR is capable of taking the video from digital or analog cameras and recording it into a digital format on a hard drive. It can record high quality video, maintenance free, for weeks or even months. An ideal replacement for time lapse VCRs.

How many hours of video can the Security DVR store?

  • The length of archive depends on number of cameras, frames per second (FPS) and amount of available hard disk space. Our preconfigured systems usually provide several weeks of archive on motion detect mode.

How does motion detection work? Through the camera or software?

  • Motion detection works through the software in the DVR system by recording video when pixels in the image change. Most Security DVRs offer a sensitivity scale so the user can set the sensitivity of the motion detection.

Can I view live and recorded video locally?

  • Yes.

Can I view live and recorded video remotely?

  • Yes, most of our Security DVR systems are Internet enabled. You can view live and recorded video from anywhere through the Internet.

Can several users view one site at once?

  • Most Internet-enabled Security DVR systems allow multiple users to view the same site simultaneously. However, as more people look at the same cameras/DVR at the same time, the bandwidth will be shared between them.

Can I record audio?

  • Yes, if the Security DVR system comes with an audio option you can record audio. Most analog cameras do not come with built in audio, so you will probably need a separate audio kit.

What is an Auto-Iris Lens?

  • An auto iris lens provides consistent video signal in areas where light levels vary.

What is Lux?

  • Illumniation is measured in units called Lux. For more information, please refer to our LUX Explanation Page.

Can I zoom in with a camera?

  • Yes,

What happens if there is power outage?

  • Most Security DVRs will come back on as soon as power is restored. However, we suggest an uninterruptable power supply (UPS) which provides a short period of backup power and also serves as a surge protection device.

BIOMETRIC DEVICES

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

  • 1:1 is verification with PIN where users need to key-in their PIN before placing their finger on the device. The device compares the call-up template with the live finger to verify. 1:N is identification without PIN which means that the device will search among the database to find the template which suits the live finger being presented.

Can it be centrally managed?

  • Yes. Provided that the software has a central database where many clients can acess the database using their client software.

What data base does the software support?

  • MySQL, SQL and ORACLE

What is Biometric?

  • Biometric is the term used to describe the identification of persons based on their physical characteristics.

What are the different kinds of biometrics?

  • Common methods of biometrics systems include: Hand geometry, Fingerprint, Voice,
    Face geometry, Iris (eye) scanning. Each type has its advantages and disadvantages aking it suitable for different types of applications. In our time recording system, we use fingprint scanning.

Are there any health hazards related to biometric systems?

  • No. Biometric systems have been in use for many years and since it’s creation there were no reported health issues.

Can someone copy my fingerprint and implicate me in a fraud?

  • No. The device takes points on the finger and runs an algorithm or a very long mathematical calculation to arrive at an answer. This answer is cross checked against the answers stored in the enrollment process. The closest match is the correct user. NO ACTUAL PRINT IS TAKEN.

How does the Fingerprint biometric system work?

  • When an employee is first enrolled in a fingerprint-based biometric time and attendance system, the software records a template of the employee’s fingerprint and associates that template with theemployee. This template measures the relationship between various points in the fingerprint.Each time the employee attempts to clock in or out, the time and attendance device verifies that the newly scanned fingerprint matches the template originally stored for that employee.

What if an employee is having problems signing in and out?

  • Register more than one fingers for that employee. Suprema has the ability to record more than one fingerprint templates.

What is card access all about?

  • A Card Access system is a way of controlling and monitoring access to particular areas using cards. Card access, when properly installed and configured, is much like a traditional lock and key system, except that the key is electronic and programmable, and the use of the key is monitored and logged.

What happens if a card gets lost or stolen?

  • Simple. The administrator simply disables the card in the access software. The card cannot
    be used to gain access into the building again, unless reprogrammed for further use by the system administrator. This is one of the reasons why the use of biometric solutions for access control is recommended.

What if the power fails? Are the users locked out of their building?

  • When power failure occurs, users can use their mechanical key to unlock the door.

METAL DETECTORS

How much metal can a walk-through metal detector find?

  • Many walk-through metal detectors can be set to very sensitive settings, able to pickup
    something as small as a couple of coins in a pocket or a belt buckle. Most operators will
    adjust the M-Scope not to pick up small amounts of metal so as to allow more people to quickly walk through each hour. The M-Scope will detect guns, even at settings below 5% of its capability. Turn it up higher and you will start to pick up most knives as well.

What type of metal does the Fisher M-Scope and hand – held detectors find?

  • They can detect all types of metal, ferrous (with iron) and nonferrous. Some are more
    detectable than others. We encourage the operator to test and calibrate the M-Scope
    for their particular application.

What finds metal more effectively, a hand held unit or a walk-through?

  • Both can be equally effective provided they are used correctly. The primary benefit
    of a walk-though is that it is tremendous time-saver. So many more people can be detected in an hour, using a walk-through.

ID-CARD PRINTERS

Do you provide spare parts and consumables for the printers?

  • Yes. As the sole distributers of the Evolis printers, we provide all the spare parts and consumables of the products we provide.

Can the purchaser print on both sides of the card?

  • Yes.

Can I print on Smart contactless cards, or encode on magnetic stripe?

  • Yes.
