Biometrics, the safest form of access control

How biometrics is the smart way to point to the future.

Anyone who has been responsible for administering an access control system of a reasonable size will know that their staff have a very annoying tendency to lose their prox cards on a fairly regular basis. This can be costly for starters. There may also be a high staff turnover so cards may need to be replaced frequently. Its for this reason and of one of security that anyone with this sort of scenario should be made aware of the potential benefits of biometric fingerprint readers.

Obviously it’s much harder to leave your fingerprints on the train, and its also less likely for fingerprints to be copied or stolen . However technology in the past has meant finger print readers can be slow and unreliable. Not anymore though.

iEvo Readers have been designed to deal with problems that affect fingerprint recognition, sun rain frost etc. They have and developed a system that reads beneath the fingerprint itself and its much more reliable. It is called multi-spectral imaging.

iEvo now has its reader installed on buildings such as construction sites, offices, schools and colleges and its multi-spectral imaging technology is gaining a good reputation in the industry.

iEvo have readers installed across the UK and also abroad in places such as the Middle East. Instead of using a pin-code or a card system, people are waking up to the potential of biometrics.

The iEvo system is derived from technology used to painlessly scan blood sugar levels without a needle.It is operational in a range of temperatures from -20C to 70C, and can be integrated into existing systems such as NET2 and is so clever it can get a reading through obstacles such as dust, dirt and water.

“It works by scanning the finger 4mm below the surface of the skin itself using nine different formats of polarised and non-polarised light.

This allows the reader to identify the unique network of patterns on the human hand, below the top layer which can be affected by dirt or wear”.

“While the system can identify up to 8,000 different patterns, it does not store any of the prints itself. Instead, it stores the certain features located around the print called minutia points, transfers them through an algorithm in an encrypted form and stores them as a binary code”.

iEvo extract a pattern from a print so you can’t merely re-engineer the fingerprint from any of the information stored on the system.”

iEvo products are also able to integrate into existing card and fob systems and they also are available in a range of custom colours to match with existing fixtures and fittings.

Samsung HD SDI DVR

We look at the Samsung HD SDI offering here at HD SDI DVR is it a product that Samsung have released to make up the numbers or are they really looking to take a grip of the HD SDI market place?

Samsung have started to advertise and promote their new product line that moves them into the new HD SDI CCTVmarket place. Previously Samsung have been advocating IP and the benefits that this can deliver in the form of HD. By actively promoting HD SDI technology  built into Samsung’s new HD-SDI cameras and DVR, we can see just how much this is now in the minds of all CCTV professionals.The Samsung HD SDI CCTV solution allows the transmission of uncompressed and non-packetized Full HD (1080P) video over analogue cabling and as a result suits deployment here in the UK because so much coax currently exists here.

The main benefits of HD-SDI technology is that there is zero loss of image data and zero latency when viewing images. Samsung have released two new HD SDI cameras into the market place. These are the SCB-6000 fixed camera and  SCD-6080 internal dome. HD as we know ideally suits many applications especially where HDcctv images are required. Many businesses including airports, ports, banks and casinos will gain a great deal more detail from usingHD. This is especially true in situations where it is not always simple or cost effective, to send HD images over an IP network.

So now Samsung has the cameras to produce HD images over coax they have also introduced a four-channel HD SDIDVR. The new SRD-480D DVR offers real-time 1080p across selected channels. When using the DVR on the 720P resolution, real time can be achieved across all channels. Both the new cameras and the Samsung  HD SDI DVR is fully compatible with Samsung’s licence-free Net-i Viewer software. This allows users to view analogue, IP and HD-SDI technologies on one common platform. Installers can now offer their customer base all the benefits of HD megapixel cameras without having to have any specialist knowledge of IP based systems.

The SCB-6000 fixed camera and SCD-6080 internal dome have included as standard Super Noise Reduction (SSNRIII) technology. In addition both are true day/night HD SDI cameras transmitting full HD images up to 100 meters over coax in real-time. With images recorded at 25 frames per second the end user experience is one of seamless movement and high quality HD. Both models are now delivering over five times the image resolution that standard definition analogue cameras are able to achieve.

The maximum transmission distance between the SCB-6000 or the SCD-6080 and the HD SDI DVR is 100 metres, however this can be increased to 200 metres when low-loss L-6CHD coaxial cable is installed. To increase transmission distances even further Samsung intend to  introduce the SPH-120R Repeater very shortly.

HD SDI DVR demonstation

HD SDI CCTV has many things going for it in this age where HD images are becoming very important to you the installer in order upgrade your existing client base. possible though the best thing is just how easily this can be demonstrated to the client. All you need is an HD SDI camera, a 4 way HD SDI recorder, a good 1080p capable monitor, a power supply and a tripod. Put this together and you have a fantastic tool to actually show the images images to an end user.

The power of the dem has been something that all salesmen are acutely aware of. If it goes well ,as a salesman you are halfway there. Once your client has seen what an HD SDI DVR can do for them in terms of quality upgrade they are going to find it hard to go back and look at their rather grainy , half baked analogue images. If you can show images size by side all the better as you can dem just how much more information a 1080p image can gain.

All in all though HD SDI CCTV is starting to compete in terms of cost with analogue. To be fair its not quite there yet but it will be within 2-3 years and with the amount of analogue CCTV that is out there in the field HD SDI may prove the best way to upgrade old worn out equipment and get the benefit of HD images into the bargain.

So if you are looking to sell HD SDI equipment get your dem kit here and start putting ideas into your customers heads

 

HD SDI CCTV the future of surveillance in the UK

HD SDI CCTV has become more than just the third way to upgrade to HDcctv images. In many cases it is now considered the only way. If you have a CCTV system that is currently analogue then you can upgrade to HD by re-using existing coax and adding HD SDI cameras and an HD SDI DVR. This is a far more efficient solution than running new cat 5 cable and then upgrading all your analogue cameras to IP.

The images you can view using HD SDI cameras are up to 6 times better than you will have been used to with your analogue CCTV system and customers are being impressed by the improvement they can make to their security systems as a result.There are many reasons that you may wish to chose an HD SDI DVR  over a VMS platform . The overriding reasons though are simplicity and price. With more and more manufacturers latching on to the benefits of HD SDI CCTV the choice of products now being produced is now one that is being exploited by installers.

HD SDI CCTV is ideally suited to 4 ,8 and 16 way installations this is because the maximum cable run without HD SDI extenders is 90 meters. To be fair this is no different to the distance an IP camera can be specified from a switch but the benefit of HD SDI hardware is that is simply plug and play and this is being exploited by CCTV installers especially in the UK. With the ability of remote connection via iPhone and iPads and other smart devices end users can monitor their premises 24 hours a day if they wish. The overriding benefit though is pure HD images. This is the future of CCTV systems and HD SDI DVR’s and cameras is making this transition very easy indeed

HD SDI DVR price drop. Will it continue?

HD SDI DVR’s are they getting cheaper?

HD SDI DVR’s are dropping in price as more and more options start to flood into the UK. Following the success of HD SDI CCTV in general at IFSEC this year  it seems installers have been selling the concept with a great deal of enthusiasm. It also seems that HDcctv compliant recorders are the preferred way forward. It is widely accepted that those badged as compliant are viewed as more reliable and more trustworthy. This of course does not mean that those HD SDI DVR’s that are non-compliant are not still a good option as long as the supplier is able to provide cameras with the product and guarantee they will work seamlessly together.

Everfocus HD SDI DVR was the market leader.

It remains to be seen who will come out on top as market leader but Everfocus certainly had a big head start. Analogue sales are still in the majority here in the UK but the signs are that the trend towards HD will continue to drive CCTV sales across the globe but particularly here in the UK where we have a huge legacy of coax infrastructure. Many end users are reluctant to replace all their cameras. As a result many have expressed an interest in targeting areas for HD SDI cameras rather than upgrade their entire system . With this in mind the Hybrid HD SDI DVR has been a popular choice for many. Combining HD SDI inputs with analogue inputs it allows this targeted response to HD and in times of austerity like we are currently experiencing it makes a lot of sense for many businesses.

HD SDI DVR verses Analogue CCTV

Just how good though is HD SDI compared to analogue? Well at 1.5 to 2 megapixels being the general standard HD SDI camera output the definition is at least double what was achievable previously. To the human eye though an HD upgrade looks remarkably impressive and this is matched when reviewing recorded images. The ability to zoom in on an incident without the image becoming blocky and blurred is the major benefit of HD SDI CCTV. Add to this the fact that there is no latency between the delivery of the images and many are questioning whether this technology is better than HD IP. The arguments are many on that subject but for a simple installation, using your existing infrastructure, HD SDI CCTV is the ideal way forward.

Will the prices drop further?

Further price drops are inevitable. The aim of Everfocus and other big names who now manufacture HD SDI CCTV equipment have always aimed to compete price wise with the top of the range analogue kit. This seems achievable now as new chip technology helps reduce the prices even lower and even faster. It is possible we could see some parallel pricing with analogue within two years. In the meantime its important to realize price is not everything . Quality must always come first and this is improving by the day as HD SDI technology just gets better and better.
