HDcctv means no latency

If you have ever tried to follow a subject using a dome camera that is effected by latency then you will realize that in effect the latency issue renders the tracking feature useless. Up until recently IP had been the only way produce HD images so what happened if you wanted an HD  PTZ dome? Well the HD aspect was quite brilliant but the latency meant that guards tended to not use the manual control feature as the latency mean tracking became difficult if not impossible.

Then came HD SDI dome cameras. HD SDI is not effected by latency and the dome responds perfectly to the operator’s needs and as a result we are able to now offer a solution.

This is also true when reviewing recorded images over a network. IP has many benefits but again where there is latency there are problems. The solution of course is to up the bandwidth and reduce the frame rate and picture quality but does this then not defeat the the object of HD ?

Still as time goes by the latency issues of IP HD are being addressed. We soon expect that as networks become more efficient and sophisticated latency will start to reduce perhaps one day it will be un-noticable.

However until then HD SDI offers the solution to the latency issue and gives HD images to boot. Not bad for a technology that until three years ago was more or less unheard of.

Of course other advantages of HD SDI are more obvious , easy to install and understand, effectively its plug and play. In a world where installers are being squeezed from every angle a job that goes in well is likely to be a profitable job and that can make a huge difference to installing companies survival.

Clarius white light upgrades

It may be the height of summer right now and we are enjoying some fantastic weather all over the UK. Although it may not occur to many but now is the time to be thinking of upgrading your lighting to Clarius white light illuminators. Your lighting is crucial to protect you and support your HD cameras when those dark evenings start to draw in. Now is the time of year when traditionally many schools, colleges, factories, and office blocks carry out annual maintenance, mainly because the weather is at its best and many of the staff are out the way taking a well-deserved break. This gives the maintenance teams the opportunity to hire in  Cherry pickers to paint soffits and clear drains among other things… but what a great time to change your light fittings to Clarius white light illuminators.

These clever LED lights are designed to give you maximum efficiency and minimum maintenance. They won’t fail when you most need them and will continue to shine brightly throughout the winter months for years to come. Perhaps most importantly they will save you money in the long term.

Clarius white light illuminators

Reduced electricity bills as well as reliability  reduce costs  as well as offering better lighting levels and the ability to target the light where it is needed. This also helps to reduce light pollution so all in all Clarius white light illuminators offer an all-round package . So as they say , while the sun shines………………..

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.

HDcctv is it finding its way into industry as analogue fades away

Is the future HDcctv ?

As time passes the demand for high def CCTV images increases at an expodential rate. Conventional opinion says that HD can only be achieved by using  IP cameras with Megapixel technology. As a result over protective IT managers within some companies believe that there technical constraints that prevent them adopting the use of HD cameras and recording.

In the past this has held back the growth of HD as a technology however an alternative technology where High Definition CCTV cameras are able to digitally transmit uncompressed HDTV video signals through conventional coaxial cable has meant that people are once again touting HDcctv. This means that HDcctv can be used to upgrading many existing CCTV installations to HD because there is existing coax already in place. This potentially represents a very cost effective means to provide high resolution images.

As a result there are now many manufacturers exploring the possibilties that HD SDi represents.

Highest-quality signals

HDcctv signals over coax has captured the imagination of the industry and has resulted as a force to be reckoned with so much so debate rages on twitter and linkin as to whats better HD SDi or HD IP of course in reality each technology has its place and both will be able to successfully compete along side each other and time moves forward and HD becomes the minimum requirement for a CCTV system.

 

“HDcctv is the best thing that ever happened for megapixel IP surveillance. So says Todd Rockoff of the HDcctv Alliance. The transition to IP surveillance is well under way, as a growing number of security customers manage video from PCs, tablets, and smart phones.

Rockoff goes on to raise questions regarding the quality of both live view and playback video transmitted from Megapixel IP cameras, which can be limited by the bandwidth of the local-site IP LAN.

The rationale for HDcctv is straightforward. The quality of stored video is fundamentally limited by the bandwidth between image sensor and image storage.

If the bandwidth available, is less than required to transmit the native video format, then some compromise is required either a reduced frame rate, reduced resolution, and/or reduced frame quality through the application of video compression techniques.

More bandwidth between sensor and disk means higher-quality video, all else being equal.

A local-site IP LAN hosting 16 MP IP cameras offers at most 1Gb/s total bandwidth, and much more commonly only 100Mb/s, to be shared among all 16 cameras and possibly other IT equipment.

By contrast, 16 HDcctv-compliant cameras deliver 100% digital video at an aggregate bandwidth of 24Gb/s.

In order to keep file sizes manageable, not every DVR stores unadulterated video from all channels at all times.

However, the DVR is capable of storing vastly higher-quality images when it matters, for example per schedule or on alarm.

HDcctv has been introduced in the US where is has been very well received – it is now becoming available in the UK and looks like being equally popular.”
