White light illuminator ,IR illuminator

White light illuminator, IR illuminator or even halogen lighting. Which ever form of lighting you chose to compliment your HD CCTV system it is crucial to consider your CCTV lighting plan with the same level of thought as you choose your HD SDI cameras and your recording solution.
An HD CCTV system without an White light illuminator is like a conductor without his orchestra. One needs the other.  Without lighting you will not see anything and colour is impossible to reproduce. HD CCTV is far more sensitive to light levels than analogue and installers need to let their customers know at point of sale. Don’t just hope ambient lighting will be sufficient. It wont!
In response to the obvious need for CCTV lighting many HD SDI camera manufacturers are including IR illuminator LED’s within their camera unit itself. Anything from 12-96 IR LED’s can be seen fitted to many HD SDI cameras now depending on the distance the installer is trying to achieve. These cameras work well and we would recommend them , however there is always a scenario where a White light illuminator will be needed, this is of course where colour images at night are important.
Here at HD CCTV solutions we stock one of the most robust range of white light and IR illuminators on the market. Manufactured in the UK, these tried and tested CCTV illuminators are ideal where an HD CCTV system is being deployed.
So think CCTV lighting when designing HD CCTV systems and think White light illuminator for colour IR illuminator for covert lighting , easy to install highly cost effective and efficient and a compliment to any CCTV system you are installing.

Benefits of HD CCTV over coax

Posted on by | Leave a reply

The benefits of HD CCTV over coax are many. The introduction of HD-SDI cameras and recorders has seen a change in the way many companies are now influencing their customers to buy HD CCTV. IP is no longer the only option and in many cases now no longer the prefered option . We list below some of the benefits of HD SDi CCTV and see why some installers think HD SDI could change the industry as a whole.

Higher resolution is the primary benefit that is gained from HD SDI CCTV. HD-SDI cameras output full HD resolution images (1080p) but unlike IP this is done in real time. This means that HD SDI cameras  can give the end user as much five times the resolution of standard analogue cameras. HD-SDI DVRs are also capable of recording full HD. This means up to (1080p) Full HD resolution images. The primary benefit of this is that the end user will get real-time recording. HD CCTV has now already filled one one of the fundamental requirements of a CCTV system. Quality images that the end user can rely on.

Of course one of the main drawbacks of analogue CCTV is the amount of data that is sub standard. HD-SDI is an HD CCTV solution that provides video signals that are not compressed before transmission. This means that unlike IP there are no distortions within the captured image or frame rate interruptions. Zero latency can be achieved  because HD-SDI transmits a digitized video signal meaning no reduction in quality of the images which often occurs with analogue.

Perhaps the best news for the CCTV industry with the introduction of HD-SDI DVR s and HD CCTV cameras is that they can use an analogue infrastructure. In other words HD CCTV over coax.This makes them suitable for users looking to increase the quality of their current security systems. Why re-cable when HD CCTV can be achieved with little effort and lower costs that installing a new IP CCTV system?
HD CCTV cameras and DVRs are similar to standard definition cameras and DVRs in the way they need to be installed and do not require any additional specialist knowledge or skill. Re-training that has added a heavy burden on the CCTV industry is no longer required. HD-SDI is not prone to issues associated with IP network based video surveillance systems. The installer is no longer dependent on third party IT companies to install or allow access to IT networks. One of the biggest benefits being seen is that no IT or IP network knowledge is required and bandwidth requirements are a problem of the past. We are back to a simple CCTV installation.

 

Avigilon financial figures q1 2012 shows HD CCTV growth is accelerating

Posted on by

Avigilon have released financial figures that prove the shift to HD CCTV is accelerating and at quite some rate! With revenue up 77% the results are encouraging for everyone who is trying to promote HD into the world of CCTV and Avigilon’s approach and easy upgrade path from analogue to HD is proving highly successful.

Who is looking beyond IP surveillance?

Posted on by

PSI magazine, a very well respected monthly security publication has recently ran an excellent article with the very clever headline “Know IP or no IP” . Essentially the article centred on how the security industry is embracing (or in many cases not embracing) IP technology in order to drive sales and move the industry forward to another level. Several commentators take a view on whether the CCTV industry as whole has the technical knowledge to advise, sell, install and service IP CCTV in a way that will bring improvements, reliability and satisfaction to the end user.

What all the commentators seem to agree on is that IP is inevitable, analogue CCTV as a technology is finished and it is now just a matter of time before those who have invested in IP surveillance training, ICT staff and IP CCTV products will prevail. In market that before IP CCTV came along, was dominated by installers who generally operate with 5 or 6 hard working staff and have little or no time to invest in a discipline that is far more demanding than installing simple closed circuit analogue systems, this news is quite daunting!

Now it has to be noted that IP CCTV brings many benefits but the most obvious is HD quality. This is the driving force for IP CCTV to really take off and this is what will cause forward thinking end users to upgrade. It was noted that  in a later article on P40 there is a quote that suggests” if you want a high resolution system you have to go IP”, ironic then that the advert directly following the “Know IP or no IP” article is for the new HD SDI CCTV range from Videcon.

Now that is forward thinking!!!  HD SDI CCTV offers high definition images over coax. It is widely acknowledged that coax makes up over 70% of all CCTV systems here in the UK at present. Many of those systems consist of less than 16 cameras and many of those systems need upgrading. Many of those systems are installed and maintained by CCTV installers who have little desire to go over to IP CCTV technology.

It would therefore be fair to ask then who is looking beyond IP surveillance? Is HD SDI CCTV a technology that can allow smaller traditional CCTV companies to compete against the tide of IP CCTV products flooding the market place? We certainly think it is!

HD SDI technology allows you to connect 1080P and 720P CCTV cameras using existing or new coax. This gives the benefit of HD resolution without the need to run these images over an IP network. The obvious advantage is that true broadcast quality HD can be viewed and recorded without the need to compress the images in order transmit across a TCP/IP solution. In addition no training or IT knowledge is required. This makes this technology a favorite with many existing CCTV installers especially in the UK where we have so many existing analogue CCTV systems that need upgrading and enhancing. HD CCTV is the ultimate answer to all our issues with poor picture quality from analogue cameras.
