HD SDI cameras for the future

Much has been said about HD SDI and how it is going to compete with IP HD CCTV solutions. This is a bit  of a red herring really as the two technologies really are not competing for the same market place at all. IP tends to be installed in new buildings and larger installations where there is a requirement to expand in the future. HD SDI CCTV is much more suited to upgrade smaller analogue systems where there are no plans for expansion but picture quality is an important factor.

Each situation needs to be judged on its merits and things of course may change in time as each technology develops further especially if  HDcctv is able to work at some point over CAT5. HD SDI cameras are now slowly beginning to reduce in price as well. This has opened many doors over the last year as HD slowly but surely is becoming the choice of end users keen to try to improve their CCTV. systems.

What is the best way to decide which route to take for your upgrade? There are many choices out there. We have mentioned above how every site is different and each company will have their own specific requirements. Start with a simple question.

Is the site a single building and unlikely to change or is the system going to be deployed in several sites across multiple locations?

If the answer is just one site then look to HD SDI also see if you can use any existing coax on site. If you wish to view the CCTV from anywhere and across several different sites you must consider designing the CCTV system with IP as your first consideration.

If we have have a site that has good existing analogue cameras in place the route to explore could well be a Hybrid HD SDI DVR.  This means we can put HD SDI cameras on existing coax and leave any existing analogue cameras that we wish to maintain in place. Our other alternative is to put  IP encoders in place that will convert existing analogue cameras to IP. Fit some VMS software and then add HD IP cameras in any new positions.

There are many different ways to achieve the same goal. ie an HD upgrade. It takes lots of consideration and plenty of questions to the end user to decide exactly the best way to go.

 

Qvis HD SDI DVR

The new Qvis HD SDI DVR and camera range will be on sale and available to buy here in the UK from May 2012. 

The Qvis HD SDI DVR will have lots of juicy features as standard and these will include,

D1 imaging with 25fps recording on all channels.

H.264 compression this will enable the HD SDI DVR to reduce noise interference and in addition will include a de-interlacing feature.

The Qvis HD SDI DVR has intelligent recording technology, this is used to maximise the amount of data that can be held on the hard drive at any one time. With HD SDI the quality of the picture is second to none but the amount storage has to be well managed. Qvis have achieved this here with the Apollo unit.

QVIS HD SDI DVR

To give even further flexibility the parameters on each camera can be individually configured. This enhances the use of the audio features and as a result the Qvis HD SDI DVR has lip-sync audio on all channels.

Advanced search facilities allows  motion to be detected across an entire field of view or sub- regions of this with multi channel playback and single step searching meaning all events are easy to find.

The Qvis HD SDI DVR also has all the usual remote access facilities you would expect. Access cam be achieved both from your PC or your mobile device.

This HD SDI DVR gets its powerful performance from a dual-core CPU and can support 8 SATA HDD’s up to 24 TB it also has a built in web-server.

We expect the Qvis HD SDI DVR to retail around the £1300 mark so it will be highly competitive. Qvis also offer  HD SDI cameras within their new range. These include:

The 2MP Qvis HD SDI vandal proof dome.

The 2.1 MP Qvis HD SDI P400 C/W 100 IR leds giving a range of 100M of IR lighting at night.

The 2.1MP Qvis CMOS HD SDI speed dome .

The 3.27 MP Qvis HD SDI mini PTZ

So a small but exciting range of HD SDI products from Qvis available from May this year.

Grundig HD-SDI CCTV range

Grundig HD-SDI CCTV range.


Grundig has become the latest big name to embrace HD-SDI technology. They have released their new range of HD-SDI cameras, HD-SDI domes and HD-SDI DVR’s.
Grundig the German electronics manufacturer are claiming that HD-SDI CCTV will prove a major break through in the security industry. Now we have been advocating this for sometime, however as each day passes more of the larger names in the security industry are showing their hand with new HD-SDI CCTV equipment being released into the marketplace.

HD SDI DVR from Grundig
Grundig have stated in their latest press release “HD-SDI CCTV is a major breakthrough in the security industry. It enables the transmission of uncompressed digital video at a higher quality than IP, yet uses the same simple installation method as analogue coaxial cable. It also does not require expert IT support”.
Grundig’s senior product manager, Andreas Kronwald, explains: “Grundig’s HD-SDI products operate at 1080p progressive scan, 1980 x 1080 pixel resolution and 50 / 60 fps. This compares to D1 resolution at 720 x 576 pixels and IP megapixel cameras at 1280 x 1024 pixels. The recorders support 120 fps and offer up to a massive 64 TB of storage. Unlike IP CCTV, HD-SDI uses no compression at all, so image quality is optimized. It even enables installers to offer a digital upgrade to analogue systems, re-using the existing coaxial cable infrastructure to save money”.

Well  we need to see what price Grundig can market their HD SDI CCTV product for , however the competition is hotting up and prices will fall as a result.
Grundig’s spokesman continued “HD-SDI is presented in 16:9, widescreen format, meaning no black bars appear on monitors. Transmission distances are currently 100m and similar to IP. However, developments in SDI-specific, fibre optic transmission systems are extending transmission distances to many kilometres”.
Grundig have made clear that an HD-SDI CCTV system can still be connected to an IP network enabling all the features you could expect from a standard DVR that was remotely monitored. Grundig’s approach is to emphasise to end users the ease of installation and they claim that. “HD-SDI a CCTV not IP, with limited external access. It is intrinsically safe, far simpler to protect, ideal for installers and very effective in security applications”.
This entrance into the Market place from Grundig comes hot on the heals of the Samsung SRD480D and its HD SDI camera the SCB-6000 all very encouraging for the advancement of HD SDI CCTV as a technology that could soon bring HD to the smaller CCTV installer and their customers.
