CCTV software.

Over the next few years we will begin to see hardware recording solutions in the CCTV security industry slowly disappear and be replaced almost exclusively by CCTV software.

Cost of CCTV hardware.

The high production costs of hardware have in the past always been able to be offset because most end users networks struggled to cope with the high amount of bandwidth taken by HD and Megapixel IP cameras. Recently however, there is a marked change. Recording solutions are beginning to be biased towards CCTV software platforms recording onto dedicated servers. The servers are getting cheaper and developers have taken all the best features from their hardware recorders and integrated this into CCTV software solutions.

CCTV software.

The software of course can vary enormously. Some manufacturers such as Sanyo are happy to give away software in order to sell their IP cameras in volume. Other big players such as March networks have spent lots of time money and effort on developing their Videosphere VMS software into a fantastic package that includes analytics and extremely advanced search facilities not seen in cheap or free CCTV software packages.

Who decides.

Of course the decision will always come down to end user and their requirements. Anyone trying to integrate CCTV systems that already exist on site will not be able to use off the shelf packages. They will have to choose a CCTV software solution that can integrate a multitude of cameras and codec’s especially when using a combination of analogue and IP cameras of different makes and model. The older analogue cameras will need some kind of multiple recording platform and then conversion to IP video streams.

The future.

CCTV software can and will get better and better. Software gives flexibility that older hardware DVRs lack. It will eventually get less expensive and remote support for the product is easier than returning a DVR back to its country of origin just simply to be repaired. The benefits and advantages of using CCTV are slowly but surely meaning that DVRs are soon to go the same way as the VCR.. Ie it become a very breed indeed.

Megapixel over coax.

EverFocus have released the new EQH5200 2 megapixel IP camera that is using the latest HD-SDI serial digital interface to open the retro fit market place to megapixel technology. The EQH5200 megapixel camera is able to send images down existing RG 59 coaxial cable from a BNC connection therefore meaning easy retrofit installations for installers and therefore a more competitive upgrade solution to analogue CCTV cameras.

The camera has compact box design complete with day/night  functionality and an on screen menu set up to assist CCTV engineers.

Everfocus DVR

To compliment the ease of retro install EverFocus also have the EHDR08 8 channel DVR this unit can reproduce recordings boasting resolutions of 720p and comes in the form of a compact box design It uses the latest H.264 compression techniques and handle up to 8TB of hard drive recording space.The DVR can also output to a monitor using either VGA or HDMI.

Remote connectivity.

For those interested in remote connectivity  the EHDR08 has a 1 gigabit Ethernet interface this allows networking capability and allows remote viewing and management of the CCTV system allowing smart search functionality. Monitoring from mobile devices that is now really catching on can be achieved through 3GPP connection. A DVD burner allows information to be easily removed when required.

What we have all been waiting for.

In essence the package provide a simple megapixel solution over coax something that many installers have been waiting for for some time.

Many years ago, the options for CCTV recording were limited

Time lapse VCR, coupled with a Video Multiplexer, meant in essence 1 picture per second per camera maximum…..you couldn’t have different settings for different cameras, it was a global setting……everything backed up to your commonly available VHS tape.

The VCR manufacturers recommended replacing the VHS tapes every 10 uses – but more often than not, calls to a site to fix faulty VCRs led engineers to observe 31 VHS tapes that probably had never been changed since the installation was completed.

But, 31 tapes was convenient……rows of shelves with ‘week 1 Monday’ etc marked neatly on the spine of vertically positioned VHS tapes…..keen operators would add the daily cycle of removing yesterdays tape and replacing with today’s to their early morning to-do list……along with the panic if they were going to be late and the tape would run out leaving the system non-functional until the tape swap – ‘Mike, I’m late, swap the tape in the Video Recorder before Stan finds out’!!!!

Along came clever manufacturers such as Dedicated Micros and Tecton, who introduced amazing digital recorders that meant the daily routine was no longer required…….PC Hard Drives replaced the fragile VHS tapes……high quality images replaced the fuzzy images on used Tapes…..31 days recording at 1 picture per second per camera was now possible in glorious digital !!

Things have changed enormously since those first DVR days…..

DVRs now can have individual settings per camera, meaning important cameras, I.e. Cash office in retail, can benefit from more pictures per second….. Settings can also be time scheduled, allowing cameras to record continuously in one time zone and then motion only record out of hours – thus stretching record durations even further….

Add in the ability to set different qualities of picture resolution and the systems of today are truly flexible by comparison

But why are we still an industry hell bent on 31 days recording ?? Are we really stuck in the 31 day tape shelf mentality?

Too many tenders are released that stipulate ‘minimum 31 days recording’

But ask yourself this, back in the day, when were you asked to review ‘Week 2 Tuesday’ tape for vandalism to the front door?? Because, 9 times out of 10′ it wouldn’t be ignored for 31 days that the front door had been vandalised – more likely the next day at the most before Janice in Accounts let’s you know she couldn’t get in!!

Don’t get me wrong, there are applications that simply must have long term archives – banking and retail have policies that require transactions are accessible for long periods after they occur…..but in the main, most CCTV installations are designed to offer visual verification for ‘now’ or ‘nearly now’ incidents…..

With Hard Drives getting cheaper, the only real problem facing DVR manufacturers is the physical size available to hold HDDs inside…..most DVRs allowing 4 or 6Tb of internal storage without the need for external additional storage……

But, cameras are getting higher resolution…..megapixel IP Cameras, PIXCs, HD cameras, call them what you want but higher file sizes are what they offer……

Surely it would be better to record at the highest resolution and fastest picture update than to record for durations that simply aren’t needed? Reduce the duration to a week, maybe 2 if there are holidays, and see the recorded footage in the quality the manufacturers want you to see it in.

Don’t worry, the door will still get vandalised, Janice from Accounts will still let you know, but now it will be in glorious, high resolution, near real time quality!!

Let us know what you think – but get off the 31 day train !!!

Decisions , decisions

If you are the  MD of a company who is about to upgrade or install a new CCTV surveillance system, you are probably going to be faced with some pretty tricky decisions on how you are going to approach the subject. The three main questions you will need to ask yourself are:

1)      Will I just upgrade my analogue cameras for new analogue cameras?

2)      Will I use a mixture of my existing equipment with new IP camera technology .i.e. a hybrid CCTV system?

3)      Will I go for the latest IP Megapixel camera solutions with a VMS recording platform?

CCTV solution? Too many choices?

The problem is there is no clear answer on this. Option 1 will almost certainly work out the cheapest at the point of installation and the results you will be able to achieve will mirror those of any previous analogue system you have used. The cameras and DVR may well have more features but overall system performance is going to be the same.

Hybrid CCTV.

Option 2 will give you a half way house solution. Hybrid systems combine analogue and IP cameras with the potential to record on either a DVR or an NVR but you will have to convert the cameras to either analogue or IP at the point of recording. Having said that some companies advocate the use of a Hybrid DVR that can handle both, but long term support for these products is distinctly questionable. However for the time being they provide a convenient bridge between the two technologies.

IP CCTV.

Finally option 3. This will mean a commitment to the future, but one that is still evolving. With megapixel cameras you really need to consider your companies network capabilities to ensure the frame rate and picture quality are maximised. It is inevitable that IP products will be the dominant force in the CCTV market place over the next 5 years. Analogue solutions have reached their ultimate performance levels and have become as cheap as they ever will do. The price of analogue will rise in time, which is why option 1 may not be the cheapest route in the long run. Conversely IP products will fall in price sharply and the options and ranges of the camera and recording products will be wide ranging.

Buy IP CCTV solution.

So as an MD the decision is defiantly not easy, proper advice should be sort to ensure that a supplier with an installation preference does not force you down the wrong route. So thought and consideration is now crucial as to the decision……… “Buy IP Camera solution”? probably …yes!

Today, we take a look at Mesh Wireless Networks

Potential Benefits:
Video surveillance is often wanted in areas that are remote from buildings, such as in parking lots and along fencelines. Running network cabling can be cost prohibitive and requiring expensive and/or disruptive trenching.

Ip wireless systems offer a wire free alternative to transmit video in those areas. Mesh wireless systems (a specialized form of IP wireless) allow video to be transmitted across longer distances and around areas of interference (like hills or trees etc)

Costs: Compared to long distance cable runs, mesh wireless is generally significantly less expensive. Even at about £1500 per wireless node, wireless is far less expensive than almost any form of trenching across roads or pavement.

  • End User Risks:
    Because of the bandwidth demanded, deploying wireless systems for video surveillance require specialized expertise. If end users do not choose experienced installers, significant delays may occur. Additionally, risks exist in the long term performance of the system (as environmental or local changes can degrade performance). It is imperative that customers budget for long term maintenance of the system or major issues could occur.
  • Installer Risks:
    Deploying wireless video surveillance networks may be the single most difficult technical task in all of video surveillance (even harder than video analytics). Wireless demands technical expertise in both IP networks and wireless systems. Futhermore, wireless systems can be impacted by external factors such as the weather and nearby wireless users (because most systems are licence free). Two specific risks are : (1) systems that do not deliver as much bandwidth as the installer plans and requires and (2) ongoing stability problems with the system that demand expensive service calls.
