CCTV Technology offered by Halo Security

September 9, 2008 by · Leave a Comment 

CCTVThe more recent developments in CCTV or Closed-Circuit TV have transformed what we can expect from a CCTV solution.

 

Far from just replaying footage of an event using tapes and a basic time/date search one can now search a digital archive using ‘thumbnail’ views to find what one’s looking for quickly.

And that’s just for starters…

‘Intelligent’ motion & non-motion technology can provide alerts when someone or thing enters the image or when something is left behind i.e. a mystery bag at an airport which could contain a bomb. Systems can detect this and more automagically!

The days of having guards manning a site are over- the technology can do the monitoring and only call for assistance when required.

Darkness remains the biggest challenge for cameras but new Infra-Red technology, invisible to the naked eye, allows clear images in total darkness.

For even longer-range night viewing, Halo Security holds a U.S Government export license for 25 Hz FLIR Thermal Imaging Systems – which are a controlled military technology. It displays Infra-Red thermal energy and assembles it so that it may be viewed on a screen. As IR is sometimes only minimally distorted through fog or rain these cameras can work well in difficult conditions (see video) but their main drawback is that they cannot show facial detail.

There are literally thousands of permutations and possibilities with CCTV systems and budget is the biggest constraint. Having a clear budget allows a Halo Security Technology Specifier to deliver what the clients needs rather than wants so that quality is maintained. We have to maintain a focus on the end game, delivering court-admissable recorded footage. If the budget only allows for 5 good cameras, that’s far better than 10 bad ones!

 

  CCTV Fact 1:  Tapes are gone – they have been replaced with DVR’s (Digital Video Recorders)

Owners and managers of premises also need to know that if there is an altercation or personal injury on the premises that there is recorded evidence available to the police to assist prosecution and to prevent false claims.

   CCTV Fact 2:   Too often CCTV images are too poor to be used as evidence.

Halo Security’s aim is to provide 20:20 hindsight on all recorded images. That means when we walk through your premises and specify a solution our objective is to consider light, distance, camera type, camera position and other factors to correctly specify a solution that will provide usable recorded data – we are more interested in providing a solution – not only a means to reducing an insurance premium.

   CCTV Fact 3:  DVR’s are PC-Based or non PC-Based

PC-based DVR’s offer the best features and are, at their core, computers but are designed for continuous running. The quality of the hardware and software is critical but when done right they provide a versatile multi-function system that can not only catch criminals, but also improve business efficiency through motion and sensor based alerts. These systems are being used in the manufacturing industry to automate quality control.

Standalone DVRs are an ideal budget alternative. They are generally quite stable but are not always user friendly and take a bit of getting used to.

CCTV fact 4:   The ‘live CCTV image’ in a CCTV system is not the same as the recorded image. 

Quality is lost in the recording process. Maintaining Image Integrity is paramount to Halo Security’s ethos. The central aim of any CCTV system is to provide incontrovertible evidence of historical activity.
