Choosing Your Cctv

When you decide to get CCTV it will likely be because of the many different security

advantages it provides you with or because of the extra safety it provides for you and your staff. This is a great decision that will greatly affect your business in more ways than you might at first realise and is a great decision, but there is more to getting CCTV than simply deciding you want it.

Next you need to decide on specifically what type of CCTV you want for your premises and this will greatly affect the effectiveness of the installation. The decision here is mostly between analogue or digital CCTV and each type has its strengths and weaknesses. The eventual type you decide upon meanwhile will likely depend on both your personal preferences, and the exact requirements of your specific business and premises. Here we'll look at how each differs.

Analogue:

Analogue CCTV is essentially CCTV that utilises a VHS. This means that the footage is streamed onto the television and then recorded from there as it is using a conventional video recorder. This then means hat you can only have one channel recording at once (as is the case when you use a VHS normally). This means that you can only record from one camera at a time. For small premises this is fine as one camera situated well in the corner of the room will cover the whole area. However if you want to record many different angles and areas you will then be forced to programme a set pattern into your CCTV whereby the image flicks between different cameras. This could mean that you miss something vital if the video is on the wrong channel at the wrong time.

Another downside of analogue CCTV is that you will have to either destroy or store hundreds of VHS tapes which will take up a lot of space. Of course you will have limited

Digital:

Digital CCTV is essentially the equivalent of a digital camera set up around your office or building. This then has all the advantages that digital normally has over analogue, meaning better frame rate and definition as well as the ability to alter those settings to shrink the file size. You will be capable of having multiple tracks recording at once meaning that you can view various parts of your building simultaneously. At the same time you will be able to store the files digitally meaning that you can compress them, email them, stream them and more and meaning you don't need to worry about storage space. Down sides however include the fact that digital systems can sometimes crash or break down, and that they are more expensive. This makes digital CCTV the obvious option for big business and companies that are serious about their security, but for those who are intimated by technology and software that could go wrong, or who do not need to spend as much and have smaller premises, analogue may be more fitting.
