When Doktor Jon started this little project, a conscious decision was made to choose the 'right moment' to introduce a specific section, detailing the use and benefits of Digital / IP CCTV systems. This decision was not taken lightly, particularly as there is so much which is misunderstood about conventional 'analogue' CCTV, and indeed so much deliberate misinformation put out about the brave new world of digital. At this time (June 2005), this section has been introduced to give basic background information on the subject, without intending to get too deeply involved in all the engineering implications for applying this technology. What should be a straightforward upgrade from proven to 'state of the art' equipment, can in practice be something of a minefield even for the most confident and knowledgable IT expert. We are repeatedly informed as an industry that "convergence" (the dreaded 'c' word) is almost upon us, with phrases such as "seamless integration" widely used by manufacturers to signify that you can easily mix and match their digital products with analogue equipment, and with hardly a care in the world. As you might imagine, the truth can often be somewhat at odds with what some experts may have you believe. Pure 'Digital' technology can indeed offer enormous operational advantages in many key applications, but there are still important technical considerations, which an individual should only ever overlook at their peril. In private, many manufacturers will readily admit to Doktor Jon, that "digital is not quite there yet", and much of the technology which has been borrowed wholesale from the IT industry, is readily seen as a way of squeezing out that extra little bit of profit, which is so often lacking from established analogue products, already price depressed through extensive free market competition. Now before we rush headlong into the 'brave new world' of digital CCTV, it might be worth considering first off, exactly what we mean by the term ....'Digital' | ||||||||||||||||||||||||||||||
