the digital disruption of cctv
DESCRIPTION
A shift from analogue to digital, IP-based CCTV is currently taking place. What will happen in the future?TRANSCRIPT
Our Big Brother has grown bigger and bigger over the last decades.
Video Surveillance has been a growing business, with high profits and a stable industry structure.
9/11 implied a further increase in surveillanceand people are increasingly concerned
about Big Brother nowadays.
Few people, however, express their concernabout the manufacturers of these cameras.
… And why should they?
… to digital cameras...
… which are connected over the internet.
Digital, IP-based CCTV offers manyadvantages over the old systems…
Less wires and cabling…
… Implies a lower installation cost…
… and cheaper maintenance.
In addition to this, once cameras are digital, surveillance can be made increasingly
intelligent by using software.
And maybe more importantly, the image quality is better nowadays if you choose a
digital surveillance system…
But why should this change make anyoneconcerned about the analogue camera
manufacturers...?
Well, shifts to digital technology have with no exceptions created a lot of industrial turbulence…
Old, analogue companies have been destroyed or severely wounded in industry after industry…
Let me give a few examples…
Kodak employed 140 000 people in 1988 - today less than 25 000. In ten years the stock has declined
from around 90 USD to 2-3 USD.
The shift rendered Kodak’s film business obsolete.
The manufacturers of mechanical calculatorscollapsed in the early 1970s when the shift to
electronics took place.
The typewriter companies collapsed…
Back in the 1950s and 60s, analogue radio companies were extinguished…
… Transistor radios had removed the market for the former technology.
About 1000 Swiss watch manufacturers died duringthe period 1970-85…
… when digital watches became cult products.
While NCR survived the shift to electroniccash registers, most established firms went
out of business.
Old TV manufacturers encountered a lotof problems…
… when TV screens became digital.
The same thing
happenedwith
telephones.
Do I even have to mention the music industry?
Interestingly, digital video surveillance has to a large extent been introduced and
developed by entrant firms…
… such as Axis, Mobotix, Indigo Vision etc.
Analogue companies like Pelco, Siemens, Bosch Security, GE Security have so far failed to dominate the new technology.
IP surveillance has grown rapidly over the last five years, however, only about 20 percent
of all sold cameras are digital today…
This figure suggests that the displacement of analogue cameras has just begun…
… and that some major industrial turbulencewill take place over the coming years.
This has been the case in all industries that have shifted to electronics.
Why would the video surveillance industry be an exception to this stunningly consistent pattern?
