The CCTV History starts when Siemens AG made it first test in Peenemünde, Germany in 1942.
The reason was to observe the V-2 rockets (the world's first long-range guided ballistic missile). developed during the Second World War in Germany as a "vengeance weapon", designed to attack Allied cities as retaliation for the Allied bombings against German cities.
The technological design of this first CCTV system was in the hands of the notable engineer Walter Bruch who did also the installation.
Seven years later the first CCTV system came to the market in USA, called Vericon.
The earliest video surveillance systems involved constant monitoring because there was no way to record and store information. The development of reel-to-reel media enabled the recording of surveillance footage. These systems required magnetic tapes to be changed manually, which was a time consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take-up reel. Due to these shortcomings, video surveillance was not widespread. VCR technology became available in the 1970s, making it easier to record and erase information, and use of video surveillance became more common.
During the 1990s, digital multiplexing was developed, allowing several cameras to record at once, as well as time lapse and motion-only recording. This increased savings of time and money and the led to an increase in the use of CCTV.
Recently CCTV technology has been enhanced with a shift toward internet-based products and systems, and other technological developments.
Close Future for CCTV Camera
In last years the cctv technology started changing faster than before. For example, before when the cameras were analogical with a low resolution, less than 400 tvl the most important for the market was how to increase the resolution since control station, business and houses needed to get a better definition on the image capture of its security cameras.
Everything changed, today we got a faster internet, and high resolutions in different cctv technology solutions, then the needs vary.
Clients use to buy the cameras TVI with AHD, bringing a great image definition very close to SDI camera.
The SDI was the first High Definition security Camera in the market, and still provide the higher image capture resolution in the market. The only problem the clients find in this product is the price compared to newer technologies like TVI, CVI, AHD.
IP is getting better day by day, with cameras giving more than 5 mega pixels, but with some relay because of internet speed and connections. But the internet is getting faster day by day, now we find internet over 50 mb/s. So we think in the future the DVR will disappear as the cable too. Because one day the cable will be substituted by wireless.
Now the cameras comes with night vision, colors, wireless, and so many other details that makes a client take a decision in one or other direction.
