The first-ever mechanical CCTV Camera was developed in Russia way back in 1927. The development was originally made for Soviet of Labor & Defense consisting of a manually operated scanning transmitting camera paired with wireless short wave transmitter and receiver with a resolution of mere hundred lines. Yet another CCTV camera system was incorporated by Siemens AG at the test stand for Nazi Germany in 1942 in order to observe the launch of V2 rockets. The technology finally reached America in 1949 when a closed-circuit camera system by the name Vericon was introduced for commercial purposes.
The earlier CCTV System involved constant surveillance as recording hadn’t been invented yet. It was only in the 1970s when VCR technology was introduced that it became easy to record and erase info while video surveillance became more common. Moving to current times, we have seen a big leap in terms of advancement and now the internet based systems are quite common.
Coming to types of CCTVs currently present in the market, the most common ones are:
1. Dome CCTV Cameras
2. Bullet CCTV Cameras
3. C-mount CCTV Cameras
4. PTZ Pan Tilt & Zoom Camera
5. Day/Night CCTV Cameras
