It can be said that the presence of CCTV is something we take for granted these days. Whether we're walking down the street, out shopping, working out at the gym, out for drinks with friends – security cameras are omnipresent in our lives, even outside our own homes. It is something that we have come to accept and expect.
Their benefits are clear – with the means of monitoring and recording any incidents, businesses and consumers alike can make use of CCTV installers to boost security and to increase peace of mind.
Throughout the last 50 years, the abilities and overall qualities of CCTV systems have (unsurprisingly) developed. In this blog, we're going to take a look at how security camera technology has changed in that time,explaining why now is a great time to invest in such a system.
How The Work of CCTV Installers Has Evolved
Live monitoring security cameras.
The earliest use of CCTV technology was in Germany, during the Second World War. In 1942, engineer, Walter Bruch, set up a camera system that was designed to monitor the development/performance of V2 rockets.
It wouldn't be until 1949 that similar technology was used commercially, through the US government contractor, Vericon. Their security systems were made up of cameras and monitors and could only be used for live monitoring – they did not have the components available to record footage.
The first CCTV recordings.
By the 1960s, the wide availability of reel-to-reel recorders helped to preserve the data that was gathered by the camera. However, due to the magnetic tape having to be swapped manually, it was a difficult, unreliable and costly process for CCTV installers. The user had to thread the tape from the reel through the recorder and onto an empty reel – unsurprisingly, the take-up for these commercial systems wasn't huge.
The rise of VCRs.
The major development that led to the wide usage of CCTV security cameras, was the innovation of the VCR (Videocassette Recorder) in the 1970s. Essentially, an automatically-loaded reel-to-reel recorder (with the reels held inside a cassette), this type of media solved the time-consuming issue that plagued previous systems. With the user no longer having to be on site to monitor what was happening, the VCR could be set-up and left to run by itself – users could then review the collected data when they wanted to. This advancement allowed the systems to become more commercially viable for businesses.
It should be noted, however, that these solutions were far from perfect. With a limited amount of tape, the cassettes would have to be changed regularly – or recorded over. So if users wanted to store any decent amount of information, they would have to keep a library of cassettes – not ideal if you had limited space.
In the 1990s, the emergence of multiplexing allowed for the video signals from multiple CCTV cameras to be combined and displayed on one monitor. Instead of having to monitor/record on multiple screens, the footage would be sent to one screen and one recorder, saving much in the way of monetary cost (and sheer effort). This was a huge step forward that made CCTVsolutions more efficient, further helping to increase the popularity of CCTV installers in commercial environments.
Digital Security Cameras.
The emergence of digital technology in the 21st century has led to rapid improvements for CCTV systems. By this point, VCR's had been replaced by Digital Video Recorders (DVRs), which made the process of monitoring and recording images much simpler and user-friendly. Multiplexers are automatically included in digital systems, meaning that their set-ups are easier to install and to operate. Digital technology has also removed the reliance on video cassettes, meaning that users no longer have to stockpile media to store information.
Network Video Recorders.
Arriving at the present day, it has now become possible for businesses to make use of Network Video Recorders (NVRs). These systems work by processing and encoding video in cameras before streaming the footage to NVRs for storage or remote viewing. Security cameras that utilise NVRs are particularly useful for businesses who have multiple locations to manage, as they allow for the viewing of various departments at any one time, across the network or internet. The images they produce are also of a much higher quality than previous systems – with high definition (1080p) quickly becoming standard; a far superior quality than older systems .
Thanks to the impressive array of features that contemporary security systems are able to boast, as well as their ease of use, it is no surprise to see that CCTV installers are in such high demand.
