CCTV, or closed circuit TV, security camera systems have been around since the 1960s. They started as black and white television cameras wired directly into a video monitor that had to be watched at all times. The 70s and 80s saw improvements in the form of ways to record video for later viewing. VCRs were still slightly unreliable at the time, but companies discovered that recorded video clips could be used as evidence against criminals who did try to break in. In the 90s, advances in computer technology allowed video from surveillance cameras to be stored digitally. Most recordings were saved to computer hard disks until DVRs and other methods became available.

In recent years the flexibility of CCTV security camera systems has expanded due to the introduction of the internet and wireless networking. Cameras could be controlled remotely and video viewed over the internet. Wireless technology meant that CCTV security camera systems could transmit without cables, making installation easier and systems easier to manage.

CCTV security camera systems have always played a major part in video surveillance and security because they are reasonably secure. Additionally, just the sight of a security camera is enough to deter some criminals from striking. Now CCTV security camera systems are used outside of business too. Wireless technology has become affordable enough that many home owners are using CCTV security camera systems to protect their own homes.
