A trip to the past

Thirty years ago, around the early 1990s, video surveillance for physical security purposes primarily relied on analog systems. Businesses commonly utilized Closed-Circuit Television (CCTV) systems, which consisted of analog cameras connected to video recorders or monitors via coaxial cables. These analog cameras captured video footage in standard definition and transmitted it in analog signals.

Video cassette recorders (VCRs) were also typically employed to record and store video footage from analog cameras, which had limitations in terms of video quality, storage capacity, and remote access. Moreover, VCR tapes had to be replaced periodically and manually.

The monitoring and viewing of live or recorded video footage involved dedicated monitors or televisions connected to analog cameras or VCRs. Multiple screens were utilized in control rooms or security stations to supervise different camera feeds simultaneously.

At this time, the focus was primarily reactive (capturing and reviewing footage) rather than proactive (automated detection and analysis of specific events or behaviors before they become serious emergencies).

Between the 1990s and 2000, significant progress took place in the field of video surveillance, paving the way for more sophisticated and effective security systems.

Some key enhancements were:

Digital Video Recording

In 1999, Digital Video Recorders (DVRs) appeared on the market. The transition from analog to digital technology revolutionized video surveillance, as DVRs replaced VCRs, allowing for higher-quality video recording, increased space ability, and easier retrieval of footage. DVRs digitized analog camera feeds and enabled remote access to video recordings.

Megapixel Cameras

Further, megapixel cameras emerged as a breakthrough technology, offering significantly higher image resolutions than traditional analog cameras. These cameras provided clearer and more detailed video footage, allowing for better identification of objects, individuals, and incidents.

Today’s capabilities

Twenty years later, there has been a significant modernization in video surveillance technology, driven by innovations in digital and network-based systems. The introduction of high-definition (HD) and later, ultra-high-definition (UHD) cameras brought remarkable improvements in video quality. These cameras offer greater clarity, detail, and color accuracy, giving the means for better spotting.

In addition, during the last two decades, IP-based cameras became more prevalent, which permits easy integration into existing computer networks. Power over Ethernet (PoE) technology emerged as well, enabling the transmission of power and data over a single network cable, simplifying camera installations, and reducing infrastructure requirements.

It is also important to note that the development of state-of-the-art video compression algorithms significantly reduced bandwidth and storage requirements without compromising video quality. This optimization has facilitated efficient streaming, recording, and remote access to video footage.
