The trajectory of video surveillance traces an extraordinary voyage through technological epochs, and OHWOAI, an eminent name in surveillance solutions, stands as a torchbearer, shaping this narrative with innovation and adaptability. Let's embark on a chronological expedition, traversing the evolution of video surveillance and its pivotal role in shaping modern security.

**1. Pre-1960s: The Sentinel Era**

Before the 1960s, the realm of surveillance was guarded by private security personnel, akin to modern sentinels. Industries, factories, and government entities enlisted uniformed security staff armed with equipment reminiscent of law enforcement gear. These vigilant personnel shielded establishments from potential criminal breaches, laying the foundation for contemporary security practices. As World War II unfurled its canvas, the ranks of private security swelled, safeguarding factories, manufacturing military armaments, and fortifying government assets.

**2. 1960s: Transition to Video Surveillance**

The 1960s heralded the advent of video surveillance, gradually eclipsing the human sentinel role. This era marked the emergence of electronic technology, ushering in alarm systems and the genesis of video surveillance. Frontrunner corporations such as RCA, Motorola, and General Electric pioneered vacuum-tube television cameras, accentuating equipment security, curbing operational expenses, and advancing tube-type camera technology. The technological shift witnessed a rapid proliferation of camera adoption during the 1960s and 1970s.

**3. 1980s: The Triumph of Solid-State**

The 1980s witnessed noteworthy leaps in video technology, epitomized by the ascent of solid-state cameras. Despite functional enhancements and accessory innovations within video security systems, expansion remained measured. A defining breakthrough emerged in the form of solid-state video cameras, emblematic of 1980s video innovation. By the early 1990s, solid-state cameras, harnessing the potential of Charge-Coupled Device (CCD) image sensors, supplanted tube cameras, embracing cutting-edge technology and bolstering overall reliability.

Historically, cameras, particularly Vidicon Tubes (employed before CCD), constituted the heart of video systems. The quality and performance of the video system, and consequently, the visual output, pivoted on these cameras. However, Vidicon Tubes were vulnerable to degradation over time owing to their analog circuitry and intricate design.

In comparison, solid-state CCD sensors, alongside newer technologies such as Metal-Oxide-Semiconductor (MOS) and Complementary MOS (CMOS) sensors, delivered longevity and stability, irrespective of temperature or elapsed time. Swift advancements in equipment performance and affordability, propelled by widespread consumer adoption, fueled the broad application of video surveillance systems in security domains.

**4. 1990s: The Internet-Infused Era**

The 1990s witnessed the convergence of computer and video security technologies, both underpinned by the realm of solid-state innovation. As digital video technology sought expansive digital storage for operations and archival needs, the computer industry was in its prime. The achievement of satisfactory video transmission and storage necessitated compression to enable efficient data transfer over narrowband telephone lines.

With the internet's evolution, spearheaded by the United States' Defense Advanced Research Projects Agency (DARPA), precursor to the World Wide Web (WWW), global communication conduits materialized. The internet, coupled with Intranet communication pathways and the WWW, facilitated global transmission and reception of video, audio, communication, and control data.

In this vibrant continuum, OHWOAI's vantage point echoes a historical continuum shaping the present and envisioning the future of video surveillance. Melding technology, innovation, and purpose, OHWOAI pioneers the future by fortifying the foundation laid by historical progressions.
