The evolution of video surveillance hardware is essentially a journey of continuous breakthroughs and innovations in three fundamental elements: power, signal transmission, and optical technology. Each technological revolution has been driven by higher demands in these areas, propelling the industry forward.
Power supply advancements
In terms of power supply methods, video surveillance camera has undergone an evolution from cable power supply to battery power supply, and then to AOV (Always On Video) technology. Early surveillance camera relied heavily on wired power, severely limiting installation flexibility and usage scenarios. The advent of battery-powered devices brought a revolutionary change, freeing cameras from wiring constraints and enabling true free installation. The latest breakthrough — AOV technology — optimizes power management and low-power consumption design, allowing for continuous monitoring while significantly extending battery life. This innovation effectively addresses the pain points of battery-powered surveillance.
Signal transmission evolution
Advancements in signal transmission technology have also propelled the industry's development. From early analog signal transmission to the digital revolution by IP cameras, and then the widespread adoption of Wi-Fi wireless transmission, each breakthrough has led to easier installations and superior video quality. The 4G technology has further expanded surveillance camera capabilities into mobile scenarios, enabling real-time monitoring anytime, anywhere. These advancements not only enhance surveillance efficiency but also pioneered entirely new application scenarios.
Optical technology breakthroughs
In optical technology, surveillance cameras have progressed from daylight-only operation to infrared night vision, and further to the innovation of black-light full-color technology. Each step has extended the monitoring capability in low-light conditions. The emergence of black-light technology has been particularly groundbreaking, delivering full-color images even in near-total darkness. This advancement has dramatically improved night surveillance performance, bringing a revolutionary change to the security industry.
Vision for future
Looking ahead, with the widespread adoption of 5G technology and advancements in AI algorithms, video intelligence hardware will usher in new development opportunities. More efficient power solutions, more reliable signal transmission, and more advanced optical technologies will continue to drive innovation, offering users smarter and more convenient surveillance experiences. These technological advancements will not only transform surveillance methods but also profoundly impact people's lifestyles, accelerating the rapid development of smart cities, smart homes, and other related fields.
