The first surveillance cameras
The history of the camera began long before the introduction of photography. The camera obscura, the precursor of the photographic camera, is a natural optical phenomenon named after its Latin translation, "dark room". The earliest documented explanation of this principle comes from Han Chinese philosopher Mozi (c. 470–391 BCE), who correctly argued that the inversion of the camera obscura image is due to light travelling in straight lines. By the late 17th century, portable camera obscura devices in tents and boxes had come into use as drawing tools.
The first permanent photograph of a camera image was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Parisian opticians Charles and Vincent Chevalier. Niépce called his process "heliography".
The first photographic camera developed for commercial manufacture was a daguerreotype camera, built by Alphonse Giroux in 1839. The camera was a double-box design, with a landscape lens fitted to the outer box, and a holder for a ground glass focusing screen and image plate on the inner box.
The first partially successful photograph of a camera image was made in approximately 1816 by Niépce, using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light. No means of removing the remaining unaffected silver chloride was known to Niépce, so the photograph was not permanent.
The first true portable digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 2MB SRAM (static RAM) memory card.
The first digital camera of any kind ever sold commercially was possibly the MegaVision Tessera in 1987, though documentation of its sale is scarce. The first portable digital camera that was actually marketed commercially was sold in December 1989 in Japan, the DS-X by Fuji.
The first camera to feature automatic exposure was the selenium light meter-equipped, fully automatic Super Kodak Six-20 pack of 1938, but its extremely high price kept it from achieving success.
The first semiconductor image sensor was the CCD, invented by Willard S. Boyle and George E. Smith at Bell Labs in 1969. The CCD is a semiconductor circuit that was later used in the first digital video cameras for television broadcasting.
The first "Nanny Cam" arrived in 1992.
The first camera with a liquid crystal display on the back was the Casio QV-10, developed by a team led by Hiroyuki Suetaka in 1995.
The first camera to use CompactFlash was the Kodak DC-25 in 1996.
The first camera that offered the ability to record video clips may have been the Ricoh RDC-1 in 1995.
The first IP (internet protocol) camera—the Axis NetEye 200—landed in 1996. This removed the need for a closed-circuit system.
The first consumer camera phone was the Kyocera Visual Phone VP-210, released in Japan in May 1999.

The first security cameras
The history of surveillance cameras is a fascinating one, with their development spanning several decades and innovations. The concept of closed-circuit television (CCTV) or video surveillance, where cameras transmit signals to specific monitors, was first introduced in the 20th century. Here's a detailed look at the evolution of the first security cameras:
The Early Beginnings
It is believed that the first surveillance camera system was developed in Stalin-era Soviet Russia around 1927 by Russian physicist Léon Theremin. However, the details of this system were classified by the Kremlin. In 1942, engineer Walter Bruch designed what is considered the world's first surveillance closed-circuit television (CCTV) system in Nazi-controlled Germany. This system allowed Nazi scientists and military personnel to observe the launch of V-2 rockets safely.
The First Commercial CCTV
The first commercial closed-circuit television system became available in 1949 from Remington Rand, designed by CBS Laboratories and called "Vericon." These early CCTV cameras provided live monitoring but did not have recording capabilities, requiring constant surveillance.
The Introduction of Recording
In 1951, just two years after the introduction of commercial CCTV, the videotape recorder (VTR) was invented. These early VTRs were open-reel devices that recorded images onto magnetic tape. However, they were not widely adopted due to their high cost and large size.
Advancements in Recording Technology
The introduction of videocassettes in 1969 revolutionized the surveillance camera industry. These cassettes were smaller, cheaper, and more convenient than traditional reels, making it easier to switch out recording media. This advancement, along with the arrival of consumer videocassette recorders (VCRs) in 1971, brought surveillance cameras to a wider audience.
The First Video Home Security System
In the late 1960s, Marie Van Brittan Brown and her husband, Albert, invented the modern video security system. Their integrated security system included a sliding surveillance camera, a monitor, four peepholes, and two-way audio. This system allowed users to see and communicate with visitors, providing an early example of interactive home security.
The Digital Revolution
The 1980s and 1990s saw significant advancements in surveillance camera technology with the introduction of digital products and compression techniques. Digital cameras offered improved image quality, longer recording times, and easier storage compared to their analog counterparts. The development of digital multiplexers in the mid-1990s also allowed multiple cameras to record onto a single digital video recorder (DVR), paving the way for multi-camera security systems.
The Rise of IP Cameras
In 1996, the first internet protocol (IP) camera, the Axis NetEye 200, was introduced. This camera removed the need for a closed-circuit system and could transmit footage wirelessly over a computer network. IP cameras marked a significant shift towards modern web and surveillance cameras.
Today, security cameras have become even more advanced, offering high-definition video, wireless connectivity, and weatherproofing. They are an integral part of everyday life, providing security and surveillance in various settings, from homes to businesses and public spaces.

The first video home security system
The patent for the system, filed on August 1, 1966, was the first of its kind. It included a camera that could move between several peepholes to match the height of a visitor, microphones, and TV monitors that displayed the camera's live feed. The system also featured two-way audio, allowing visitors to identify themselves, and a remote-controlled lock.
Marie Van Brittan Brown's invention was a significant milestone in the history of home security systems. However, due to the high cost of installation, it did not immediately gain widespread popularity. Over time, as the technology became more affordable and accessible, companies emerged to commercialize the principles she established.

The digital revolution
The development and advancement of digital technologies started with one fundamental idea: the Internet. Here is a brief timeline of how the Digital Revolution progressed:
1947-1979
The transistor, introduced in 1947, paved the way for the development of advanced digital computers. The government, military, and other organizations made use of computer systems during the 1950s and 1960s. This research eventually led to the creation of the World Wide Web.
1980s
The computer became a familiar machine, and by the end of the decade, being able to use one became a necessity for many jobs. The first cellphone was also introduced during this decade.
1990s
By 1992, the World Wide Web had been introduced, and by 1996 the Internet became a normal part of most business operations. By the late 1990s, the Internet became a part of everyday life for almost half of the American population.
2000s
By this decade, the Digital Revolution had begun to spread all over the developing world; mobile phones were commonly seen, the number of Internet users continued to grow, and the television started to transition from using analog to digital signals.
2010 and beyond
By this decade, the Internet made up more than 25 percent of the world's population. Mobile communication has also become very important, as nearly 70 percent of the world's population owns a mobile phone. The connection between Internet websites and mobile gadgets has become a standard in communication.
While some experts claim that the world has moved out of the Digital Revolution and into the Information Age, others believe that the Digital Revolution has only just begun, as these digital advances are now changing the industrial sector.

The future of surveillance cameras
AI-powered video analytics is at the core of this surveillance revolution, offering benefits beyond simple recording and storage. AI enables more accurate detection of objects and behaviours, such as finding similar objects in footage or detecting unusual situations based on human posture recognition. The development of multi-camera intelligence will allow for seamless tracking of objects, and it may soon include recognizing complex behaviour patterns across multiple camera fields of view. This will enable predictive analytics, helping to identify patterns and anomalies within video datasets and allowing for a proactive approach to security.
Smart sensors and IoT integration is another significant milestone, creating a dynamic ecosystem where information is shared seamlessly between IoT devices and surveillance cameras. These interconnected networks enhance situational awareness by providing contextual insights and real-time data. For example, a video surveillance system can detect a breach and then cross-reference this information with data from other sensors, such as temperature and air quality, to provide a more comprehensive understanding of the situation.
Cloud-based storage and edge computing have also revolutionized how surveillance data is handled and accessed. Cloud solutions make robust surveillance systems more accessible and affordable for small businesses, while edge computing brings processing power closer to the data source, reducing the need to transmit large amounts of video data and enhancing efficiency.
Additionally, the use of drones in surveillance is gaining traction, offering a unique aerial perspective for monitoring extended areas, especially in remote locations. Ethical considerations are essential in this rapidly evolving landscape, requiring a balance between security and privacy through transparent policies, robust data protection, and ongoing dialogue with the public.
