When Was Surveillance Cameras Invented ?
Surveillance cameras were invented in 1942 by German engineer Walter Bruch.
1、 Early camera obscura and pinhole camera experiments (ancient times)
Surveillance cameras, as we know them today, have a long history that can be traced back to ancient times. The concept of capturing images through a camera obscura or pinhole camera can be considered the earliest form of surveillance. These early devices were used to project images onto a surface, allowing people to observe and document their surroundings.
The camera obscura, which means "dark room" in Latin, was first described by the ancient Chinese philosopher Mozi in the 5th century BCE. It consisted of a darkened room or box with a small hole on one side. Light passing through the hole would create an inverted image of the outside scene on the opposite wall or surface. This technique was later adopted by ancient Greek and Arab scholars, who further developed the concept.
Pinhole cameras, another precursor to modern surveillance cameras, were also used in ancient times. These cameras were essentially boxes with a small hole on one side and a photosensitive material on the other. When light passed through the hole, an image would be formed on the photosensitive surface. Ancient Chinese and Arab scholars experimented with pinhole cameras to study optics and capture images.
It is important to note that these early camera obscura and pinhole camera experiments were not specifically designed for surveillance purposes. They were primarily used for scientific and artistic endeavors. The idea of using cameras for surveillance emerged much later in history.
The modern concept of surveillance cameras, as we know them today, began to take shape in the mid-20th century. The first closed-circuit television (CCTV) system was installed in Germany in 1942 to monitor the launch of V-2 rockets. However, it was not until the 1960s that surveillance cameras started to be used more widely for security purposes.
Since then, surveillance cameras have become increasingly prevalent in public spaces, businesses, and homes. Technological advancements have led to the development of more sophisticated and efficient surveillance systems, including digital cameras, facial recognition software, and networked surveillance systems.
In conclusion, while the concept of surveillance cameras can be traced back to ancient times through early camera obscura and pinhole camera experiments, the modern form of surveillance cameras emerged in the mid-20th century. The continuous advancements in technology have revolutionized the field of surveillance, making it an integral part of our daily lives.
