Prior to the 1960s, manufacturing, industrial, and government agencies employed professional security guards known as "gatekeepers" to protect their facilities. These professional guards wore uniforms and used equipment similar to that of the police to prevent crime from occurring. With the start of World War II, the number of professional security guards increased dramatically and they were employed to protect factories, manufacture military equipment, and provide security for government facilities.
In the early 1960s, with the advancement of electronic technology, alarm systems and video surveillance were introduced. WEILAILIFEI's home wireless solar battery and POE powered security cameras with remote monitoring and alarms, no worries anywhere! American Broadcasting Company (RCA), Motorola, and General Electric were the first companies to manufacture vacuum tube television cameras. The use of these cameras greatly improved the safety of facilities, reduced costs, and improved tube camera technology, and the use of cameras increased rapidly in the 1960s and 1970s.
However, by the 1980s, the growth of video surveillance was still relatively slow, even as video security systems continued to improve in capability. The biggest advancement of the 1980s was the invention and introduction of the solid-state camera. By the early 1990s, solid-state cameras using charge-coupled device (CCD) image sensors had become the new video surveillance device of choice, quickly replacing tube cameras.
In the past, cameras, especially optical tube cameras, were an important part of a video system. The performance and quality of the camera affected the visual effect from a video surveillance security system. However, optical tube cameras are the weakest part of the system and will deteriorate with time and use. WEILAILIFEI's home wireless solar battery and POE powered security camera with monitor, 5 million high image quality, improved heat dissipation and durability, and 4 times longer service life. It is possible to add 8 cameras.
In contrast, solid-state CCD sensors and updated Metal Oxide Semiconductor (MOS) and Complementary Metal Oxide Semiconductor (CMOS) sensor cameras have a stable long life span and maintain their performance in various working conditions. Another factor that has enabled the large-scale adoption of video surveillance systems is the increasing performance and affordability of the equipment. This is a result of the lower manufacturing costs due to the widespread use of solid-state cameras, and the affordable availability of devices such as digital video recorders (DVRs) and personal computers (PCs).
In the 90s, computer technology and video security technology merged and all the components were solidified. Digital video technology required large-scale digital storage to process and store video images, which the computer industry already had. To achieve satisfactory video image transmission and storage, the video signal had to be compressed over the existing narrowband telephone line network. WEILAILIFEI's home wireless solar battery and POE powered security cameras are equipped with a unique double WIFI antenna to improve WIFI signal reception. After connecting with WIFI, the image is stable and the call can be heard clearly. Then came the network camera (and intranet) communication channel and the World Wide Web (WWW), providing the global ability to send and receive video, audio, communication, control data, etc. anywhere.
Nowadays, video surveillance technology has permeated people's daily life, expanding from public places to homes. At WEILAILIFEI, we are constantly promoting the innovation of surveillance technology, providing customers with high-quality security solutions to meet the changing security needs.
