Since the first generation of cameras, security cameras have come a long way and continue to innovate with leaps and bounds of technology: from black and white to color, from standard gun-style to all-in-one, from analog to digital, from standard definition to high definition, from non-smart to smart.
A security camera usually consists of a lens, an image sensor, a DSP, etc. The camera focuses the image of the object to be monitored through the lens onto the sensor, which has multiple pixel points consisting of XY pixels, and each pixel consists of a photodiode and associated circuitry. The photodiode converts light into electric charges, and the total amount of collected charges is proportional to the light intensity. These charges are controlled by the associated circuitry, filtered, amplified, and finally processed by the DSP to generate a video signal.
Analog era
In the days of analog surveillance systems, cameras output analog video signals, which were then converted to digital signals using encoders and stored in computers. Analog surveillance systems were first used in high-end markets such as governments and banks, and for smaller surveillance systems such as subdivisions, stores, small supermarkets, and office buildings, analog cameras were a cost-effective choice.
Network era
With the development of network technology, network video surveillance systems have entered the digital era. Network cameras adopt IP surveillance instead of analog surveillance systems, and transmit video data to the end user through the network. Network cameras are equipped with a built-in digital compression controller and a web-based operating system, and can be directly connected to a TCP/IP digital network. WEILAILIFEI's wireless and POE powered security cameras can be remotely monitored by connecting multiple cameras to a smartphone: connect the recorder and router with an LAN cable, install the app, and you can monitor, watch, and talk with your family on various devices such as tablets, smartphones, and computers outside.
The high-definition era
With the urgent need for high definition surveillance, the technology of high definition cameras has been continuously improved, and the image sensor of the camera has come to meet the requirements of high definition cameras with 1000 million pixels. High definition cameras incorporate image enhancement technologies such as noise reduction and image stabilization to meet the requirements of various application scenarios. High quality images are the core feature of video surveillance and are essential in various security applications. WEILAILIFEI's wireless and POE powered security cameras are 5 million high quality cameras, with improved heat dissipation and durability, and a service life that is 4 times longer.
Evolution into the smart era
With the improvement of computing power, the front-end camera is equipped with a built-in artificial intelligence chip, which can analyze video content in real time, detect moving objects, and recognize the attribute information of people and vehicles. At present, applications such as face recognition, vehicle identification, video structuring, and behavior analysis have become common. WEILAILIFEI's wireless and POE powered security camera comes with a monitor, so you can keep track of your pet or baby anytime, anywhere, whether outdoors or indoors. It can be mounted on the ceiling, so you can see every corner of the room without any blind spots. In addition, when it detects motion, it automatically tracks the object continuously and sends an alarm to the app in real time.
AI startups, security manufacturers, and ICT giants are all working to integrate artificial intelligence into security, with security cameras as a key element in the practical application of AI. The development of security cameras represents progress in the security field and must be combined with practical solutions to realize the implementation of the scene. WEILAILIFEI's wireless and POE powered security cameras also support Alexa, so you can check the camera footage just by talking to Alexa.
WEILAILIFEI will continue to promote the development of security camera technology to meet various changing demands.
