A wireless network camera is a new-generation camera integrating traditional cameras and network technology. It can transmit video images to the other side of the globe via a wireless network. Remote viewers do not need any specialized software; they can view the surveillance footage simply through a standard web browser. What is the composition structure of a network camera? To help you gain a better understanding of wireless network cameras, technicians from Kaimorui will provide a detailed explanation below.

Components of Wireless Network Cameras

Image Sensor

There are two types of image sensors: CMOS and CCD.

CMOS, or Complementary Metal-Oxide-Semiconductor, is a semiconductor made from silicon and germanium. It performs basic functions through negatively charged and positively charged transistors on the CMOS chip.

A CCD image sensor consists of photodiodes arranged in a two-dimensional pattern on a monocrystalline silicon substrate, together with transmission circuits. The photodiodes convert light into electric charges, which are then transmitted and output via conversion circuits.

A/D Converter

The A/D converter converts analog signals such as video and audio into digital signals.

Encoder

The digital video and audio signals after A/D conversion are encoded and compressed in accordance with specified formats or standards.

Lens

As the front-end component of an infrared network camera, lenses are available in fixed iris, auto iris, auto focus and auto zoom types, the same as those for analog cameras.

The above covers the main composition structure of wireless network cameras. In addition to the parts mentioned above, they also include a controller, network server and alarm control module. We hope this introduction is helpful to you.
