Wireless network cameras are network cameras that transmit video signals over wireless networks. The difference from ordinary network cameras is in the transmission of video signals. Differing from the wireless transmission mode, there are two types of wireless network cameras, one is a wireless wifi network camera, and the other is a network camera that uses a mobile communication carrier 3G wireless signal for signal transmission.
The wireless network camera generally consists of a lens, an image sensor, a sound sensor, an A/D converter, an image, a sound, a controller network server, an external alarm, and a control interface.
Lens
The lens is used as the front-end component of the infrared network camera, and has fixed aperture, automatic aperture, automatic zooming, automatic zooming, and the like, the same as the analog camera.
sensor
The image sensor has both CMOS and CCD modes. CMOS is a complementary metal oxide semiconductor, and CMOS is mainly a semiconductor made of silicon and germanium. Basic functions are realized by a negatively-charged and positively-charged transistor on the CMOS. The currents generated by these two complementary effects can be recorded and interpreted by the processing chip as images. The main advantage of CMOS for CCD is very low power consumption. Unlike CCD and CMOS circuits composed of diodes, there is almost no static power consumption. This makes the power consumption of the CMOS only about 1/3 of that of an ordinary CCD. An important issue of the CMOS is that when processing a fast-converted image, the current is overheated because the current conversion is too frequent. Dark current suppression is not a problem. If the suppression is not good, noise is very likely to appear.
The CCD image sensor consists of a photodiode arranged two-dimensionally on a monocrystalline silicon substrate and its transmission circuit. Photodiodes convert light into electric charge, which is then transmitted and output via a conversion circuit.
In general, CCD image sensors are used in devices that deliver superior image quality, and CMOS image sensors are used in products that focus on power consumption and cost. But new technologies are overcoming the inherent weaknesses of each device while retaining certain features that are suitable for a particular application. This section is the same as the analog camera. The sound sensor is a pickup or a microphone, which is the same as the traditional microphone principle.
A/D converter
The function of the A/D converter is to convert analog signals such as images and sounds into digital signals.
The image sensor module based on the CMOS mode has a direct digital signal output interface and does not require an A/D converter. However, if the image sensor module based on the CCD mode has a direct digital output interface, there is no need for an A/D converter, but due to this module Mainly for analog camera design, only the analog output interface, it requires A/D conversion.
Encoder
The A/D converted image and sound digital signals are encoded and compressed according to a certain format or standard.
The purpose of coding compression is to facilitate the digitization of audio/visual signals and multimedia signals; to facilitate the transmission of the signals without distortion in computer systems, networks, and the World Wide Web.
At present, there are two kinds of image coding compression technologies: One is hardware coding compression, which means that the coding compression algorithm is fixed on the chip; the other is software coding compression based on DSP, that is, the software runs on the DSP to perform image coding and compression. Similarly, voice compression can also use hardware-coded compression and software compression, and its encoding standard is MP3 format.
Controller
The controller is the heart of the infrared network camera. It shoulders the management and control of the infrared network camera. If it is hardware compression coding, the controller is an independent component; if it is software coding compression, the controller is a DSP running code compression software, that is, they are combined into one.
Network Server
The network server provides the network function of the infrared network camera. It uses relevant network protocols such as RTP/RTCP, UDP, HTTP, TCP/IP, etc., allowing users to use their own PCs to use a standard browser according to the IP address of the infrared network camera to the infrared. Network cameras access, view live images, and control the camera's lens and head.
Alarm control
The infrared network camera provides a practical external interface for engineering applications, such as controlling the 485 interface of the PTZ, and the I/O port for inputting and outputting alarm signals. If an infrared sensor detects a target, an alarm signal is sent to the infrared network camera. The infrared network camera automatically adjusts the lens direction and records in real time. On the other hand, when the infrared network camera detects the presence of a moving target, it can also send an alarm to the outside. signal.
The basic principle of the infrared network camera is: After the image signal is input through the lens and the sound signal is input through the microphone, the sound sensor of the image sensor is converted into an electric signal, and the A/D converter converts the analog electric signal into a digital electric signal, and then is encoded. The device encodes and compresses according to a certain coding standard. Under the control of the controller, the network server sends the LAN or INTERNET according to a certain network protocol. The controller can also receive alarm signals and send out alarm signals, and send out the control as required. signal.
