Shot

As the front lens member network camera has a fixed aperture, auto iris, auto zoom, auto zoom and other types of analog cameras with the same.


Head

You can specify the browser or software within the allowable range at any angle of rotation.


Infrared light

IP Camera without making light of the situation can monitor, record, its principle is that under low-light or no light, the infrared light automatically turn on in order to achieve all-weather monitoring. But in the absence of lighting conditions the video is black and white.


Support

Fixed IP Camera, it can adjust its position to ensure that the IP Camera is the most appropriate monitoring points, to prevent vibration.


Image Sensor

CMOS and CCD image sensors have two modes. Both CMOS Complementary metal-oxide semiconductor, CMOS main


CCD image sensor


Is the use of silicon and germanium, these two elements are made of a semiconductor, through the CMOS transistor negatively charged and positively to achieve the basic functions. These two complementary effects of the current generated can be processed into chips to record and interpret images. The main advantage for CMOS CCD is very efficient. Unlike the two tubes of CCD and CMOS circuits almost no static power consumption. This makes CMOS power consumption is only about ordinary CCD of 1/3, CMOS important issue when dealing with rapidly changing the image, because the current transformation too frequent overheating. Good question on the dark current suppressor little, if suppression is very prone to bad noise.


A / D converter function is to convert the image and sound analog signals into digital signals. CMOS-based image transfer mode


Sensor module has a direct digital signal output interface, no A / D converter; and an image sensor module based on CCD mode if direct digital output interface, also without A / D converter, but since this module for analog IP Camera design, only analog outputs, so the need for A / D conversion.


Audiovisual Controller

After the image A / D converted, the digital voice signal, according to a certain compression encoding format or standard. Compression coding is intended to facilitate the realization of audio / video signal and digital multimedia signals; to facilitate the transmission of the signal without distortion on computer systems, networks and the World Wide Web.


Currently, the image compression encoding technology, there are two: one is hardware compression coding, coding is about compression algorithms solidified in the chip; the other is based DSP software coding compression, that software runs on DSP for image coding and compression. Similarly, you can use voice compression coding compression hardware and software compression, encoding standards such as MP3 format.


Network Server

Network IP Camera server provides network function, which uses TCP / IP, HTTP, SMTP, FTP, DHCP, DDNS, UPNP, NTP


And other related network protocols, allowing users from their own PC using a standard browser, depending on the IP address of the network camera access IP Camera, to watch live images and control the camera and PTZ IP Camera.


Alarm Control Interface

IP Camera provides a practical engineering application of external interfaces, such as the 485 PTZ control interface for alarm input and output I / O port. Such as infrared probe found the target appears, an alarm signal to the IP Camera, IP Camera automatically adjust the orientation of the camera and real-time video; on the other hand, when the IP Camera to detect moving targets have appeared, it may also give out alarm signals. Such as ringing, e-mail alerts, SMS alerts and the like.


Power Adapter

IP Camera to power, in order to ensure the normal operation of the IP Camera. Each IP Camera is equipped with its own power adapter.

9 IP cameras easy editing

IP network cameras not only supports all standard analog CCTV camera function, and provide users with more system functions and can reduce more costs. Because the IP network camera can be plugged directly into an existing data network to be applied via Ethernet, you can save a company thousands of dollars in wiring costs, at the same time, IP network cameras can work independently on the PC, the image is read using a standard Web browser take. Further IP network cameras also saved the company a lot of specific monitoring equipment and systems, because the system can use the machine for real-time IP management and monitoring via the network anywhere in the world. The analog CCTV system requires a special surveillance equipment and specialized personnel responsible for monitoring the image preservation. Create a new era of high-tech surveillance IP network cameras via coaxial CCTV systems and computer networks, continuous transmission of the image signal stream 30 pictures through a standard web browser in real time per second. Technology leader in the development of detection and alarm tracking down include pre / post messages to transmit short messages via e-mail and SMS, applications and centralized wireless and wired technology will promote a clearer image transmission function.


10 edit image compression

Image compression to use more MotionJPEG manner based on the requirements of IP technology, the need for more security monitoring applications, LAN or other media to transmit high-quality images is limited by bandwidth, MotionJPEG compressed mode than H. 26l, H. 263, MPEG and Wavelet compression format and other more welcomed by most manufacturers, its image quality is generated continuously, the format is more appropriate. MotionJPEG format fully supports standard web browser, so no matter the network from any internet user can no additional software specially designed to transmit and display data in real-time image.


[1] compression IP network camera uses can be divided into H.264, M-JPEG, MPEG1, MPEG2, MPEG4 and Wavelet several. Where H.264 and MPEG4 compression for the current mainstream. IP network camera point of view is not divided into audio and audio from several functions. Million high-definition network camera IP-based price and traditional analog surveillance system transformation considerations, another similar remote monitoring solution is based on an ordinary camera plus a network camera server (Videoserver) instead of an IP network cameras, network cameras server, also known as video gateways or video server, its built-in Webserver, embedded operating system is a dedicated video and audio network access equipment, providing real-time monitoring via standard browser imaging solutions.


MPEG4 compression IP Network Camera Mode and M-CAM module, its main principle is as an embedded Webserver. Users on the network can view the camera images on the Webserver browser (such as MicrosoftIE or Netscape), authorized users can also control the camera PTZ camera movement or operation of the system configuration. It also has alarm input and output functions.
