Enter the network parameter setting interface, as shown below:
There are four networking methods to choose from: manual IP configuration, DHCP automatic acquisition, ADSL dial-up, wireless network card
Manual IP Configuration
Manually enter the IP address assigned to the camera. The "Subnet Mask"/"Gateway" should be filled in according to the network environment where the DVR is located.
If there is no router device in the network, please assign the IP address of the same network segment;
2. If there is a router device in the network, you need to set the corresponding gateway. "DNS" is to set the IP address of the domain name server (different for each city). Tap Save to save the settings to take effect.

Debugging methodology
Because embedded systems are a As embedded system is a broader concept, so this article takes HCS12 as the main control chip camera group trolley debugging as an example of debugging methods are introduced.
(A) external build circuit wiring CRT monitor
From the analog camera on the power, ground, signal three leads, the camera power supply, and then the video signal line to the TV box video input interface. The VGA-OUT of the TV box is connected to the CRT monitor, thus realizing the CRT display of the digitized camera vision.
This method is a complete hardware level display, which provides the same display effect as the human eye vision, and is of great help to the camera installation and correction of its own physical parameters.
(B) Off-chip expansion of LCD liquid crystal
HCS12 series MCU contains a serial peripheral interface SPI (Serial Peripheral Interface), which can realize the data transfer between MCUs, and its speed is faster than through the serial asynchronous communication (SCI) method.
The SPI module also supports bi-directional, synchronous, serial communication between MCUs and peripheral devices, enabling the expansion of MCU peripherals.
1. display characters in the system operation in the form of characters to prompt the system-related operating parameters. Each character occupies a point column 8 * 6, 6 bytes of data are required to complete the character display only in the programming of the specified bit to write the corresponding data.
Because the LCD module itself does not come with a font, so at the beginning of the program to define the ASCII table character LCD dot matrix data, that is, a size of N * 6 bytes of the two-dimensional array.
2. Display picture analog camera captured by the video signal after the MCU's A/D digitization, the information is stored in a 40 * 70 two-dimensional array, and then the array binarization, it will be able to be displayed in the 48 * 84 resolution LCD module, so that the developer of real-time observation of the camera machine vision.
This method is a combination of hardware and software display method, can real-time tracking display camera-related information, the display will not interrupt the system operation process.
(C) self-written serial communication host computer software
Use the MCU SCI module to send picture data to the PC, the host computer using MSCOMM control programming to read the communication data.
After reading the data, you can use the powerful data processing ability of windows program and picture display ability of the picture data processing;
such as: according to the data on the picture redrawing, filtering analysis of the array and display the filtering effect, will receive the array in the form of a file exported to the computer to provide a source of simulation data.
This method is a complete software display method, only to receive data from the MCU, will be able to realize a series of processing on the PC, to test the effect of graphical transformation, filtering and analysis of the merits of the idea of data simulation have other methods can not be compared to the advantages.
