1. Product Introduction
KB1008 GPRS wireless camera system adopts GPRS communication method, which can transmit real-time photos taken on-site back to the monitoring center or monitoring client in real time. The distance is not limited and can be used worldwide. The system is dedicated to security, meter reading, remote monitoring and other fields. The system is easy to use, easy to operate, and extremely practical. The system features are as follows:
Stable performance, never lose packets when transmitting large amounts of data;
The transmission speed is fast, and a photo of 640 * 480 pixels can be transmitted in about 10 seconds;
The server software is mature, stable and reliable. The software has been developed and applied for many years. The multi-thread mode can maintain a large communication data throughput;
The camera software is easy to operate, the interface is very user-friendly, and the user is very easy to understand and use;
The camera software automatically displays the online and offline status of the on-site GPRS camera;
Not only supports remote manual photography and remote automatic photography, but also supports on-site triggered photography;
It is convenient to receive photos, as long as users install the software in any computer connected to the Internet, they can receive photos taken on site;
The system is safe and reliable, and software users have strict password verification mechanisms. The company ID is verified by the server, and the user is verified by the database account;
2. GPRS parameter characteristics
Standard industrial grade products, EMC anti-interference design, strong ability to adapt to the environment;
Independent research and development, embedded 32-bit ARM7-CPU with real-time operating system;
Built-in Watchdog chip, providing multiple reset mechanisms, which can be controlled by software to realize perfect industrial guarantee mechanism;
The working frequency is 850/900/1800 / 1900MHz, and the quad-band can be applied to all countries in the world (including North and South America);
Advanced and strict data communication protocol with error correction and encryption. Data transmission never loses packets, can transmit pictures and flash animation files of more than 100K, and no mosaic phenomenon will occur;
IP automatic registration mechanism can realize multiple service modes and build a complete ultra-large-scale wireless application system;
Remotely modify DTU parameters: support SMS to modify DTU parameters, and network to modify DTU parameters;
IO switch function: It has two switch inputs and two switch outputs. Can be controlled and read remotely. You can set the alarm status threshold, and can set whether the alarm automatically reports the alarm signal function;
Powerful communication backup function: support the automatic switching of the connection between the main server and the backup server. If there is a problem with the main server, it will automatically connect to the backup server;
Powerful server software support, server software application for many years, powerful, mature and perfect;
Support dedicated APN, data center supports fixed IP and dynamic domain name resolution;
Industrial temperature range: Working temperature: -40 ℃ -80 ℃, communication is not affected at -40 ℃.
