In the community monitoring system, wireless transmission scheme plays an important role in preventing and stopping crimes and protecting people's life and property safety. At the same time, improve the safety technology means and design level, so that these units become the representative of advanced management level.
In today's high-definition digital era, customers generally require the use of high-definition surveillance camera wireless transmission, the new generation of WiFi remote picture transmission module to solve this problem, not only simple construction, convenient operation, but also flexible and extensible.
Site conditions: According to the project requirements, wireless transmission is required at the community gate, road, and corner. The monitoring system has 12 monitoring points with a transmission distance of 5 kilometers. In order to effectively and stably transmit signals to the monitoring room, we use WiFi remote graph transmission module wireless digital network bridge point for multi-point monitoring, to realize the monitoring of the whole wireless system.
The overall layout of the community wireless transmission system: the principle of wireless transmission can only be realized when there is no blocking. Because the customer requires the use of high-definition cameras, we use the form of one-to-many transmission. The 12 points in the front end are connected to the HD camera with a digital network bridge for transmission, but two monitoring points are blocked to the monitoring room. Therefore, we need to first transmit these two blocking points to the nearby high roof, receive the high floor with a digital wireless network bridge, and then transmit them to the monitoring room with WiFi remote image transmission module. The remaining 10 monitoring points are received in a one-to-five format at the receiver end, access switches, and then access to network video recorders or computers. The solution to the whole community wireless transmission system.
With the development of economy and the advancement of urbanization, the monitoring project of highway construction is often limited by special geographical environment, which leads to the long cycle of wiring engineering, or even impossible to realize. Faced with these problems, the security industry began to use WiFi remote image transmission module wireless video monitoring to get rid of the shackles of cables, highlighting the short installation cycle, save time and energy. Increase your efficiency.
Compared with wired monitoring, WiFi remote image transmission module wireless video monitoring has the following advantages:
1, wireless video monitoring is easy to set up. The transmitter is set at the front monitoring point, and the receiver is set at the monitoring center. Signals are transmitted via wireless waves, with both ends within visual range.
2, wireless video surveillance is easy to maintain and transfer. Any node on the network can be managed remotely, and devices can be easily moved to other monitoring points.
3.WiFi remote image transmission module has short wireless video monitoring cycle and low cost. The actual cost of adopting the wired option is high, such as the construction cost of erecting the line and the future maintenance cost of the line. The wireless network video monitoring system can accurately, clearly and quickly transmit the image information of the monitoring point to the monitoring center. Through the monitoring software, the monitoring center can understand and master the situation of each monitoring point, and respond and deal with the situation in time. High reliability, high concentration.
With the development of technology, WiFi remote image transmission module wireless video transmission equipment can not only transmit images and data, but also transmit two-way voice. Wireless transmission is not only one-to-one monitoring, but also one-to-many monitoring, more popular with the majority of security personnel. WiFi remote image transmission module wireless video monitoring comprehensive cost is low, only one-time investment, no need to dig trenches and buried pipes, suitable for outdoor distance long, well-decorated occasions; In many cases, users are often restricted by the special geographical environment such as mountain, port and open land, which brings great inconvenience to the wired network and wired transmission wiring engineering, and the cable construction cycle will be very long, or even impossible to realize. At this time, the use of wireless network can get rid of the shackles of cables, with the advantages of short installation cycle, easy maintenance, strong expansion ability, and fast cost recovery. Flexible network, good scalability, plug and play. Network administrators can quickly add new monitoring points to the existing network without laying a new transmission network, adding devices, and easily implementing remote video surveillance.
Introduction of wireless video surveillance technology
Wireless video surveillance is mainly the camera wireless transmission device to send and receive data and video receiving end. Generally, it should be installed according to the distance of the highway to be monitored, but the communication principle is the same.
Second, customer site analysis
The highway tunnel has five point surveillance systems, each with two network HD cameras. The farthest monitoring point of the monitoring center is 3KM, and 10 monitoring signals need to be transmitted simultaneously. The monitoring center can switch between 10 monitoring states at will. The monitoring point can be viewed from the monitoring center, and the back-end can access the NVR of the monitoring center for storage.
3. WiFi remote image transmission module wireless transmission solution
There are 10 HD cameras at the front, two at each point are integrated with switches, one is transmitted, and five at the back end are received. One on one, then integrated with the switch, directly into the NVR.
WiFi remote image transmission module wireless transmission installation is simple, clear image, far distance, trusted by engineers. With the continuous development of technology, wireless transmission is developing towards a more mature direction.
