Xisheng Microvision: Elevator Wireless Monitoring Installation Diagram

The rapid development of science and technology, people's lives have become more and more intelligent, such as elevators in the 90s. Products that belong to rare items have become quite popular today. Whether it is a commercial building, a residential quarter, a factory or a school, the application of elevators is quite common, and there are more and more security incidents. While elevators bring safety and convenience, criminals also provide opportunities to commit crimes, so elevator monitoring has become an important monitoring area in today's society.

On-site environmental analysis:

Because the elevator uses the accompanying cable, the power line, signal line, and control line are all integrated. The elevator runs up and down every day. Over time, the accompanying cable is damaged, which affects the normal use of the surveillance video, and the security problem is not guaranteed. We want to achieve this effect by not requiring wiring.

According to the information provided by the customer, this is an elevator monitoring within the community. There are four elevator buildings in the district, and there are two elevators in each building. A total of eight elevators need to install cameras for security monitoring. Each building has 28 floors, and the monitoring center is located in the interior of one of the buildings. There is an optical cable at the bottom of the elevator shaft to access the monitoring room. Therefore, customers only need to use wireless high-definition image transmission inside the elevator. Customers decide to use a network dome camera for monitoring.

Wireless monitoring solution:

The elevator monitoring is different from the ordinary monitoring because the elevator is moving, so the stability of the monitoring is very high. The elevator is composed of the elevator passage and the car. Within the elevator is a closed environment with relatively few interference sources in the channel and relatively short monitoring distance. The 2.4G digital wireless bridge WS-2D08 can be used to achieve digital transmission from the inside of the elevator to the top of the elevator.

Since the four elevator buildings need to install wireless video transmission, we use the WS-2D08 at the bottom of the elevator car to connect the camera with a wired connection in the car, and then transmit the images wirelessly to the bottom of the elevator shaft, two for each building. The elevators are installed in the same way to set up wireless transmission equipment. Through the switch, the images of the double-row elevators are integrated. Finally, the wired optical cable is used to access the monitoring room host room and the NVR is connected for storage monitoring.

Wireless transmission equipment: WS-2D08

The WS-2D08 is a high performance, high stability 2.4 GHz wireless client product. The product integrates an advanced 802.11n wireless core and dual polarized directional antenna with MIMO 2x2 technology, and the rugged housing achieves IP-65 protection. The product has a reliable, advanced, feature-rich operating system that can provide stable, high-speed wireless network connections quickly, safely, and efficiently. In addition, the WS-2D08 also supports access point mode, which makes the application of the device more extensive, and can be applied to both point-to-point and point-to-multipoint network applications. The WS-2D08's software engine is mature and robust. The device can work in bridging mode and can also work in routing mode. The graphical user interface (GUI) is based on the Adobe Flex design. The interface is user friendly and configuration can take effect immediately. The software contains useful installation aids such as site survey, antenna calibration, delay restart, and spectrum analysis, and is compatible with the industry-leading management tool WNMS (Wireless Network Management System).
