To be the peaceful town, it has to build in points to monitor in the major area for meeting demands of security. We’ve observed the surroundings and found the issue following:
- The monitoring center built in the committee and the points were sprawling around the center.
- Some of the points are 4km away from the center.
- Lots of trees and buildings between the center and the monitoring points.
- It’d better use the wireless connection due to most of monitoring point are built in the roads, fields and houses.
- There are 23 monitoring spots for transfer the video.
- Monitor the essential area like access,major streets,record the vehicles information, offer high quality pictures to recognize the suspects.
- The control room records the video in real-time in the committee.
- The TV wall plays the front videos automatically or manually, which made of four 32 inches LCD in the control room.

Selecting the device according to the different distance from villages and roads.Because of the complicated area in the Village A which is 4km far away from the control center, we suggest to use the wireless bridge CN351-H created by Todaair with the chip AR9344+SiGe5004L, 5km transmission distance,40MB/S bandwidth, high-quality pictures.
The village B and the surrounded roads are 2km away the control center. Due to the complicated environment, we suggest to adopt the wireless bridge CN322-H that created by Todaair, works with the chip AR9341+SE2576L, 3km transmission distance,40MB/S bandwidth and high-quality pictures.
Install the waterproof and stable HD 130w camera in the essential areas like entry,exit and major streets for outdoor monitoring. As for the public areas such as the fields, ponds and crossings,it’s better to set up the HD 130W camera for the administrators are able to do the remote control to monitor in a full-scale,also improve the whole relations highly with presetting.
Administrate uniformly the front cameras,dome cameras and HD decoders. Monitor the device and the server in real time, proofread the front devices organically, centralize the deployment of users’ authority.
- Adopting the web cameras and the digital video recorder in front, it involves the bandwidth at around 4M and every spots need 12M the most, that’s the reason that use the 300M and 150M wireless bridges at the same time to make sure the enough bandwidth.
- The wireless routers used for the project work with a built-in 60odirectional antenna which is easy to set up. Since the spots are sprawling and the environment is complex, the angle while installing to avoid the trees and buildings.
- Regulate the angle while installing the bridges with the supports to improve the signal.
- 16 ports POE switch for the control center and 8 ports or normal POE switch for the monitoring spots.
- Using the relays to deal with the hindrance.
- The 300M wifi bridge carries 3 or 4 720P camera for lowing cost. 150M wireless bridge is good for one camera is carried and 300M is better to connect with the switch to carry 3 or 4 cameras.
- To mix three frequency 2.4G,2.3G,5.8G to turn off the interference among the spots.
