Wireless Private Network Solution for Public Security Safe City Surveillance

Safe City is built to achieve urban peace and harmony through the three-defense system (technical defense, physical defense and human defense systems). Targeting different groups, it can provide multiple combinations such as alarm, video and linkage functions. It organically integrates the 110/119/122 alarm command and dispatch, GPS vehicle anti-hijacking and anti-theft, remote visual image transmission, remote intelligent telephone alarm, and Geographic Information System (GIS), enabling real-time linkage alarm for fire incidents, remote visualization and positioning monitoring of crime scenes, and synchronous command and dispatch. This effectively realizes high-speed information transmission, transforms urban security from post-incident control to pre-incident prevention, and improves urban safety and residents’ living comfort.

Public security bureaus at all levels are the core construction and application departments of the Safe City system. As a large-scale and highly comprehensive management system, Safe City can meet the needs of public security management, urban management, traffic management and emergency command, and also cater to the video surveillance demands for disaster accident early warning and safe production monitoring.

How to enhance the public security organs’ capability of social public security control? There are numerous application requirements for video surveillance, mainly including:

Social public security patrol: The video surveillance system enables online visual public security patrol, which is more efficient and covert than the current major patrol methods such as foot and vehicle patrols, with a stronger deterrent effect.
110 police incident disposal: Upon receiving a report, the video surveillance system allows the command center to directly view the dynamic situation around the incident site in real time, supporting effective command and dispatch. The surveillance cameras installed on 110 police response vehicles can monitor the on-site dynamics, protecting police officers on duty, recording on-site images in real time, and standardizing law enforcement simultaneously.
Control of complex public places: The video surveillance system provides real-time monitoring of public security dynamics in complex public places such as night food stalls and the entrances of song and dance venues. It enables timely disposal of potential or ongoing fights and brawls, and the recorded footage serves as evidence for case handling.
Apprehension in high-crime areas: For high-crime areas, the video surveillance system can be used for stakeout and tracking to arrest offenders in the act, enhancing the public’s sense of security for outdoor property.
Investigation of vehicle-related cases: In the handling of vehicle-related public security cases, traffic accidents and the investigation of hit-and-run incidents, the video surveillance system provides video image data, analyzes vehicle movement trajectories, and offers valid evidence for case analysis. It also provides clues and evidence for solving traffic hit-and-run cases and assists traffic departments in crackdowns.

With the continuous advancement of video surveillance technology in public security work, video images and picture information collected and recorded by the system are playing an increasingly important role in public security investigation and case-solving, especially in cracking major and extraordinarily serious cases where video surveillance often delivers unexpected results. As its role in investigation becomes more prominent, video surveillance has earned the reputation of the fourth major pillar of public security work.

Safe City construction has been carried out nationwide for many years. Video technology has evolved from analog to digital, from standard definition (720P) and high definition (1080P) to ultra-high definition (4K), and has fully entered the era of full intelligence featuring front-end AI intellectualization (license plate recognition, facial recognition, etc.) and back-end big data computing. Monitoring coverage has gradually expanded from key areas in core urban districts to remote urban outskirts, suburban areas, towns and villages.

Within urban areas

The construction of the Safe City system mainly relies on leased operator line resources as the primary transmission method. The growing number of monitoring points has led to a steady rise in line rental costs for local Safe City projects, becoming an unsustainable financial burden. Power supply mostly adopts on-site tapping, resulting in high electricity costs, which necessitates effective cost reduction and efficiency improvement. Coordination with relevant institutions also remains a chronic challenge in project implementation. Is there an alternative transmission and power supply solution with better cost-effectiveness, higher implementation efficiency, and easier operation and maintenance?

In urban suburbs and vast rural areas

The construction of Safe City and Sharp Eyes projects is in full swing, yet constrained by the line resources of operators and power supply units, the problems of difficult power supply and difficult networking are more prominent. Especially in remote locations such as river and reservoir peripheries, parks, scenic spots, and along railways, highways and national roads, power and networking difficulties have become major bottlenecks restricting the full coverage of video surveillance in these areas.

1. Difficult power supply

Monitoring points in remote locations even lack basic power supply, making it impossible to deploy any high-tech systems. Constructing new power cables requires huge investment; moreover, the cables are prone to damage over time, and a single break will disable a string of monitoring points, failing to ensure stable operation.

Guoxin Longxin’s iPower2000 Lithium New Energy Power Supply System can solve the power supply problems of monitoring points in Safe City construction. Green and eco-friendly solar energy provides clean power for environmental protection, fully aligning with China’s advocated environmental protection philosophy.

The iPower2000 is an integrated new energy off-grid standalone power supply system, primarily designed to solve the power supply problems of electronic devices such as wireless network systems, video surveillance points and information monitoring points in the IoT industry (especially the security industry) when deployed dispersedly and in outdoor environments. This product series addresses the long-term power supply needs of scattered surveillance points and information monitoring & collection points at reservoirs, river courses, remote rural areas and other locations.

Based on a host core with lithium iron phosphate batteries and high-performance monocrystalline silicon solar panels, the system boasts advantages of simple structure, compact size, light weight and long service life compared with conventional photovoltaic power supply systems. Its innovative AC/DC dual-output mode is ideally suited for the outdoor application of IT systems.

2. Difficult Networking

Networking of information points in remote locations is extremely challenging. Leasing optical fibers or dedicated lines entails high costs, difficult construction and a long coordination & construction cycle, which seriously delays project progress. In some areas, wiring is completely unfeasible, making wireless networking the optimal solution.

Drawing on years of experience in the security industry, Guoxin Longxin concludes that locations such as mountainous areas, hills, lake fringes and road sides are often characterized by complex terrain, and wireless technology is the only viable option to solve the networking problems of border defense surveillance points. However, with communication distances often reaching several kilometers, ordinary WiFi wireless systems or low-end wireless network systems cannot meet such requirements.

Furthermore, poor environmental adaptability (lightning protection, rainproof, wide temperature tolerance, corrosion resistance, etc.), low reliability and substandard quality of system equipment will lead to frequent malfunctions, resulting in exorbitant maintenance costs for public security users and system integrators. Currently, only a handful of mid-to-high-end wireless systems in the industry with telecom-grade or military-grade quality – such as the iMAX Wireless Metropolitan Area Network (WMAN) system – can guarantee such high quality and reliability.

Guoxin Longxin’s customized wireless networking solution for public security Safe City projects, based on the iMAX wireless network system, is the most practical and cost-effective HD video transmission metropolitan private network solution available in the industry today.
