AINOPOL Security Surveillance Solutions: A Comparison of Three Networking Schemes for Precise Selection

In security surveillance projects, the selection of a transmission system is directly tied to the stability of video streams, construction costs, and the convenience of subsequent operation and maintenance. As surveillance scales continue to expand, the traditional transceiver-based networking mode can no longer meet the demands of modern security for high reliability, easy scalability, and low costs. With years of in-depth industry experience, AINOPOL has launched three core networking schemes tailored to different application scenarios: Traditional Transceiver Networking, PON All-Optical Passive Scheme, and POF All-Optical Active Scheme.

Traditional Transceiver Networking: A Transitional Choice for Small-Scale Scenarios

Traditional transceiver networking is a common transmission mode in early security surveillance, typically adopting star or chain topologies to achieve point-to-point (P2P) fiber connections.

Network Architecture: Independent optical fibers need to be laid for each surveillance point and aggregated to the central equipment room, resulting in complex wiring that easily causes cable congestion in dense point areas.

Network Equipment: A large number of switches, optical transceivers and optical cable materials are required, with the number of devices increasing linearly with the number of nodes.

Construction Cost: Although the price of a single transceiver is low, the overall cost often spirals out of control due to comprehensive wiring fees, investment in switch relay equipment, and subsequent maintenance costs.

Network Maintenance: Lacking a unified management platform, fault points are difficult to locate. Once a section of optical fiber is interrupted, manual on-site troubleshooting along the line is required, which is time-consuming and labor-intensive.

Intermediate Equipment: Relies on active switches for signal relaying, which not only increases energy consumption but also raises the probability of failures.

Transmission Distance: The transmission distance of multimode fiber is only 0.55~0.8 km; while single-mode fiber can reach 20~100 km, it is susceptible to electromagnetic interference and has poor stability.

Reliability: The large number of active components leads to a high failure rate, and the system stability is greatly affected by environmental factors.

Scalability: Adding new surveillance points requires re-laying optical fibers, involving heavy engineering work and resulting in poor scalability.

Applicable Scenarios: Only suitable for short-distance, point-to-point, small-scale surveillance systems, such as partial areas of small office buildings or factories.

AINOPOL PON All-Optical Passive Scheme: A Cost-Saving and Efficiency-Boosting Tool for Medium and Large-Scale Scenarios

Drawing on carrier-grade passive optical network technology and optimally designed for security surveillance, AINOPOL’s PON All-Optical Passive Scheme adopts a tree-type point-to-multipoint (P2MP) architecture.

Network Architecture: Only one main optical fiber needs to be laid from the core equipment room, and dozens of surveillance nodes can be branched out through passive optical splitters. The wiring is concise, which greatly reduces the consumption of optical cables.

Network Equipment: Mainly composed of Optical Line Terminals (OLTs), Optical Network Units (ONUs) and Passive Optical Distribution Networks (ODNs), with no intermediate active equipment required.

Construction Cost: The equipment cost of this scheme is only 47% of that of traditional transceiver networking. Meanwhile, it saves labor and material costs for large-scale wiring, presenting a significant advantage in overall construction costs.

Network Maintenance: Through unified cloud-based device management, the status of each ONU can be monitored in real time, and fault location is simple and clear. No on-site segment-by-segment troubleshooting is needed, greatly reducing the pressure of operation and maintenance.

Intermediate Equipment: Optical splitters are purely passive components that require no power supply and have a zero failure rate, fundamentally reducing fault points.

Transmission Distance: The backbone passive transmission distance can reach 20~100 km. Moreover, fiber transmission is inherently immune to electromagnetic interference, ensuring stable and reliable image transmission.

Reliability: The passive component design results in an extremely low system failure rate and stable long-term operation, making it suitable for 24/7 uninterrupted surveillance.

Scalability: When adding new surveillance nodes, it only needs to use the idle ports of optical splitters or add additional optical splitters, without re-laying backbone optical cables, enabling flexible expansion.

Applicable Scenarios: Particularly suitable for medium and large-scale surveillance projects sensitive to costs and maintenance, such as smart parks, urban roads, and large industrial zones.

AINOPOL POF All-Optical Active Scheme: An All-Rounder for Environments with Difficult Long-Distance Power Supply

Targeting decentralized surveillance scenarios with difficult power supply and harsh environments, AINOPOL has launched the POF All-Optical Active Scheme, which integrates fiber transmission and remote power supply into one, truly realizing a "one-cable solution".

Network Architecture: Also based on a tree-type point-to-multipoint (P2MP) topology, but adopting optoelectronic composite cables to transmit data and power through the same cable, simplifying on-site deployment.

Network Equipment: Core equipment includes Optical Line Terminals (OLTs), Optical Network Units (ONUs), and integrated devices for long-distance power supply and optical splitting, with support for active relaying in the middle.

Construction Cost: Although the equipment cost is moderate, it greatly reduces the expense of laying separate power lines. It is especially suitable for areas with difficult power access such as the field and tunnels, with controllable comprehensive wiring costs.

Network Maintenance: With the help of a unified network management system, line faults or terminal abnormalities can be clearly located, facilitating easy maintenance.

Intermediate Equipment: Adopts an integrated design for long-distance power supply and optical splitting, which can not only split optical signals but also supply power to remote devices, solving the problem of long-distance power supply.

Transmission Distance: The backbone transmission distance is 8~20 km, and the branch line (the last level) adopts POF technology to supply power for 300~800 meters. It features flexible coverage and strong anti-interference ability, making it suitable for complex electromagnetic environments.

Reliability: With an industrial-grade design, it can adapt to harsh environments such as high temperature, high humidity and vibration, ensuring stable and reliable system operation.

Scalability: Supports smooth upgrading, and new nodes can be connected nearby on branch lines with little impact on the existing system.

Applicable Scenarios: Especially suitable for long-distance, decentralized surveillance environments with difficult power supply, such as expressways, railway lines, oil pipelines, and border security.

Summary of the Three Schemes: How to Choose?

Through an in-depth analysis of the three schemes, we can make a selection based on the actual project situation:

If the project is small-scale with concentrated points, limited budget and low requirements for subsequent expansion, traditional transceiver networking can still meet basic needs, but its shortcomings such as complex wiring and difficult maintenance must be accepted.

If the project is medium or large-scale and pursues low costs, easy maintenance and high scalability, AINOPOL’s PON All-Optical Passive Scheme is undoubtedly the first choice. Its equipment cost is only 47% of that of the traditional scheme, and the passive architecture brings extremely high reliability and a minimalist wiring experience.

If the project faces the dual challenges of long-distance transmission and remote power access in harsh environments, the one-cable solution function of AINOPOL’s POF All-Optical Active Scheme will fundamentally solve the problem, and the industrial-grade design ensures stable system operation under various harsh conditions.

AINOPOL has always been committed to providing more intelligent and reliable all-optical transmission solutions for security surveillance. Whether it is the ultimate cost performance of the PON All-Optical Passive Scheme or the strong environmental adaptability of the POF All-Optical Active Scheme, our goal is to help users build future-oriented surveillance networks.
