IP Video Surveillance CCTV Solution Based On EPON

Over more than 20 years, video surveillance systems have undergone significant changes, shifting from the earliest analog surveillance to digital surveillance (very popular in the past few years) to the present burgeoning IP video surveillance. From a technical perspective, the development path for video surveillance systems is characterized by the systems in three phases of the technology: closed-circuit television (CCTV), digital video recorder (DVR), and IP video surveillance (IPVS).
As the security surveillance industry continues to migrate from traditional analogue technology Closed Circuit Television (CCTV) to IP or convergence-based technology more businesses are looking to add IP surveillance to their core network infrastructure. And IP access method has become more and more attention of the object.

The Challenges

Compare with the usual access technology, ADSL remains the dominant position in the past. But, video surveillance is different from the ordinary ADSL application. For video surveillance service, It require the large uplink bandwidth to transfer the video surveillance stream from front end to the monitor center. And 1M-3Mbps bandwidth is required for each channel to uplink the video stream to the center. The downlink channel is used to transmit the control signal and require less bandwidth. Besides, due to the camera often spread widely, video surveillance shows the multi-point to point characteristics.
In theory, the DSLAM equipment can support the1Mbps uplink rate because the distance between users is less than 2 km or even 1 km in downtown.ADSL bandwidth is greatly limited by the transmission distance. It is difficult to meet the IP video surveillance development demand. EPON, as a new access technology, fully meet the requirement of both bandwidth and transmission.Generally, each EPON line can provide 1 Gbps symmetrical bandwidth for 32 (64/128) users, each will be allocated about 30 Mbps bandwidth. The EPON supports a maximum distance of 20 km with enough bandwidth provided.On the other hand,Using passive optical fiber splitter, multiple surveillance point share with one trunk fiber. Optical splitter is a simple device which needs no power and could work in an all-weather environment. It greatly save the construction and maintenance cost.
IP surveillance solution based on EPON technology, break the limitation of traditional solution in remote surveillance and data centralized storage, multi-level network can be easily to expand in future, fully protect customer investment.

IP surveillance solution based EPON

GEPON is applicable to video surveillance along linear areas, such as gas pipelines, highways, and coastal defense areas.GEPON supports several topology structures, such as tree, star, and chain, making for long-distance (5- 20 km) video surveillance terminal access.

IP video surveillance solution based on EPON

GEPON technology adopt tree or star point-to- multi-point topology, network construction is very flexible. Combined with strong service capability, Telesail EPON platform can meet a verity of surveillance network access requirements including limited fiber resource, monitoring point spread in bus or intensive distribution etc.

Tree type network topology as shown below:

Place the camera video codec and EPON ONU before the camera. The video image stream uplink to the OLT in the surveillance center through  passive optical network. The scheduling and monitoring are done by the surveillance software directly over IP networks.

Solution Benefits

The IP network put into place plays an important role in the performance of the video monitoring and capture quality by providing the connectivity, network bandwidth, security and
bandwidth optimisation for good quality video traffic transmission. All of which are important to the performance of the solution to the end user.
With a broad range of  EPON OLT and ONU in the portfolio, Telesail offers Gigabit EPON OLT to deliver full convergence within IP networks. Combined with the latest high-definition camera and surveillance monitoring solutions, these EPON-based surveillance systems offer the resellers a number of advantages:

  • Reduced Installation Cost
  • Operation
  • Quality of Service (QoS)
  • Future-Proof
  • Flexible, Scalable Solution

Telesail EPON OLT support flexible trunk fiber protection function to improve the network realiablity. Any two pon interface in OLT can be set master-slave mode. It can be flexible configure for customer deployment according to the requirement.

Telesail has released multiple optical network unit (ONU) models that provide the passive optical network (PON) access service for video surveillance terminals. These ONU models provide 2/4/8/16/24 downstream interfaces. They support the PoE function, providing power supply for video surveillance terminals using category 5 cables. This function reduces the customer's investments, alleviates reliance on mains power supplies, and accelerates deployments.

While migrating from traditional analogue CCTV to EPON-based IP video surveillance system, operators and users can benefit from reduced installation costs, guaranteed video quality, flexible deployment and scalability, as well as intelligent content analysis.
