Who is the biggest winner of video surveillance with optical fiber and coaxial cable?

There are two different monitoring methods in the field of high-definition video surveillance: one is IP high-definition, and the other is SDI high-definition; in SDI high-definition transmission, optical fiber cables are mostly used for transmission media. However, do you know much about fiber optic cable, especially for the monitoring field, what role can it play? Perhaps today we can tell you an answer...

For high-definition video surveillance systems, both the IP network architecture and the traditional analog fiber transmission architecture, both are important future directions for development, especially for the traditional analog fiber transmission architecture, users and engineering companies do not have to go to Adapt to the IP architecture.

Fiber optic cables and the most commonly used coaxial cables belong to the same network cable. Although both of them can be applied to the monitoring field, they have obvious differences. First, in appearance, coaxial cables are thicker than fiber-optic cables. From the internal structure, coaxial cables are covered with a layer of insulated wire that surrounds the central copper conductor; the fiber is made of many fine hairs. Glass fiber plus insulating sleeve.

Secondly, the data transmission speed, anti-interference ability, and price for optical fiber and coaxial cable are not the same. In most domestic or residential markets, the use and penetration of coaxial cable is much higher than that of fiber. This is the advantage of low price of coaxial cable. In terms of data transmission, the standard SD image is used as an example. It is in terms of data stability or data size that the latter can also meet user needs.

Fiber and coaxial cable stations are on the same starting line

Again, for the development of high-definition video surveillance systems, 1080p images take up a lot of bandwidth, so in a special field, optical fiber transmission or slightly better; the former rely on optical transmission, strong anti-interference, confidentiality is good; some say the same Axle cables are affected by bandwidth and 1080p images take up a lot of bandwidth. Looking at the current up-and-down data flow, it is also difficult to achieve high-quality image transmission.

Different materials have different wiring

We also mentioned the issue of image and data transmission. What happens to practical applications? Today, more monitoring is not sold by equipment alone, but by engineering. In the network cabling will encounter those problems?

Optical fiber is a very fragile object, so pay special attention to the wiring of your project. Especially for places with right angles or where cornering is needed, fiber optic cables must not be folded into dead ends, and fragile optical fibers will break and fail to transmit. Coaxial cables are the most common network cables used in homes, and are used in surveillance systems. The BNC connector and the engineering wiring also do not need special care. It is very easy to use.

Different application fields cost differently

Let's look at the difference in their application areas. Due to the difference in the cost of the two cables, there are obvious differences in their application areas. Coaxial cable is relatively low in cost and is suitable for home network monitoring systems. The cost of optical fiber is higher and it is used more for projects such as safe cities. Special emphasis is that the development of high-definition video surveillance has become an indisputable real-time, but in terms of current market applications, both can be applied in high-definition monitoring systems; for imaging results also depends on the storage system and display devices, just as the industry It shows that bandwidth is not the only standard that determines the "HD" picture quality.

Develop diversified monitoring markets

Due to the different transmission media, monitoring equipment will form different monitoring systems. It will also be different for other devices in the system. These two, two different transmission media have led to the diversification of the monitoring system.

The IP-based network monitoring system based on coaxial cable is an open monitoring platform. A network surveillance camera corresponds to an IP address, and its security is worrying. However, for peripheral devices, NVRs, network video servers and other products are IPs. The derivative of network monitoring is the development direction of future high-definition network monitoring.

The traditional analog network monitoring system based on optical fiber cable is a relatively closed-circuit monitoring environment. Especially, the use of optical fiber transmission speed, large data volume and other characteristics, in the analog monitoring market is about to "death", it will pull it from the edge of death Back, especially for HD-SDI products: HD-SDI HD cameras, HD-SDI optical transceivers and other equipment, coupled with fiber optic transmission, you can enjoy 1080p high-definition texture.

A word comment:

Two kinds of different transmission media, let us see the diversified development direction of the video surveillance system, whether it is the development of IP network monitoring or traditional CCTV closed-circuit monitoring system, in the crucial period of this connection, monitoring transmission to the security market provides More room for development.

Written at the end:

Optical fiber transmission drives the development of the high-end surveillance market and is the largest backup force for SDI surveillance products. Coaxial cable transmission has driven the Ethernet monitoring market, making the video surveillance field closer to civilian life, and is the best guardian of the people's clothing, food, housing, and transportation. From large-scale safe city construction to small-scale home monitoring, monitoring the diversified development of the market is the pride of the entire industry. In the face of future market development opportunities, both stand on the same starting line. Who can win and lose, can you negate?
