【FOCUS VISION】Knowledge Class 2 : Comprehensive Overview of Monitoring Practice

Welcome to the second term of the Knowledge Class! As the holiday season approaches, we want to extend our warmest wishes for a joyful Christmas to each and every one of you. We are thrilled to announce our upcoming welfare class, which aims to enrich your understanding of FOCUS VISION and our extensive offerings in the security monitoring sector. We believe that your participation in this session will provide you with valuable insights and a clearer perspective on our products and services. Let's embark on this journey of knowledge together!

What is a fiber optic transceiver?

A device that converts signals in a network system into optical and electrical signals.

How to configure optical fiber according to actual conditions?

Select the type and number of optical fibers according to the total number of cores and transmission mode required by the optical transmission equipment of the system. Determine the number of optical fibers according to the required transmission distance.

At what distance should the fiber optic transceiver be configured?

Once the signal transmission distance exceeds the network cable (usually 100 meters), it is time to consider using optical fiber transmission.

How much memory does a 3-megapixel camera have for one hour of video recording?

The storage space for 1 hour of video recording by a 3 million camera is about 3G. The required hard disk storage space will vary depending on the bit rate size set by the camera.

What transmission line should be used for analog cameras?

Generally, coaxial cable is used, with specifications of SYV75-5 and SYV75-3. In some special occasions, twisted pair transmitters and multiplexers are also used.

 

What is the maximum transmission distance that a network cable can reach?

 

Theoretically, it can reach 150 meters, but in practice it is limited to 100 meters.

How to choose a switch and how to configure the VCR and switch?

Total number of cameras * camera bit rate = required switch bandwidth. Switch bandwidth = nominal bandwidth * utilization, generally calculated as 50%.

   How to choose the number of hard disks according to the recording time?

First calculate the storage capacity required for all front-end camera images, divide it by the capacity of a single hard disk, and calculate the number of disks.

 

When 3 million is connected to a 16-channel 2 million video recorder, does the number of access channels need to be halved?

 

The number of access channels of a network video recorder = the total bandwidth of the video recorder ÷ the bit rate of the camera. The larger the bit rate, the fewer the number of access channels. Theoretically, the bit rate of a 3-megapixel camera is 1/3 larger than that of a 2-megapixel camera.

 

How to choose platform all-in-one machine and decoder?

 

The platform all-in-one device integrates decoding, management, splicing and other functions. The decoder is only for decoding and wall display (splicing, screen division), which can be selected according to the user's functional requirements.

Conclusion and Commitment

In conclusion, as we wrap up the second term of the Knowledge Class, we hope you carry forward the insights and skills you've gained. Benefit courses are offered that will deepen your understanding of FOCUS VISION and our security surveillance products, giving you the knowledge you need to thrive in this field.We appreciate your commitment to learning, and we look forward to seeing you in our next session as we continue to explore and enhance our collective expertise. Wishing you all a joyous and fulfilling holiday season!
