FAQ:

1. What is the characteristic of data transmission in network video surveillance system?

Network video surveillance system data flow is large, high real-time requirements. Generally single 25 frames / sec CIF format image stream size of about 384Kbps; single 25 frames / sec DI format image stream size of 384-1500Kbps, the average stream is 900Kbps, single 25 frames / second 720P format Image stream size of 1500-2500Kbps, the average bit stream for the 2000Kbps; In different industries, the user for the required image real-time, fluency requirements are different, according to the actual situation and specific problems.

2. What are the advantages and disadvantages of fiber access?

Advantages: both transmission distance, high transmission bandwidth, security and good security, system performance and reliable. Disadvantages: not yet large-scale commercial applications, coverage is not wide, limited line resources, higher prices.

3. Video surveillance industry on the characteristics of storage needs?

Video surveillance on the storage needs of the following characteristics:

1) the flexibility of the storage capacity requirements are relatively large, the storage capacity of the number of screen quality requirements, the screen

The size of the size, the frame rate of the screen, the length of storage time and other factors, these factors are changes

Will make a large change in storage capacity.

2) the storage performance requirements are not high, but need to be able to meet the long time continuous data read and write, data flow

Large quantity, and less access to requests.

3) The data retention period is different and can be reused after the use of time. The number of general monitoring places

According to save a certain time (such as 10 days), later you can delete or cover.

4.How does the network video surveillance system support alarm linkage and video recording at the same time?

Alarm linkage in general can be divided into front-end alarm linkage, platform alarm linkage, the client alarm linkage. Alarm event triggered by the sound, light, electricity and other alarm output device in the front of the direct output of the alarm message can also trigger the front of the alarm video; platform to receive alarm information can trigger the platform after the alarm linkage: send the alarm message and customer mail, linkage Center video; client received an alarm signal can be immediately reflected in the client's interface to the customer that an alarm event occurred.

5. Can different manufacturers video server connect to different manufacturers network video surveillance system platform?

At present, the manufacturers of video server equipment can only access to the interface has been docked through debugging, because the terminal interface has not completely industry standards, so temporarily can not fully realize the terminal manufacturers and any platform docking.
