FAQ:

1.Can I access the full functionality of the system by installing the client software or using the browser?

There are two ways to use CS/BS, that is, after the installation of dedicated client or directly through the IE browser (need to download the relevant plug-in) can directly use all the features.

2.Some industry requirements for video storage time.

Different industries have different requirements on the video storage time, some need 1-2 days, some need 30 days. The same for the public security industry, different regions for the storage time is not the same, so the Ministry of Public Security for this time in the "urban monitoring alarm network system through technical requirements" to make a unified specification: more than 15 days. Some insurance companies in the country to make a unified specification: more than 7 days. The above time requirement is only used as a reference for business promotion, and it is also necessary to decide according to the business needs and economic capacity of the end user.

3.Network video surveillance system monitoring center equipment how to control the big screen?

High-end users of the monitoring center most of the need for video wall display, in the network video surveillance system monitoring center through the digital decoding matrix for digital signal to analog signal conversion, and ultimately to the front-end equipment to switch to the TV wall.

4.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.

5.How do I estimate the storage size?

Choosing the right storage for a video monitoring solution, you first need to estimate the storage capacity requirements. According to the current mainstream compression method is calculated as follows:

H.264 compression: 720P resolution, real-time 25 frames 33G/day

H.264 compression: D1 resolution, real-time 25 frames, 16.2G/day

H.264 compression: HAFL D1 clarity, real-time 25 frames, 300M/hour/channel;

H.264 compression: CIF resolution, real-time 25 frames, 200M/hour/channel;

The following is the video frequency and the storage time to measure the video data storage capacity;

From this table we can basically estimate the type of device that needs to store image resolution in a video surveillance project. For example, a bank needs a D1 video surveillance system, 7 * 24 hours monitoring, data storage can be covered for 3 months, then the total capacity requirements of 1.1TB.

It is possible to use a fixed rate frame frame storage technique, such as a 25-frame/S video file for one month, to reduce it to 15 frames / S without affecting the recording of the recorded information. This can save a lot of storage space.
