FAQ:

1.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.

2.What is the role of front-end equipment?

In the network video monitoring system, the role of the front-end subsystem to achieve the monitoring point of the sound, video data, switch alarm data collection and audio and video coding compression and network transmission. Front-end equipment mainly includes:

1) image coding equipment (digital video recorder DVR, embedded video server, network camera);

2) audio and video capture equipment (camera, pickup);

3) PTZ/PTZ decoder;

4) alarm input/output equipment (switch equipment, alarm, etc.);

3.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.

4.There are several ways to see the video

There are three ways:

1.C/S (client/server) architecture: the remote PC installed on the client software, each client software directly access the front of the video server or network camera. As if in the local installation of personal version of the virus protection equipment, or that is the manufacturer of direct sales model

2.B/S (browser/server) architecture: in the remote PC does not need to install any client software, only need to have an IE browser, each client access is set up in the specified location of the server, through the visit server image. As if the remote server installed in the local anti-virus software client. Or that is the agent sales model.

3.Brower mode:directly through IE access front-end video server or network camera. As if you were online through the virus for online protection. Or that is through the network for online sales model.

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.
