FAQ: 

1. If use the network video surveillance system, how to deal with the original equipment? 

The original equipment can be modified, but need to increase the video server or hybrid NVR, laying access lines and network equipment and other related equipment.

2.Network video surveillance system video image storage which several ways?

Network video monitoring system provides front-end, center, client three storage methods. The general principle of determining the storage location is as follows:

Front-end storage: If the user's storage image real-time requirements higher while the reliability of front-end equipment can be guaranteed;

Central storage: If the front end does not store the function of the general use of central storage, the other central storage can be used as a backup front-end storage;

Client storage: generally as a temporary video image storage: such as capture, manual video.

3. What are the types of storage provided by the network video surveillance system?

The front-end storage is to store the video recording in the hard disk of the DVR. The center store stores the video recording on the central platform's video server. The video storage is stored in the DVR's own hard disk. The supported hard disk display or the disk storage supported by the network storage; the client store stores the video recording in the client's browser to monitor the disk in the machine

4. What is the current mainstream network video surveillance products?

Network camera (IPCAM), network video recorder (NVR).

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.
