FAQ:
1. How to install Network video surveillance system front-end equipment?
Network video surveillance system system front-end equipment installation needs to be specific for different equipment, in the installation before carefully read the product manual and installation requirements. The standard steps for installing the terminal device are as follows:
1) Unpacking confirm the completeness of the equipment listed in the product description.
2) Check the power supply voltage to prevent the equipment does not match the equipment damage.
3) to confirm whether the equipment working environment in line with the product manual on the equipment operating temperature, power and other environmental
begging.
4)control equipment manual power test, to confirm a variety of working status indicator to normal operation
2. 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.
3. 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.
4. If use the network video surveillance system, how to deal with the original equipment? Do not increase the cost of use?
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. The old transformation involves only one-time costs, will not increase the daily use of the cost.
5. 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.
