25 Video Security Camera Monitoring System Knowledge Points 1

preface:

The installation of monitoring and security cameras seems to be a very complicated system project, but it is not very difficult as long as you smooth the system and operate it by hand. Here is a summary of the 25 problems you will encounter when installing surveillance and security cameras. Let's find out and fill in the gaps!

Body:

1. How do I change the IP address of the security camera?

(1) Open the security camera management interface from the computer browser, find the network option, and fill in the address to be changed;

(2) From the NVR, search the security camera and click Edit to enter the changed address.

2. How to change the address code of the ball machine?

The address code of the network ball machine generally does not need to be changed. There are two ways to change the address code of the simulator:

(1) When the hard switch is changed, there is a corresponding dial switch on the movement of the ball machine, which is generally binary. Turn the switch to the desired address;

(2) To modify the software, call up the ball machine menu through the preset position. There is an address code modification option in it, and then enter the modification.

3. How to determine the lens millimeters?

Generally, divide the distance required by the site by 2 and then by 1000 to get the lens millimeters, and then adjust the millimeters appropriately according to the required shooting angle.

The lens focal length of security cameras can be 2.8mm/4mm/6mm/8mm/12mm, and each product series can choose the lens focal length to meet the shooting needs of various indoor and outdoor environments. Generally speaking, the larger the focal length is, the smaller the angle of view is, and the farther the monitoring distance is.

In the actual use scene, 2.8mm focal length is suitable for narrow environments such as elevators and staircases, 4mm is suitable for larger scenes such as conference rooms and stores, and more than 6mm can be used in more open places such as parking lots, factory workshops and courtyards; The specific selection can be determined according to the needs.

4. Where is the focusing security camera adjusted?

There are words "FOCUS" and "ZOOM" on the side or tail of the security camera, which can be adjusted with a screwdriver.

5. How to select a disk array?

First, calculate the storage capacity required for all front-end security camera images, divide it by the capacity of a single hard disk to get the number of disks, and then add the number of management disks and hot spare disks required for RAID to get the number of array disks.
