Network video recorder installation tutorial

Network camera installation:

The operation basis of network cameras is the Internet and LAN. In a LAN, IP network cameras have permission to access locally. , through the relevant configuration of the computer network, we can achieve local monitoring using IP network cameras, and we can also use the Internet to remotely control the cameras.

The camera installation method specifically divides into hardware installation and software installation. The specific installation method is as follows:

1. Hardware installation: Hardware installation is You need to connect to the network camera through an IP sharer. This specific installation process requires that we first connect the network to the connection port of the network camera.

Note that this connection port is an RJ45 connection port. After connecting, then connect the power adapter to the power supply to power on. After the connection is completed, the other end of the network should be connected to the router. superior. After completing these, the hardware installation is basically completed.

2. Software installation: Regarding the aspect of software, I first search for the network camera. When searching for the network camera, you must be careful. After the search is completed, you must Set the IP address of the network camera.

Then access the network camera. After accessing, you need to install the network camera plug-in. After performing these installations, the software installation is complete.

Network camera installation details:

1. Cabling

The layout of the network camera installation is the same as our analog camera, according to the technology If required, or Party A requires, just design the location. After determining the location, design the location of the switch. Generally, the distance of the farthest camera should not exceed 90 meters.

The switch location is generally chosen in the weak current room. If it cannot be chosen in the weak current room, a small weak current cabinet can be set up. If the outdoor camera is used, the waterproofing of the network cable must also be considered, and professional outdoor network cables are generally used. The actual wiring method of digital cameras is similar to the integrated wiring horizontal wiring method.

2. Selection of switch

How to choose the switch at the incoming layer (for connecting the camera)? Should we choose Gigabit or 100M?

There are requirements for bidding technology Yes, the installation requirements come. If Party A does not require it, it depends on the actual situation. So according to the actual situation, how to choose?

The following is a simple example to explain that the code stream of a 720P network camera is 4M About 5M for 960P and about 8M for 1080P. If one of your switches is a 24-port 100M switch, then the maximum number of 1080P machines you can connect is 10, 10*8=80M.

Generally, we use 80% of the data traffic of the switch, which is the limit. For more than 10 1080P machines, it is recommended to use a Gigabit switch and a Category 6A backbone network cable.

3. Selection of network cables

There are tips for choosing network cables. No matter how good the network cable dealer is, we must be sober when choosing network cables, which is related to the entire project. Quality of finish.

The general recommendation is that the 100M network cable should use the national standard Category 5e pure copper wire. How to test whether it is a good wire? Use a multimeter to test the whole box of 305 meters of wire, and measure a single resistance at the beginning and end of the wire. It should not exceed 30 ohm ones are considered good quality.

As for whether to choose 5e or 6 category network cable, it depends on the actual situation. Judging from the current development situation, Category 5e network cables are the mainstream. When designing, if you want to make more money on cables, you can design low-smoke and halogen-free network cables.

4. Storage and display

For small back-end storage projects, choose network hard disk video recorder (nvr), and for large projects, choose storage server. One thing that needs to be explained here is that digital surveillance does not have a matrix and is all connected to the wall through decoders. In terms of image display, whether to use a splicing screen or a monitor depends on the total cost. Nowadays, splicing screens are the mainstream product.
