Home security wiring method sharing

First, the problem to consider when wiring

1, the number of information points

Normally, since the master bedroom usually has two owners, it is recommended to install two information points so that both parties can use the computer at the same time. In other bedrooms and living rooms, you only need to install an information point for your child or temporarily change the location where the computer is used. Especially when you have a laptop, you should consider installing an information point in each room and hall. Restaurants usually do not need to install information points because very few people use computers there. If the cell has an information interface reserved, a twisted pair cable from the interface to the hub device should be deployed to connect the home network to the broadband of the cell.

In addition, two or three information points are placed in the hidden position of the center of the residence and the front and rear balconies, in order to install the wireless access point device in the future, realize the wireless network connection of the home computer, and carry the laptop to work outdoors.

2, information socket location

When choosing the location of the information outlet, you should also pay great attention to it. It should be easy to use, not blocked by furniture, and more concealed and less conspicuous. In the bedroom, the information outlet can be located on both sides of the bed; in the living room, it can be located at the end of the sofa near the window; in the study room, it should be near the writing desk, and the vertical distance between the information socket and the ground should not be less than 20cm.

3, the location of the line equipment

Since the line-collecting equipment is rarely touched, the line-collecting equipment should be located in the most concealed position on the premise of ensuring good ventilation. It should be noted that the line equipment needs power supply support, therefore, it is necessary to provide power sockets for the line equipment during the decoration. In addition, the line-up equipment should be protected from installation in locations subject to humidity, moisture, and electromagnetic interference.

4, away from interference sources

Twisted pair cables and computers should be kept away from washing machines, refrigerators, air conditioners, and electric fans as much as possible to prevent these appliances from interfering with signals transmitted in twisted pairs.

5, the power supply is separated

The power cords used by computers, printers, and hubs should be separated from the power cords used in fluorescent lamps, washing machines, refrigerators, air conditioners, and electric fans to provide separate power supply to ensure the safety and stability of the computer.

6, routing

Twisted pair should avoid direct sunlight and should not be placed in a damp place. In addition, it should be kept away from the frequently used passages and heavy objects to avoid possible friction to ensure the electrical performance of the twisted pair.

Second, the room wiring program

1, two-bedroom home wiring

Two information points are installed in the master bedroom, and both sides of the double bed can use the laptop at the same time. The auxiliary bedroom installation information point is located near the bed of a single bed or near the desk, which is convenient for children or visitors. An information point is installed in the living room, which is located at the end of the sofa or in a relatively concealed location near the coffee table, making it easy to use the laptop to work or entertain in the living room.

In addition, a twisted pair cable is routed from the information outlet provided by the residential community to the hub equipment to implement cell LAN access of the home network. The dian telephone line and the power line should be laid separately, and the distance between them is 20cm. The distance between the information outlet, voice socket and power socket should also be 20cm. The wiring scheme can be referred to the design of the figure, where "." indicates the information point.

Pass the twisted pair into the PVC pipe and bury it in the floor mat. When you need to cross the wall, make a hole in the wall close to the ground. The information outlet is wall-mounted and has a bottom box embedded in the wall. The information socket is 20cm away from the ground and 20cm away from the power socket. The line equipment (hub or switch) is installed in the auxiliary bedroom. It is recommended to use 5 desktop devices, which can be fixed on the side of the desk near the bed, saving space, ensuring proper ventilation space, and avoiding direct exposure of the equipment. Affect the appearance.

2, three-bedroom home wiring

The two rooms are the same, so I won't go into details. Since the three-bedroom living room is usually large, it is conceivable to install an information point on the walls on both sides, which are located at a hidden position of 1 m to 1.5 m from the window to facilitate simultaneous access to the computer. The requirements for integrated wiring are exactly the same as for two bedrooms. The three-bedroom wiring is the same as the two-bedroom, and the "." indicates the information point.

3, duplex home wiring

The design of the upstairs master bedroom and the auxiliary bedroom, as well as the residential broadband link and the two-bedroom, are not repeated here. An information point is installed on the two sides of the hall on the first floor, which are located at a hidden position of 1m to 1.5m from the window, which is convenient for accessing a computer or a wireless AP at the same time, making holes in the floor and walls and penetrating into the PVC pipe. The twisted pair is crossed between the floors of the floor. It is recommended to install the line equipment on the back of a layer of stairs, which is easy to maintain without affecting the appearance. The requirements for integrated wiring are exactly the same as for two-bedroom, where "." indicates information points.

If the cell broadband allows multiple users to access each home and dynamically assigns IP addresses using DHCP, then simply connect the hub to the information outlet provided by the cell using a crossover cable. If the cell does not provide DHCP service, you need to set an IP address for each computer. If the cell only assigns an IP address to each home and limits the number of accesses by MAC address, then a broadband router or proxy server must be used.

When using the broadband router method, use a crossover twisted pair cable to connect the WLAN port of the router to the information socket of the cell, and then use another crossover cable to connect the router's LAN port and the home hub device. If the proxy server mode is used, if Windows is used. For ICS, two network cards are required. One network card connects the cell and one network card connects to the home network.
